Tech that includes the word "Virtual" | Cisco CCNA 200-301 Quiz

[Music] [Applause] [Music] all right nimble raven number one in followed by witty mouse it's great to have everybody here and we are gonna start in about nine minutes so get logged in get comfortable get a sip of water or something that'll help you and i think we have like i think it's like 12 13 questions today that all have the word virtual in them now it's not covering every possible technology in cisco land that use the word virtual but sorry frosty master i got to be pretty quick in the day to get the first one in but i'm glad you're here fantastic to have you here so the um the word virtual appear appears lots of places but these are gonna be ccna focused topics like hsrp and fhrp with their virtual ip addresses a switched virtual interface a virtual private network um what else um a couple other times so i made everything surrounding the word virtual and hopefully we'll have a lot of fun together solid shadows in the house i see uh blended inners in the house good to see both of you kel phil's here jesus is here vicente is here all right all right all right nick003 is here james casey's in the house good to see everybody all right i love how nick you just put it out there i'm dazzled sable i don't mind telling everybody who i am way to commit love it you're gonna everybody's in a safe place here all right shadow's taking his first shot at nrc tomorrow that's awesome good luck all right austin texas vicente great to have you here hello mark hello sid there's dan aka blendinator wishing everybody good luck with the super sticker i appreciate the community and the support and the uh the help that we're all giving to each other it's fantastic if you're brand new to the channel hey max if you're brand new to the channel my name is keith barker i have been working with networking in it for a little over 30 years started my it career in 1985 when the pc was fairly new and love it have always loved it and my goal is even though i can't have a direct personal relationship with everybody who's on the channel i do have a really great relationship with a nice handful of people but my goal is for me to be a resource for anybody who wants to re refresh on the fundamentals or to start with networking and learn the fundamentals and my goal is to provide you a quick ramp up in that process it'll it'll change your life it's changed my life i remember times in my life when i i didn't know anything about networking nothing i still remember when i didn't know anything about virtualization like how does that work and what is that all about which is yet another uh term that we're going to talk about today with the word virtual so anyway i'm grateful for the opportunity to get to you know have some contact with many of you and provide some service for many of you and i appreciate the community we also have discord that we have a server there we have over i think 10 000 people there now too so if you are studying for a ccna here's a couple recommendations i would have for you number one get a course it could be a book give a video series something formal or structured that covers in order all the parts of the blueprint secondly prepare yourself to lab almost everything up it's free netacad that's cisco's network academy it's free to sign up there you can download the emulator called packet tracer for free actually it's a simulator but it covers almost all the topics you'd ever want to practice with and it's very quick and easy doesn't cost a dime uh so get a course get the emulator or simulator net from cisco and then third put your head down and go to work and just keep on working this is a lifelong opportunity to get in the world of i.t and keep learning and keep getting better and it's i remember when i was working on my first cci back in like 2000 i got my first one in 2001 and i spent about eight months four to three to four hours a day four to five days a week just studying and prepping labbing for my cca and i did it i was able to pass it the first time but it was only because i spent eight months doing that and it's amazing how much i've i've keep on learning every week every week in the well let me get back to my point so my point was if you're studying for ccna or you want to reinforce the fundamentals join us put it on your calendar schedule the time every saturday at 10 a.m pacific on my discord server our discord server it's free we have an office hour where you can come and bring your questions love what you're studying or can you help reinforce the concept and it's an open forum to ask questions primarily of me but this saturday i have another commitment so dan has volunteered to go ahead and moderate so thank you dan for that also known as blendinator here or troubled inside the discord server so thanks for that and then every sunday at 11 a.m pacific we have a quiz like this one so i would encourage everybody if you're serious about you know taking that next step or reinforcing the fundamentals schedule those two blocks of time they're both free and we are happy to help and we're glad that you're here part of the community all right let's see else who else is logged in all right sid is here max is here abdulkaram i'm my accent and pronunciation present great but it's great to have you here dime is here eduardo is here dante oh testing october 30th ccna all right uh dante my recommendation for you is about a week at least a week before you take your exam uh go through my playlist on youtube which is a recording of many of these quizzes we've been doing this almost two years now and i've got 50 or 60 that i've kept in a playlist that you can review and go through and the secret is to go through the questions pause it before you see the answer and then be really honest with ourselves and say do i know why this is the right answer do i understand the technology if you don't spend a little more time studying it but that's a great way to help verify all right and kaiser is saying i passed my ccna on thursday and kaiser is still here with us today awesome oh you're so welcome for the quizzes big part of my success oh oh by the way i'm joyful cat let's see if i make the podium well i'm rooting for everybody and kaiser i'm so proud of you for putting in the time and the effort you know um this life we have is short i mean at least in my generation and the generation we're currently in i'm probably not going to make it past a hundred so like in 15 20 years from now that may not be true for other people but for me it's short let's live this life let's make meaningful relationships let's help our brothers and sisters a stock must not take crap from anybody at the same time those are not mutually exclusive we can you know put our heads down do great work improve our lives don't take a lot of gut from too many people i'm often motivated by the way by individuals in my life and i i have several examples who've said you can't do that like oh yeah watch me like my first cc i had so many people you can't get a cci you can't get it done and you can it's just a matter of time and effort and consistency also being kind to yourself at times be kind to yourself if you have fallen down and you're getting back up be really kind yourself um but if you're not doing what you know you need to do don't be so kind to yourself like oh use some anger i mean if you get angry because you're not doing what you need to do fix it and do it quietly don't you know don't waste the energy tell you know griping to the world just shake your head get the dust off stand up start walking again life isn't fair never has been however the harder we work in the direction where we want to be is very likely to yield results maybe maybe we're not going to be astronauts well i'm not studying to be an astronaut but maybe we're not going to be you know some lofty amazing you know goal that we want but i can tell you this the person who takes steps in the right direction is going to be better off than the person that doesn't take the steps all that to say i'm glad you're here welcome to the community if you're brand new my name is keith barker we're gonna start here in just a few moments with this quiz and uh yeah kaiser congrats all right daniel i just passed the ccnp encore exam on friday with help from cbt nuggets videos daniel that is a tough exam congratulations that is tough i i walked into the exam i i heard from a friend another cci oh it was easy so i walked into that exam this is last year whatever it was and i took it i thought man they're asking stuff from all over the board they really want me to know this stuff and some of the stuff like well i can't tell you what it was but there's a few technologies that i hadn't seen in like a decade and they were on that exam i was like wow man all right um bellahi is here hello blah welcome welcome and let's see here also if you do me a huge favor if you have if you've already logged in um and you haven't already done so just type in the location of where you're taking this exam from it could be the state or the city or the country or the hemisphere or the continent whatever you want to put it's always fun for me to see what a amazing international audience we have all right scorpio is here emmanuel's here ccna certified yes says manual awesome all right and s smooth is asking uh isis is that that is not part of the ccna however i i would recommend for everybody to be aware of how administrative distance works and i'd also encourage you to be aware of what the administrative distances are for bgp internal and external eigrp isis rip ospf static routes and if i didn't say eagrp that too wow kenya france texas belarus uh belarus bulgaria norway kenya l.a poland sudan greece moscow nigeria oklahoma armenia connecticut netherlands oh my gosh it makes i'm just so happy to have everybody here venezuela granada maryland canada canada uh morocco oh i'm so pleased i'm so tickled thank you everybody for showing up and make this part of your regular schedule um it's only like an hour uh every sunday sometimes a little more sometimes a little less and that's a great refresher help you remind yourself how things work and ethiopia ethiopia is in the house india is in the house congo's in the house colombia welcome everybody let's let's get this party started here we go uh my name is keith barker it's great to have you here this is tech for the ccna that includes in some fashion the word virtual and here we go here's question one it is multiple select a switched virtual interface svi on a multi-layer switch may be used for what [Music] [Music] uh [Music] so [Music] [Music] nice work so one of the these questions that i'm putting up here um a lot of them and the way cisco was going to ask you as well is they want to know do you understand the technology and so if somebody knows what a switch virtual interface is which is a layer 3 logical interface on a multi-layer switch that has an ip address either ipv4 and or ipv6 and that's what it is so if we know what that is then we can say well that could be used for management because i could have a switch here and we could remotely connect to that ip address for management uh in fact uh let me show you a quick example of that let me go ahead and bring out here i have a little pc it's it's virtualized and i'm going to connect to i'm going to telnet oh keith you're using telnet [Laughter] before i tell that to that switch let me ping real quick just make sure i have connectivity ping if i don't this would be a very short demo 2.0.254. yeah it's working all right i'll do a control c to break out of that and let's do a telnet over there so right now i'm telling it to this switch and i'm logically connected to that switch uh to its one of its svis so whether it's a multiplayer switch for with routing using those spi's or a layer two switch that still has an spi for management that's a uh that's what it can be used for so we do a show ip interface brief it shows right here that i'm connected to a logical layer 3 interface a switch virtual interface it's called vlan 10 don't not to be confused with the actual layer 2 broadcast call broadcast domain called vlan 10 which this spi supports and there's its ip address and then we do a who or show users that would also do it this is showing that logically i'm connecting to this device to its ip address on that layer 3 interface logically through vty line 0. all right that's fun okay so let me go ahead and remove all that boom all right alien get that out of the way and so it can be used for management it can be used for ip routing if we have routing enabled on a multi-layer switch it can use the svis for routing purposes and clients could point to that sbi the ip address there on that local vlan as their default gateway nice work we're off to a super strong start bronze crab purple sphinx it's fun for me to say that word uh diplomat raven dazzled sable and epic glider also i was looking at the the comments regarding wherever he's coming from and i didn't have a chance to read every possible location but i am looking that list and um if i didn't mention your country state or location by name uh just realize there's just too many for me to do that but i'm glad to see you all here all right here we go question 2 of 15 which ipsec protocol provides privacy and encryption for a virtual private network [Music] so [Music] and uh got a question saying was that the ubuntu bloop sound what happened in the background i had this computer here and i i mistyped something i had to clear it off and that was a burp came through on the speaker sorry about that but that was uh that was from a linux machine okay it's aes is an algorithm an encryption algorithm that's used as part of ipsec that provides the encryption of the privacy so sha is wonderful it's a data integrity hashing algorithm diffie-hellman is used dh is used to establish shared secret keys and ah authentication header doesn't provide any encryption it just does data integrity but no encryption nice work ah nailed it here we go question number three of 15 with these three hsrp routers who responds to an arp request for the virtual ip [Music] so [Music] [Music] all right i also just noticed that antonia states i finally did the exam last thursday after studying a very long time and i passed congratulations that's amazing fan fantastic work all right with these devices which responds let's take a look at the media real quick let me grab a pen so with a first hop redundancy protocol the goal is to have an ip address that clients can use as a default gateway normally handed out that information their default gateway would be handed out with dhcp and they're in hsrp which is cisco's implementation there's only one device that's going to respond and take care of like arp requests and forwarding on behalf of that ip and that is the active router so if we look at these three routers uh the active router is not this guy because he says he's seeing it somewhere else here we go so the active router is local that means r10 is the one router in this hsrp group this uh that is in the virtual the supporting the virtual ip address and that's how virtual ties into this question with the virtual ip address all right here we go and uh purple sphinx oh knocked out of first place but dazzled sable you might wonder well wait a second wait a sec ah i'm getting all these correct how can i not be in first place the answer is the faster you answer correctly the more points you get so i would say take as much time as you need focus on making sure you understand what the question is answer as best you can and then also make a note of where you might need to study a little bit more all right here we go question number four multiple select based on this output that's coming up in a moment what is true regarding hot standby router protocol [Music] so [Music] [Music] so [Music] all right so um someone arsenal was asking about more laps i've got uh 20 or 30 packet tracer labs of varying difficulty most of them targeted at ccna level at the keithbarker.com so you just go download this for free um fantastic it's using the non-default priority so as we look at the output here the thing is when i see a question like this we don't have to worry about answering every you know how we only have to worry about answering the the question at hand we don't have to worry about all the output so this says we're looking at standby regarding how it's configured on this sub interface it's using version 2 of hsrp it's diffi it's group 20 and also the mac address is going to represent that too so here the last two characters of the mac address is the uh the group number in hex so in hexadecimal the values are 1 16 32 and so for group 20 which is uh would be 16 plus 4 more that's why 14 in hexadecimal is a group i just totally messed up say a decimal 20 is equal to a hexadecimal 14. so that's why that's that also that question may come up a little bit more in another quiz question coming up so you might want to remember that and let's see here it has a non-default priority because the default is 100 and it's it is using the default mac address all right fantastic let's see how we did on that and survey says really really well congratulations okay top of the list here bold new bronze crab epic lighter purple shrinks dating lobster dating lobster maybe there's an app for that i don't know daring lobster congratulations to everybody who's uh on the board and still striving your way to the top here's the next question which cloud model makes the customer responsible for operating system patches on a virtual machine [Music] so so [Music] [Music] all right all right pretty good i do want to answer a quick question from the queue and then we'll continue on a little bit bigger somebody asked um they asked i just quote it it says keith hsrp is not in the syllabus for this blueprint can you throw some light upon the same yeah so right here this is section 3.5 of the ccna blueprint the current one describe the purpose of first top redundancy protocol uh so we could say for a fault default gateway and it's not asking to configure but uh i you know as far as a question regarding 3.5 they're very likely going to ask a question about how does it work or how does it operate and that would that could include vrrp which is a open standard first top redundancy protocol or hsrp probably not gateway load balancing protocol which is yet another option for that but that's that's where this comes from with the hs the first top redundancy protocols hsrp and vrp should be aware of how they work and if you have about 10 minutes you could lab it up and confirm all right so having that out of the way let's go ahead and uh take this question which cloud model makes customers responsible for operating system patches on a vm most of you got that right fantastic work let's talk about why that is so let's imagine that a customer wants to buy some cloud services basically cloud services is a fancy way of saying somebody else's stuff right their servers their stuff they're providing for you so you can just rent it instead of having to have it on-prem so let's imagine that this represents uh networking and this is uh let's call this a hypervisor and let's call this a an operating system and we have apps and data and services so if we wanted to go up let's say the amazon web services and we want to rent a whole server which is going to be virtualized for us uh but that whole server basically we're responsible for everything for our customer we're responsible they'll do the hypervisor and virtualization for us but we're responsible for all this including the operating system so that would be infrastructure as a service some companies they don't want all that they may not need all that they may just want an environment where they can develop software they don't have to worry about the underlying operating system or anything else it was a platform for creating their code an example that would be platform as a service and then some customers may want i should probably put apps up here some customers don't want to deal with anything except for the application and that software as a service an example of software as a service would be salesforce where they host everything in the cloud and all we do is securely connect to it run the apps and we're good to go so uh in infrastructure as a service the customer would be patching the os and working with their system and so forth uh in a truly iis environment where they have learned they're renting logical networks if you will up in the cloud and then platform as a service is less and software as a service the customer is responsible for even less that's a fairly high level overview of it so that's how that works and here we go first place bronze crab all right everybody's doing great here's question six what what i was gonna say which but what type of interface is considered a virtual tunnel interface [Music] [Music] [Music] wow that is absolutely fantastic a gre tunnel interface with an ipsec profile perfect answer i'd like to [Music] take a moment and show you something pretty darn cool and that is this oh i have to log in again let me log in this is a network emulation tool called even g and i'll make it a little bit bigger okay so i just want to give you a quick uh tip something yesterday in the office hour so yesterday long story short we had extended office hour yesterday i had to fix a couple problems then come back a little bit late but uh as i revisited we had some questions regarding uh gre and ipsack and i just want to take a moment to give you a little tutorial appropriate to that last question and that's this in the old days we used to have uh build an ipsec tunnel i'll build it right here that would logically connect two places together like from site one let's call site one left to site two on the right and what happened is these routers if there was a router or firewall either way they would identify traffic that we could train them say traffic from 10.1 going to 10.2 anything when you see that traffic mr router just don't forward it normally but encrypt it send it over the encrypted tunnel which is using aes usually for encryption services and ship those packets over to r2 who will then decrypt it and then forward it on its way whether it's to tell a telnet session to switch one or going to this pc whatever it is and we used that with crypto maps however if we wanted to run a routing protocol like rip or eigrp or ospf those are all examples of dynamic routing protocols and they also all have something in common that is they are they will share routing information with devices that are directly connected on the same network as they are so in this the problem with the old crypto map model is that r1 and r2 are not on any common network they're just taking packets one by one encrypting them shipping them over this guy decrypts it forwards it but there's no common network they can't be neighbors across like the internet with these routing protocols because they have to be on the same network so we have another solution that's very relevant for you as a ccna and let me go ahead and share with you what it is it is this instead of building an ipsec tunnel we use something called g-r-e generic routing encapsulation and we make a tunnel interface like this and that tunnel interface we basically say on router 1 hey i want to make a new tunnel interface pick a number between one and like 110 billion it doesn't really go that high but you just you create a logical tunnel interface and you say hey the beginning of this tunnel like a tunnel has two ends so on this router you say the big the beginning of the tunnel is here and the end of the tunnel is the iep address that's reachable over here on r2 and then you give it an ip address like 10.11.11.0 is the network this guy could be dot one the other end of the tunnel could be dot two and the same thing over here r2 you create a gre tunnel it just say interface tunnel whatever number you want give it an ip address you specify where the source is you specify where the destination is and it logically builds a tunnel so these two routers over this logical tunnel interface they believe that they're both on the same network the 1011 level network and as a result they could build um they could be ospf neighbors or eigrp neighbors or rip neighbors because they logically have this tunnel but in reality the traffic that was going back and forth like the multicast traffic which m-u-l-t-i-c-a-s-t all those routing protocols use multicast for hellos and advertisements and so forth and so multicast traffic is when it's sent it's going to be sent over the tunnel just basically encapsulated in gre shipped over the tunnel and received to their side so if you want to have two devices that can run routing protocols that support multicast we would want to use the gre tunnel in fact you know what let's do this um i'm going to take a little bit of liberty here and give you an example so here is router 1 and router 2 which is here's router 1 side let's do a real quick show ip interface brief okay so right now this has no tunnel interfaces uh this is the 15 network and on the right there's the 25 network so if we want to create a tunnel interface it would go something like this and to speed it along i'm going to go ahead and just use a little copy paste action and copy this bring it over right click and so we're going to go into configuration mode i'm creating a new tunnel interface this is the month and day of scientist that's his name on discord who brought up the question and so i'm going to create a tunnel interface called 1110 i'm supposing the tunnel source is the ip address associated with gig zero one you could also put in the actual ip address there then the remote end of the tunnel is 25222 which is our two's reachable address and then i'm giving that logical layer 3 network that's going to be accessible on this tunnel interface the network address of 10 11 10 and a host address of dot one with this mask so we'll paste that in boom and then we'll do the equivalent over on the other side on r2 so we'll make a road trip so we're gonna go to r2 for a moment and here on r2 boom let's go ahead and so the address here is going to be 10 11 10 2 and the source is r2 and the destination is going to be r1 we'll click on paste and because i have a routing protocol running those guys just became ospf neighbors across this cloud which could be across the internet so if we do a something like show eigrp neighbors uh that's not even a command show ip eigrp neighbors that's more like a command all right and so there's our neighborship and if we do a show iprout this guy thinks that he is directly connected to that 10 that network right there 10 11 10 and he's also learning routes these the d is ea grp there's the administrative distance for eagrp and we should be able to reach networks in fact this pc here uh right here in fact let me bring them up this pc right uh right here pc1 it we're on the 1010 network we can verify that real quick with ip address and i can make that bigger so his ip address is 10 1050 and if we did a a ping for example over to the switch at 10.2.0 dot was it 254. basically if i did that ping that's traffic going from this pc to the default gateway who's now going to send it over the gre tunnel and to go ahead and reach the switch in fact let's do uh one more exciting thing it's even better as a demo let's go back to um the pc for a moment there it is and instead of doing a ping let's do a oh also let's capture this let's capture the traffic and show you so i'm just going to right click in my topology click on capture i'm going to capture all the traffic on gigs 0 1 here so we can actually see the gre traffic as it's being sent over the cloud so i'm going to accept the defaults here and let's go back to our pc and let's do an ssh no that's let's do a telnet because ssh would be more secure so we'll do a telnet and we'll go over to 10.2.0.254 and we're in so here i'm connected to the switch we just show run a few space bars there's the running configuration on that switch if we open up a browser so unfortunately here let me make this bigger and zoom in a little bit here in this packet capture i'll go ahead and click on stop this packet capture it's capturing all the traffic and look at the so here's a telnet piece this is showing layer 3 which is then pointing to the next protocol of gre which then has encapsulated the original packet and unfortunately if we're sending it over the internet or any entrusted network we right click here and say follow and just follow the tcp stream you'll see it's not uh what do you call this bad news yeah because everything we typed that got sent across the network even though it was encapsulated in gre and even though we can have routing protocols that are neighbors there's no encryption here and so we we definitely wouldn't want to use insecure protocols like telnet uh without any some other type of protection so we'd want to use ssh and protect all this but this is this is bad news all right so let me go ahead and close that and let me close that and let's talk about what we would do to protect it so now we have a gre tunnel between r1 and r2 if we wanted to protect that what we could do is we could apply what's called an ipsec profile that says hey any traffic that comes in or out on this gre tunnel i'm going to go ahead and overlay on top of it ipsec and so to do that and it's really easy to do i i did most of the heavy lifting in the background but if we want to add the ipsec to it we could do this go back to our command line we'll go to r1 here in r1 i'm just going to go to the interface i'm going to specify the tunnel mode and then a tunnel protection profile called our ipsec profile so i have the back end stuff is all set up to make that work but i'm just applying this profile to it we'll click on paste we'll go to r2 go ahead and paste and that's gonna bounce because it things changed and now let's do this let's go ahead and let me go back to my window my computer here and do a exit all right and let's do a capture so we'll do a capture of traffic on gig 0-1 just as a demonstration of capturing the traffic which is now going to be encrypted because of the ipsec profile and ethernet okay we'll let that run on the background and let's go back to our pc so at our pc here if we do that same thing with telnet and we're still connected and we do a show run all that traffic is going back and forth but now it's being protected with ipsec so over here on the left i'll go ahead and click on stop here make that a little bit bigger and i'll make that bigger too so now we have esp and so effectively this says here's what the internet sees they see traffic coming from one one one that's router one on the left going to twenty five two two two that's r2 on the right however at layer four it's protocol 50 so if we look in the ip header it's pointing to the next protocol which is right here protocol if i scroll uh there it is protocol 50 the next protocol and then in that layer 4 header the esp header it has the security parameter index to identify the session the security association but check it out all this other data is encrypted no one knows because if somebody's eavesdropping on the internet or across that network even though it's gre traffic which isn't normally protected we've added on top of that ipsec with an ip6 profile so long story short if you want to use tunneling protocols you can use things like gre so you can get routing neighborships and support multicast traffic and if you want to protect it you'd slap on the ipsack for the encryption as we're seeing right here all right so that's a bunch of fun i mean i've been doing vpn tunnels for decades and uh there's lots of different ways of implementing them but the key is don't use insecure protocols across public or untrusted networks because people if they eavesdrop on it and there's lots of opportunity on the internet for that they can see what's actually going on together passwords and so forth all right all right let me go back here and uh let's keep on moving on here is question number seven what is true about hot standby router protocol on this router which is r20 so [Music] [Applause] [Music] uh [Music] all right it has a non-default priority the default is a hundred this guy's got a priority of 106 and all the others were not true all right nice nice nice also there was a question asking about um let's see here uh can you do loud like that in packet tracer packet tracer does support basic ipsec in the cisco bloop in the ccna blueprint if we bring it in and we'd like to look at uh i'm just doing a control f here for vpn so describe remote access and site site vpns now when it says describe that doesn't mean hey be able to configure and troubleshoot this it really does mean describe like what are the options how does it work the concepts of it like a gre with ipsack or a crypto map or just the basic concepts and how it works you can use ssl for vpns that's also an option so packet tracer does support and it's free so as a recommendation if you are studying for your ccna unless you've got a lot of free time i mean just like tons and tons of free time that you don't know what to do don't bother getting an emulator like even g or gns3 or cml or anything else that's going to take a lot of time to learn because what you want to do now is focus your attention on learning the technologies which you can do for free with cisco's packet tracer so i really i almost want to hear nothing at the ccna level about doing anything except for packet tracer and that's why i have at the keithbarker.com i've got 20 or 30 labs and jeremy's jeremy's labs jeremy's it labs jeremy's if you google uh jeremy jeremy's it labs on youtube he has got a boatload of free labs as well david bomble has a bunch of free labs and also i think he has some other paid options as well so just just focus on practicing and making using the most the best solution that's most elegant and the most the best solution is most elegant for getting the hands-on practice that we need is packet tracer for free because once you start getting a genus three and even g and cml it becomes an issue of how am i smart enough to get this all working right now and maybe you are but possibly you don't have all the time in the world to do it and so my my coaching would be ccna level stick with packet tracer trust me on this save yourself hours and hours of frustration and time and then after ccna you want to move on to other technologies and like professional level and other vendors then let's look into other emulators such as evg which is my go-to favorite these days all right but i have licenses for cml cisco modeling labs i've got a license for even gpro and uh i haven't touched uh gns3 in a few and a few years because i use the other tools all right moving on here we go uh bra oh epic glider glides in the first place congrats all right here's question number eight which type or what type of virtual ip address is provided by a first hop redundancy protocol where is it first top router protocol let me look that up [Music] it is first top redundancy protocol so it's hot standby router protocol but the actual category is first hop redundancy protocol or if you stick with the acronyms you're good either way [Music] wow i got a whole bunch of multicast that's super let's take a look i'm always uh i'm always pleased when there's some diversity there as far as answers um this ip address right here let's see where is it uh all right here the virtual ip address being provided is 252 2 100. that my friends is a unicast address an example of unicast addresses would be anything in the class a b or c ranges which is you know like one dot anything up to two 23 that'd be the highest end and then a multicast and ipv4 would be like 224.x and a broadcast looks like this 255 255 255 etc so a broadcast at layer 3 equates to a broadcast layer 2 which is 48 bits on ethernet and that would be all that all the bits would be on there too that would be a bunch of f's so long story short the virtual ip address provided by first top redundancy protocol is a unicast virtual address that clients are then going to likely use as a default gateway to provide that fault tolerance in case one router goes down the other one can take over the work all right next question epic lighters first place here's question number nine which of the following is an hsrp virtual mac address for group 10. [Music] i'm going to give you a huge clue here if you'd like it and you get people who can answer that right right out of the gate a chance to answer it for everybody else look at the last character the last character is going to be hexadecimal representation of the decimal group number so what is 10 decimal 10 in hex and that's the answer you're looking for last character [Music] so [Music] all right nice work and uh fernando congratulations on passing your ccna uh so pleased to hear that and uh makes my makes my day really does i appreciate all the effort really i think for me putting in the effort and measuring that is almost as important as you know the final goal because if we put enough effort we get one percent better just a little bit better keep on pushing forward forward forward and we keep that consistently we're going to end up in a better place and congratulations on reaching that goal that's great so 65 of you nailed it fantastic here we go next question 10 of 15 multiple select which type of hyper hyper hypervisor runs directly on hardware [Music] [Music] [Music] all right fantastic there was a question in the queue i meant to answer a few moments ago asking should a person after ccna should they go for ccnp or say go for devnet first what should they do it really depends on what you i i would personally recommend after the ccna go get your ccnp that really separates that individual from the herd also you're going to learn a ton and then after you know more about the professional level with networking including some virtualization in that world then if you want to automate some of that then dig into the automation tools like ansible and other apis and how those work but you know it depends on if you're going to need them or not my son is a programmer and he he lives he lives for apis it's all he does interacting with systems using software that's calling on apis that's all he does for a living and he knows very little about networking and me on the other hand i know quite a bit about networking and very little about apis and normally in a company especially a large company there's going to be people who focus and are bet are really good great at one or the other so i don't know if somebody could be really great at both maybe knox hutchinson if you're not following knox sections and follow him he is amazing and he's really good at both all right uh so what type of hypervise let's talk about first of all what exactly is a hypervisor let's imagine let me clear that off let me start better let's start with this let's imagine this is a physical computer p h y s i c a l alright and so sometimes this is called a host this host has cpu it's got some memory it's got some storage and maybe it has that storage is directly attached or it's network attached or whatever but it's got those resources and so on that hardware what we do then is we run or one option is to run a hypervisor right here h-h-y-p-e-r-v-i-s-o-r so we run a hypervisor and then a hypervisor is like a an environment where virtual machines can be created and run and so on that hypervisor which is running on the hardware it supports virtual machines so each of these blue rectangles represent vms and each of those vms are going to have a guest operating system let's imagine that this one is running windows server and this guy is a terrible color that's all right uh and one is running like linux and whatever you want to run on there so they're running a guest os and then the applications as well that are on that those applications could be virtually anything and so that's example of a type 1 hypervisor which is a hypervisor that runs directly on the hardware so one example of a hypervisor that runs directly in the hardware that many companies have on-prem would be something like this this is an example of here's our host that's our physical hardware this is running esxi from vmware just and in the cloud amazon web services have their own hypervisor functionality uh google cloud has their own hypervisor services microsoft azure has their own flavor of hypervisor but the concept is the hypervisor that runs directly on the hardware and then provides the environment for the vm so over here on this current esxi host which is running vmware esxi uh it's got this virtual machine which is currently running and it's got even g pro that's where uh the funny thing is to me is that this little vm right here that we're demoing on this vm so it's nested so we have the physical host running the esxi hypervisor which is running these two vms and then within this vm which is evgpro it's running a whole network environment including additional virtual machines and it's using a technology in this example to do that called containerization and this is an example of a docker container inside that virtual machine that's actually providing this little emulated pc that we've been playing with it's also providing uh all this as well so everything you see here including this little virtual machine that's all running in a virtual machine that's all running on this hypervisor in iraq right behind me okay so that's fun and let's go back here and uh also refer to as a bear metal hypervisor a type 2 hypervisor just to close out that conversation would be like this so here's our hardware sometimes i like to call that a host and on that host we instead of running a hypervisor directly in the hardware we run an operating system like mac os or like windows or like linux and then inside of that operating system we run an application like you know lots like word processing spreadsheet games whatever but one of those applications that we can run is referred to as a type 2 hypervisor so a type 2 hypervisor runs as an application as on a machine that has its own operating system then we have virtual machines that can be created in that space so examples of this would be virtual box and also a vmware workstation they have a program you can buy that runs on top of the os and still allows you to create vms but you have the osb underneath it all supporting the physical hardware okay so type 1 over here on the right bare metal hypervisor type 2 over here running on top of some type of os not directly on the hardware great work here we go moving on epic glider is still staying in first place nimble raven bronze crab joyful cat mirror mirror and balanced panda all right here's question 11. who could provide an hsrp virtual ip as a gateway for the pc up in the upper right hand corner right here looking for one answer [Music] so [Music] all right i had somebody ask about my son's youtube channel he is uh one of the most amazing programmers and developers i've ever met he is uh not quite 30 i think he's approaching 30. and let me grab that link real quick and he makes videos uh for he's an incredible musician too his brain just works on all firing on all cylinders let me go ahead and post that link if you have any interest in that too in the chats paste and there it is pollyanno uh let me give you a little video or a little preview of that looks like this it's really quite amazing his videos he he has a i think it's like a a raspberry pi that he is programmed to light up the keys as they're played and then in post edit he adds on the additional uh flavor the additional fun and uh let's take a look at how he's doing how is he doing he's doing pretty good so we go to videos and we go to wow look at that one that one has 188 000 views all eyes on me wow anyway i'm so proud of all my kids i've got seven kids and they are all my favorites yes i tell each one of them when i'm with them privately you're my favorite they're all great no doubt okay so and for this question who can provide an hsrp virtual ip address any layer 3 interface on a router or multiplayer switch could be an hsrp active device so for this pc that could be this layer three switch here multiplayer switch or because it's a trunk a layer two trunk it could also be switched to so that's what i'm looking for switch to our switch three as the correct answer also right after this i am i've got a few minutes i would love to hang out in the discord server so if you have questions about any of these questions or want some clarification come join me just afterwards in the discord server all of it's free and i'd be happy to chat with you we'll just hang out in the ccna chatroom and take your questions if you have them all right here's question 12 of 15 with hot standby router route hot standby router protocol which ip address is used for the client default gateway oh my gosh uh there's a lot of hsrp in this quiz so i put these together last night actually yesterday afternoon and i may have been a little bit heavy on hsrp but there's probably a good reason for that [Music] all right nice work also brandon congratulations on your job and as a knock engineer and also thanks for the kind feedback on passing the season a uh i'm so pleased onward and upward for all of us and yeah the virtual ip address is used as a client default gateway and that's why hsrp is there all right question 13 we're nearing the end how do you see the virtual ip address oh my gosh more hsrp um [Laughter] so if you're not yet studied on hsrp my apologies but it is definitely one you want to be aware of for ccna although the blueprint says describe the purpose of a first hop redundancy protocol i would encourage you to do a couple of my labs and take it to the next step just practice it [Music] so [Music] all right now if you've been with me uh in the office hours and you've been with me on my live streams and such and you know that i don't have every single command memorized but i do have a very good general understanding of how the protocols work and also how to use context-sensitive help so it isn't as critical like two decades ago [Laughter] or even a decade ago with the old ccna it was like okay do you memorize all these commands exactly the commands and now it's more of do you really understand how it works uh and so it's it's it feels a lot less like a memorization of what is the exact syntax but something like this if somebody has lab this up a few times you know you're gonna remember show standby because you've done it and so maybe the first time you practice with it it's like what's the command to see the standby information and then you look it up or you do a question mark it you see it and you do it a couple more times it's going to come in helpful now let me share with you the reality of this knowing how these protocols work it's gonna be super helpful when in a production environment you have to solve a problem something's not working like it should well how's it normally supposed to be what's different what changed and so all this is leading to enhanced skills that people will pay you for because you have a job that needs them and and am i going to be am i going to have a job keith that has all six domains of the ccna that i need to know all the time no but by george you're going to have two or three that are used all the time like routing and switching very likely in the networking world and ip services and security all the time all day all night you might not have to cable networks you know we might not have to you may not have to implement a three-tier hierarchy or do a spine leaf architecture because it's already in place but most of the other stuff is very very useful on a week by week by week basis all right so she'll stand by nice okay i think we're rounding the corner here's question number 14 what is true my friends regarding a functioning hsrp group with these routers three routers to be specific [Music] [Applause] [Music] uh [Music] dan i agree this is worded this is a tricky wording here [Music] all right so i i agree this is a little bit tricky but here we go so if we have a network segment right there that's how an old person draws a network segment and then then you have i'll just draw one pc right there pc representing any networking device as network interface card that's going to be on the networks this could be a printer it could be a mobile device whatever well in this case it's wired but the same concept would be for wireless as well then we have three routers we have one two and three and they're all part of the same hsrp group and the virtual ip address let's say it's 10.9.8.67 and so we have a dhcp server somewhere or a dhcp relay either way that's handing out ip addresses to clients in addition to sending out the default gateway it's going to hand out that ip address so which of these three should actually respond to ip addresses like doing arp response and so forth regarding this ip address so the pc does an arp request say hey this is my default gateway i need your layer 2 address so i can forward a frame it is an arp request it's a broadcast they all see it who responds so as far as support i agree tricky word but only the active hsrp router is going to support or answer that call for the layer to address so let's say r1 is active so r1 would respond to that arp and would respond with the virtual mac address associated with that virtual ip address and then if router 2 is the standby great and then if radar 3 is neither he's just waiting in the wings for somebody to fail so if the active goes away or fails loses the link then router two would go active and then three which wasn't even active or standby it would then go standby so with hsrp there's exactly one and only one active router for a given subnet at any time and then there's only one standby at any time and if you have more than that in a group for the same exact subnet uh they're just waiting in the wings in the event they need to get called on to step in and become standby and or active if there's a catastrophic failure most of the time you're not going to have more than two okay all right monica welcome welcome and i think we have one more question awesome shark nimble raven epic glider daring lobster and joyful cat wow all right here it is last question what is a hypervisor the faster you answer correctly the more points you get go go [Music] [Applause] [Music] all right look at that amazing no no no comment required on that except for way to go let's look at the podium congrats everybody thanks for being here [Music] [Applause] [Music] [Applause] drum roll please [Music] [Applause] and that's why the shark is awesome nice work let me get a little bit of feedback but here's our toughest questions out of all those questions which i think was like 15. um these are the three toughest uh that were answered 11 percent correct 19 correct and 22 correct and uh not bad especially this one is like wow all these things in the apology i only have like 90 seconds to think about it so that that's a given that's a good push that one don't feel bad about that if you didn't get that right so here's what i'd love to do let me get some feedback from you and also i i'm going to hang out in the discord server for a few moments let me i'll post the link there in the chat in a few seconds there's also a link in the description we'll be in the ccna voice room i'll leave my quiz engine open if you have questions on that i want to congratulate everybody who's taking effort and spending time and effort on studying and getting better i always i've told people and i believed it and i've experienced in my own life the better your knowledge and skills regarding networking and i t the better your quality of life can be as a result and it doesn't matter where you're starting you can improve and get better it's just a consistent effort enjoy it too have fun along the way but we can just consistently get a little bit better and a little bit better and eventually have uh success and then just keep on moving it forward so life isn't fair never will be for anyone some people are have less advantage than others and my goal is to help everybody who wants it to help them improve just a little bit make a small difference and uh improve their situation all right thanks everybody i'm going to go ahead and give you some sign off music and i'll post that link here in a moment for the discord server and i'll be in the discord in the voice chat room i would just ask if you join us if you're not going to be chatting just mute your mic and if you want to chat just unmute it and have at it alright everybody thank you very much also a heads up and a thank you for dan for next saturday who's going to be moderating the office hour for me i've got another commitment that's going to have me in an airplane at that point in time otherwise i'd be there but we'll also have another quiz on sunday so schedule schedule 10 o'clock saturday pacific time and 11 o'clock sunday pacific time and let's enjoy this time together alright thanks everybody see you in discord or in the next live event bye for now [Music] [Music] [Music] [Music] [Music] [Music] [Music] you
