If I were to do the CCNA composite exam how much trivial memorization should I expect to need to do.

I failed the part 2 twice before I said "Why am I putting myself through this bullshit?" Then again, I never, ever touch a Cisco router in my day job, so it was more of a "this will look good on my resume" thing than a "this is necessary for advancement" thing. Spend lots of time on OSPF, EIGRP, (R)STP and archaic WAN links.

Some basic port numbers, link costs for certain protocols, maybe IPv6 group addresses (though I only ever saw those in like, one practice test), but it's mostly conceptual.

I guess it depends on what you consider "memorization." If you're worried about memorizing every port number ever, don't be. But you sure as poo poo better know the order of steps for selecting a spanning tree root switch (and the differences in names between STP and RSTP. Because they change, for some bullshit reason).

I can do multi area OSPF, can subnet perfectly, layer 3 etherchannel, vlans. I was just concerned about poo poo like what is the default value for the 3rd K value in the eigrp routing algorithm or expect me to know that eigrp's AD is 90, OSPF is 110 or eigrp's protocol number.

You need to know the cost of all the routing protocols, yes. You also need to know costs of different links for STP. Basically just cram STP and routing over and over again, because that was like half the test (Oh God, it's coming back to me. I think I have PTSD). The other half is going to be "What's wrong with the configuration on R2?" KillHour fucked around with this message at 19:51 on Mar 20, 2015 |

There is some random incidental stuff like that- EIGRP being 90 versus OSPF being AD 110 gets brought up (I remembered that by reasoning that EIGRP is Cisco's protocol, so Cisco devices would prioritize it. no idea if that's actually the rationale, but it helped me remember). But yeah, it does depend on your definition of "memorization", I guess. Like, there isn't any "memorize this table of things and numbers that any sane engineer would just look up anyway" like there are on the A+. But, for example, knowing that the command to see what type of devices (switches or routers) your neighbors are is show cdp neighbors is absolutely something you should know without googling.

You need to know configuration commands front to back, because they will ask you to do bullshit like know the syntax for a given command is slightly wrong. That's what got me, because I really don't use this stuff enough to bother memorizing any of it (and I've forgotten 90% of what I learned studying).

I should be okay then because I've done ridiculously elaborate work in packet tracer and real hardware for actual configuration. For the spanning tree bit is it just know that it sucks and that you should always use (802.1W) rpvst. Root bridge is determined by lowest mac by default, you can specify a certain device you want to be root, you can set different roots for different vlans as a load balancing measure, secondary bridges for backup. Then know the two different commands for actually doing it? I'm just not sure of the scale, depth or finickiness of the exam because I've never wrote a vendor exam before. Alright I can figure out which links would be blocking too. How is the exam administered then, do they sit me down infront of a program simulating a network with a list of things to do or is it paper based?

Methanar posted:I should be okay then because I've done ridiculously elaborate work in packet tracer and real hardware for actual configuration. They will go deeper than that. They'll ask you to say which link in a network actually ends up being disabled (and on which side the disabled port is). You actually have to follow the logical steps (R)STP takes and draw it out to find the answer. They'll also ask questions on specific versions of protocols you WON'T ever use (like know the differences between STP, RSTP, PVST+ and RPVST because they'll pick one at random). Mostly because they're dicks. Edit: In fact, just assume they're going to be dicks and do things like set two switches to the same priority in a map of like 7 switches. Double Edit: Had to clean that up. I'm rusty.

I just finished a 7 day bootcamp of 8+hour days in class followed by 3-4 hours of cram sesh every night. But now I have my CCNA and CCNA: Sec!  I did the ICND1/2 path, and I have to say I could have probably made it through ICND1 without the class. ICND2 and the security stuff though, it was super helpful to have a teacher who knew how to distill down to what the exam wants you to know. I wouldn't call myself an expert in any of those topics but I definitely have some foundation to build on now.

Im studying for ICND2 now, right now at VPNs and GRE in Odom's book. Any thing jump out at you that should be hit hard? I hear everyone says RSTP.... Someone over at reddit.com/r/ccna stated that Odom had an addendum on STP stuff too http://ptgmedia.pearsoncmg.com/imprint_downloads/cisco/bookreg/9781587143731/40_9781587143731_appb.pdf

The questions aren't verbatim all the time but you'll definitely recognize some of the diagrams. Also make sure you know your PPP, frame-relay and know a bit about ACLS (mainly the types/differences between named, standard, extended and dynamic, and how the configurations work with wildcard masks).

I think ICND2 is where you start to get into LSA types/propagation, too, which does require some memorization.

Question: I passed the A+ 801exam last august. Since then I've been loafing around and putting off studying for the 802, and keep rescheduling it further and further away. Is there a time period in which the 801 would expire and I would have to take both again? I'm going to buckle down and get the 802 done this spring, I just want to make sure its not too late.

Spudalicious posted:<redacted> was a great resource for me for some of the simulation questions: URL changed to explanation about dumps The questions aren't verbatim all the time but you'll definitely recognize some of the diagrams. Braindumps are considered cheating here. If you already know the questions to the test going in, you are not tested on the knowledge in the field, you are only tested on the specific wording of that question. Also: if Cisco ever finds out, your CCNA will be voided plus you will get a ban from testing with Cisco again.

Then know the two different commands for actually doing it? I'm just not sure of the scale, depth or finickiness of the exam because I've never wrote a vendor exam before. The exams are computer based. Cisco actually has the exact tutorial you get before every test online, so familiarize yourself with that. One point of note for Cisco exams, that is different from most other vendors' exams: there is no back button. Be especially weary of the for multipart questions, where you will have to answer all questions before hitting next. e: The tutorial and the EULA don't count towards your time. Take this time to get yourself comfortable before you get going. You can also use this time to jot down some references, so you don't have to think about it during the test itself. As to the knowledge level needed for CCNA: The hard part about the details you need to know, is that the level of explanation now is so shallow, you won't be getting the why behind the values. The why makes it a lot easier, but also require a lot more info to work with. As for spanning-tree: Draw some random diagrams of switches and links, pick random port speeds between them and give every switch a random priority and mac*. Now go through and if you can answer which ports get which role, you know enough for the exam. Make sure to mix link speeds to make everything more difficult though. You dont have to go for the full 32 bit priority or 48 bit MAC address. If you just give them Prio "8", Mac: "1a", it will not change anything for the logic and calculations.

Yeah, you just have to pass DESGN. You have to know a little bit less about R&S than would be required to pass ICND2, but you also have to know some extra stuff about collaboration, security, etc. It IS still just an associate-level cert, but it's not the easiest one of that class that Cisco has.

The second he goes in there with his VCA, he's going to get asked to provide costs. And get asked technical questions. The first set of which will cause jaws to drop if it's coming from Joe Helpdesk, the latter of which don't get taught until the VCP. Your co-worker will score a real coup if he goes for the VCP. He should get on the Stanly waiting list and take the required course for $125, and then he'll come in with some actually usable knowledge. If he takes and passes the VCP, he can come in with a hugely recognized industry-standard vendor cert and the knowledge to back it up. I mean, you could always open up a VMware account under a work email, register some interest in vSphere, and talk to a sales rep. Maybe they could give a voucher or a discount or something, doubly so if your co-worker presents himself as wanting to take some responsibility and be that sales rep's leverage into your organization.

Sometimes it's "here's a link to the exam blueprint, and here's a link to VMware pubs, good day", nothing more is asked of you. In my second post about it I pitched a possibility of getting a discount or voucher by signing up for a VMware account (which is free) and talking to a rep about a voucher for the VCA (asking is free). Maybe if he talks to the Powers that Be about it, they might agree to reimburse exam costs if he passes and provides proof. Which shouldn't be hard, because unless they changed stuff around, you take the VCA online and could probably open-book it. But KillHour sums up the example entirely correctly. I know what you're saying with the "just answer the dude's question, why you gotta be goons and pitch an answer in the entire other direction" but the VCA is a literal waste of time and money if it's not reimbursed. Its contributions won't allow him to take on building even the simplest VMware solution - it's literally designed to get people to talk up how great the cloud is and how awesome VMware is for anything related to the cloud. I'm willing to bet that if a proper survey was done with statistical controls and everything, between people who have the VCA and people who don't, the amount of benefit having the VCA has done will be little more than a rounding error. If he's taking the VCA out of his own pocket, the only thing I can think of is asking a rep for a voucher in exchange for talking up VMware, which is what the VCA is out to do. Some googling yielded this page; if there's a deal from VMware this is where it'd be: http://mylearn.vmware.com/mgrReg/plan.cfm?plan=41387

Now that I got my VCP. I've been looking at the next certification to work on and have been fairly interested in linux as of late. So i'm looking into the RHCSA and I read somewhere on here that a new Jang RHCSA book is coming out sometime soon. Are there any other resources that are good so I can at least get a jump on the material? Would the REHL 6 deployment guide suffice or is there something better?

The Red Hat certs are in a terrible spot right now. The exams are updated for RHEL 7 but none of the popular books (maybe none at all?) have been updated to match. Jang's isn't due out til this fall. RHEL 7 is a pretty big departure from 6 in a number of ways, such as systemd vs SysV init and firewalld vs iptables, so if you aren't using it frequently at work it could suck trying to squeak by on outdated materials.
