MrBigglesworth posted:What is the exact logic of locking out some functionality that every router/switch on the test, that in the real would would have available to you? I think part of it is that it's probably easier for them to create the sim questions by limiting the command list. If you're taking the ICND1 really just have a good knowledge of the show commands for the most part to get the info that the test is asking for.

When I was taking ICND1/2 this year, the only thing that I remember being locked out was pipe (which would have made some long show commands easier to use). ? worked.

Im just getting really nervous as I have been on an off of studies for CCNA for 13 years, with only REALLY getting into it since last November and finally getting a job in networking. I did hell desk for 11 of those years, with only looking at Cisco stuff from a distance and never really taking that first step since exposure to it in 2001ish. I got my Security+ in April, failed of the MCSA 2008 tests because MSFT tests can suck a bag of rancid dicks.

The ICND 1 test consists of subnetting, subnetting, remote access, subnetting, protocols, MAC address tables, switch port security, subnetting, ospf, and subnetting. e: also subnetting.

Its been a while since I did ICND1 (so long that it's expired) but I think there's some browser access in there too so have knowledge of how to enable http access and know your way around the SDM (i think that's what it's called)

Completed the last CEUs on Skillsoft to renew my Security+ CE today. Pain in the rear end, but cheaper than retaking the exam all together. I was able to test out of like 80% of them, which certainly helped.

Well I got a 933/1000 on ICND1. It really wasn't so bad. There were multiple questions about what a switch would do when it received a frame with a MAC address it didn't know. Also their simulator is complete dogshit compared to the sims that the Pearson Network Simulator study materials had.

If a switch gets a frame with a mac it doesn't know it floods all ports (except the one it came in on) with a broadcast to FF FF FF FF FF FF to ARP the MAC. Congrats, I take mine in 40 minutes. MrBigglesworth fucked around with this message at 20:30 on Jul 11, 2014 |

Well, you passed, but this is incorrect. I have my 100-101 scheduled for the 16th, but I may push it a week because of procrastination/crappy work schedule this week. For some reason I've been avoiding certs even though I've been working with this stuff for a while and know a lot of it. It's not even it being a test that bothers me, I never had test anxiety in school. I wanted to just take it because I feel once I take one test, I'll be over the initial hurdle and will be OK taking more.

the real blah posted:Well, you passed, but this is incorrect. How is that incorrect? If a frame comes in, the switch will record the mac of whatever sent the frame, if it isnt already in the mac table. (If the MAC was already there, it just then forwards to that MAC) It then looks at the rest of the table and does a lookup to see if it already knows about the destination MAC if it isn't there, then it sends a flood broadcast to all other active switch ports to see who responds to the ARP request and the MAC will be recorded in the table for quicker lookup before it clears out after a set time. A resource on the network that says, hey I have this IP, it then responds to the request, the switch records who responded, all other devices discard the frame because the request wasn't for them.

A resource on the network that says, hey I have this IP, it then responds to the request, the switch records who responded, all other devices discard the frame because the request wasn't for them. A switch will never send out an ARP. Switches are layer 2 and don't look at IP addresses. For a source MAC it doesn't know, it'll record it in its table. for a destination MAC it doesn't know, it will forward it as is (it won't change to the broadcast ff-ff-ff-ff-ff-ff) out all ports except the one it received it on. It's the Layer 3 device's (router, client, etc.) responsibility to perform an ARP when it doesn't know what MAC address it should associate with a given IP. Someone please, please correct me if I am wrong. Edit: To clarify, a pure L2 switch. It'll arp from a vlan interface when communicating from that interface(which has an ip and is layer 3,) but not when it's just receiving and passing frames as a switch. the real blah fucked around with this message at 06:51 on Jul 13, 2014 |

If the switch changed the destination MAC to broadcast then all recipient ports would accept the frame, which is the opposite of what you want to happen.

Probably beating a dead horse at this point but don't confuse the ARP table with the ethernet forwarding table/CAM table/MAC table. While a switch can learn about where things are based on things like ARP requests it won't necessarily add these ARP entries itself. Here's an example of an ARP table off one of my lab switches: code:
Here's the MAC table: code:
As pointed out, unknown unicast will get flooded to all ports except the source port but it won't change the destination address to ffff.ffff.ffff.

A more casual way to put it is that it would be silly for a switch to go all "hey whose Mac is this" to everybody only to wait for a response then say "oh OK well I have this for you* when it can just say " hey if this is you I have this for you" to everybody. You cut out two unneeded packets this way. Does anybody have any ICND1 refresher recommendations? I've taken quite a few classes in the last two years that I feel like getting the books in the OP would be overkill but I don't feel confident enough to just blindly take the test without reviewing.

Thirteenth Step posted:Whats everyone's strategy for exam revision? I just looked at a video course provided by my employer and it was garbage. I took a practice exam and almost every question was something that wasn't covered (completely) in the video series. The videos were from PlauralSight which I think used to be TrainSignal but i'm not sure. Don't bother too much with videos if you already know the material to a degree. Videos are great for a high-level overview for people who are just getting familiar with the material, and they do contain some good info, but I found that most video series are just there so people won't be all "what the gently caress is this??" when they pick up an actual Cisco Press or Lammle book. They're great for a 10,000ft overview, but for specifics and scenarios you're not going to beat printed material and lab exercises. So IMHO the best exam revision strategy is sim sim sim. Find a well recommended lab book for your subject of choice and glue yourself to the appropriate simulator/emulator/platform.

So a question on Cisco career specialization paths.... I now have my INCD1, getting ready to start studying for INCD2 I have always wanted to get my CCNA and them move into CCNP R&S. Looking at the certs there are specialist side tracks in Voice, Security, Data Center and a few others. Things we do where I work strongly lie along the path of Data Center. I am wondering, the best path to take the Data Center track, it appears CCNP Data Center requires CCNA Data Center as a prereq. Should it be CCNA R&S>CCNA Data Center>CCNP R&S>CCNP Data Center or CCNA R&S>CCNP R&S>CCNA Data Center>CCNP Data Center Wondering what would be the more beneficial/natural path for building one on top of the other.

CCNA Datacenter covers a lot of similar basic networking that the R+S does but doesn't deal as much with things like WAN connectivity. The Datacenter track also covers a little bit of storage networking and UCS as well. Also I did a thing Friday: So pretty jazzed about that.

# ? Jul 14, 2014 19:13 |

Data Center doesn't use ICND1 as a prerequisite. Since you already took it, might as well finish and get a CCNA cert like R&S since it's only one exam. I'm along the same path as you, and after thinking it over I'm going R&S to VCP to CCNADC.

The first CCNA DC test is basically a one test version of the CCNA R&S with the focus on NX-OS instead of IOS. The material is very similar but covered at slightly less depth. The second CCNA DC will all be distinct from the CCNA R&S. It focuses on Cisco's DC hardware portfolio and basic verification of configuration on things like UCS, FEX, 1KV, etc....it's harder to study for since there isn't much in the way of lab equipment to simulate that stuff, but the test also doesn't have too many sim questions. It does have a fair number of product specific questions such as "how many 1GbE ports are on X model switch" or "which FEX models support Y feature." Since you're already doing the R&S path you might as well finish that, and then do CCNA DC and CCNP DC, if that's where you ultimately want to end up. However if you aren't working in a very Cisco heavy datacenter and spending a lot of time with UCS, Nexus, and 1KV then you're going to have a really hard time passing the CCNP DC.
