Ok, So most of you that are reading this have been helping me for the past..oh i don't know..a long time. I am going in for my CCENT Wednesday. I don't know why but i feel as if I'm under prepared. So far this is what I know

1 - OSI Layers and what they do
2 - Basic switch commands
3 - Subnetting
4 - Basic router commands

With A+ and NET+ i just studied for a few days and took the test din't think twice about it. But with this I feel like it's pass or die. I'm sure that some of you have been there. So my question is are those pretty much the 4 things that you need to know to pass the CCENT. Once i pass this (i don't care how many times i have to take it, i'm passing) ill be looking to take the ICND2 test and from there hitup security....baby steps but this is my first step in the pool and i just don't want to walk into the testing and wig out because i don't notice something on the test and spend all of my time on something i didn't study.
 
Just watch your time, and concentrate on those subnetting shortcuts. Don't freak out on the sims, and don't get discouraged if you don't pass the first or even the second time!
TIME IS VERY IMPORTANT!

What I like to do in the last week before the exam is take the exam blueprint and use as a check list. Go right through it and either check off the topics you feel very confident about and then focus on the weaker areas.

I also, used to take some of my notes to the exam center with me and use for some last minute review before going in.

Good luck.
 
Remember that the sh run will most likely be disabled.. Know your show commands.. especially for the Sims..

sh ip route
sh version
sh cdp neighbors
sh cdp neighbors detail
sh controllers
sh interfaces
sh ip interface brief
sh ip interface <interface>
sh vlan
sh vtp
sh interfaces switchport

Any others I am missing on the CCNA level guys?

Also, ACL's are part of the ICND1 and have been referred to as the most "difficult" topic on the exam.. You should be able to look at a an ACL and readily identify an issue with that ACL. Fluent yourself with standard and extended ACL's.. both numbered and named.

I have a friend that failed the CCENT once and then passed. He took the Network Academy course with me and it was the old course. I believe that the wireless and security questions got him. You can download the SDM demo as well and that would be a good idea...

SDM
Cool link:
Good article:
Download the sales demo here:

Also read the first comment after this article o Wendel's blog.. That is pretty much dead on for study technique...

I also recommend a Red Bull just before taking the exam.. Helps with concentration...

You have the OSI layers down.. Just remember what layer does what...

IE. You are network admin for your company. There was a reported issue on the network and users can not connect etc etc. Ypou are now logged in via console to one of the two routers your company controls and can not ping between the two. A show cdp neighbors is also unsucessful. Upon running a show controllers command you realize that there is an excessive number of collisions. At what layer of the OSI model is the problem occurring?

When i think of collisons the first thing that pops in my head is a hub. I would say that the collisions is at a layer 2 (data layer).
 
Collisions occur at the physical layer.. Layer 1.. Incidentally, a hub is a layer 1 device... Switch = layer 2, router/L3 switch = 3.

SDM - I have a 2611 Router that i just configed. I am about to install it (if i can) it's SDM 2.4 If i can't load it then ill be a demo SDM user!


I kinda figured that sh all would be disabled. So far what I have learned on the switches and routers is the standard setup procedure and locking down the device.

no
en
conf t
line con 0
password cisco
exec timeout 30
exit
line vty 0 4
password cisco
exec timeout 30
exit
do enable secret cisco
end
wr mem


This procedure is locked into my head. It's not the best start but it could be worse..it think.

I have a cisco PIX501 at the house that i use to forward ports over and what not. That has helped me learn a bit about the ACL's. I really don't know why you need standard and extended one yet..I'm going to hitup the chapters on that tonight. My subnetting is somewhat of a mix of a cow and a mcdonalds...someone is going to die. So i need to get better at that. All in all i could hack my way through a network setup with a few routers in the real world. put in a pix, setup a vpn connection, setup open ports. setup a few vlans. But i have been coasting on that and really need to learn the right way on everything....So thanks to everyone that is helping and if i could give more than just Stars to people i would!
 
In the example above where you have an excessive amount of collisions that would be indicative of bad cabling or possibly the NICs. Could also be that you are running half duplex and CSMA/CD is active. Could also be that you have a hub(s) that could be replaced with switches in order to reduce collisions. Regardless, you would begin troubleshooting the physical layer at that point.

I am kind of breaking the direction of this thread but I will post a little more about the OSI layers.

Layer 1 = Cables, Hubs, Collisions, Bits
Layer 2 = Ethernet, Switches, Frames
Layer 3 = Routed Protocols (IP, IPX), Routers, Packets
Layer 4 = TCP, RTP, Routing Protocols (RIP, OSPF), segments
Layer 5 = Session think ESTABLISH/TERMINATE connections, data
Layer 6 = Presentation think ENCRYPTION/FORMATTING, data
Layer 7 = Applications, HTTP, SMTP, telnet, FTP etc., data

ok.. Now back to subnetting... Sorry guys..
