what is a mac? error dectection. responsible for framing and media access

how do we deny telnet traffic from on s0?

what does a manual shutdown look like when you run "show s1 status"?

with an ip address and access list, how do you display what interface a list has set?

what specifies a second sub-interface on s0?

how do you define an interface on a cisco 7000 or 7500 with a vip card installed?

what are the components of the route command?

which class allows for the fewest hosts?

what does the mac layer of the datalink layer do?

something about serial communications with a permanent virtual circuit with layer 2 id s (can t read my handwriting on this one, sorry!)



the bottom line? know the osi model *very* well, and know the basic commands on a cisco router and you should do fine!

good luck!!!

p.s. test #1 and test #2 were eerily similar... there must not be a huge pool of questions... ;)


odds and ends i have found so far....

>the ccna test is 70 questions, 68% to pass.

>concentrate on the osi layers and

>tcpip addressing.

>forget about appletalk.

--------------------------------------------

a couple of topics seem to be reapering in the test

1) osi layers and where the protocols fit in.

2)tcp/ip and ipx/spx

3)configuration commands and there syntaxes

4)access lists and there syntaxes.

5)isdn, x.25,

any demo tests you do you would be looking to score 95-100% on and even then it s ?. i m not looking to scare you but it wasn t easy, and if you have the cisco icrc router config study guide it helps. goodluck.

--------------------------------------------

: osi layers.

: read the icrc material (either take the

: course or read the icrc book.

: subnets

: - no appletalk -

--------------------------------------------

what is actually on the test?

according to cisco you need to be able to configure and manage "simple" networks. what defines "simple" networks (according to cisco): ip, igrp, ipx, serial, appletalk, frame relay, ip rip, vlans, ipx rip, ethernet, access lists in addition to the recommended study topics you should be very fluent with several other (not all listed) topics. a few examples of these would be: the osi model, and cisco discovery protocol. a lot of the questions deal specifically with the cisco ios, such as installing, logging in, navigating, backing up, and debugging.

--------------------------------------------

i am compiling a list of urls that are of use to those seeking cisco accreditation in the routing and switching field. the list has thirty entries so far and can be found in the networking resources section of my home page at:

--------------------------------------------

: there is an extensive demo exam for ccna on the syngress web site. about 215 questions. i was wondering if anyone could tell me how close these questions compare w/ the actual test. i am at about chapter 7 in the study guide and am open to any study groups that anyone is trying to organize.

i have taken the ccna test a couple of times and there seems to be a couple of questions that showed up each time that i am curious about.

1. what is the command to show you both source and destination dlci s in one command. i m thinking it is show frame-relay route but i m not sure.
