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.
2. What is the command to show both source and destination addresses in ipx. I'm thinking it is "debug ipx activity".
3. What is half duplex? I know it is you can tx & rx in both directions but only one at a time, but the way they word it is confusing. They say it is transmit connected to receive circuit or vice-versa or they say it is like a one way bridge. The closest answer I could find in the multiple choice it the one way bridge?
-------------------------------------------------------------------
Took the test for the first time and the syngress book covers about 60 to 70% of the test. There are ?'s on banners and the IOS commands to set it up. Know OSI and what each layer does. Know IP and IPX configuration commands. Know Access List, the IOS commands to set them up, and how to interpret access list. Understand how to use TFTP, flash, etc. to config router image. I got a 44% ,but this is my lucky month so look for more post.:)

test name: CCNA (Cisco Certified Network Associate)
test # 640-407

Braindump for CCNA 1.0 (640-407) Exam
I took the exam on Nov. 25, 98. The exam is 90 minutes with 70 questions.
The passing score is 68%. Just managed to pass the exam at 72%. Overall, the
exam is fairy tough, especially for those don't have hands-on experience on
routers.
Resources that I used to prepare for the exam:
1. ForeFront CBT. (It is pretty good except it misses some subjects, such as LAN switching, VLAN, fast Ethernet, etc.)
2. Syngress CCNA simulation exam. (Not too good, as it has lots of errors, and the exam format doesn't match the really one. I double if there is no good simulation exam in the market)
3. Syngress CCNA book.
I would recommend that people should have hands-on in the Cisco routers with at

lease IOS 10.x before taking the exam, as just memorizing the command syntax and parameters wouldn't be easy to pass the exam.

1. About 10 questions in the description of the 7 layers of the OSI, also with respect to how they match the layers in TCP/IP, Frame-relay, ISDN BRI, etc.
2. Which of the following three in the "Presentation Layer"
a. PICT and JPEG
b. MIDI and MPEG
c. NetBIOS and RPC
d. NFS/SQL
e. ASCII &
3. What is the correct description of MAC address?
4. Which of the following methods are used as flow control?
a. Acknowledge
b. Windowing
c. Sliding windows
5. No questions in ATM and ISDN PRI, only one question in X25, but lots of questions on Frame-relay.
6. Which of the following are the frame-relay LMI types used in Cisco routers?
7. What are the correct encapsulation type of frame-relay?
Cisco | Ietf (default is cisco)
8. What is LMI?
9. How to monitor Frame-relay activity on cisco routers?
Show interface s0, show frame-relay map
10. What is correct command syntax for configuring the secondary sub-interface?
Interface serial0.2 point-to-point
11. At least 8 questions on Access Lists (both IP and IPX access list, not much on Extended lists)
IP 1-99
Extended IP 100-199
IPX 800-899
Extended IPX 900-999
IPX SAP 1000-1099
Don't forget the implicit DENY ANY, so your access list must contain at least one PERMIT statement. Two steps to configure the access list
a. create the list access-list 1 deny 10.10.10.0 0.0.0.255 (Note the difference with subnet mask here)
b. associate it with an interface ip access-group access-list # {in | out}
12. Which command is used to view the access-list on serial0 interface? Show access-lists s0 (?)
13. ISDN questions are mostly in BRI, there is a question about the correction description of DCE/DTE, TA, NT1, CPE, Demar, CO and other Telco terminology.
14. There are two easy questions for ISDN, simply exclude the following obviously wrong answers (grin)
a. ISDN only offer voice service
b. ISDN only offer data service
c. The bandwidth of the combined B channels is less than 56k leased line
14. There is an ISDN question about the switch types and SPID. Basic-5ess, basic-

nderstand this question)
What password types control access to a router? (pw to access line, password to access EXEC mode, etc...)
What are the default encapslation and LMI type options?
What is the ICMP protocol for?
ISDN protocol standards? (Key in on the categories based on what letter the protocol starts with -- Q, I, E, etc...)
What two commands can be used to verify the address config.
Match the IPX encapsulation with the IOS encapsulation (i.e. Ethernet_II -> arpa, Ethernet_802.3 -> SAP, etc...)
How do you get help with a command syntax?
Reliable transport layer connections support? (acknowledgments, route selection, checkpoints, etc...?)
How are routing lops prevented?
How do you enable IPX on a router?
Which technology is appropriate for serial communications? (CPE, Demarc, DTE, CO, etc...)
What are the technology implications of 1/2 duplex Ethernet cards?
How do you log onto EXEC mode?
How do you enter commands on a router? (terminal, a file on a tftp server, etc?)
What is a MAC?
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... ;)
