Test Name: CCNA Test #640-407
I just finished the Cisco 's CCNA exam. I got 80%. Kinda of tough. Here's my braindump:
1.) Two questions on which is the network part and which is the node address part of both an IP and IPX address.
2.) Many answers could be found by process of elimination. Cisco put alot of silly possibile answers that are easy to check off.
3.) At least 10 question (possibly more) on the OSI layers.
a.) What level do JPEG, MPEG correspond to?
b.) What level do SQL, RPC correspond to?
c.) Question on the encapsulation process (data-segment-packet-frame-bit).
d.) Many other questions on each and every OSI layer.
4.) What context and how to configure banners (config)#banner motd #
5.) I had about 5 IP subnetting questions. Again, there were many silly possible answers that made it easy to eliminate to get the real answer.
6.) One question on the Cisco 7000 series switch/router and how to specify which slot/adapter/port# (not sure exactly though).
7.) About 5 qustions on access lists. Mainly standard access list but some extended ones.
8.) Some questions about matching a protocol to a certain OSI layer. eg. ICMP (which OSI layer -->network)
9.) About 3-4 questions on viewing and configuring Frame-Relay on a Cisco router (encapsulation/LMI type). This was a weak area for me.
10.) That's all I can remember. Good Luck!

MCNE, MCSE + I, A+, and now CCNA!
CCNA #640-403
Well took the exam 6/5/99, and pass with an 71%... Close I know!!!
The exam truely tests your understanding the CISCO ISO.
Know the OSI and the DOD models and know how and at what layers they interact.
I had two question on Apple talk. (hint, know all the access list numbers)
I had very few subnetting questions, but you must know what the valid host numbers are for a given subnet.
Most of the questions require you to pick several answers out of a large group.
Memorize where the protocols fit into the OSI model. <--------its a pain in the ass but do it!!!!
Best of luck,
BB
Hello all
I'd like to thank evey1 for posting all the tips. i passed CCNA test today with 74%, score could've been better if i had studied little harder, but hey i'm certified, it's all that matters. Some tips on the test.
I got lot of questions on IPX access list and in general.
Couple of Frame Relay questions.
Abt 5 ISDN questions
Lot of Subbnetting and ip addressing questions
And also lot on OSI modle, nothing on DoD
Couple IP access list questions
Know how to setup passwords on Console, Vty and all other different kind of passwords.
Know how to get help on commands like what happens if you do cl? and cl ?...know the difference.
Banner ends with your choice of diliminating character..i had that 1.
These were the main areas coverd...so focus on these.. and GOOD LUCK..

Misc. Info for CCNA
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.:)
I just took my CCNA 640-407 test today. I failed.
1. I had several questions in the OSI model.
a. four questions were choose the right description for Application, presentation, Session and Data
b. the presentation layer: pict and jpeg, midi and mpeg, ascii and ebcdic
c. the session layer: nfs, sql, rpc, asp
2. Frame tagging: 1. uniquely assigns a user-defined ID to each frame and
2. A unique user-defined identifier is placed in the header of each frame as it's forwarded throughout the switch fabric.
3. ICMP: destination unreachable, buffer full, hops, and ping
4. Quite of few IP addressing
5. here is a list of the external sources:
a. TFTP services
b. Virtual terminals
c. Network management stations
6. there are two questions on help. They are almost identical.
Help: I got the router#clock ? remember the question mark goes one space after the word
7. CTRL+A will move to the beginning of the command line
8. How do you set the console password:
#line con 0
#login
#password ----
9. Banner
router(config)#banner motd
this is a trick question because they will give you 7 answers and another will look like this:
router(config-if)#banner motd don't be fooled
10. on the cisco 7000 and 7500 the numbering syntax is slot/port adapter/port
11. configuring the clock rate.
router(config-if)#clock rate 56000
this is another trick question. look at the syntax closely
12. preventing routing loops
1. define a max hop count
2. split horizon
3. route poisoning
3. hold-downs
13. booting the system: router(config)#boot system ?
14. basic testing. how can you verify the IP address
a. testing with telnet will test all layers of the OSI reference model
b. ping will check connectivity between two hosts
c. trace can be used to discover routes to remote destinations
d. the sho int command will display line and data link protocol status
15. ISDN protocols: letters beginning with the letter "Q" specify switching and signaling
The rest of my questions can be found on the other braindumps

Test #640-407
Took the CCNA test shortly after completing my MCSE. All and all the test was pretty difficult, actually I studied my butt off by reading Lammle's book and a little bit of hands on and felt that I smoked it but my green passing bar at the end showed I barely made it. 70 questions is just too long, especially when each one makes you really think hard.
Anyway here's what I saw:
1. OSI was pretty major, there were several questions that asked which of the following best describes a particular layer.......and the answers were not anything like you'd read in a book. They are more deep in theory of what actually goes on there.
The hardest descriptions were with Application, Presentation, and Session. With Transport you need to know if it affects the top or bottom layer.
2. Verify Frame Relay..........sho frame ip/sho frame map
3. PVC is associated with Frame Relay
4. Logging into a console
line con 0
login
password
5. Oh yeah, know the difference from Router(ConfigT) and Router(Config-if)
6. ICMP.......destination unreachable, buffer full, hops, ping, etc.
7. How to change the CDP to 90
8. CO, Demarc, CPE, DTE, DCE.........just know what they are and where. They ask you to choose the ones that are correct, like the best 3 out of 5.
9. Administratively shutdown a router, what does the terminal display.
10. Verify Host/IP.........show host
11. Wild card masks, kind of bassackward question. where the answer ends up being 0.0.15.255
12. Hold downs..split horizon, route poison, triggered updates
13. Frame Tagging........user defined ID throughout fiber switch, header
14. How IP finds devices.......arp
15. Point of MAC address.
16. Half channel, being a one-way bridge.
17. IPX SAP
RouterA(Config-if)#ipx network 3200 encap hdlc sec
18. Know the parts of IPX network address.
19. As well as TCP/IP Remember that the default mask changes as the numbers change..go by the 0-126 A, 128-191 B, 192-223
20. What has the least amount of hosts C or D.
21. Know the broadcast address of a certain TCP/IP scheme.
22. LLC
23. Different ways to login to a Cisco router.
24. Different passwords needed.
25. Config mem
26. What affects running config.......there were some questions like this that you know the correct answers but only 2 of 3 are there and you are forced to pick one that doesn't quite make sense.
27. Same applies for the sh ipx int s0
28. Netware Frame types, know them........Ethernet-802.2=sap, etc.
29. Clockrate 56000
30. access list.
31. Know how the information goes through the OSI
Do Southern People Fart Badly
Data Segment Packet Frame Bit
Acronyms always helped me out.
32. Know the different bootsystem configurations.
33. ISDN Protocols........E..existing telephone network, I..concepts, terminoloy, services, Q..switching, signalling
34. ISDN, two similiar questions......real easy if you have a clue.
35. Frame relay, Cisco is default unless IETF
36. Banner is displayed at login
37. Cisco 7000 is slot/port adapter/port but the test says slot/port/adapter
38. What's the purpose of a host file, and where can it be stored.
39. Know the 3 places you can login from vty, aux, con
40. RIP
That's all I can remember at this time, there's a cramsession site for CCNA but it's not that great and some of the things are wrong so double check everything you find in these sites.........especially mine, for all you know I could be some maniac!!!!
Good luck and may the schwartz be with you,

Test name: Cisco CCNA
Test #: 640-407
I passed the CCNA exam on 5-13-99 on my first try with a 78%. The test is a standard style, 70 questions in 90 minutes, with passing being 68%.
The quick and dirty synopsis of what I was tested on is this:
About 10 questions directly related to the OSI model, including putting the steps of the lower 4 layers of data encapsulation in order, and the "What layer of the OSI model does this description fit?"
5 or 6 questions on subnetting IP.
About 5 questions related to access-lists. These were the "What will this list filter" or "Will this list do this result" type. There was also one dealing with the proper wild-card mask, but the answers were like nothing I had seen before.
A couple on what is used to prevent routing loops.
Most of the rest were router command syntax. What command will do this, and what does this command do type stuff.
No questions on Apple Talk.
I read two books. the CCNA study guide from Sybex press, and the CCNA exam certification guide from Cisco press. The Cisco press book was published in April '99 (I think) and is a first edition (I think). It had a lot of typo's in it, compared to the Sybex press book. The Sybex press book is good for an introduction to the concepts, but the Cisco press book is much better at preparing you for the test.
I have very little experience with Cisco Routers, and am fairly new to networking. This is not an easy test, but it's not impossible either. Go to Cisco's site and pull down any information they have about the exam objectives.
Good luck.

KEY POINTS TO BECOME CCNA
1) Know your OSI Model throughly. Just read Todd Lammle's OSI model line by line. For example, You would be thrown a question: Five steps of Encapsulation
1) Packets are put into logical frame.
2) User information is converted into data
3) Data is converted into segments
4) Segments are converted into datagrams and packets
5) Frames are put into bits
* 3 2 1 3 4
* 1 2 3 4 5
* 4 5 3 2 1
* 2 3 4 1 5 Answer
What kind of services are provided by presentation layer: JPGEG, MPEG, MIDI, TIFF so on What kind of services are provided by Session layer: NFS, RPC, SQL and so on.
2) Constrate on your DOD model. What is TCP, UDP and how they perform their functions.
3) Know your Cisco Commands. For example, how to enable Banners. You will see a A section of Banner's in Todd's book.
Router(Config#) banner motd #. You will be confused by saying that you must use this command in order to logon to the router which is wrong.
Choose the answer which hit enter and you will see a banner.
What are the three ways to modify your running-configuration file.
What are the three ways to display IPX interface e0. They are: sh ipx interface e 0, sh ipx int e0, and sh ipx interface ethernet 0.
4) Define access-list commands. You will be confused by seeing that
* Router(config-if) access-list 1 permit 172.16.20.1 0.0.0.0
You see a catch here. You define this command at Global level, not interface level.
You would define ip access-group 110 in at interface level. Keep this in mind where to define which command.
How to define a range of access list: For example, 172.16.10.0 - 172.16.40.0. what is the wild mask you will use.
Study Complex subnetting throughly. Meaning if you cross 8-bit boundry. For example: take an ip address 172.16.0.0. It is a Class-B network. You use 11-bit for subnetting. You will be asked to choose the correct range of host addresses. Todd has shown the chart which will help you a lot.
What's the default subnet mask for Class A, B and C.
On WAN: study ISDN and Frame Relay. Constrate more on ISDN. I only saw one question about Frame Relay which is (router-sub-if)# interface 0.1 point-to-point. Catch is you must define point-to-point or multipoint in order to complete the command.
ISDN: I had 4 questions. Study Reference points and Protocols.
For example E.I.Q.
E defines and existing line. I defines concept and terminology and Q defines switching. Question would be mixed. Just align them. Other questions are
ISDN provides Data only, Wrong
ISDN provides Voice only, Wrong
ISDN provides Both data and voice Correct
ISDN provides more bandwidth than fraction 56k T-1 Line. Correct
CDP: I am not sure about the command, but by default CPD update time is 60. How to change it to 90.
Test Name: Cisco Certified Network Associate
Test # 640-407
Failed this exam on my first try, There was a lot more emphasis on the networking essentials stuff than I had expected.
The course is broken down into 3 sections:
Introduction to Cisco Router configuration
Advanced Router configuration
Cisco LAN Switch Configuration
For the most part I have had a lot of experience with routers, so the command syntax questions were fairly simple for me, but definitely know all the possibilities to "copy running-config startup-config"
I was surprised to see a number of questions about loading banners onto the router's configuration and a number of questions on how to change terminal passwords, enable passwords, and enable secrets, know the difference.
There were the dreaded session layer standard questions, mpeg, jpeg, etc. I got burned on those simply because I didn't memorize them, quite a few questions on the DOD model as well as the OSI model, know them both!!
I'd guess 10 of the 70 questions were very difficult subnetting questions,
(I took 3 of those dry erase things into the booth with me and used them all!) If you don't have an excellent grasp of how many hosts, subnets, etc, forget about this test. Oh yeah, half of the questions gave subnets Cisco's way: 192.168.1.1 / 18
If you're not familiar with the 3 ways subnets can be represented as well as being able to blow through these types of questions, learn it before you waste $100.
