CCNA 1.Which of the following types of packets will be allowed entry when a serial interfaces inbound access list has been configured to prohibit entry for TCP and UDP ports 21, 23 and 25? (Select
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 p
ick 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..
Andy
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
later,
Valentino
CCNA
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
