Hi

Just failed the CCNA exam:

Planning&Design 82%
Implementation&Operation 71%
Troubleshooting 88%
Technology 64%

Can someone help me explain what kind of questions I probably missed...

Unlucky :(

I was under the impression that Technology, which you scored 64% in,
encompassed a lot of the WAN stuff, so were there questions on ISDN,
Frame Relay etc that you found difficult?

Luckely enough almost no questions about ISDN. I really don't understand that U,
S/T etc stuff.
I think it's outdated. Here in NL you get an NT-1 installed and you just connect
your BRI wic to it.

Anyway.. They had some questions about subnetting, but not too much. Which is a
pity since I'm very familair with that :)
Think I missed some questions about Frame Relay and VTP

Re: CCNA.. tips
S/T is for when your provider gives you the NT-1 installed. The U is for
countries where they don't provide an NT-1. The U has a built in NT-1,
we use the U in the U.S.

Hans,

Join the crowd!  The first time I took the CCNA I failed because of the
technology section also.   I brushed up on Frame Relay, PPP and ISDN
and scored a 939 so don't worry.

1.  For frame relay know this:
     -configure the basics of poit to point
     - configure the basics of multipoint ((************remember to
have the command "no ip split horizon" in there if its multipoint.
     -be familiar with the basics "show frame-relay_______"n commands
and how to read the output.

2. For ISDN:
     -basic commands to get it going:(sw type in global and interface
mode, spid1, spid2 etc, dialer map command to map the ip to a phone
number)
     -interpret the show isdn status command. (layer 1, layer 2 and
layer 3 output)

3.  When you are comfortable with these things, the exam will go much
easier for you because you will not keep getting hammered on these once
you get a few correct.

4.  the 61% you scored means you aren't that far away anyway from doing
well on the WAN stuff.

Good luck!!!

On the CCNA they showed the interface statistics and asked what the BECN and
FECN numbers means.
Next question was about the DE value

 Short for backward explicit congestion notification. A Frame Relay message that
notifies the sending device that there is congestion in the network.
A BECN bit is sent in the opposite direction in which the frame is traveling,
toward its transmission source.

 Short for forward explicit congestion notification. A Frame Relay message that
notifies the receiving device that there is congestion in the network.
A FECN bit is sent in the same direction in which the frame was traveling,
toward its destination.

I couldn't find on the internet an explanation of the DE value but what I
understood is that packets with the DE bit set to 1 are "less important" and
therefore the switch can drop the packet if circuit is congested

Hans,

Yeah.  DE literally stands for "Discard Eligible"
