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 I think it's outdated.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

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.
Good luck!!!
Nice.... I scheduled my next CCNA 31 jul....
Never seen that in the book :-) Will recheck, thanks !
I missed the BECN , FECN and DE which were already 2 questions on the exam. Stupid because it's so easy......
Thanks for your help !
Much appreciated
Hans
Can you expand on these terms, please?
Thanks!

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"
