CISCO试题回忆


Hello everyone,I have pass the CCNA2.0exam at 2000.8.13.
My grade is 870.
exam number is 640-507.
It has 65 items.given time is 135min,passing score is 822. in my pinion,CCNA2.0
is a bit hard than MCSE,but not so mush if you pass the MCSE by yourself(I mean
not dumped).The MCSE course will help you a lot, as the basis of it is very
helpful for you to understand the OSI 7 models and tcp/ip subnet addressing.If
you are not a MCSE,please study these concepts carefully as it has up to 10
items at lease in my exam. I have read my ICND book for three times hardly,and
do the bosom exam software(it’s realy a good one). The ICND book is very
important as there in my exam are 2 -3 items are taken from the book without a
little changed. the following is my memory about the exam: (the words of the
question may different)

1.drag & drop item:
just remember:data-->segment-->packet-->fram-->bit

2.what command to show hostname with ip address
: show host

3.in ’100BaseT’,what is ’Base’ stand for

c.the propotional?? link about the web(i can not remember the details)

5.IP address rule:

6.IP configuration item about subneting,3-4 items(it’s easy for MCSE)

7.the concept about the switch type ’fragment free’:
a.read the 50% of the data before forward
b.read the all of the data before forward
answer: a
note: there are 4 answers,one with the word’latancy’,the other is with ’wire
speed’ and these two are nothing with the question.But the fragment just read
the first 64 bytes before forward,and nothing with the remained two answer,i
think there may be a bug. so i chose ’a’

8.identify the start-up file loading from the ’exibit’ about the router’s setup

9.to retrieve the config file:copy start run

10.encapsulation: there are 2 items which would give you a graphic about
several node with some encapsulation type.the graphic is just the same one on
the ICND book.just remember to communication,the encapsulation type on both end
must be the same.

11.which command can show you the DLCI’s: show frame-relay

12.what is ’ipx access-list 1 deny 2b 4a’ stand for?
