(In the old days, this question was a multi-choice question but Cisco upgraded it into a lab-sim question. Therefore, instead of listing all the configuration as above, you have to type show frame-relay map and show running-config to get its configuration)

Question 1:

What destination Layer 2 address will be used in the frame header containing a packet for host 172.30.0.4?

A – 704
B – 196
C – 702
D – 344

?

Answer: C

Question 2:

A static map to the S-AMER location is required. Which command should be used to create this map?

A – frame-relay map ip 172.30.0.3 704 broadcast
B – frame-relay map ip 172.30.0.3 196 broadcast
C – frame-relay map ip 172.30.0.3 702 broadcast
D – frame-relay map ip 172.30.0.3 344 broadcast

?

Answer: B

Question 3:

Which connection uses the default encapsulation for serial interfaces on Cisco routers?

A – The serial connection to the MidEast branch office
B – The serial connection to the DeepSouth branch office
C – The serial connection to the NorthCentral branch office
D – The serial connection to the Multinational Core

?

Answer: A

Question 4:

If required, what password should be configured on the router in the MidEast branch office to allow a connection to be established with the Dubai router?

A – No password is required
B – Enable
C – Scr
D – Telnet
E – Console

?

Answer: D

Explanation

關鍵就在這第四題，照下面翻譯，大概就是，這道題沒有固定的答案，而是需要你在考試的時候自己show running-config，把密碼自己找出來，所以才有了很多版本的答案，作這道題還要注意的一點就是，注意S口使用的封裝類型，PPP就要SHOW RUN找密碼，如果是HDLC，那就直接選A吧，這個不用密碼。

明天3月1號，明天就去考NA了，雖然沒什么難度，但鑒于一直以前RP不咋樣，所以還是祝自己好運，可不要明天就大變題啊。

這道題的出處，http://www.9tut.com/，分享給大家，這是一個國外的NA題庫網，討論的人好像還比較多，畢竟英文是人家的母語，有優勢，對題的理解比我強多了，去看看說不定對你有幫助。

最后，祝大家也考試順利！

This question is not clear for a long time but now maybe the trick was solved. What Cisco wants to ask is the word used as password, not the type of connection, so in the exam you might see some strange words for answers like “En8ble”, “T1net”, “C0nsole”. All you have to do is to use the command “show running-config” as wx4 mentioned below to find the answer.

wx4 commented:

Q4: if password required which?
in my example it was connection to North!

How to figure out which pw is required?

#show running-config

1. check the interface to the router you need connection to. If there is “ppp authentication” you need a password!

2. you will find the password on the top of your running-config output

check the area:

username North password c0nsole
username xxxxx yyyyy
username…

in my case it was c0nsole, in your case it can be no password needed or a different password.

If you are still not clear, please read anton‘s comment:

A big question I noticed here was about the FR Lab regarding the password. You have to perform a show running-config and look for USERNAME and PASSWORD.
i.e.
username South_Router password c0nsol3
username North_Router password t31net

Obviously this has to be en PPP encapsulation, if asked for a posible password for SOUTH_ROUTER you pick c0nsol3, and for NORTH_ROUTER you pick t31net. If you’re running HDLC, i would pick “no password is required”.
