Question
Enter IOS commands on the Dubai router to verify network operation and answer four multiple-choice questions. THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.
Note: If you are not sure about Frame-Relay, please read my Frame Relay tutorial.
To answer 4 questions below, you have to type show frame-relay map and show running-config to get its configuration. You can use the outputs of these commands to answer all 4 multiple-choice questions.
Dubai#sh frame-relay map
Serial1/0 (up): ip 10.60.0.2 dlci 704 (0x7B,0x1CB0), dynamic,
broadcast,, status defined, active
Serial1/0 (up): ip 10.60.0.3 dlci 196 (0xEA,0x38A0), dynamic,

Question 1
Explanation
To see what DLCI is used for the destination 10.60.0.4 we can check the output of “show frame-relay map” command:
Serial1/0 (up): ip 10.60.0.4 dlci 702 … -> The DLCI in this case is 702.
Serial1/0 (up): ip 10.60.0.4 dlci 702 … -> The DLCI in this case is 702.
Question 2
Explanation
From the output of “show frame-relay map” command, we learn the IP address of S-AMER is 10.60.0.3 and the DLCI used to reach there is 196 so B is the correct answer.
Question 3
Explanation
From the output of “show running-config” command we learn that interface S1/1 (connected to MidEast) does not declare any encapsulation -> It uses the default encapsulation HDLC.
Note: High-Level Data Link Protocol (HDLC) is the default WAN encapsulation for Cisco routers.
Question 4
Explanation
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.

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