Hotspot Question
R1 is configured with the default configuration of OSPF. From the following list of IP addresses configured on R1, which address will the OSPF process select as the router ID?
A. 192.168.0.1
B. 172.16.1.1
C. 172.16.2.1
D. 172.16.2.225
Answer: A
Explanation:
The Router ID (RID) is an IP address used to identify the router and is chosen using the following sequence:
+ The highest IP address assigned to a loopback (logical) interface. + If a loopback interface is not defined, the highest IP address of all active router’s physical interfaces will be chosen.
+ The router ID can be manually assigned
In this case, because a loopback interface is not configured so the highest active IP address 192.168.0.1 is chosen as the router ID.

Hotspot Question
If required, what password should be configured on the DeepSouth router in the branch office to allow a connection to be established with the MidEast router?
A. No password is required.
B. Enable
C. Secret
D. Telnet
E. Console
Answer: B
Explanation:
In the diagram, DeepSouth is connected to Dubai’s S1/2 interface and is configured as follows:
Interface Serial1/2
IP address 192.168.0.5 255.255.255.252
Encapsulalation PPP ; Encapsulation for this interface is PPP
Check out the following Cisco Link:

Here is a snipit of an example:
Network Diagram
If Router 1 initiates a call to Router 2, Router 2 would challenge Router 1, but Router 1 would not challenge Router 2. This occurs because the ppp authentication chap callin command is configured on Router 1. This is an example of a unidirectional authentication. In this setup, the ppp chap hostname alias-r1 command is configured on Router 1. Router 1 uses “alias-r1” as its hostname for CHAP authentication instead of “r1.” The Router 2 dialer map name should match Router 1’s ppp chap hostname; otherwise, two B channels are established, one for each direction.
What would be the destination Layer 2 address in the frame header for a frame that is being forwarded by Dubai to the host address of 172.30.4.4?
A. 825
B. 230
C. 694
D. 387
Answer: C
Explanation:
According to command output 172.30.4.4 is using the 694 dlci value. http://www.cisco.com/en/US/docs/ios/12_2/wan/command/reference/wrffr4.html#wp1029343
QUESTION 64
Hotspot Question
Which connection uses the default encapsulation for serial interfaces on Cisco routers?
A. The serial connection to the NorthCoast branch office.
B. The serial connection to the North branch office.
C. The serial connection to the Southlands branch office.
D. The serial connection to the Multinational Core.
Answer: B
Explanation:
Cisco default encapsulation is HDLC which is by default enabled on all cisco router. If we want to enable other encapsulation protocol(PPP,X.25 etc) we need to define in interface setting. But here except s1/1 all interface defined by other encapsulation protocol so we will assume default encapsulation running on s1/1 interface and s1/1 interface connected with North
QUESTION 65
Hotspot Question
A static map to the S-AMER location is required. Which command should be used to create this map?
A. frame-relay map ip 172.30.0.3 825 broadcast
B. frame-relay map ip 172.30.0.3 230 broadcast
C. frame-relay map ip 172.30.0.3 694 broadcast
D. frame-relay map ip 172.30.0.3 387 broadcast
Answer: B
Explanation:
frame-relay map ip 172.30.0.3 230 broadcast 172.30.0.3 is S-AMER router ip address and its configure on 230 dlci value. Check “show frame-relay map ” output in the diagram.
QUESTION 66

A. debug chap authentication
B. debug authentication
C. debug chap ppp
D. debug ppp authentication
