Note: host 172.30.4.4 is wrongly given in Question the correct host must be 172.30.0.4
Q1 What destination layer 2 addresswill be used in the frame header containing a packet for host172.30.4.4
The destination layer 2 address is a DLCI for frame-relay network. The destination host packet address is 172.30.0.4 corresponding DLCI is 702.
This can be confirmed by looking at the show frame-relay map output which shows the frame-relay map statements for layer 3 address to its corresponding layer 2 address IP 172.30.0.4 is mapped to DLCI 702 .
A static map to the S-AMER is required which command should be used to create this map
(a)Frame relay ip 172.30.0.3 704 broadcast
(b)Frame relay ip 172.30.0.3 196 broadcast
(c)Frame relay ip 172.30.0.3 702 broadcast
(d)Frame relay ip 172.30.0.3 344 broadcast
Answers: frame-relay map ip 172.30.0.3 196 broadcast
The show frame-relay map command above output provides the dynamic mapping for S-AMER (.3 as per topology the complete address is 172.30.0.3) to DLCI 196.
To create a static frame-relay map on dubai router to S-AMER we use the following command
Syntax: frame-relay map protocol protocol-address dlci [broadcast]
frame-relay map ip 172.30.0.3 196 broadcast
Which connection uses default encapsulation for serial interface for cisco routers?
(a)The serial connection to the MiddleEast Branch Office
(b)The serial connection to the DeepSouth Branch Office
(c)The serial connection to the North Centra Branch Office
(d)The serial connection to the Multinational Core
Answers: The serial connection to the MidEast branch office
By seeing the partial running config provided for Dubai router ... We can identify what encapuslation type is configured on each interface
Interface serial 1/0 : encapsulation frame-relay
Interface serial 1/2 and serial 1/3 : Both have encapsulation ppp
Interaface serial 1/1: Has no config info on encapsulation type this determines the default encapsulation (HDLC) is not changed on this interface.
Serial 1/1 is connection to MidEast branch office from Dubai router which has the default encapsulation.
