Ensurepass



Question 1:
Note: host 172.30.4.4 is wrongly given in Question the correct host must be 172.30.0.4

Answers: 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 .
