Welcome back! Here are the answers to the first of two Cisco certification exam training questions I posted yesterday...

CCNA:

Short answer: What command ties the dialer-list shown to the interface?

R1#conf t
R1(config)#dialer-list 7 protocol ip permit
R1(config)#interface bri0
R1(config-if)#____________

Answer: The command dialer-group 7 will do the job. Watch that list number!


CCNP / BSCI:

A. Less than one second.

B. 1 - 3 seconds.

C. 35 seconds.

I'll have the answers to the other set of questions posted later this morning, and a new set of questions as well. See you then!
