1. If a router cannot find a valid configuration file during the startup

sequence, what will occur?

The startup sequence will reset.

The router will prompt the user for a response to enter setup moe.

The startup sequence will halt until a !ali confi"uration file is acquire.The router will "enerate a efault confi"uration file #ase on the last !ali

confi"uration.

The router will monitor local traffic to etermine routin" protocol confi"uration

requirements.

2.

Refer to the exhibit. The network adinistrator has configured the router

with the interface I! addresses shown for the directl" connected networks.

!ings fro the router to hosts on the connected networks or pings

between router interfaces are not working. #hat is the ost likel"
