You have created an IP-IP tunnel which will traverse interface at-0/1/0 and you would like to make
sure that the tunnel is operational. Which operational-mode command should you use to verify that
the IP-IP tunnel interface is up?

Devices S1 and S2 have the interface configurations as shown in the exhibit. You attach ge-0/0/0
on S1 to ge-0/0/0 on S2. You attach ge-0/0/1 on S1 to ge-1/0/20 on S2. However, the ae0
interface remains down on both S1 and S2. What should you change to cause the ae0 interface to

come up?

You want to configure a redundant trunk group on a switch. You want ge-0/0/0.0 to be the default

continue using ge-0/0/1.0 until ge-0/0/1.0 fails. Which configuration will accomplish this scenario?
