Question 3

You recently implemented the configurations shown in the exhibit. After committing these changes, the community devices connected to AS-1 are not able to communication with the appropriate community devices connected to AS-2.
What must be to allow these community devices to communicate?

A. You must configure the ge-0/0/10 interface on AS-1 as the inter-switch link.

B. You must configure an isolation VLAN ID under the vlan-pri vlan on the AS-2 switch.

C. You must configure an isolation VLAN ID under the vlan-pri VLAN on both switches.

D. You must configure the ge-0/0/1 interface on both switches the inter-switch links.

E. You must configure to allow the ge-0/0/1 interface on AS-1 as the inter-switch.

Correct Answer: D
