Refer to the exhibit.

A junior engineer updated a branch router configuration. Immediately after the change, the engineer receives calls from the help desk that branch personnel cannot reach any network destinations .

Which configuration restores service and continues to block 10.1.1.100/32?
A . route-map FILTER-IN deny 5
B . ip prefix-list 102 seq 15 permit 0.0.0.0/32 le 32
C . ip prefix-list 102 seq 5 permit 0.0.0.0/32 le 32
D . route-map FILTER-IN permit 20

Answer: D

Explanation:

By using “deny” keyword in a route-map, we can filter out the prefix specified in the prefix-list.

But there is an implicit “deny all” statement in the prefix-list so we must permit other prefixes with “permit” keyword in the route-map.
