Refer to the exhibit. What action does the router take when a packet originates from 10.10.10.2 and is destined for 10.10.10.16?

A It floods packets to all learned next hops.
B It uses a route that is similar to the destination address.
C It queues the packets waiting for the route to be learned.
D It discards the packets.

Explanation

Routers forward packets by selecting the most specific matching route in the routing table. The connected route 10.10.10.0/28 covers addresses 10.10.10.0 through 10.10.10.15, so 10.10.10.16 does not match that network. Because no other route matches 10.10.10.16 and the routing table indicates that the gateway of last resort is not set, the router drops the packet.
