Explanation / Answer

Ans 1: b

Router records a routing table listing what route should be used to forward a data packet, and through which physical interface connection.

When router receives any packet, router checks destination address and finds longest-prefix match in IP routing table to find outgoing interface.

And 2: d

IP verifies the destination IP address in the IP header corresponds to an IP address assigned to a router interface.
