could you solve both please ?

1. Within a local area network (LAN), suppose a source host A wants to send a datagram to a host B, whose IP address is 192.168. 1.250. How can A determine B's MAC address, knowing its IP address? Please list the adopted protocol and describe the process of address resolution. 2. Consider a datagram network using 8-bit host addresses. Suppose a router uses longest-prefix matching, and has the followine forwardine table: a) Suppose a datagram arrives at the touter, with destination address 01100111. To which interface will this datagram be forwarded using longest-prefix matching? b) Suppose a datagram arrives at the router, with destination address 10101010 . To which interface will this datagram be forwarded using longest-prefix matching? c) Suppose a datagram arrives at the router, with destination address 11111001 . To which interface will this datagram be forwarded using longest-prefix matching? d) How many addresses are associated with interface 2? c) How many addresses are associated with interface 4
