During the process of encapsulation, how does the PC determine if the packet is destined for a host on a remote network?
- By checking the ARP cache for the destination host MAC address
- By querying the DNS server for the information of the destination host
- By sending a broadcast to the local LAN segment to see if there is any response
- By performing the AND operation on the destination IP address and its own subnet mask
Explanation: When a PC needs to encapsulate a frame to send a data packet, it first performs an AND operation with its own IP and subnet mask, which yields the network address. Then it performs another AND operation using the destination IP and the same subnet mask. By comparing the two AND operations results, the PC knows if the destination is on the local LAN or on a remote network.
