When a packet is determined to be on the local network, what happens?
Answer Options
The destination IP address is changed to the router IP address.
The destination MAC address is changed to the destination host's MAC address.
The destination MAC address is changed to the router's MAC address.
The source IP address is changed to the router's IP address.
Correct Answer: B
Explanation
When a packet is determined to be local to the sending host, ARP is used to resolve the MAC address for the IP address of the destination host, and the frame is sent directly to the host. The destination IP address is not changed throughout the network delivery process. The destination MAC address is only changed to the MAC address of the router if the packet is deemed to be remote from the immediate network. The source IP address is not changed throughout the routing process unless NAT is being used, and NAT is not used for local communications.
