    B. The destination MAC address is changed to the destination host’s MAC address.C. The destination MAC address is changed to the router’s MAC address.
    D. The source IP address is changed to the router’s IP address.
  10. How does the sending host know if the destination is local or remote in respect to
    its immediate network?

    A. The host compares the IP address to its internal routing table.
    B. The host performs ANDing on its subnet mask and the destination IP address
    comparing the result to its own network address.
    C. The host performs ANDing on the destination subnet mask and the destination
    IP address, comparing the result to its own network address.
    D. The IP address is verified to be local to its network via ICMP.

    address.
    B. The router decapsulates the packet and inspects the destination IP address.
    C. Routers do not need to decapsulate packets to inspect the destination IP
    address.
