Review Questions

The answers to these review questions appear in Appendix A, “Answers to Review Questions.”

1. If a PC on an Ethernet network attempts to communicate with a host on a different subnet, what destination IP address and destination MAC address will be placed in the packet/frame header sent by the PC?

   1. Destination IP: IP address of the default gateway. Destination MAC: MAC address of the default gateway.

   2. Destination IP: IP address of the remote host. Destination MAC: MAC address of the default gateway.

   3. Destination IP: IP address of the remote host. Destination MAC: MAC address of the remote host.

   4. Destination IP: IP address of the remote host. Destination MAC: MAC address of the local PC.

2. What protocol is used to request a MAC address that corresponds to a known IPv4 address on the local network?

   1. IGMP

   2. TTL

   3. ICMP
