Refer to the exhibit. Host A and B are unable to communicate with
each other. What is the reason for this?
The gateway addresses are network addresses.
Refer to the exhibit. Host B attempts to establish a TCP/IP session
with host C. During this attempt, a frame was captured at the
FastEthernet interface fa0/1 of the San Francisco router. The packet
inside the captured frame has the source IP address 10.10.1.2, and
the destination IP address is 10.31.1.20. What is the destination
MAC address of the frame at the time of capture?
0060.7320.D631

e-mail message from HostB to the e-mail service that is running on
ServerA?
Router B uses a Layer 3 network address to route the packet.
Refer to the exhibit. Host A is configured with the correct IP address
for the default gateway of the router R1 FastEthernet0/1 interface.
How will a packet that is sent from host A to host B be handled by
