1. 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.D632
• 0060.7320.D631
• 0040.8517.44C3
• 0009.B2E4.EE03
• 0010.C2B4.3421
2. What are three characteristics of CSMA/CD? (Choose three.)
• It monitors the media for presence of a data signal.
• After detecting a collision, hosts can resume transmission after a random timer has expired.
• A jam signal is used to ensure that all hosts are aware that a collision has occurred.
• Devices can be configured with a higher transmission priority.
• Data is transmitted only when the data signal is present.
• It uses a token system to avoid collisions.

In the graphic, Host A has reached 50% completion in sending a 1 KB Ethernet frame to Host D when Host B wishes to transmit its own frame to Host C. What must Host B do?
- Host B can transmit immediately since it is connected on its own cable segment.
- Host B must wait to receive a CSMA transmission from the hub, to signal its turn.
- Host B must send a request signal to Host A by transmitting an interframe gap.
- Host B must wait until it is certain that Host A has completed sending its frame.
