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.
3. Refer to the exhibit. The PC, the routing table of which is displayed, is configured correctly. To which network device or interface does the IP address 192.168.1.254 belong?
PC
switch

4. Refer to the exhibit. Host A wants to access the Internet. Which combination of a Layer 2 address and a Layer 3 address will enable this access from host A?
Destination MAC: 0030.8596.DE83 Default gateway: 209.165.202.130
Destination MAC: 0030.8596.DE82 Default gateway: 172.16.9.2
Destination MAC: 0030.8517.44C4 Default gateway: 172.16.1.1Destination MAC: 0030.8517.44C4 Default gateway: 209.165.202.130
5. Refer to the exhibit. Communication between hosts X and Y is restricted to the local network. What is the reason for this?
The gateway addresses are broadcast addresses.
Host Y is assigned a multicast address.
Host X and host Y belong to different networks.
Host X is assigned a network address.
6. What is the result of using the clock rate 56000 command at the serial interface of the router?
The interface is configured as a DCE device.
The interface timers are cleared.
The FastEthernet interface is made to emulate a serial interface by assigning it a timing signal.
The IP address for the serial interface is configured.
