Question: You are troubleshooting physical layer issues with the Gi0/1 interface in a router. You need to view and analyze the number of collisions detected on the interface.

Which command should you use?

Answer: show interfaces gi0/1

Question: You are troubleshooting physical layer issues with the Gi0/1 interface in a router. You suspect that a duplex mismatch error has occurred, and you need to determine the duplex settings configured on the interface.

Which commands could you use? (Choose two. Each response is a complete solution.)

Answer: show interfaces gi0/1

show interfaces gi0/1 status

Question: Review the output from the show interfaces fa0/1 command on the switch2 switch in the exhibit.

What is wrong with the fa0/1 interface in this example?

Answer: A duplex mismatch exists with the device on the other end of the connection.

Question: Consider the network shown in the exhibit.

When you run the show interfaces command on switch1, you observe a significant number of runts on the Gi0/1 interface.

What does this statistic indicate?

Answer: Collisions are occurring.

Question: You are reviewing the output of the show interfaces command for the Gi0/1 interface on a switch. You notice a significant number of CRC errors displayed.

What are the most likely causes? (Select two. Each response is a complete solution.)

Answer: EMI or cross-talk on the cable connected to the interface.

Collisions.

Question: A workstation is connected to a switch on the Gi 0/2 interface using a straight-through cable. The Ethernet interface in the workstation has been manually configured to use a 100 Mbps link speed in full-duplex mode.

Which of the following are true in this scenario? (Select three.)

Answer: The switch attempts to sense the link speed. If it can’t, the slowest link speed supported on the interface is selected.

If the link speed is 1000 Mbps or faster, full-duplex is used.

If the link speed is 10 Mbps or 100 Mbps, half-duplex is used.

Question:

Answer: The device connected to the Fa0/1 interface has auto-negotiation disabled.

Question:

Answer: There is latency on the WAN link.

Question:

Answer: The WAN provider is throttling bandwidth on the link.
