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?
show interfaces gi0/1 description
show interfaces gi0/1
show interfaces gi0/1 status
show controllers gi0/1

show interfaces gi0/1

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.)
show interfaces gi0/1
show controllers gi0/1
show interfaces gi0/1 status
show interfaces counters
show interfaces gi0/1 description

show interfaces gi0/1 show interfaces gi0/1 status

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?
The line status is administratively down.
The protocol status is down.
The cable connecting the fa0/1 interface with the device on the other end is a straight-through cable, but needs to be crossed-over.
A duplex mismatch exists with the device on the other end of the connection.
|
A duplex mismatch exists with the device on the other end of the connection.

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?
The cable connected to this interface is a cross-over cable, but it should be a straight-through cable.
The cable connected to this interface is a straight-through cable, but it should be a cross-over cable.
Collisions are occurring.
There is EMI or cross-talk on the cable connected to this interface that is corrupting frames.

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.)
Collisions.
The cable connected to this interface is a straight-through cable, but should be a crossover cable.
The cable connected to this interface is a cross-over cable, but should be a straightthrough cable.
EMI or cross-talk on the cable connected to the interface.
The device on the other end of the cable is powered off or the other interface is administratively shutdown.

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.)
If the link speed is 10 Mbps or 100 Mbps, full-duplex is used.
The switch attempts to sense the link speed. If it can’t, the slowest link speed supported on the interface is selected.
The switch interface will display as administratively down.
If the link speed is 1000 Mbps or faster, half-duplex is used.
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.

Consider the network shown in the exhibit.
You have been experiencing intermittent connectivity issues with switch2. To check the status of the interfaces, you run the following commands:
switch2# show interfaces fa0/1 status Port Name Status Vlan Duplex Speed Type Fa0/1 connected 3 a-half a-100 10/100BaseTX switch2# show interfaces Gi0/1 status Port Name Status Vlan Duplex Speed Type Gi0/1 connected trunk a-full a-1000 1000BaseTX switch2# show interfaces Gi0/2 status Port Name Status Vlan Duplex Speed Type Gi0/2 connected trunk a-full a-1000 1000BaseTX What is the issue with this network?
The device connected to the Fa0/1 interface has auto-negotiation disabled.
There is a duplex mismatch on the Gi0/2 interface.
The device connected to the Gi0/1 interface has auto-negotiation disabled.
There is a link speed mismatch on the Gi0/1 interface.
There is a link speed mismatch on the Gi0/2 interface.
|
The device connected to the Fa0/1 interface has auto-negotiation disabled.

Your organization recently opened a branch office in a remote area. Because of its location, traditional WAN connectivity was not available, so you contracted with a satellite provider to connect the branch office network to your home office network.
Recently, your CEO conducted a video conference with the employees at the branch office. The employees complained that the video was choppy and the audio was frequently out of sync with the video.
What is the most likely cause of this poor WAN performance?
There is an IP address misconfiguration issue between the WAN interfaces on both ends of the link.
The WAN interface on the router at the branch office has been disabled.
There is a data link encapsulation protocol mismatch between the WAN interfaces on both ends of the link.
There is latency on the WAN link.
There is an authentication misconfiguration issue between the WAN interfaces on both ends of the link.
