Troubleshooting Network Connectivity Issues

A user reports network resources can no longer be accessed.

The PC reports a link but will only accept static IP addresses.

The technician pings other devices on the subnet, but the PC displays the message Destination unreachable.

Which of the following are MOST likely the causes of this issue? (Choose two.)

A.

Damaged cables

B.

Crosstalk

C.

Bent pins

D.

TX/RX reverse

E.

VLAN mismatch

F.

Duplex mismatch.

CE.

The two most likely causes of the issue described in the question are:

A. Damaged cables F. Duplex mismatch

Explanation:

When a user reports that network resources can no longer be accessed and the PC reports a link but will only accept static IP addresses, it is likely that there is a problem with the network connection.

If the technician pings other devices on the subnet, but the PC displays the message Destination unreachable, this indicates that the PC is unable to communicate with other devices on the network.

One possible cause of this issue is damaged cables. If the cables connecting the PC to the network are damaged, this can cause connectivity problems. For example, if one or more wires inside the cable are broken or frayed, this can cause intermittent connectivity issues or a complete loss of connectivity.

Another possible cause of the issue is a duplex mismatch. Duplex mismatch occurs when two devices on a network are configured to use different duplex settings (half-duplex or full-duplex). This can cause collisions and other communication problems, leading to connectivity issues.

The other answer choices are less likely to be the cause of the issue. Crosstalk, bent pins, and TX/RX reverse can all cause connectivity issues, but they are less common than damaged cables or duplex mismatch. A VLAN mismatch would likely result in the PC being unable to communicate with devices on other VLANs, rather than devices on the same subnet.
