A technician is troubleshooting a 1000BASE-T link that is intermittent. The cable is Cat5e and the run is 70 meters (230 feet). The technician tests the cable and finds that the pairs are wired correctly, but the signal-to-noise ratio is poor. What is the most likely cause?

The cable is not Cat6, which is required for 1000BASE-T.

The wall jack is wired with T568A, which is not compatible with 1000BASE-T.

The cable is experiencing crosstalk or interference from nearby power cables.

The cable is too long for 1000BASE-T.

A technician is troubleshooting a 1000BASE-T link that is running at 100 Mbps. The cable is Cat5e and the run is 80 meters (262 feet). The technician checks the wall jack and finds it is terminated with T568B. What is the most likely cause of the reduced speed?

One of the four pairs in the cable is not properly terminated.

The wall jack is wired with T568B, which only supports 100 Mbps.

The cable is too long for 1000BASE-T.

The cable is Cat5e, which is not rated for 1000BASE-T.

A technician is troubleshooting a 1000BASE-T link that is down. The cable is Cat6 and the run is 50 meters (164 feet). The technician tests the cable with a network tester and finds that pairs 1-2, 3-6, and 4-5 are correct, but pair 7-8 is not terminated. What is the most likely result?

The link will run at 100 Mbps because only two pairs are needed.

The link will be down because 1000BASE-T requires all four pairs.

The link will run at 10 Mbps because only one pair is needed.

The link will run at 1000 Mbps because only three pairs are needed.
