Question

Quizplus · Accepted Answer

A loopback plug is used to test a network cable by creating a loop in the data transmission, sending data back to the same device. This is useful for troubleshooting network connectivity issues or testing cables for faults. It would not be used for testing a USB port or capturing network packets, and finding the max speed of a connection would require a different type of test.
