One of the devices is misconfigured
Answers

C.
The cable length is excessive
Answers
C.
The cable length is excessive
D.
One of the devices has a hardware issue
Answers
D.
One of the devices has a hardware issue
Suggested answer: C

Explanation:

In a half-duplex link, devices can only send or receive data at one time, not simultaneously. Late collisions occur when devices transmit data at the same time after waiting for a clear channel. One of the causes of late collisions is excessive cable length, which increases the propagation delay and makes it harder for devices to detect collisions. The link termination, device configuration, and device hardware are not likely to cause late collisions on a half-duplex link.
