Question

which media communication type does not require media arbitration in the data link layer?
full - duplex
deterministic
controlled access
half - duplex

Explanation:

In full - duplex communication, devices can send and receive data simultaneously on separate channels. Since there is no contention for the same communication medium in terms of sending and receiving at the same time, there is no need for media arbitration in the data link layer. Deterministic, controlled access, and half - duplex may involve situations where multiple devices need to share or access the medium in a coordinated way, thus requiring arbitration.

Answer:

A. full-duplex
