Our networking department is recommending we use a full duplex solution for an implementation. What is a KEY FEATURE of those?

The correct answer is A. Both systems can send and receive at the same time. Full duplex communication allows both parties to send and receive data simultaneously, like a phone call where both people can talk and listen at the same time. This contrasts with half duplex (one side transmits at a time, like a walkie-talkie - matching option B/C) and…

Explanation

Full duplex communication allows both parties to send and receive data simultaneously, like a phone call where both people can talk and listen at the same time. This contrasts with half duplex (one side transmits at a time, like a walkie-talkie - matching option B/C) and simplex (one-way only, direction cannot be reversed - matching option D). Full duplex is the most efficient mode because there is no waiting for the other side to finish before transmitting.
