Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Interfaces are local to a specific machine and define how adjacent layers interact within that system. Because different machines may use different hardware or operating systems, their internal interfaces do not need to be identical. As long as the peer-to-peer protocols used for communication are the same, the machines can successfully exchange data.
