Question

AFP runs by default on TCP port?
1) 20
2) 21
3) 22
4) 23

Answer 1

AFP runs by default on TCP port 548, which is not listed among the options provided in the question.

Step-by-step explanation:

The student is asking about the default TCP port on which the Apple Filing Protocol (AFP) runs. AFP is a protocol that allows Macintosh computers to share files with each other. The answer to the question is that AFP runs by default on TCP port 548, which is not one of the options listed in the question. Therefore, if the question is strictly referring to the options given (20, 21, 22, 23), it seems there may be a mistake since none of those ports are associated with AFP.
