Difficulty: MediumNetworking Ports and Protocols

A network administrator is establishing security rules on an internal subnet router to support legacy macOS workstations accessing a centralized file server using Apple Filing Protocol (AFP). Which of the following ports should the administrator permit through the router to ensure proper AFP communication?

  1. TCP port 548Answer
  2. B
    TCP port 445
  3. C
    TCP port 427
  4. D
    TCP port 389

Answer

TCP port 548 is required to allow Apple Filing Protocol (AFP) network communication.
Apple Filing Protocol (AFP) operates over TCP port 548 to enable file management and sharing capabilities across local networks for macOS systems.

Step-by-Step Solution

1
Identify the target protocol required for network file access in the given scenario.
The scenario specifically asks for the port associated with Apple Filing Protocol (AFP).
Understanding protocol requirements is necessary to configure firewall access control lists correctly.
2
Map Apple Filing Protocol (AFP) to its standard TCP/IP port assignment.
AFP operates over TCP port 548.
Standard network protocols use default well-known ports defined by IANA.
