Zorluk: ZorNetworking Ports and Protocols

A IT infrastructure consultant is setting up legacy macOS workstation compatibility on an enterprise network segment. The environment requires file transfer services via Apple Filing Protocol (AFP) as well as automated local network resource discovery via Service Location Protocol (SLP). Which TWO of the following port numbers must be permitted through internal host firewalls to allow these two services to function properly?

  1. TCP port 548Cevap
  2. TCP and UDP port 427Cevap
  3. C
    TCP port 445
  4. D
    TCP port 389

Cevap

The correct ports to permit are TCP port 548 for Apple Filing Protocol (AFP) and TCP/UDP port 427 for Service Location Protocol (SLP).
Apple Filing Protocol (AFP) operates on TCP port 548 to provide native file sharing capabilities for macOS endpoints. Service Location Protocol (SLP) operates on TCP and UDP port 427, allowing network devices to advertise and locate resources such as file shares and printers without prior manual configuration.

Adım Adım Çözüm

1
Identify the required network service for file transfers on legacy macOS clients.
The specified protocol is Apple Filing Protocol (AFP), which standardizes network file sharing for macOS.
AFP operates over TCP on standard port 548.
2
Identify the required protocol for network resource discovery.
The specified protocol is Service Location Protocol (SLP), which allows network clients to discover services like printers and file shares.
SLP listens on port 427 using both TCP and UDP transport protocols.
3
Evaluate the distractor ports to eliminate incorrect protocol matches.
TCP 445 corresponds to SMB file sharing, and TCP 389 corresponds to LDAP directory queries.
Neither SMB (445) nor LDAP (389) satisfies the specific requirement for AFP and SLP.
