Difficulty: EasyNetworking Ports and Protocols

Match each network protocol on the left with its corresponding default port number on the right.

  • SSH (Secure Shell)Port 22
  • HTTPS (Hypertext Transfer Protocol Secure)Port 443
  • RDP (Remote Desktop Protocol)Port 3389
  • SMB (Server Message Block)Port 445

Answer

SSH matches Port 22, HTTPS matches Port 443, RDP matches Port 3389, and SMB matches Port 445.
SSH maps to Port 22, HTTPS maps to Port 443, RDP maps to Port 3389, and SMB maps to Port 445 according to standard IANA well-known port numbers tested in CompTIA A+ Core 1.

Step-by-Step Solution

1
Identify the standard port for SSH (Secure Shell).
SSH corresponds to TCP port 22.
SSH provides encrypted console logins on port 22.
2
Identify the standard port for HTTPS (Hypertext Transfer Protocol Secure).
HTTPS corresponds to TCP port 443.
HTTPS encrypts web data transport over port 443.
3
Identify the standard port for RDP (Remote Desktop Protocol).
RDP corresponds to TCP port 3389.
Microsoft Remote Desktop Protocol uses port 3389 by default.
4
Identify the standard port for SMB (Server Message Block).
SMB corresponds to TCP port 445.
Direct SMB file sharing listens on TCP port 445.
