A technician is configuring a server that requires secure remote access .Which of the following ports should the technician use?212223443

1. Break Down the Problem

The technician needs to determine which ports are appropriate for secure remote access to a server. The options given are: 21, 22, 23, 44, and 443.

2. Relevant Concepts

We need to know what each port is commonly used for:

• Port 21: FTP (File Transfer Protocol) - not secure.
• Port 22: SSH (Secure Shell) - secure method for remote access.
• Port 23: Telnet - not secure.
• Port 44: Not commonly used; could refer to a specific service in some contexts but not standard.
• Port 443: HTTPS (Hypertext Transfer Protocol Secure) - used for secure web traffic, not direct remote server access.

3. Analysis and Detail

• Port 22 is the standard port for SSH, which provides a secure channel over an unsecured network.
• Port 443 is used for secure web traffic via HTTPS but is not typically associated with remote server access.

4. Verify and Summarize

Considering the purpose of secure remote access, the best choice is clearly SSH on port 22.

Final Answer

The technician should use port 22 for secure remote access.
