CompTIA Network+ (N10-007) — Question 29

A junior network technician is working in the field and needs to connect to the company's remote server, however, doing so will require the junior technician to use the public Internet. Because security is a concern, which of the following is the BEST method to use?

Answer options

• A. Telnet
• B. SSH
• C. SFTP
• D. VNC

Correct answer: B

Explanation

SSH (Secure Shell) is the best method for secure communication over an unsecured network like the public Internet, as it encrypts the data transmitted. Telnet is insecure because it does not provide encryption, making it vulnerable to interception. While SFTP provides secure file transfers and VNC allows remote desktop access, SSH is the most comprehensive option for secure terminal access.
