CompTIA Network+ (N10-007) — Question 296

A network technician has provisioned a new Linux instance in a public cloud provider's IaaS environment. The technician did not install a graphical user interface.
The technician wants to connect to the server's public IP address securely to start a console session. Which of the following remote access methods should the technician use?

Answer options

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

Correct answer: A

Explanation

SSH is the correct choice because it provides a secure way to access the Linux server's command line over an unsecured network. Telnet is not secure, as it transmits data in plain text, while VNC and RDP are primarily used for graphical interfaces, which are not applicable in this case since no GUI is installed.
