CompTIA A+ Core 2 (220-1002) — Question 290

A technician is updating a network switch at a location facility. The technician needs to ensure the data is not sent in plaintext over untrusted networks. Which of the following should the technician use? (Choose two.)

Answer options

• A. SSH
• B. SCP
• C. TFTP
• D. FTP
• E. RDP
• F. VNC

Correct answer: A, B

Explanation

SSH (Secure Shell) and SCP (Secure Copy Protocol) both provide encrypted communication, ensuring that data is not sent in plaintext. In contrast, TFTP, FTP, RDP, and VNC do not encrypt data, making them unsuitable for secure transmission over untrusted networks.
