CompTIA A+ Core 2 (220-1002) — Question 418

A technician needs to connect to a network switch in a remote location. The technician wants to make sure the data passed over the wire is encrypted so it cannot be read by someone using a sniffer. Which of the following connection protocols should the technician use?

Answer options

• A. Telnet
• B. SSH
• C. SMB
• D. HTTP
• E. SFTP

Correct answer: B

Explanation

SSH (Secure Shell) is the correct choice because it provides a secure channel over an unsecured network by using encryption. In contrast, Telnet transmits data in plain text, making it vulnerable to sniffing; SMB and HTTP do not inherently offer encryption for data in transit, and while SFTP is secure for file transfers, it is not the primary choice for accessing a switch.
