CompTIA Network+ (N10-009) — Question 100

Which of the following ports should a network administrator enable for encrypted log-in to a network switch?

Answer options

• A. 22
• B. 23
• C. 80
• D. 123

Correct answer: A

Explanation

Port 22 is used for SSH, which provides encrypted communication for secure log-in to network devices. Port 23 is typically associated with Telnet, which is not secure, while port 80 is used for HTTP traffic and port 123 is for NTP, which are not related to secure log-in.
