CCNA: Cisco Certified Network Associate — Question 1057

Which protocol is used for secure remote CLI access?

Answer options

• A. Telnet
• B. HTTP
• C. HTTPS
• D. SSH

Correct answer: D

Explanation

SSH (Secure Shell) is the correct answer as it provides a secure channel over an unsecured network for remote CLI access. Telnet, HTTP, and HTTPS do not offer the same level of security for remote command line access, with Telnet being particularly insecure as it transmits data in plaintext.
