Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 120

Which protocol runs over TCP port 22?

Answer options

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

Correct answer: A

Explanation

The correct answer is SSH, as it is specifically designed to operate over TCP port 22 for secure communications. NETCONF, while related, does not specifically run over this port. HTTP operates over port 80, and Telnet uses port 23, making them incorrect options.
