Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 359

Which TCP port is used to connect to a network device by using Telnet?

Answer options

• A. 23
• B. 69
• C. 400
• D. 830

Correct answer: A

Explanation

The correct answer is A, as Telnet uses TCP port 23 for communication. Options B, C, and D are incorrect because port 69 is used for TFTP, port 400 is not a standard port for Telnet, and port 830 is typically associated with NETCONF.
