Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 84

An engineer must ensure that Expressway-E listens and only its legit sender of such traffic is Expressway-C. Which port must be opened to accomplish this task?

Answer options

• A. 2000
• B. 2111
• C. 2222
• D. 2223 C

Correct answer:

Explanation

The correct port to open for communication between Expressway-E and Expressway-C is 2222. Ports 2000, 2111, and 2223 do not facilitate the required signaling for this specific communication path, thus making them incorrect options.
