Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 68

How can you configure VCS Expressway to make sure an external caller cannot reach a specific internal address?

Answer options

• A. VCS Expressway only forwards calls to Cisco Unified Communications Manager who block calls.
• B. You make a transform on the VCS Expressway to direct the call to VCS Control, which can block the call.
• C. You add a search rule to block any call to the specific URI on the internal VCS Control.
• D. You add the specific URI in the firewall section of the VCS Expressway and block it.
• E. You block the call with a search rule that has a high priority in the VCS Expressway. E

Correct answer:

Explanation

The correct answer is D, as adding the specific URI to the firewall section of the VCS Expressway effectively blocks access to that address for external callers. Options A and B do not directly address the blocking of the specific internal address, while C suggests an internal solution that won't prevent external access. Option E, while addressing call blocking, does not specify the most effective method compared to option D.
