Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 67

Scenario:
There are two call control systems in this item.
The Cisco UCM is controlling the DX650, the Cisco Jabber for Windows Client, and the 9971 Video IP Phone.
The Cisco VCS and TMS control the Cisco TelePresence MCU, and the Cisco Jabber TelePresence for Windows.
After adding SRST functionality the SRST does not work. After reviewing the exhibits, which of the following reasons could be causing this failure?

Answer options

• A. Device Pool cannot be default.
• B. The Cisco UCM is pointing to the wrong IPv4 address of the BR router.
• C. The router does not support SRST.
• D. The SRST enabled router is not configured correctly.

Correct answer: A

Explanation

The correct answer is A because a Device Pool set to default can lead to configuration issues with SRST functionality. Option B is incorrect as it pertains to addressing, which is a separate issue. Option C is not valid if SRST is enabled, and D is incorrect because it suggests a misconfiguration rather than the fundamental issue with the Device Pool.
