A. B. C. D.C.
The correct answer is D. Mobile and Remote Access (MRA) is a Collaboration Edge feature in Cisco Unified Communications Manager (CUCM) that allows remote users to securely access enterprise collaboration services, such as voice and video calling, instant messaging, and presence, via the Cisco Jabber application on their mobile devices or computers.
MRA works by allowing remote users to establish a secure connection to the corporate network over the internet using a Virtual Private Network ( VPN) connection. Once the VPN connection is established, the remote user's Jabber client can register with the CUCM server as if it were located within the corporate network. This allows the user to access all enterprise collaboration services just as if they were physically present in the office.
Option A is incorrect because MRA does not require a VPN connection for international calling. Users can make international calls using Jabber even without MRA, as long as their computer or mobile device has an internet connection.
Option B is incorrect because MRA does not require users to be within the corporate environment. MRA enables remote access to enterprise collaboration services from anywhere with an internet connection.
Option C is incorrect because MRA does require a VPN connection to provide secure remote access to enterprise collaboration services via Jabber. Without a VPN connection, remote users cannot securely connect to the corporate network and access enterprise services.
