What is the purpose of Mobile and Remote Access (MRA) in Cisco collaboration?

• A. To let Jabber/Webex App endpoints register securely from outside the network.
• B. To enable automatic endpoint firmware upgrades.
• C. To route all calls through a central media server.
• D. To manage licensing for endpoints.

Answer: (A)

Mobile and Remote Access focuses on letting Jabber and Webex App endpoints register securely from outside the corporate network, without needing a VPN. It achieves this by routing signaling through Cisco Expressway edge components (Expressway-C in the enterprise and Expressway-E in the perimeter) so external devices can authenticate and connect to Cisco Unified Communications Manager and related services over a secure TLS tunnel, even through NAT and firewalls. This enables remote users to register, sign in, and access calling, presence, voicemail, and meetings while staying protected.

Other options aren’t the primary goal: automatic firmware upgrades aren’t what MRA provides—that’s handled by separate update mechanisms. Routing all calls through a central media server isn’t the purpose of MRA, which is about secure remote registration and traversal for endpoints; and licensing management for endpoints is a separate concern outside the scope of this feature.
