Which service validates user credentials for MRA?

Which service validates user credentials for MRA?

• A. CUCM and IM&P
• B. Expressway-C and CUCM
• C. Expressway-E and CUCM
• D. MRA server

Answer: (B)

For remote access, the authentication path runs through the edge component that sits inside the enterprise and the central call-control server. When a remote user attempts to sign in, the Expressway-E forwards the credentials to the internal Expressway-C. The Expressway-C then communicates with Cisco Unified Communications Manager (CUCM) to validate the user against CUCM’s directory (and its integrated IM&P services as needed). In this flow, the actual credential check is performed by CUCM as coordinated by Expressway-C, not by the MRA edge alone. So the service that validates user credentials for MRA is the combination of Expressway-C and CUCM.
