Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 159

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

Answer options

• A. MRA is used to access Webex cloud services only if authenticated with on-premises LDAP service.
• B. MRA is used to make secure PSTN calls by Cisco UCM only while on-premises authentication.
• C. MRA is used to make B2B calls through Expressway registration.
• D. MRA is used to access the collaboration services offered by Cisco UCM from off-premises network connections.

Correct answer: D

Explanation

The correct answer, D, accurately describes that MRA enables users to access Cisco UCM collaboration services from outside their local network. Option A is incorrect because MRA is not limited to Webex cloud services. Option B is also wrong as MRA is not solely for secure PSTN calls while on-premises. Option C is misleading since MRA is more about remote access rather than just B2B calls.
