Which statement best describes a media resource group within CUCM?

• A. A collection of DSP resources only.
• B. A policy used to enforce QoS on media streams.
• C. A logical grouping of media resources used by CUCM for allocation.
• D. A log of media resource usage for billing.

Answer: (C)

A media resource group is the logical container that groups all the media resources CUCM can use during a call. It isn’t limited to DSP resources; it can include MOH servers, conference bridges, transcoding resources, fax servers, and other media functions. By organizing resources into groups, CUCM can allocate the right resources when processing a call. These groups are then referenced by a media resource group list to control which resources are considered (and in what order) for devices in a given location or device pool. This setup enables efficient resource allocation and failover if some resources are busy or unavailable. It’s not a QoS policy and not a usage log; it’s specifically about grouping resources for allocation.
