Which Cisco term describes the grouping used by CUCM to allocate media resources during calls?

• A. Conferencing Bridge
• B. MTP
• C. Media Resource Group
• D. DSP

Answer: (C)

Media Resource Group.

In CUCM, media resources such as transcoders, MTPs, DSPs, and conferencing bridges are organized into a collection called a Media Resource Group. This grouping lets CUCM know which resources are available to handle a call’s media processing needs (like transcoding or mixing). When a call requires specific media resources, CUCM selects from the resources in the appropriate MR Group. You often pair MR Groups with a Media Resource Group List to define the preferred order and locality of resources for allocation. The other items are individual resources rather than the grouping mechanism: a conferencing bridge is one type of resource, an MTP is a specific resource used for transcoding/bridging, and a DSP is a processor that can be part of those resources.
