A. B. C. D. E.D.
The correct answer is C. Cisco CDR Repository Manager.
Call Management Records (CMRs) contain call-related data such as the calling and called numbers, call duration, and call quality metrics. CDR Analysis and Reporting (CAR) is a feature of Cisco Unified Communications Manager (CUCM) that allows administrators to generate reports based on CMR data.
The Cisco CDR Repository Manager service is responsible for writing CMR data into the CAR database. This service runs on each node in a CUCM cluster and is responsible for collecting CMRs from the Cisco CDR Agent service on each node and writing them to the CAR database.
The Cisco CDR Agent service is responsible for collecting CMRs from various sources such as CallManager, gateways, and phones. The Cisco CAR Scheduler service is responsible for scheduling and executing CAR reports. The Cisco CAR DB service is responsible for storing the report definitions and generated reports. Cisco Extended Functions is not a service in CUCM and is not related to CMRs or CAR.
