Resetting Database Replication and Broadcast in Cisco Unified CM Cluster 9.1

D.

The correct answer to this question is option B - Cisco Unified Serviceability.

Cisco Unified Serviceability is a web-based tool used for managing and troubleshooting Cisco Unified Communications Manager (CUCM) clusters. It provides a range of system-level services and tools to administer and maintain CUCM.

To reset all database replication and initiate a broadcast of all tables on a Cisco Unified CM cluster running version 9.1, an administrator can perform the following steps using Cisco Unified Serviceability:

1. Log in to the Cisco Unified Serviceability web interface using a web browser.
2. Select the "Tools" menu and then select "Control Center - Feature Services."
3. Select the publisher server in the list of servers displayed.
4. Click on the "Restart" button located on the top right corner of the page.
5. Choose the "Reset All Services" option and click on the "Submit" button.
6. Wait for the restart process to complete.

Once the restart process is completed, the database replication will be reset and all tables will be broadcasted on the cluster.

Option A - Real Time Monitoring Tool (RTMT) is a separate application used for monitoring and troubleshooting Cisco Unified Communications Manager and other Cisco collaboration applications. It does not provide the functionality to reset database replication and broadcast all tables.

Option C - Cisco Unified OS Administration provides system-level administration and management of Cisco Unified Communications Manager, including configuration and monitoring of system-level parameters, but does not provide the functionality to reset database replication and broadcast all tables.

Option D - Cisco Unified CM CLI provides command-line access to Cisco Unified Communications Manager and allows administrators to perform various administrative tasks, but does not provide the functionality to reset database replication and broadcast all tables.

Option E - Disaster Recovery System (DRS) is used for backing up and restoring Cisco Unified Communications Manager and other Cisco collaboration applications. It does not provide the functionality to reset database replication and broadcast all tables.
