Which of the following Cisco Unity Connection services notifies components of changes to the database?
A.
Connection DB Event Publisher
B.
Connection CM Database Event Listener
C.
Connection Message Transfer Agent
D.
Connection Branch Sync Service
Explanation:
The Connection DB Event Publisher service, which is a Cisco Unity Connection base service, notifies
components of changes to the Unity Connection database. Many Cisco Unity Connection services, including
base services, can be managed from the Control Center in Cisco Unity Connection Serviceability. However,
some status-only services, including Connection DB, Connection Server Role Manager, and Connection
Serviceability, cannot be managed from the Control Center and can be deactivated only from a command-line
interface (CLI).
The Connection Message Transfer Agent does not notify components of changes to the Unity Connection
database. The Connection Message Transfer Agent is a critical Unity Connection service that enables voice
mail messages to be delivered to the message store. Although Unity Connection will operate without this
service, voice mail messages cannot be delivered without it.
The Connection CM Database Event Listener does not notify components of changes to the Unity Connection
database. However, the Connection CM Database Event Listener, which is an optional Unity Connection
service, is capable of detecting changes in the Cisco Unified Communications Manager (UCM) database.
The Connection Branch Sync Service does not notify components of changes to the Unity Connection
database. The Connection Branch Sync Service, which is an optional Unity Connection service, enables Unity
Connection’s Survivable Remote Site Voicemail (SRSV) function.Cisco: Managing Services in Cisco Unity Connection 10.x (PDF)
