In a Cisco CCE deployment, CUCM (Cisco Unified Communications Manager) handles call signaling and agent phone management. Understanding how CUCM interacts with CCE routing is fundamental to the overall architecture.
Why the Correct Answer is Right: A is correct. In CCE, CUCM does not make routing decisions independently—it relies on ICM (via the PG) for routing intelligence. When a call arrives at CUCM that needs CCE handling, CUCM defers to ICM for routing instructions. ICM processes the call through its routing scripts and returns routing decisions that CUCM then executes. This is the documented CUCM-ICM integration model.
Why Each Incorrect Answer is Wrong: B is wrong because a CUCM Publisher is a single server holding the master database—it is not a 'logical relationship of physical servers.' That description better defines a CUCM cluster. C is wrong because CUCM does not ask CVP for routing instructions—CVP is an IVR/queuing platform, and routing decisions come from ICM. D is wrong because this is backwards—in a CUCM cluster, the Publisher holds the master Read/Write copy of the configuration database, while Subscribers receive replicated copies.
