Explanation

Cisco IM and Presence (IMP) is the on-premises instant messaging solution and is a feature set that runs as nodes within a Cisco UCM cluster - not as a separate standalone server deployment. Since the organization already has UCM clusters at three locations, the correct approach for resilient IM is to expand each existing UCM cluster by adding IMP nodes to it. This provides local IM services and resilience at each site. Deploying a single central IMP server (D) creates a single point of failure. Deploying separate IMP servers outside of UCM clusters (B) misrepresents the architecture - IMP nodes must be part of the UCM cluster.
