Which tool is used to help determine the scale and performance of a Cisco Unified Presence multicluster deployment?

The Presence User Profile defines the feature set assigned to users within a Cisco Unified Presence deployment, making it the reference point for determining scale and performance in multicluster scenarios. Administrators use it to assess how presence features are distributed and resourced across clusters. It is the designated planning artifact for multicluster capacity decisions.

The Presence Capacity Planning Tool is a separate utility and is not the tool specifically referenced for determining scale and performance in a multicluster deployment context.

Cisco Unified Real Time Monitoring Tool (RTMT) is used for live system monitoring and alerting, not for planning or determining deployment scale.

Cisco Unified Presence Serviceability provides service management and diagnostic functions, not deployment capacity planning.

Cisco Unified Serviceability is a general administrative tool for Unified Communications Manager and is not specific to Presence multicluster deployment planning.
