Which two Cisco Unified Communications Manager IM & Presence modules are checked by the system troubleshooter? (Choose two.)

CTI Manager is a Cisco Unified Communications Manager service used for telephony application integration via JTAPI and TAPI and is not an IM and Presence module included in the IM&P system troubleshooter checks.

XCP (Extensible Communications Platform) is the core messaging and federation infrastructure for IM and Presence; the system troubleshooter checks its router and associated services to confirm they are running and properly configured.

TFTP is a CUCM service responsible for delivering device configuration files and firmware images and is not part of the IM and Presence subsystem evaluated by the troubleshooter.

The Presence Engine processes SIP SUBSCRIBE and NOTIFY traffic and aggregates presence state from multiple sources; the system troubleshooter validates its operational status because failures here directly break presence visibility for all users.

Internal Database health is not a module checked by the IM and Presence system troubleshooter; database diagnostics are handled separately through Cisco Unified Serviceability tools.
