Which of the following should be available to the Service Desk? (1) Known Error Data (2) Change Schedules (3) Service Knowledge Management System (4) The output from monitoring tools

Excluding monitoring tool output (4) is incorrect because real-time event data from monitoring tools is critical for the Service Desk to detect, correlate, and respond to incidents proactively.

Excluding the SKMS (3) is incorrect because the Service Knowledge Management System is a primary resource the Service Desk uses to access knowledge articles, CI records, and diagnostic guidance.

Excluding Known Error Data (1) is incorrect because Known Errors provide documented workarounds and root cause information that the Service Desk relies on to resolve recurring incidents more efficiently.

All four items are essential Service Desk resources: Known Error Data enables faster incident resolution by referencing prior documented solutions, Change Schedules allow the Service Desk to correlate incidents with recent changes, the SKMS provides the central knowledge base for diagnosis, and monitoring tool output delivers real-time visibility into service health and active failures.
