You need to recommend a solution to remediate the Exchange Server 2010 service failures. The solution must meet the technical requirements. What should you include in the recommendation?

In Service Manager 2012, an incident event workflow can be configured to trigger automatically when an incident meeting defined criteria - such as an Exchange service failure alert - is created or updated. By attaching a runbook activity to the workflow, Service Manager calls an Orchestrator runbook that executes remediation steps such as restarting services or failing over components. This end-to-end automation satisfies technical requirements for self-healing service failure remediation with no manual steps required.

A dependent activity requires a prior activity to complete and is used for sequencing manual or semi-automated tasks; it does not invoke Orchestrator runbooks for automated remediation.

A service request workflow is initiated by end-user requests through the self-service portal, not by system-detected failure events, so it would not trigger on an Exchange service failure.

A service request workflow combined with a runbook activity is user-initiated rather than event-driven and cannot be automatically triggered by infrastructure failure incidents.
