Which of the following combinations covers all the roles in Service Asset and Configuration Management?

The Service Desk Manager is a role within Service Operation, not a defined role within the SACM process, making this combination incorrect.

ITIL defines the primary roles within SACM as the Configuration Manager (process owner responsible for overall governance of SACM), the Service Asset Manager (accountable for tracking and managing all service assets throughout their lifecycle), and the Configuration Administrator/Librarian (responsible for day-to-day administration of the CMS and configuration item records). Together these three roles cover the strategic, managerial, and operational responsibilities required for the SACM process.

While Configuration Analyst and CMS/Tools Administrator are valid supporting SACM roles, including the Change Manager role is incorrect - Change Management is a separate ITIL process with its own distinct role set.

This option omits the Service Asset Manager, which is a key defined role in SACM specifically accountable for service asset management and cannot be excluded from a complete list of SACM roles.
