Which team is responsible for approving or denying change requests in an ITIL-based change management process?

• A. Service Desk
• B. Change Manager
• C. CAB
• D. Security Team

Answer: (C)

In ITIL-based change management, the approval or denial of change requests is handled by the Change Advisory Board. The CAB is a cross-functional group that reviews proposed changes for risk, impact on services, resource needs, and scheduling, and then decides to authorize, defer, or reject the change. The Change Manager coordinates the process and chairs CAB meetings, but the authority to approve lies with the CAB. For urgent changes, an ECAB handles expedited approvals. The Service Desk handles incident logging and user requests, and the Security Team provides input on security implications, but neither acts as the primary approval body.
