What is the primary purpose of a CMDB in ITIL?

• A. CMDB stores user data for service desks.
• B. CMDB tracks financial costs of services.
• C. CMDB stores configuration items and their relationships to support impact analysis, change management, and service impact.
• D. CMDB replaces asset inventory entirely.

Answer: (C)

The main idea is that a CMDB stores information about configuration items and how they relate to one another. This map of CIs and their connections lets you see what components make up a service, how they depend on each other, and what would be affected if one item changes or fails. That visibility supports impact analysis, so you can assess risk before making changes, supports change management by informing planning and approval with accurate dependency data, and enables quicker understanding of service impact when incidents occur. It’s not about storing user data or tracking financial costs, and it doesn’t replace asset inventory entirely. Instead, it complements asset management by focusing on configuration items and their relationships to enable effective service management.
