The CMDB is used to understand service dependencies and support which activities?

• A. Impact analysis, change planning, and incident resolution.
• B. Marketing alignment, vendor selection, and budgeting.
• C. User access management, password recovery, and authentication.
• D. Compliance reporting, data retention, and archiving.

Answer: (A)

Understanding how service components relate and depend on each other lets IT teams predict ripple effects when something changes or when incidents occur. With a CMDB’s map of configuration items and their relationships, you can perform impact analysis to see which services and business processes would be affected, guide change planning by identifying all impacted components and necessary tests or rollbacks, and speed incident resolution by quickly pinpointing all affected parts and how they interact. This dependency awareness isn’t about marketing, IAM, or compliance tasks, which rely on other data and processes; the CMDB’s strength is mapping those dependencies to support impact analysis, change planning, and incident resolution.
