David notices a lack of documentation and scattered spreadsheets. Which IT management tool should he implement to centralize information about IT assets and their relationships?

• A. Asset Inventory
• B. Patch Management
• C. CMDB
• D. Knowledge Base

Answer: (C)

The need is to have a centralized, interconnected view of IT assets and how they relate to each other. A Configuration Management Database collects configuration items—servers, software, networks, services—and records their relationships, versions, and dependencies. This creates a single source of truth that makes it possible to see how a change to one asset could affect others, track the lifecycle of components, and support IT service management processes like incident and change management. The other options don’t provide this relational, governance-focused view: Asset Inventory catalogs assets but not their interconnections; Patch Management focuses on applying updates rather than modeling assets and their relationships; Knowledge Base stores documentation but not a structured model of assets and how they interconnect.
