CMDB is used for what?

• A. A firewall rule set
• B. A repository for assets and configuration items and their relationships
• C. An incident log
• D. A list of user accounts

Answer: (B)

A CMDB is a repository for assets and configuration items and their relationships, providing a centralized view of the IT environment. It stores items like servers, software, networks, services, and the connections between them, along with details such as ownership, version, location, and change history. This structure makes it possible to see how components depend on each other, so you can assess the impact of changes, quickly diagnose incidents, track assets over time, and maintain compliance. Other items such as firewall rules, incident logs, or lists of user accounts aren’t the centralized catalog of CIs and their interdependencies, so they don’t fulfill the same purpose as a CMDB.
