100 Configuration Management Analyst Interview Questions and Answers

  1. What is Configuration Management (CM)?

    • Answer: Configuration Management is a systematic approach to identify, control, and maintain the integrity of a system's configuration throughout its lifecycle. It involves establishing and maintaining a baseline of the system, tracking changes, and ensuring that all components are consistent and compatible.

  2. Explain the CM lifecycle.

    • Answer: The CM lifecycle typically includes planning, identification, control, status accounting, and verification and audit. Planning defines the CM processes. Identification establishes a unique identifier for each configuration item. Control manages changes to the configuration. Status accounting tracks the configuration's current state. Verification and audit ensures the configuration meets requirements.

  3. What are Configuration Items (CIs)?

    • Answer: Configuration Items are the individual components or elements of a system that are managed as part of the configuration. Examples include hardware, software, documentation, and even processes.

  4. What is a baseline in CM?

    • Answer: A baseline is a formally reviewed and approved version of the configuration at a specific point in time. It serves as a reference point for future changes and helps ensure that the system remains consistent.

  5. Describe the change management process.

    • Answer: The change management process typically involves request submission, impact assessment, approval, implementation, testing, and closure. It ensures that all changes are properly evaluated, authorized, and implemented to minimize risk.

  6. What is version control?

    • Answer: Version control is a system for managing changes to files and documents over time. It allows for tracking different versions, reverting to previous versions, and collaborating on projects effectively.

  7. What are some popular version control systems?

    • Answer: Git, Subversion (SVN), Mercurial are popular version control systems.

  8. Explain the difference between Git and SVN.
