Configuration Management Advisor Interview Questions

  1. What is Configuration Management (CM)?

    • Answer: Configuration Management (CM) is a systematic approach to identifying, controlling, and auditing changes throughout the system life cycle. It ensures that all aspects of a system (hardware, software, documentation) are properly tracked, managed, and controlled to maintain its integrity and functionality.

  2. Explain the importance of CM in software development.

    • Answer: CM is crucial in software development for several reasons: it improves collaboration, reduces errors, manages risks, improves traceability, simplifies maintenance, and ensures regulatory compliance. It enables teams to manage complex projects effectively and deliver quality software efficiently.

  3. What are the key principles of CM?

    • Answer: Key principles include identification, control, status accounting, verification, and audit. These principles ensure that changes are tracked, authorized, implemented, and verified correctly, maintaining the integrity and consistency of the configuration.

  4. Describe the CM lifecycle.

    • Answer: The CM lifecycle generally involves planning, identification, control, status accounting, verification, and audit. This iterative process continues throughout the system's lifespan, adapting to changes and ensuring consistency.

  5. What are some common CM tools?

    • Answer: Popular CM tools include Git, SVN, Ansible, Puppet, Chef, SaltStack, and Jenkins. The choice depends on the specific needs and scale of the project.

  6. Explain version control and its role in CM.

    • Answer: Version control is a crucial component of CM, tracking changes to files over time. It allows for easy rollback to previous versions, collaboration among developers, and a clear history of modifications. Examples include Git and SVN.

  7. What is a baseline in CM?

    • Answer: A baseline is a formally approved specification of a system at a specific point in time. It serves as a reference point for future changes and ensures that modifications are controlled and tracked.

  8. How do you manage configuration changes?

    • Answer: Configuration changes are managed through a formal process, typically involving a change request, review, approval, implementation, testing, and verification. This ensures that changes are authorized and properly integrated into the system.

  9. Describe the process of auditing a configuration.

    • Answer: Auditing involves verifying that the system's configuration matches the approved baseline and that all changes have been properly documented and approved. This ensures compliance with standards and regulations.

  10. What are the challenges of CM?

    • Answer: Challenges include managing complexity, ensuring team collaboration, dealing with conflicting changes, maintaining consistency across environments, and integrating with other development processes. Effective CM strategies must address these issues.

  11. Explain the difference between configuration management and change management.

    • Answer: Configuration management focuses on identifying, controlling, and auditing the system's configuration. Change management focuses on the process of managing and approving changes to that configuration. They are closely related but distinct processes.

  12. How do you handle conflicts in version control systems?

    • Answer: Conflicts are resolved using the version control system's merge tools, manually comparing and integrating changes. Communication and collaboration are key to efficiently resolving these conflicts.

  13. What is a configuration item (CI)?

    • Answer: A configuration item is any hardware or software component, document, or other element that is part of a system's configuration and is subject to CM processes.

  14. What is the purpose of a CM plan?

    • Answer: A CM plan outlines the processes, procedures, and tools used to manage the system's configuration throughout its lifecycle. It ensures consistency and efficiency in CM activities.

  15. How do you ensure traceability in CM?

    • Answer: Traceability is ensured through proper documentation, version control, and a well-defined change management process. This allows for tracing changes back to their origin and understanding their impact on the system.

  16. What are some best practices for CM?

    • Answer: Best practices include using version control, establishing clear processes, automating tasks, regularly auditing, training personnel, and continuously improving CM processes.

  17. Explain the role of automation in CM.

    • Answer: Automation streamlines CM processes, reducing manual effort and improving efficiency. It helps in tasks like build automation, deployment, and testing.

  18. How do you handle emergency changes in a CM environment?

    • Answer: Emergency changes require a streamlined, but controlled, process. This usually involves a fast-track approval process with a focus on immediate remediation and subsequent formal documentation of the change.

  19. What is infrastructure as code (IaC)?

    • Answer: IaC is the management of and provisioning of computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. Examples include Terraform and Ansible.

  20. How does CM support DevOps?
