What is the primary purpose of change management in a network operations context?

• A. It governs modifications to minimize risk; methods include documented requests, risk assessments, testing, approvals, change windows, and post-change reviews.
• B. It reduces the need for testing by using automated rollbacks.
• C. It only applies to software changes, not hardware.
• D. It delays all changes until a formal quarterly cycle.

Answer: (A)

Change management in network operations is about controlling modifications to the environment to minimize risk. It uses a formal process: submitting a change request, performing risk assessments, validating through testing, obtaining approvals, scheduling within a change window, and conducting a post-change review. This sequence provides visibility, accountability, and coordination across teams, reducing the chance of unintended outages and enabling rollback if something goes wrong. The change window minimizes impact to users by restricting changes to times with lower activity, and post-change reviews capture lessons learned for future improvements. The other ideas don’t fit as well: relying on automated rollbacks to avoid testing misses the proactive risk reduction that testing and approvals provide; testing is still crucial, and rollbacks are a safety net, not the primary purpose. Change management applies to hardware and configurations as well as software, not just software. Delaying all changes until a quarterly cycle is too rigid; control and scheduling should support timely, approved changes, including emergency ones, rather than immobilizing the environment.
