Why is change control important?

• A. It ensures the fastest possible changes.
• B. It documents network topology.
• C. It ensures only security updates.
• D. It prevents unapproved or risky changes that could cause outages or security issues.

Answer: (D)

Change control is about governing changes to IT systems so that every modification goes through a formal, reviewed process. This means proposed changes are evaluated for risk, tested in a safe environment, approved by responsible stakeholders, scheduled to minimize impact, and backed up with a plan to roll back if something goes wrong. By inserting checks and oversight, change control reduces the chance that a risky or unapproved modification will cause outages, performance problems, or security gaps. That’s why this option is the best. It captures the core purpose: preventing unapproved or risky changes that could jeopardize availability or security. The other ideas miss the broader role of change control: it isn’t solely about speed, it isn’t just about documenting topology, and it isn’t limited to security updates. Change control applies to all meaningful changes, with governance, testing, and rollback planning to protect the environment.
