Question 26

Having a backout plan when a patch fails describes effective change management procedures.

Effective change management procedures include planning for potential failures and having strategies in place to revert changes when necessary. A backout plan ensures that in the event of a failed patch, systems can be restored to their previous state, minimizing disruption.

A) Approving the change after a successful deployment

This option is incorrect as effective change management involves assessing and approving changes before deployment, not after. Approving changes post-deployment lacks proactive measures to prevent issues, which is essential for maintaining system integrity.

B) Having a backout plan when a patch fails

This option is correct because a backout plan is a critical component of effective change management. It ensures that organizations can quickly revert to a stable state if a patch does not perform as expected, thereby reducing the risk of extended downtime or system failure.

C) Using a spreadsheet for tracking changes

While using a spreadsheet for tracking changes may provide some level of organization, it is not considered an effective change management procedure. This method can lead to errors, lack of real-time updates, and difficulties in collaboration compared to more sophisticated change management tools.

D) Using an automatic change control bypass for security updates

This option is generally incorrect as bypassing change control processes, even for security updates, can introduce risks. Effective change management requires thorough review and approval processes to ensure that all changes, including security updates, are appropriately vetted to maintain system security and stability.

Conclusion

The correct answer, having a backout plan when a patch fails, is essential for effective change management as it prepares organizations for unforeseen issues. Options A, C, and D fail to prioritize proactive planning and risk management, which are vital for maintaining system reliability during changes. Option B stands out as it directly addresses the need for contingency measures in the change management process.
