A technician recently received a written warning for causing a system-wide outage. The outage was a result of an unattributed patch being manually pushed during production hours. Which of the following could have most likely prevented the technical from receiving the warning?

While validating a rollback plan is an important practice to ensure that systems can revert to a stable state after an update, it does not directly address the issue of improperly pushing a patch during production hours. Without following corporate procedures, even a validated rollback plan would not prevent the initial outage, since the patch deployment itself was against protocol.

Documenting findings is crucial for post-incident analysis and future reference, but it does not prevent incidents from occurring in the first place. Even if the technician documented the situation afterward, it would not mitigate the consequences of the outage that resulted from the unauthorized patch deployment.

Establishing a plan of action can be beneficial for future incidents, but in this case, it wouldn't have prevented the warning for the past incident. A plan of action does not replace the necessity of following existing corporate procedures when executing actions that impact production systems.
