During a scheduled maintenance window, a senior administrator applies a new security configuration baseline to a core enterprise gateway. Immediately after applying the change, automated monitoring indicates that key database servers have lost network reachability due to an unintended blocking rule. Which of the following is the immediate next step the administrator should take according to standard change management procedures?
- Execute the documented rollback plan to return the core gateway to its pre-change functional baseline configuration.Answer
- BPerform ad-hoc command-line interface edits on the live production gateway to troubleshoot and patch the missing rule.
- CModify the default implicit deny rule at the bottom of the ACL to permit all traffic until the next maintenance window.
- DConvene an emergency Change Advisory Board (CAB) meeting while leaving the degraded gateway state active to request policy exemption.
Answer
The immediate next step is to execute the documented rollback plan to return the core gateway to its pre-change functional baseline configuration.
Executing the documented rollback plan is the required response when a change fails post-implementation testing. Reverting to the pre-change configuration baseline restores production service immediately without introducing unvetted configuration drift.
