Question 850
At a distributed branch estate, a test team is validating a change after this incident: Policy Optimizer lists an unused Security rule, but an admin deletes it immediately without checking scheduled business traffic dependencies. What evidence most directly verifies the intended outcome?
Explanation
Correct Answer
A monitored disable period has no required business failures and documented owners accept removal. This evidence directly tests the intended corrective action: Verify hit evidence, maintenance-cycle use and owner approval, then stage a controlled disable/removal. It confirms the failure mechanism—Low recent hit counts do not prove a rule will never be needed for periodic applications.—has been addressed in the actual affected flow.
Incorrect Answers
Each batch has verified application outcomes and restored controls if a legitimate flow was impacted. This would verify resolution of a different case: A company uses Policy Optimizer findings to disable 50 rules at once without a rollback plan, disrupting regional month-end processing. It does not show that the reported issue was fixed or that its intended action—Verify hit evidence, maintenance-cycle use and owner approval, then stage a controlled disable/removal.—worked.
The rule's observed App-IDs and hit patterns are sufficiently complete to support a change decision. This would verify resolution of a different case: Policy Optimizer recommends removing an obsolete port-based rule, but the firewall's application identification data is incomplete due to missing log ingestion. It does not show that the reported issue was fixed or that its intended action—Verify hit evidence, maintenance-cycle use and owner approval, then stage a controlled disable/removal.—worked.
Sanctioned app flows pass with threat scanning and other apps remain blocked. This would verify resolution of a different case: An analyst optimizes a permissive rule by tightening App-ID but forgets to attach the intended prevention profiles to the replacement rule. It does not show that the reported issue was fixed or that its intended action—Verify hit evidence, maintenance-cycle use and owner approval, then stage a controlled disable/removal.—worked.
