Question 880
Before a monitored change is approved, the SOC finds: A playbook triggered by a security event adds a firewall block that generates another matching event and retriggers itself repeatedly. Which acceptance check confirms that the requirement is satisfied?
Explanation
Correct Answer
This directly verifies playbook loops caused by response logs: One controlled detection initiates one appropriate response sequence without a self-amplifying loop. The linked remediation is: Narrow the trigger to primary detections and exclude playbook-generated response events using supported filters. A result from an unrelated SOC function does not prove this requirement.
Incorrect Answers
A test from tenant A can affect only its approved device and cannot alter tenant B's firewall. This is a different failure mechanism from the current case, which concerns one controlled detection initiates one appropriate response sequence without a self-amplifying loop.
This option instead describes a simulated ambiguous IOC produces a review item rather than an automatic critical-server outage. Testing that independent mechanism would not show whether the reported fault has been resolved.
The indicator is demonstrably blocked on the intended gateway and the incident links to proof of enforcement. The stem describes a playbook triggered by a security event adds a firewall block that generates another matching event and retriggers itself repeatedly, so this explanation does not account for the observations.
