Question 450
At a retail network, a test team is validating a change after this incident: A small firewall reaches its supported EDL capacity and lower-priority feeds are not fully loaded as a result. What evidence most directly verifies the intended outcome?
Explanation
Correct Answer
The critical IP indicators appear in effective entries and capacity-related System log errors clear. This evidence directly tests the intended corrective action: Reduce or prioritize approved feed contents and verify the device-specific entry limits and list order. It confirms the failure mechanism—EDL size and device limits can prevent complete ingestion even if files are valid.—has been addressed in the actual affected flow.
Incorrect Answers
The IP list parses without type errors and tested IP matches follow the intended block rule. This would verify resolution of a different case: An SOC provides an external IP threat feed containing URL strings and domain names inside a file configured as an IP external dynamic list. It does not show that the reported issue was fixed or that its intended action—Reduce or prioritize approved feed contents and verify the device-specific entry limits and list order.—worked.
Controlled listed test addresses hit the intended Security rule rather than an unrelated allow. This would verify resolution of a different case: A cloud firewall has a newly created dynamic block list but continues permitting known listed addresses because no Security rule references it. It does not show that the reported issue was fixed or that its intended action—Reduce or prioritize approved feed contents and verify the device-specific entry limits and list order.—worked.
The firewall reports a successful list refresh and sees the expected test entry. This would verify resolution of a different case: A threat feed is reachable from an analyst workstation but the managed firewall's EDL retrieval fails because its management egress cannot reach the host. It does not show that the reported issue was fixed or that its intended action—Reduce or prioritize approved feed contents and verify the device-specific entry limits and list order.—worked.
