Question 270
During follow-up testing at a corporate headquarters, the original fault was: A firewall configuration push fails with an unresolved variable reference after a shared snippet adds a new subnet parameter. Which measured result demonstrates recovery rather than an unrelated improvement?
Explanation
Correct Answer
The push job completes and the deployed rule uses the resolved branch-specific subnet. This evidence directly tests the intended corrective action: Populate the variable at the intended scope and rerun validation before the targeted push. It confirms the failure mechanism—Undefined configuration variables can prevent cloud configuration validation.—has been addressed in the actual affected flow.
Incorrect Answers
The previously disconnected firewall reports the new revision and matching test result. This would verify resolution of a different case: A firewall disconnected during a push and retained the previous policy, while its peers received the new change. It does not show that the reported issue was fixed or that its intended action—Populate the variable at the intended scope and rerun validation before the targeted push.—worked.
The branch validates with existing supported interfaces and receives the intended path policy. This would verify resolution of a different case: An engineer pushes a new SD-WAN rule that uses an interface unsupported or nonexistent on one branch model, causing validation errors. It does not show that the reported issue was fixed or that its intended action—Populate the variable at the intended scope and rerun validation before the targeted push.—worked.
Each intended firewall independently reports the approved revision and matching rule. This would verify resolution of a different case: A policy commit succeeds locally but the administrator assumes the same configuration was distributed to every firewall in the cloud-managed group. It does not show that the reported issue was fixed or that its intended action—Populate the variable at the intended scope and rerun validation before the targeted push.—worked.
