Question 400
After a corrective change at a hospital campus, the team documents: A central rule was deployed to the wrong group and blocks business traffic, but the admin begins a second untested edit instead of a controlled restore. Which repeatable control BEST prevents a recurrence?
Explanation
Correct Answer
Maintain tested configuration recovery points and rollout stop conditions. This control reduces recurrence of the documented mechanism: Unstructured emergency edits can extend a production outage after a bad push. It creates a repeatable check around the needed response: Use the supported restore/revert procedure for the known good configuration and verify recovery.
Incorrect Answers
Test log profile dependencies on pilot firewalls before fleet distribution. That safeguard addresses another potential failure: A log forwarding profile with a malformed destination reference passes initial editing but fails target validation on push. It is not the most targeted recurring control for the described cause: Unstructured emergency edits can extend a production outage after a bad push.
Track offline devices and enforce deployment reconciliation after maintenance. That safeguard addresses another potential failure: A firewall disconnected during a push and retained the previous policy, while its peers received the new change. It is not the most targeted recurring control for the described cause: Unstructured emergency edits can extend a production outage after a bad push.
Document target and authority checks for device-local versus central commits. That safeguard addresses another potential failure: A policy commit succeeds locally but the administrator assumes the same configuration was distributed to every firewall in the cloud-managed group. It is not the most targeted recurring control for the described cause: Unstructured emergency edits can extend a production outage after a bad push.
