Why is deleting alert rules before a change a worse practice than scheduling a maintenance window?
Select an answer to reveal the explanation.
Short Explanation
The gap is silent. A maintenance window ends on its own; a deleted rule waits for someone to remember it.
Full Explanation
The correct answer is the option saying recreating rules is a manual step that can be forgotten or done inconsistently, leaving the service without alerting after the change. Deletion moves the restore step into human memory, and the failure is invisible: absent alerts look like a healthy system until something goes wrong unobserved. The option saying deleted rules cannot be recreated with the same name is wrong because they can be recreated with any name; the risk is that they are not recreated at all. The option saying deletion also deletes evaluated telemetry is wrong because alert configuration and stored telemetry are independent. The option saying rules can only be deleted during an active maintenance window is wrong because deletion is not gated on a maintenance window. For the exam, prefer time-bound suppression over destructive configuration changes.
