When a disk-usage alert fires for a production VM, the team wants temporary files cleared automatically without waiting for an engineer to log in. Which setup handles this?
Show answer and explanation
Answer: D
Azure Monitor action groups can invoke an Automation runbook, directly or through a webhook, when an alert fires. The runbook can perform the cleanup, restart a service, or scale a resource without human involvement, and it can notify people afterward. Manual starts still require a person, email depends on someone reading it, and live metrics shows telemetry without executing corrective steps.
Why the other options are wrong
- A. A manually started runbook only runs when someone chooses to start it. That reintroduces the delay the team is trying to remove.
- B. Email reaches people, but the cleanup still waits for a human to read the message, log in, and act on the disk problem.
- C. The live metrics stream shows telemetry in near real time for diagnosis. It does not trigger any remediation when a threshold is crossed.
