AZ400-Q: route a production failure alert
A web application’s request-failure rate exceeds its agreed threshold for five minutes. The on-call team must be notified and the incident system must receive a webhook. Which Azure Monitor design best meets the requirement?
- A) Create a resource tag named
incident. - B) Grant the on-call team Reader access to the subscription.
- C) Write the failure rate to a markdown file after each deployment.
- D) Create an alert rule on the appropriate metric or log signal, define the threshold/window, and route it through an action group that contains the notification and webhook actions. ✓
Answer: D. An alert rule evaluates a signal and condition; an action group defines who or what is notified when the rule fires.
Why not the others: Tags and Reader access do not produce notifications. Markdown is documentation, not monitoring automation.
