AZ-104 Question 258
Single answerYour company hosts several virtual machines in a resource group named ProductionRG. You want to be notified if any VM's CPU usage exceeds 80% for over five minutes. You also need to send both email and SMS alerts to your operations team, but only during business hours. Which Azure Monitor feature set best meets these requirements?
- A
Create a Metric alert rule for CPU usage, define an Action Group with email and SMS notifications, and create an Alert Processing Rule to automatically suppress the alert outside business hours
- B
Create an Activity Log alert on each VM, define multiple Action Groups for both email and SMS, and use Azure Logic Apps to suppress notifications after business hours
- C
Configure a Log Analytics alert for CPU usage, define an Action Group with only email notifications, and manually disable the alert after business hours each day
- D
Use Azure Monitor Autoscale rules to scale down after business hours, define an Action Group with email and SMS, and rely on quiet hours in Microsoft Teams to mute notifications
Show answer and explanation
Correct answer: A
Explanation
Metric alerts combined with an Action Group deliver the required notifications. An Alert Processing Rule can apply conditions to suppress alerts at specific times. This setup meets all the requirements for monitoring CPU usage, sending notifications, and restricting alerts to business hours.
- A. Correct.
This approach leverages Metric alert rules, an Action Group (email and SMS channels), and an Alert Processing Rule that automatically suppresses alert notifications outside specified time periods
- B. Incorrect.
Activity Log alerts detect Azure operations rather than continuous CPU metrics, and using Logic Apps would be more complex than using built-in Alert Processing Rules
- C. Incorrect.
Log Analytics alerts could capture performance data, but this option does not address automated suppression, and it only includes email notifications
- D. Incorrect.
Autoscale rules focus on resource scaling rather than alert suppression, and Teams quiet hours affect personal notifications, not the alert system itself
