AZ-104 Question 257
Select 2You are an Azure Administrator for a critical web application running on multiple Azure VMs. You need to be notified when the CPU utilization exceeds 90% for five consecutive minutes, but you also want to minimize alert fatigue by only sending notifications to a specific distribution group and suppressing repeated alerts for 30 minutes. Which steps should you take to meet these requirements?
- A
Create an action group that includes the distribution group email address as the sole recipient.
- B
Configure an alert processing rule that applies a 30-minute suppression window for repeated notifications.
- C
Enable the 'Autoscale' feature to handle CPU-based rule timing and automatically send notifications.
- D
Turn on 'Application Insights Smart Detection' to prevent repeated notifications for a CPU metric.
Show answer and explanation
Correct answers: A, B
Explanation
In Azure Monitor, you can create a metric alert rule to track high CPU usage, and then specify an action group for notifications. To reduce alert fatigue, use an alert processing rule to suppress repeated alerts for a defined time period. Autoscale and Application Insights Smart Detection have other purposes and do not address the requirement to limit alerts to a distribution group with a 30-minute suppression.
- A. Correct.
Creating an action group with the distribution group email address ensures only that group receives the alert notifications.
- B. Correct.
An alert processing rule can be used to set a suppression period, preventing repeat notifications for a specified duration.
- C. Incorrect.
Autoscale automatically scales resources based on metrics but does not handle notification suppression or routing to specific groups.
- D. Incorrect.
Application Insights Smart Detection is useful for anomaly detection but does not provide the required fine-grained control over CPU alert suppression and notification routing.
