Question 8
You use Azure DevOps to manage the build and deployment of an app named App1.
You have a release pipeline that deploys a virtual machine named VM1.
You plan to monitor the release pipeline by using Azure Monitor.
You need to create an alert to monitor the performance of VM1. The alert must be triggered when the average CPU usage exceeds 70 percent for five minutes.
The alert must calculate the average once every minute.
How should you configure the alert rule? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Correct answer: To work with this question, an Exam Simulator is required.
Explanation:
Box 1: 5 minutes The alert must calculate the average once every minute. Note: We [Microsoft] recommend choosing an Aggregation granularity (Period) that is larger than the Frequency of evaluation, to reduce the likelihood of missing the first evaluation of added time series Box 2: Static Box 3: Greater than Example, say you have an App Service plan for your website. You want to monitor CPU usage on multiple instances running your web site/app. You can do that using a metric alert rule as follows: Target resource: myAppServicePlan Metric: Percentage CPU Condition Type: Static Dimensions Instance = InstanceName1, InstanceName2 Time Aggregation: Average Period: Over the last 5 mins Frequency: 1 min Operator: GreaterThan Threshold: 70 Like before, this rule monitors if the average CPU usage for the last 5 minutes exceeds 70%.

Box 2: Static
Box 3: Greater than
Example, say you have an App Service plan for your website. You want to monitor CPU usage on multiple instances running your web site/app. You can do that using a metric alert rule as follows:
Target resource: myAppServicePlan
Metric: Percentage CPU
Condition Type: Static
Dimensions
Instance = InstanceName1, InstanceName2
Time Aggregation: Average
Period: Over the last 5 mins
Frequency: 1 min
Operator: GreaterThan
Threshold: 70
Like before, this rule monitors if the average CPU usage for the last 5 minutes exceeds 70%.
