HOTSPOT

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.

Correct Answer:

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%. Aggregation granularity

You use an Azure pipeline to build a .NET app that has NuGet dependencies.

You need to ensure that the pipeline caches required NuGet packages.

How should you configure the pipeline? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.
