Identify Underutilized Virtual Machines for Service Tier Optimization

D

The correct answer is D. Advisor.

Advisor is a service in Azure that provides personalized recommendations to optimize and improve the performance, security, and reliability of your Azure resources. It analyzes your resource configuration and usage telemetry data to provide best practices and recommendations on cost optimization, security, high availability, and performance.

In this scenario, you have 100 Azure virtual machines and you need to identify underutilized virtual machines that can have their service tier changed to a less expensive offering. Advisor can provide you with recommendations to optimize your virtual machines and reduce their costs by identifying underutilized resources and suggesting ways to optimize their configuration.

To find the recommendations related to virtual machine underutilization, you can follow these steps:

1. Go to the Azure portal and search for "Advisor" in the search bar.
2. Select "Advisor" from the results and open the Advisor blade.
3. In the left-hand menu, click on "Cost" and then select "Cost optimization".
4. Here you will see a list of recommendations related to cost optimization. Look for the recommendations related to virtual machine underutilization. For example, you might see a recommendation to change the size of underutilized virtual machines to a smaller size or to change the tier of the virtual machine to a less expensive offering.

You can also use the "Advisor Score" feature to see an overall score for your Azure resources based on their compliance with Azure best practices. The score can help you identify areas where you can optimize your resources and reduce costs.

In conclusion, Advisor is the blade you should use to quickly identify underutilized virtual machines that can have their service tier changed to a less expensive offering. It provides personalized recommendations to optimize your resources and reduce costs.
