Step-by-step explanation:
The feature that identifies VMs with low utilization in Azure is Azure Advisor. Azure Advisor provides recommendations for optimizing your Azure resources, including virtual machines, based on best practices and utilization data. It analyzes performance, availability, security, and cost, and provides actionable insights to help you improve efficiency and reduce costs.
Azure Cost Management and Azure Cost Analysis are both tools that provide insights into resource costs and usage, but they do not specifically identify VMs with low utilization.
