Which service compares a company's cloud usage to industry-standard best practices?

Azure Advisor is the correct answer because it provides personalized recommendations to optimize your Azure deployments. It analyzes your resource configuration and usage telemetry and then recommends solutions to improve high availability, security, performance, operational excellence, and cost. These recommendations are based on industry best practices and can help you align your cloud usage with established standards. Azure Monitor collects and analyzes telemetry from your Azure resources, but it doesn't directly compare usage to best practices; it's more for operational insights and alerting. Azure Service Health provides a personalized view of the health of your Azure services and regions, informing you about outages or planned maintenance, not best practice comparisons. Application Insights, a feature within Azure Monitor, focuses on application performance management and monitoring, not overall cloud best practice adherence.
