Which Azure tool provides a real-time dashboard for monitoring application health and performance?

Azure Monitor is the correct answer because it is a comprehensive monitoring solution for collecting, analyzing, and acting on telemetry from your Azure and on-premises environments. It provides real-time insights into application health, performance, and infrastructure, making it ideal for creating dashboards to visualize these metrics. Azure Cost Management focuses on tracking and optimizing cloud spending, not application health. Azure Sentinel is a Security Information and Event Management (SIEM) solution for threat detection and response. Azure Migrate assists with migrating workloads to Azure, not monitoring them post-migration.
