A company wants to ensure its Azure subscriptions remain compliant with internal standards. Which service provides compliance tracking?

Azure Policy is the correct answer because it allows you to define and enforce organizational standards and assess compliance at scale. You can create, assign, and manage policies that enforce rules and effects over your resources, ensuring they remain compliant with your company's internal standards. Azure Sentinel is a Security Information and Event Management (SIEM) solution, focused on threat detection and response, not compliance enforcement. Azure Monitor collects and analyzes telemetry data from your Azure resources, providing insights into their performance and health, but it doesn't enforce policies. Azure Advisor provides recommendations for optimizing your Azure deployments across various pillars like cost, security, and performance, but it doesn't enforce compliance.
