A government agency needs a report of all resources with public IP addresses across subscriptions. Which service should they use?

Azure Resource Graph is the correct choice because it allows for efficient exploration of Azure resources at scale across multiple subscriptions. It uses Kusto Query Language (KQL) to query resource properties, enabling you to quickly find resources like those with public IP addresses. Azure Monitor collects and analyzes telemetry data but doesn't primarily focus on resource inventory. Azure Security Center (now Microsoft Defender for Cloud) focuses on security posture management and threat protection. Azure Advisor provides recommendations for optimizing Azure deployments, not for querying resource configurations directly.
