You must create a monthly report of every new ARM resource deployment in your Azure subscription. Which service should you use to centrally gather and query deployment logs for the report?

Azure Log Analytics is the correct choice because it's a centralized logging service designed to collect, index, and query various types of log data, including Azure Resource Manager (ARM) deployment logs. You can use Kusto Query Language (KQL) within Log Analytics to filter and aggregate deployment events for your monthly report. Azure Analysis Services is a fully managed platform as a service (PaaS) that provides enterprise-grade data modeling capabilities, not a logging service. Azure Monitor metrics collects numerical data about resource performance, not detailed deployment logs. Azure Monitor action groups are used for notifications and automation based on alerts, not for log collection and querying.
