Azure Cost Management is a comprehensive tool that provides visibility into costs and usage across various scopes.

1. It supports analysis at high-level containers like management groups, allowing for an aggregated view of costs across multiple subscriptions.
2. It also supports granular analysis at the resource group and individual resource level, which is a fundamental feature of the Cost Analysis tool.
3. The third statement is correct because "usage" in this context refers to billable usage quantities (e.g., "Compute Hours," "Data Transfer"), not real-time performance metrics. Azure Cost Management tracks and displays this consumption data, allowing you to analyze the quantity of services used over time. This data is available for at least the last 13 months.

Microsoft Learn. (2024). Overview of Cost Management. In: "Azure Cost Management documentation." This document states that Cost Management is "available from every subscription, resource group, and management group" and helps you "track usage, monitor expenses, identify cost anomalies, and forecast your expenditures."

Microsoft Learn. (2024). Understand and work with scopes. In: "Azure Cost Management documentation." This page explicitly lists management groups, subscriptions, and resource groups as the scopes at which you can apply permissions and view cost data.

Microsoft Learn. (2024). View and download Azure usage and charges. In: "Azure Cost Management documentation." This document details how to download "Usage Details" from the "Usage + charges" page within Cost Management + Billing. This report provides granular details on consumption.

Microsoft Learn. (2024). Understanding Azure virtual machine usage. In: "Azure Virtual Machines documentation." This document explains the specific billing meters for VMs, such as "Meter Name" (e.g., "Compute Hours"), "Unit" (e.g., "Hours"), and "Consumed" (the quantity used). This is the "usage" data that is fed into Azure Cost Management for analysis.

Microsoft Learn. (2024). Understand Cost Management data. In: "Azure Cost Management documentation." Section: "Cost and usage data updates and retention." This document confirms that "Summarized data in Cost Analysis is only available for the last 13 months," which satisfies the "last three months" requirement.
