AZ-900 Describe Azure management and governance Practice Question

A small company runs a noncritical development workload in Azure. The IT administrator wants to estimate the monthly cost of the planned virtual machines, storage accounts, and outbound bandwidth before creating anything, and needs the estimate to reflect a chosen Azure region and currency. Which Azure tool should the administrator use?

⚠ Common exam trap

Candidates often confuse the Azure Pricing calculator, which estimates costs before deployment, with Microsoft Cost Management, which reports and forecasts costs for resources that already exist.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Azure Pricing calculator

The Azure Pricing calculator is the pre-deployment estimation tool: you add services, set regions and quantities, and it returns projected monthly costs in the selected currency. Because nothing has been deployed, tools that analyze existing usage such as Microsoft Cost Management or Advisor are unsuitable. The calculator directly supports comparing regional pricing, which the administrator explicitly needs.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Azure Advisor

    Why it's wrong here

    Azure Advisor reviews already-deployed resources and surfaces recommendations to improve cost efficiency, reliability, security, and performance. It operates on existing subscriptions and resources and does not generate forward-looking price estimates for services you have not yet provisioned. Therefore it cannot help the administrator calculate the projected monthly cost of a planned development environment before creating it.

  • ✗

    Azure Migrate

    Why it's wrong here

    Azure Migrate discovers on-premises servers, assesses their readiness for Azure, and provides sizing and cost estimates for migration scenarios. It is built around inventorying existing on-premises infrastructure and does not model a brand-new set of Azure services chosen from scratch. Because the scenario involves planning new development resources rather than migrating discovered servers, Azure Migrate is not the appropriate tool.

  • ✗

    Microsoft Cost Management

    Why it's wrong here

    Microsoft Cost Management analyzes and forecasts spending for resources that already exist in an Azure subscription, providing cost analysis, budgets, and alerts. It depends on actual usage and billing data, so it cannot estimate a workload that has not been created. Since the administrator wants figures before deployment and for a not-yet-existing configuration, Cost Management cannot produce the needed estimate.

  • ✓

    Azure Pricing calculator

    Why this is correct

    The Azure Pricing calculator lets you configure services such as virtual machines, storage, and bandwidth, choose a region and currency, and view an estimated monthly cost before any resources exist. Because the workload has not been deployed yet, a pre-deployment estimation tool is required, and the calculator is designed precisely for modeling hypothetical configurations and comparing regional price differences without a subscription.
