AZ-900 Describe Azure management and governance Practice Question
Which Azure pricing calculator helps you estimate monthly costs for Azure services before deploying them?
⚠ Common exam trap
Watch out — candidates often confuse the Azure Pricing Calculator (pre-deployment estimation) with the Azure TCO Calculator (on-premises vs. cloud comparison) or Azure Cost Management (post-deployment monitoring), as all three involve cost but serve different lifecycle stages.

Correct answer & explanation
✓
Azure Pricing Calculator
The Azure Pricing Calculator is the correct tool for estimating monthly costs of Azure services before deployment. It allows you to configure services (e.g., VMs, storage, databases) by specifying parameters like region, tier, and usage hours, then generates a detailed cost estimate. This pre-deployment estimation is its primary purpose, distinguishing it from post-deployment cost analysis tools.

Azure TCO Calculator
Why it's wrong here
The Azure TCO Calculator is designed to model the total cost of ownership comparison between running a workload on-premises versus in Azure, requiring inputs like server counts, storage, and network usage. It answers the question 'Is migrating worth it?' by factoring in hardware, electricity, and IT labor, not 'What will this exact Azure service configuration cost?'. Since the user needs a per-service monthly price estimate for a planned Azure-only solution, the TCO Calculator is the wrong tool because it estimates savings from migration, not the actual line-item cost of individual Azure services.

Azure Pricing Calculator
Why this is correct
The Azure Pricing Calculator is an interactive pre-deployment tool that lets you select specific Azure services, configure details such as region, tier, instance size, and expected usage, then calculates the estimated monthly cost. It provides a detailed cost breakdown per service, supports saving and sharing estimates, and can incorporate Azure Hybrid Benefit or reserved capacity to refine budget forecasts. This directly satisfies the requirement to estimate monthly costs for a planned Azure service before any deployment, making it the correct choice.
- ✗
Azure Cost Management
Why it's wrong here
Azure Cost Management is an operational tool that monitors and analyzes actual Azure spending after resources have been deployed, using features like budgets, alerts, and cost analysis to track usage against plan. It can show historical trends, forecast future spend based on past usage, and identify cost anomalies, but it cannot produce a pre-deployment estimate for a specific configuration of services that have not been created yet. Because the user asks for an estimate before deployment, Cost Management addresses the wrong phase of the cloud lifecycle.
- ✗
Azure Advisor
Why it's wrong here
Azure Advisor is a free, built-in service that continuously evaluates your existing Azure resources and provides personalized recommendations for high availability, security, performance, and cost optimization. Its cost recommendations, such as right-sizing underutilized VMs or eliminating idle resources, are based on live usage patterns of resources already deployed. Advisor has no mechanism to calculate the pre-deployment cost of a hypothetical service configuration, so it cannot be used to estimate monthly costs for a planned service.
