AZ-900 Describe Azure management and governance Practice Question

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 Cost Management + Billing

  Why it's wrong here

  Azure Cost Management + Billing is an operational tool for monitoring, analyzing, and optimizing costs after resources have been deployed. It provides budget tracking, anomaly alerts, and invoice reconciliation based on real consumption data. Because it requires active usage to generate insights, it cannot produce a forward-looking estimate for a solution that has not yet been built.

• ✗

  Azure Advisor

  Why it's wrong here

  Azure Advisor evaluates your existing Azure environment and provides personalized recommendations across cost, security, reliability, and performance. It inspects live resource configurations and usage patterns, then suggests actions like resizing underutilized VMs or eliminating idle resources. Since it works only on already-provisioned subscriptions, it cannot estimate the cost of a hypothetical new solution during the design phase.

• ✓

  Azure Pricing Calculator

  Why this is correct

  The Azure Pricing Calculator is specifically designed to estimate the monthly cost of a planned Azure solution. You select services, configure regions, tiers, and quantities, and it calculates an estimated bill based on current list prices. It supports hypothetical scenarios, letting you compare options before committing to deployment, making it the correct tool for pre-deployment cost estimation.

• ✗

  Azure TCO Calculator

  Why it's wrong here

  The Azure TCO Calculator compares the total cost of ownership of running a workload on-premises versus on Azure, including hardware, software, power, cooling, and labor. It is used for migration business cases, not for estimating the cost of a new, cloud-native solution. For directly estimating Azure service costs, the Pricing Calculator is the appropriate tool, so this option is incorrect.
