AZ-900 Describe Azure management and governance Practice Question
A company wants to track and analyze Azure costs across multiple departments. They have tagged resources with 'Department' tags. Which tool should they use to view cost breakdowns by department?
⚠ Common exam trap
Many exam-takers confuse Azure Policy's ability to enforce tagging with the ability to analyze costs by those tags, but Azure Policy does not provide any cost reporting or analytics functionality.
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 Cost Management + Billing
Azure Cost Management + Billing is the correct tool because it provides native capabilities to analyze and visualize Azure spending, including the ability to filter and group costs by custom tags such as 'Department'. This allows the company to break down costs per department without needing additional configuration or external tools.
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 Policy
Why it's wrong here
Azure Policy applies organizational governance by enforcing rules and effects on resources, such as mandatory tags, allowed locations, or auditing compliance. These policies can indirectly support cost allocation by requiring consistent resource tags, but they do not capture, display, or analyze cost data themselves. Policy is a control and compliance tool, not a financial management dashboard.
When this WOULD be correct
A company needs to ensure that all resources are tagged with a 'Department' tag; Azure Policy can be used to enforce tagging rules and audit resources that lack the required tag.
- ✓
Azure Cost Management + Billing
Why this is correct
Azure Cost Management + Billing is the native tool for tracking, analyzing, and reporting Azure spending. It supports grouping by resource tags, which lets an organization allocate costs to specific departments, projects, or owners. It also offers budgets, cost anomaly alerts, scheduled exports, and integration with Power BI for deeper financial analysis.
- ✗
Azure Advisor
Why it's wrong here
Azure Advisor assesses deployed resources against best practices and provides recommendations for reliability, security, performance, and cost optimization. Its 'cost' section suggests actions like rightsizing idle VMs or purchasing reserved instances, but it does not provide cost breakdowns or actual spending by department. Therefore, it is advisory in nature and cannot track historical usage patterns across cost centers.
When this WOULD be correct
A company wants to receive personalized recommendations to reduce Azure spending and improve resource efficiency. In that scenario, Azure Advisor would be the correct tool to use.
- ✗
Azure Service Health
Why it's wrong here
Azure Service Health delivers personalized status information about incidents, planned maintenance, and health advisories affecting the Azure platform and regional services. It is exclusively focused on operational health and has no access to billing, invoices, or cost analytics. While useful for knowing when infrastructure is unhealthy, it does not help identify how much any department spends on Azure.
When this WOULD be correct
A question asking which tool provides personalized guidance on Azure service issues, planned maintenance, and health advisories for your subscriptions would have Azure Service Health as the correct answer.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-900 exam frequently reuses these exact scenarios with slightly different constraints.

✗Azure PolicyWrong answer — click to see why▾
Why this is wrong here
Azure Policy is used to enforce organizational standards and assess compliance, not to track or analyze costs. It cannot provide cost breakdowns by department tags.
★ When this WOULD be the correct answer
A company needs to ensure that all resources are tagged with a 'Department' tag; Azure Policy can be used to enforce tagging rules and audit resources that lack the required tag.
Why candidates choose this
Candidates may confuse Azure Policy's ability to evaluate tags with cost management, thinking that policy-driven tagging automatically enables cost analysis.
✗Azure AdvisorWrong answer — click to see why▾
Why this is wrong here
Azure Advisor provides recommendations for cost optimization, security, and performance, but it does not offer cost tracking or breakdowns by tags. Cost breakdowns by department require Azure Cost Management + Billing.
★ When this WOULD be the correct answer
A company wants to receive personalized recommendations to reduce Azure spending and improve resource efficiency. In that scenario, Azure Advisor would be the correct tool to use.
Why candidates choose this
Candidates may confuse cost optimization recommendations (Advisor) with actual cost tracking and analysis, assuming Advisor can provide cost breakdowns by tag.
✗Azure Service HealthWrong answer — click to see why▾
Why this is wrong here
Azure Service Health provides information about Azure service outages and planned maintenance, not cost tracking or analysis by department tags.
★ When this WOULD be the correct answer
A question asking which tool provides personalized guidance on Azure service issues, planned maintenance, and health advisories for your subscriptions would have Azure Service Health as the correct answer.
Why candidates choose this
Candidates may confuse 'health' with 'cost health' or think Service Health includes cost-related alerts, but it is solely focused on service availability and incidents.
