AZ-900 Describe Azure management and governance Practice Question
A company wants to track spending across different projects. They have multiple Azure subscriptions and need to assign costs to specific departments based on resource usage. Which Azure feature enables them to view and analyze costs by resource tags?
⚠ Common exam trap
Watch out — candidates often confuse Azure Policy (which can enforce tagging) with Azure Cost Management (which analyzes costs by tags), but Policy does not provide cost visibility or analysis capabilities.
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
Azure Cost Management provides tools to view, analyze, and optimize cloud spending. It supports filtering and grouping costs by resource tags, enabling you to assign costs to specific departments or projects based on tagged resource usage.
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
Why this is correct
Azure Cost Management is the native FinOps service in Azure that ingests billing and usage data to provide historical cost analysis, create budgets, and visualize spend by tags, resources, or subscriptions. It enables cost allocation by grouping resources with user-defined tags, making it the correct tool for tracking spending across multiple projects via cost-by-tag reports.
- ✗
Azure Policy
Why it's wrong here
Azure Policy is a governance and compliance service that enforces rules on resources, such as requiring specific tags to be present on resources at creation time. It focuses on evaluating and remediating resource compliance — not on collecting, analyzing, or visualizing financial data — so it cannot show you how much money a project has spent across tagged resources.
When this WOULD be correct
A company needs to enforce that all resources in a subscription are tagged with a 'Department' tag. Azure Policy can be used to audit or apply a tag requirement, ensuring resources are tagged for cost allocation.
- ✗
Azure Advisor
Why it's wrong here
Azure Advisor is a personalized recommendation engine that analyzes your Azure configurations and usage patterns to suggest best practices, including cost optimization actions like resizing or deallocating underutilized VMs. However, it only provides prescriptive recommendations without exposing historical cost breakdowns or allowing you to filter spending by tags — advisory guidance, not a cost analytics tool.
When this WOULD be correct
A company wants to receive recommendations on how to reduce costs across their Azure subscriptions, such as identifying idle resources or right-sizing underutilized VMs. In that scenario, Azure Advisor would be the correct answer.
- ✗
Azure Monitor
Why it's wrong here
Azure Monitor is a telemetry platform that collects performance metrics, logs, and diagnostic data to monitor the health, availability, and performance of applications and infrastructure. It has no integration with billing or cost data, and while you might create custom logs or metrics, its core purpose is operational insight, not financial accounting or cost tracking.
When this WOULD be correct
A question asks: 'Which Azure service provides real-time monitoring and alerting on performance metrics and logs for applications and infrastructure?' In that context, Azure Monitor is 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 Cost ManagementCorrect answer▾
Why this is correct
Azure Cost Management is the native FinOps service in Azure that ingests billing and usage data to provide historical cost analysis, create budgets, and visualize spend by tags, resources, or subscriptions. It enables cost allocation by grouping resources with user-defined tags, making it the correct tool for tracking spending across multiple projects via cost-by-tag reports.
✗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 by resource tags. Cost analysis by tags is a feature of Azure Cost Management.
★ When this WOULD be the correct answer
A company needs to enforce that all resources in a subscription are tagged with a 'Department' tag. Azure Policy can be used to audit or apply a tag requirement, ensuring resources are tagged for cost allocation.
Why candidates choose this
Candidates may confuse Azure Policy's ability to enforce tagging rules with the actual cost analysis and reporting capabilities, mistakenly thinking Policy can also view and analyze costs.
✗Azure AdvisorWrong answer — click to see why▾
Why this is wrong here
Azure Advisor provides personalized recommendations for cost optimization, security, and reliability, but it does not enable viewing and analyzing costs by resource tags. Cost analysis by tags is a core function of Azure Cost Management.
★ When this WOULD be the correct answer
A company wants to receive recommendations on how to reduce costs across their Azure subscriptions, such as identifying idle resources or right-sizing underutilized VMs. In that scenario, Azure Advisor would be the correct answer.
Why candidates choose this
Candidates may confuse Azure Advisor's cost recommendations with the ability to analyze costs, or assume that 'Advisor' implies a cost management role due to its cost optimization recommendations.
✗Azure MonitorWrong answer — click to see why▾
Why this is wrong here
Azure Monitor is primarily for collecting and analyzing telemetry data (metrics, logs) from resources, not for tracking and analyzing cost data by resource tags.
★ When this WOULD be the correct answer
A question asks: 'Which Azure service provides real-time monitoring and alerting on performance metrics and logs for applications and infrastructure?' In that context, Azure Monitor is the correct answer.
Why candidates choose this
Candidates may confuse monitoring resource performance with monitoring costs, or think that Azure Monitor's data collection capabilities extend to cost tracking.
