AZ-900 Describe Azure management and governance Practice Question
A company needs to track and optimize costs across multiple Azure subscriptions. They want to allocate budgets and receive notifications when spending exceeds forecasted amounts. Which Azure tool should they use?
⚠ Common exam trap
Many exam-takers confuse Azure Advisor's cost recommendations (which suggest ways to save money) with the actual cost management and alerting capabilities of Azure Cost Management, leading them to select Advisor instead.

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 is the correct tool because it provides native capabilities to track, analyze, and optimize cloud costs across multiple subscriptions. It allows you to set budgets, configure cost alerts, and receive notifications when actual or forecasted spending exceeds defined thresholds, directly addressing the requirement for budget allocation and proactive spending notifications.

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 is a personalized recommendation engine that evaluates resources against best practices for cost, security, reliability, and performance. While it provides cost optimization recommendations, such as right-sizing underutilized virtual machines or purchasing reserved instances, it does not set budgets, track actual spending over time, or send proactive alerts when costs exceed thresholds. Its role is advisory rather than a tracking and alerting mechanism.
When this WOULD be correct
Azure Advisor would be correct if the question asked: 'Which Azure tool provides recommendations to reduce costs by identifying idle resources and reserved instance opportunities?'
- ✓
Azure Cost Management
Why this is correct
Azure Cost Management is the native cloud financial management service for tracking, analyzing, and optimizing spend across Azure subscriptions. It provides a centralized view of costs, supports budget creation with alert thresholds, and includes cost analysis tools to identify spending trends and anomalies. As the umbrella service, it is the correct answer for tracking and optimizing costs.
- ✗
Azure Policy
Why it's wrong here
Azure Policy is a governance service that enforces rules on resource configurations, such as allowed regions, required tags, or compliance standards. It can help enforce cost-related governance like tagging for cost allocation, but it does not monitor actual spending, track usage costs, or send alerts based on budget thresholds. Therefore, it is not designed for cost tracking or optimization.
When this WOULD be correct
A company needs to enforce tagging requirements on all resources to ensure cost center attribution. Azure Policy can be used to require specific tags and deny deployment of resources without them.
- ✗
Azure Budgets
Why it's wrong here
Azure Budgets is a feature within Azure Cost Management that allows you to set spending limits and configure alert notifications when costs approach or exceed those limits. It does not exist as a fully independent service; rather, it is one component of the broader Azure Cost Management tool. Since the question asks for the tool that tracks and optimizes costs across subscriptions, Azure Cost Management—which encompasses budgets, cost analysis, and optimization guidance—is the more complete and correct option.
When this WOULD be correct
Azure Budgets would be correct if the question specifically asked: 'Which Azure feature allows you to set spending limits and receive alerts when costs exceed a threshold?' without requiring broader cost tracking or optimization across multiple subscriptions.
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 AdvisorWrong answer — click to see why▾
Why this is wrong here
Azure Advisor provides personalized recommendations for cost optimization, but it does not allow you to set budgets or receive notifications when spending exceeds forecasts. Cost Management is the tool designed for tracking, budgeting, and alerting on costs.
★ When this WOULD be the correct answer
Azure Advisor would be correct if the question asked: 'Which Azure tool provides recommendations to reduce costs by identifying idle resources and reserved instance opportunities?'
Why candidates choose this
Candidates may confuse Advisor's cost recommendations with the budgeting and alerting capabilities of Cost Management, assuming Advisor handles all cost-related tasks.
✗Azure PolicyWrong answer — click to see why▾
Why this is wrong here
Azure Policy is used to enforce compliance rules and governance across resources, not to track costs or set budgets with notifications. It does not provide cost tracking or budget alerting capabilities.
★ When this WOULD be the correct answer
A company needs to enforce tagging requirements on all resources to ensure cost center attribution. Azure Policy can be used to require specific tags and deny deployment of resources without them.
Why candidates choose this
Candidates may confuse Azure Policy's governance and compliance features with cost management, assuming it can also handle budgets and spending alerts.
✗Azure BudgetsWrong answer — click to see why▾
Why this is wrong here
Azure Budgets is a feature within Azure Cost Management, not a standalone tool. The question asks for the tool that tracks and optimizes costs across subscriptions, which is Azure Cost Management; Budgets alone cannot provide the full tracking and optimization capabilities.
★ When this WOULD be the correct answer
Azure Budgets would be correct if the question specifically asked: 'Which Azure feature allows you to set spending limits and receive alerts when costs exceed a threshold?' without requiring broader cost tracking or optimization across multiple subscriptions.
Why candidates choose this
Candidates may confuse Azure Budgets with Azure Cost Management because Budgets is a prominent part of cost management, leading them to select it as the tool rather than the overarching service.
