How to Set Azure Budgets and Receive Alerts at Spending Thresholds
A company has multiple Azure subscriptions, each belonging to a different department. The finance department wants to set spending limits per subscription and receive automated email notifications whenever actual spending reaches 80% of the allocated budget. Which Azure feature should they configure?
Quick Answer
The answer is Azure Budgets, the correct feature for setting spending limits per subscription and triggering automated email alerts when spending hits a specified threshold like 80%. Azure Budgets allows you to define a cost budget at the subscription or resource group level, then configure alert rules that fire when actual or forecasted costs exceed a percentage of that budget—directly meeting the finance department’s need for per-subscription limits and proactive notifications. On the AZ-900 exam, this scenario tests your understanding of cost management tools; a common trap is confusing Azure Budgets with Azure Cost Management views or Azure Policy, but remember that budgets are specifically for setting thresholds and alerts, not for enforcing compliance. A helpful memory tip: think of “Budget Alerts” as your financial tripwire—set the 80% mark, and Azure sends the email automatically.
⚠ Common exam trap
Watch out — candidates often confuse Azure Policy (which enforces compliance rules) with Azure Budgets (which monitors and alerts on spending), as both involve 'rules' but serve fundamentally different purposes—Policy does not track costs or send spending alerts.

Correct answer & explanation
✓
Azure Budgets
Azure Budgets is the correct feature because it allows you to set spending limits (budgets) on Azure subscriptions or resource groups and configure alerts that trigger automated email notifications when actual spending reaches a specified threshold, such as 80% of the allocated budget. This directly meets the finance department's requirement for per-subscription spending limits and proactive notifications.
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 is used to enforce organizational standards and assess compliance for resource configurations, such as restricting resource locations or requiring tags. It does not provide cost monitoring or budget alerts.
When this WOULD be correct
An organization needs to ensure that all deployed virtual machines in a subscription are tagged with a cost center. Azure Policy can be used to audit or enforce the presence of required tags.
- ✓
Azure Budgets
Why this is correct
Azure Budgets, a feature of Azure Cost Management, enables you to set spending limits on subscriptions, resource groups, or management groups. You can configure alerts that trigger when spending reaches a specified percentage of the budget, such as 80%, and send email notifications.
- ✗
Azure Blueprints
Why it's wrong here
Azure Blueprints orchestrate the deployment of resource groups, policies, role assignments, and ARM templates to create a governable environment. While they can include policies, they do not directly monitor spending or send budget alerts.
When this WOULD be correct
A company needs to deploy a standardized set of Azure resources (e.g., VMs, databases) with built-in RBAC and policy assignments across multiple subscriptions for compliance. Azure Blueprints would be the correct answer.
- ✗
Azure Resource Graph
Why it's wrong here
Azure Resource Graph is a powerful query language that allows you to explore and discover Azure resources across subscriptions. It is used for resource inventory and governance queries, but it does not provide budget monitoring or alerting capabilities.
When this WOULD be correct
An administrator needs to quickly find all virtual machines in a subscription that are tagged with 'Environment: Production' across multiple resource groups. Azure Resource Graph would be the correct tool to run such a cross-resource query.
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 BudgetsCorrect answer▾
Why this is correct
Azure Budgets, a feature of Azure Cost Management, enables you to set spending limits on subscriptions, resource groups, or management groups. You can configure alerts that trigger when spending reaches a specified percentage of the budget, such as 80%, and send email notifications.
✗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 set spending limits or trigger notifications based on budget thresholds.
★ When this WOULD be the correct answer
An organization needs to ensure that all deployed virtual machines in a subscription are tagged with a cost center. Azure Policy can be used to audit or enforce the presence of required tags.
Why candidates choose this
Candidates may confuse Azure Policy's governance capabilities with cost management features, assuming it can enforce budget limits or send alerts.
✗Azure BlueprintsWrong answer — click to see why▾
Why this is wrong here
Azure Blueprints is used to define a repeatable set of Azure resources and policies for environment compliance, not for setting spending limits or budget alerts.
★ When this WOULD be the correct answer
A company needs to deploy a standardized set of Azure resources (e.g., VMs, databases) with built-in RBAC and policy assignments across multiple subscriptions for compliance. Azure Blueprints would be the correct answer.
Why candidates choose this
Candidates may confuse Blueprints with Budgets because both involve planning and governance, but Blueprints focuses on resource orchestration, not cost tracking.
✗Azure Resource GraphWrong answer — click to see why▾
Why this is wrong here
Azure Resource Graph is a query tool for exploring and discovering resources across subscriptions, not for setting spending limits or budget alerts.
★ When this WOULD be the correct answer
An administrator needs to quickly find all virtual machines in a subscription that are tagged with 'Environment: Production' across multiple resource groups. Azure Resource Graph would be the correct tool to run such a cross-resource query.
Why candidates choose this
Candidates may confuse Azure Resource Graph's ability to query across subscriptions with the ability to enforce or monitor budgets across them.

Variation 1. A company's finance team uses Azure Cost Management + Billing to monitor cloud spending. They want to configure a rule that sends an email notification to the finance team's distribution list when the monthly cost for resources tagged with Department=Marketing exceeds $10,000. Which Azure Cost Management feature should they configure?
medium- ✓ A.Budget
- B.Invoice
- C.Cost analysis
- D.Recommendations
Why A: Azure Budgets allow you to set cost or usage thresholds and configure alerts that trigger when spending reaches a specified percentage of the budget. In this scenario, the finance team can create a budget with a $10,000 threshold for the Department=Marketing tag, and configure an alert rule to send an email notification to the distribution list when costs exceed that amount.
