AZ-900 Describe Azure management and governance Practice Question
What is the purpose of Azure Cost Management budgets?
⚠ Common exam trap
Test-takers frequently confuse budget alerts with automated cost-saving actions, assuming budgets can directly stop or deallocate resources, when in fact budgets only provide notifications and require external automation for enforcement.

Correct answer & explanation
✓
To set spending thresholds and receive alerts when approaching those limits
Azure Cost Management budgets allow you to set spending thresholds (e.g., monthly, quarterly) and configure alerts that notify you via email or action groups when costs reach a certain percentage of the budget (e.g., 50%, 90%, 100%). This enables proactive cost governance without automatically stopping resources, which is not a built-in budget action.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To automatically stop resources when spending exceeds a defined limit
Why it's wrong here
Budget alerts are notification-only; they do not natively execute any automated response such as stopping or deallocating resources. To automatically shut down resources when a budget threshold is crossed, you must build an external automation flow—for example, an Azure Automation runbook or a Logic App triggered by the alert signal. The budget itself neither enforces the limit nor performs any action on Azure resources.
- ✓
To set spending thresholds and receive alerts when approaching those limits
Why this is correct
Azure budgets let you set a cost or usage threshold and then configure alerts on actual or forecasted spend reaching a defined percentage of that threshold (for example, 50%, 90%, or 100%). These alerts integrate with Azure Action Groups to send email, SMS, or webhook notifications. This is exactly what the correct answer describes: establishing spending limits and being notified as you approach them.
- ✗
To transfer unused budget from one resource to another
Why it's wrong here
An Azure budget is a monitoring threshold, not a pool of funds that can be moved between resources. Each budget is scoped to a subscription, resource group, or management group, and it tracks actual and forecasted spending against that scope; Azure Cost Management does not provide any capability to transfer unused budget amounts between resources. The purpose of a budget is to trigger alerts when spend approaches a limit, not to manage fund allocation.
- ✗
To reserve compute capacity for future use
Why it's wrong here
Azure budgets are a cost management feature that tracks spending against defined thresholds and sends alerts; they do not reserve compute capacity. Reserving compute capacity is accomplished through Azure Reserved Instances or capacity reservation groups, which commit to a specific VM SKU and region for a one- or three-year term. Budgets have no role in capacity allocation, making this option incorrect.
