- A
Azure Policy with a Deny effect
Why wrong: Azure Policy enforces compliance rules on resources (e.g., requiring tags, restricting regions). It does not monitor costs or trigger actions based on budget thresholds.
- B
Azure Cost Management + Budgets with an action group configured to run a Runbook
Azure Cost Management + Budgets allows you to set spending limits and associate action groups. Action groups can trigger automated responses like running an Azure Automation Runbook, which can stop a VM.
- C
Azure Advisor cost recommendations
Why wrong: Azure Advisor provides recommendations to reduce costs (e.g., rightsizing underutilized VMs), but it does not automate actions based on budget thresholds.
- D
Azure Resource Graph queries with Azure Monitor alerts
Why wrong: Azure Resource Graph is for querying resources across subscriptions, and Azure Monitor alerts can send notifications. However, this combination does not natively integrate with budget data from Cost Management, and it would require significant custom logic to replicate budget-based automation.
Quick Answer
The answer is Azure Cost Management + Budgets with an action group configured to run a Runbook. This is correct because Azure Cost Management + Budgets allows you to define a monthly budget threshold, and when actual costs exceed 100% of that budget, you can trigger an action group that launches an Azure Automation Runbook—a script that can automatically stop a specific virtual machine to prevent further overspending. On the Microsoft Azure Fundamentals AZ-900 exam, this scenario tests your understanding of how budgets integrate with automation for cost control, often appearing as a question that distinguishes between simple alerting (like email at 80%) and automated remediation (like stopping a VM at 100%). A common trap is to choose just “Azure Budgets” or “Action Groups” alone, but the key is the combination of a budget triggering an action group that runs a Runbook. Memory tip: think “Budget + Action + Runbook = Auto-Stop.”
AZ-900 Describe Azure management and governance Practice Question
This AZ-900 practice question tests your understanding of describe azure management and governance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses multiple Azure subscriptions for development and production. The finance team wants to set a monthly budget of $1,000 for a specific dev subscription. When the actual cost reaches 80% of the budget, the team wants to receive an email alert. If the cost exceeds 100%, they want to automatically stop a specific virtual machine in that subscription to prevent overspending. Which Azure feature should the team use to automate the stopping of the VM when the budget is exceeded?

Correct answer & explanation
Azure Cost Management + Budgets with an action group configured to run a Runbook
Azure Cost Management + Budgets allows you to set a budget and configure alerts based on actual or forecasted cost thresholds. When the cost exceeds 100% of the budget, you can trigger an action group that runs an Azure Automation Runbook, which can be scripted to stop a specific virtual machine. This provides automated cost control without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Policy (which enforces compliance at resource creation) with Azure Cost Management + Budgets (which handles reactive cost alerts and automation), leading them to select Azure Policy despite its inability to stop running resources based on cost thresholds.
Detailed technical explanation
How to think about this question
Under the hood, Azure Budgets evaluate actual and forecasted costs against the defined budget amount at a set frequency (e.g., daily). When a threshold (e.g., 80% or 100%) is breached, it fires an alert that triggers an action group. The action group can invoke an Azure Automation Runbook via a webhook, which executes PowerShell or Python code to stop the VM using the Stop-AzVM cmdlet. This integration ensures automated cost governance without requiring manual monitoring or custom scripting outside of Azure.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
