AZ-900 Describe Azure management and governance Practice Question
A company's finance team wants to proactively monitor Azure spending and receive automated email notifications when costs reach 80% of a predefined monthly limit. They want to avoid manual cost tracking and set up alerts without custom scripting. Which Azure feature should they use?
⚠ Common exam trap
Candidates often confuse Azure Advisor cost recommendations (which suggest savings) with the alerting capability of Azure Cost Management budgets, or assume Azure Policy can enforce spending limits when it only governs resource configuration compliance.
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
✓
Create a budget in Azure Cost Management with an alert at 80% of the budget amount.
Azure Cost Management budgets allow you to set a spending limit and configure alert thresholds (e.g., 80%) that trigger automated email notifications when costs reach that percentage. This meets the finance team's requirement for proactive monitoring without custom scripting or manual tracking.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a budget in Azure Cost Management with an alert at 80% of the budget amount.
Why this is correct
Azure Cost Management budgets track actual and forecasted Azure spending against a defined monetary amount. Creating a budget with an alert threshold of 80% triggers an email or action-group notification when actual costs reach that level, enabling the finance team to proactively address overruns before the limit is exceeded. This is the native automated mechanism for ongoing spend monitoring.
- ✗
Use Azure Advisor cost recommendations and configure an alert on the recommendations.
Why it's wrong here
Azure Advisor provides recommendations to optimize costs (e.g., resizing underutilized VMs), but it does not send alerts based on a custom budget threshold. It is a different tool for cost optimization, not proactive budget monitoring.
When this WOULD be correct
If the question asked for a feature that provides cost optimization recommendations (e.g., rightsizing VMs, identifying idle resources) and the candidate needs to configure alerts on those recommendations, then Azure Advisor with alerts would be correct.
- ✗
Configure an Azure Policy with a deny effect to block any spending that exceeds the monthly limit.
Why it's wrong here
Azure Policy can enforce rules (e.g., deny deploying expensive VM SKUs) to prevent cost overruns, but it cannot send email alerts based on cumulative spending. It is a governance tool, not a cost monitoring and alerting tool.
When this WOULD be correct
When the question asks for a governance tool to enforce cost limits by preventing deployment of resources that would exceed a budget, such as 'block any new resource creation if the subscription cost exceeds $10,000 this month'.
- ✗
Use the Azure Pricing Calculator to estimate costs and set a manual reminder to check the Azure portal each month.
Why it's wrong here
The Azure Pricing Calculator is a static estimating tool used before deployment to predict potential costs based on configured inputs, such as VM size and expected usage. It does not connect to live billing data, cannot track cumulative monthly spending, and cannot send automated alerts. Relying on a manual calendar reminder to periodically check the portal does not provide the proactive, threshold-based notification required.
When this WOULD be correct
A question asking: 'Which tool should a company use to estimate the cost of running a proposed Azure workload before deployment?' would make the Azure Pricing Calculator 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.

Why this is correct
Azure Cost Management budgets track actual and forecasted Azure spending against a defined monetary amount.

✗Use Azure Advisor cost recommendations and configure an alert on the recommendations.Wrong answer — click to see why▾
Why this is wrong here
Azure Advisor cost recommendations provide suggestions to optimize existing spending, but they do not support proactive budget alerts or automated email notifications when spending reaches a threshold.
★ When this WOULD be the correct answer
If the question asked for a feature that provides cost optimization recommendations (e.g., rightsizing VMs, identifying idle resources) and the candidate needs to configure alerts on those recommendations, then Azure Advisor with alerts would be correct.
Why candidates choose this
Candidates may confuse cost recommendations with budget alerts, assuming Advisor can monitor spending thresholds, or they may think Advisor's alerting capability covers proactive cost limits.
✗Configure an Azure Policy with a deny effect to block any spending that exceeds the monthly limit.Wrong answer — click to see why▾
Why this is wrong here
Azure Policy with a deny effect blocks non-compliant resource creation or modification, but it cannot proactively monitor spending or send email alerts when costs reach a threshold. It is not designed for cost alerting.
★ When this WOULD be the correct answer
When the question asks for a governance tool to enforce cost limits by preventing deployment of resources that would exceed a budget, such as 'block any new resource creation if the subscription cost exceeds $10,000 this month'.
Why candidates choose this
Candidates may think Azure Policy can enforce spending limits because it can restrict resource types or regions, but they confuse cost enforcement with cost monitoring and alerting.
✗Use the Azure Pricing Calculator to estimate costs and set a manual reminder to check the Azure portal each month.Wrong answer — click to see why▾
Why this is wrong here
The Azure Pricing Calculator is for estimating future costs, not for proactive monitoring or automated alerts. It cannot trigger email notifications based on actual spending reaching a threshold.
★ When this WOULD be the correct answer
A question asking: 'Which tool should a company use to estimate the cost of running a proposed Azure workload before deployment?' would make the Azure Pricing Calculator the correct answer.
Why candidates choose this
Candidates may confuse cost estimation tools with cost monitoring tools, or think that setting a manual reminder is a valid alternative to automated alerts.
