AZ-900 Describe Azure management and governance Practice Question
A company has multiple Azure subscriptions for different departments. They want to receive budget alerts when spending in any subscription exceeds 80% of the allocated amount. Which Azure feature enables them to set up these alerts?
⚠ Common exam trap
Many exam-takers confuse Azure Monitor alerts (which handle performance and health metrics) with budget alerts, but budget alerts are exclusively managed through Azure Cost Management + Billing, not through Azure Monitor.
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
✓
Azure Cost Management + Billing budgets
Azure Cost Management + Billing budgets allow you to create budget alerts based on actual or forecasted costs. You can set a budget amount and configure alerts to trigger when costs reach a specified percentage (e.g., 80%) of that budget. This directly meets the requirement to receive alerts when spending in any subscription exceeds 80% of the allocated amount.
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 Cost Management + Billing budgets
Why this is correct
Azure Cost Management + Billing budgets are purpose-built to track spending against defined monetary thresholds at subscription, resource group, or management group scope. You can configure budget amounts, actual and forecasted cost threshold percentages, and trigger email alerts or automation via action groups when spending approaches or exceeds those levels. Because the service reads Azure billing and meter data, it directly fulfills the requirement to alert on subscription cost limits, unlike the general governance and telemetry tools in the other choices.
- ✗
Azure Advisor
Why it's wrong here
Azure Advisor is a personalized recommendation engine that analyzes resource configurations and usage to suggest cost optimizations, security fixes, reliability improvements, and performance tuning. While its cost recommendations can help reduce future spending, it does not track current subscription spend against a budget or emit threshold-based budget alerts. Therefore, Advisor is an advisory tool for optimizing costs, not an alerting mechanism for monitoring cost limits.
When this WOULD be correct
A company wants to receive recommendations on how to reduce costs across their Azure subscriptions. Azure Advisor would be the correct feature to provide cost optimization suggestions.
- ✗
Azure Monitor
Why it's wrong here
Azure Monitor is designed for operational telemetry from Azure resources and applications, capturing metrics like CPU utilization, memory, disk I/O, request rates, and log data via Log Analytics. It can alert on those metric or log conditions, but it has no native integration with Azure billing meters or accumulated monthly charges, so it cannot compare spending against a budget threshold. Use Cost Management budgets for cost-centric alerts, and reserve Azure Monitor for health, performance, and availability monitoring.
When this WOULD be correct
An exam question asking: 'Which Azure service should you use to receive alerts when a virtual machine's CPU utilization exceeds 80%?' would make Azure Monitor correct, as it can trigger alerts on performance metrics.
- ✗
Azure Policy
Why it's wrong here
Azure Policy applies compliance rules to resource properties through definitions and assignments, enforcing actions such as deny, audit, or modify during deployment and configuration drift. It evaluates JSON-based conditions about resource type, location, tags, or SKU, not the monetary value of resource consumption, so it cannot set spending thresholds or send cost-based alerts. Policy could indirectly support cost governance by requiring cost-allocation tags, but it never monitors actual bill amounts against a budget.
When this WOULD be correct
A company needs to ensure that all Azure resources are tagged with a cost center. Azure Policy can be used to enforce tagging rules and audit non-compliant resources.
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 recommendations for cost optimization, security, and reliability, but it does not support creating budget alerts based on spending thresholds. Budget alerts are a feature of Azure Cost Management + Billing.
★ When this WOULD be the correct answer
A company wants to receive recommendations on how to reduce costs across their Azure subscriptions. Azure Advisor would be the correct feature to provide cost optimization suggestions.
Why candidates choose this
Candidates may confuse Advisor's cost recommendations with the ability to set up budget alerts, assuming that any cost-related feature can handle alerts.
✗Azure MonitorWrong answer — click to see why▾
Why this is wrong here
Azure Monitor is for collecting and analyzing telemetry data (metrics, logs) from resources, not for setting up budget alerts based on spending thresholds. Budget alerts are a Cost Management feature.
★ When this WOULD be the correct answer
An exam question asking: 'Which Azure service should you use to receive alerts when a virtual machine's CPU utilization exceeds 80%?' would make Azure Monitor correct, as it can trigger alerts on performance metrics.
Why candidates choose this
Candidates may confuse Azure Monitor's alerting capabilities with budget alerts, assuming any alerting feature in Azure can handle financial thresholds, but Monitor lacks cost context.
✗Azure PolicyWrong answer — click to see why▾
Why this is wrong here
Azure Policy is used to enforce organizational standards and assess compliance, not to set up budget alerts based on spending thresholds.
★ When this WOULD be the correct answer
A company needs to ensure that all Azure resources are tagged with a cost center. Azure Policy can be used to enforce tagging rules and audit non-compliant resources.
Why candidates choose this
Candidates may confuse policy enforcement with cost management, thinking that policies can directly trigger alerts on spending.
