AZ-900 Describe Azure management and governance Practice Question
A company wants to receive proactive recommendations to reduce Azure costs, improve security, and increase reliability. They want a single dashboard that provides best practices for their deployed resources. Which Azure service should they use?
⚠ Common exam trap
A common mix-up: candidates confuse Azure Advisor with Azure Monitor, thinking monitoring alone provides proactive recommendations, but Monitor only surfaces raw data and alerts, not curated, actionable best-practice guidance.
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 Advisor
Azure Advisor is the correct service because it provides a personalized, consolidated dashboard of best-practice recommendations across cost optimization, security, reliability, operational excellence, and performance. It analyzes your deployed resources and proactively suggests actions such as resizing underutilized VMs, enabling geo-redundancy, or applying security policies, directly matching the company's need for proactive, single-pane-of-guidance.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Advisor
Why this is correct
Azure Advisor is the correct answer because it is a free, built-in service that provides personalized best-practice recommendations across five pillars: cost, security, reliability, performance, and operational excellence. By analyzing your resource configuration and usage patterns, Advisor proactively identifies actions such as right-sizing underutilized virtual machines, purchasing reserved instances, or deleting idle resources. These recommendations help you reduce costs and improve overall workload health in a single dashboard.
- ✗
Azure Cost Management + Billing
Why it's wrong here
Azure Cost Management + Billing is incorrect because its primary role is financial management, including cost analysis, budgeting, invoicing, and payment reviews. While it does surface some cost optimization suggestions—such as anomaly alerts or purchase advice for reserved instances—its scope is limited to cost and cannot cover security, reliability, or performance recommendations. Azure Advisor, by contrast, delivers a holistic set of proactive best practices across all pillars, making it the correct service for reducing costs and improving overall Azure health.
When this WOULD be correct
A company wants to analyze and optimize their cloud spending, set budgets, and generate cost reports. They need a tool to track spending patterns and receive cost-related alerts.
- ✗
Azure Monitor
Why it's wrong here
Azure Monitor is incorrect because it is a telemetry collection and analysis service that gathers metrics, logs, and traces from Azure resources to provide observability into performance, availability, and health. It enables real-time alerts, dashboarding, and diagnostics, but it is fundamentally reactive—it tells you what is happening or has happened, not what you should proactively change. Monitor does not generate recommendations for cost reduction; those come from Advisor's proactive analysis of resource utilization and configuration.
When this WOULD be correct
Azure Monitor would be correct if the question asked for a service to collect and analyze telemetry data, set up alerts, or create dashboards for performance and health metrics of Azure resources, such as tracking CPU usage or application errors.
- ✗
Azure Resource Graph
Why it's wrong here
Azure Resource Graph is incorrect because it is a service designed for efficient resource discovery and querying at scale using Kusto Query Language. It allows you to power inventory, governance, and compliance scenarios by searching across subscriptions and resource properties, but it does not analyze configurations or generate any advisory recommendations. Resource Graph simply returns the data you ask for; it does not provide proactive cost-saving or optimization guidance.
When this WOULD be correct
An exam question asking 'Which service allows you to query and explore Azure resources across multiple subscriptions using KQL?' would make Azure Resource Graph 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.

✗Azure Cost Management + BillingWrong answer — click to see why▾
Why this is wrong here
Azure Cost Management + Billing focuses on cost analysis and budgeting, but does not provide proactive recommendations for security or reliability improvements across deployed resources.
★ When this WOULD be the correct answer
A company wants to analyze and optimize their cloud spending, set budgets, and generate cost reports. They need a tool to track spending patterns and receive cost-related alerts.
Why candidates choose this
Candidates may think cost management includes broader recommendations, or they confuse the cost-related features of Advisor with Cost Management's budgeting capabilities.
✗Azure MonitorWrong answer — click to see why▾
Why this is wrong here
Azure Monitor provides monitoring and diagnostics for resources, but it does not deliver proactive recommendations for cost, security, or reliability best practices. The question specifically asks for a single dashboard with best-practice recommendations, which is the function of Azure Advisor.
★ When this WOULD be the correct answer
Azure Monitor would be correct if the question asked for a service to collect and analyze telemetry data, set up alerts, or create dashboards for performance and health metrics of Azure resources, such as tracking CPU usage or application errors.
Why candidates choose this
Candidates may confuse Azure Monitor's dashboard and alerting capabilities with the advisory recommendations of Azure Advisor, assuming that monitoring includes proactive best-practice guidance.
✗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 a dashboard that provides proactive recommendations for cost, security, or reliability.
★ When this WOULD be the correct answer
An exam question asking 'Which service allows you to query and explore Azure resources across multiple subscriptions using KQL?' would make Azure Resource Graph the correct answer.
Why candidates choose this
Candidates may confuse Azure Resource Graph's ability to discover resources with the advisory and recommendation capabilities of Azure Advisor, especially since both involve resource analysis.
