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 wants to monitor the performance of their Azure VMs and receive alerts when CPU usage exceeds 90%. Which Azure service should they use?
Azure Monitor
Azure Monitor provides metrics, logs, and alerting for Azure resources.
Azure Policy
Why wrong: Azure Policy enforces compliance rules; it does not monitor performance.
Azure Security Center
Why wrong: Azure Security Center provides security recommendations and threat detection, not performance monitoring.
Azure Cost Management
Why wrong: Cost Management tracks spending and budgets, not performance metrics.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Monitor
Azure Monitor is the correct service because it provides a comprehensive solution for collecting, analyzing, and acting on telemetry from Azure resources, including VMs. It includes metrics like CPU percentage and allows you to configure metric alerts that trigger when a threshold (e.g., 90% CPU usage) is exceeded. This directly meets the requirement for performance monitoring and alerting.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Azure Policy
Why it's wrong here
Azure Policy enforces compliance rules; it does not monitor performance.
Azure Security Center
Why it's wrong here
Azure Security Center provides security recommendations and threat detection, not performance monitoring.
Azure Cost Management
Why it's wrong here
Cost Management tracks spending and budgets, not performance metrics.
Common exam traps
The trap here is that candidates often confuse Azure Monitor with Azure Security Center, thinking both handle alerts, but Security Center is strictly for security-related alerts (e.g., vulnerabilities, threats) and not for performance metrics like CPU usage.
Detailed technical explanation
Azure Monitor collects platform metrics from Azure VMs at a default frequency of every 60 seconds for standard metrics like CPU percentage. When configuring a metric alert, you can set an aggregation window (e.g., 5 minutes) and a threshold (e.g., 90%), and the alert fires when the condition is met. Under the hood, Azure Monitor uses the Azure Metrics REST API and the Azure Resource Health pipeline to evaluate alert rules, and it supports action groups for notifications via email, SMS, webhooks, or integration with ITSM tools.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
