AZ-900 Describe Azure management and governance Practice Question
Which Azure feature provides continuous application performance monitoring with automatic anomaly detection?
⚠ Common exam trap
A common mix-up: candidates confuse Azure Monitor (the umbrella service) with Application Insights (the specific APM component), leading them to choose Azure Monitor because it sounds like the most general monitoring tool, but the question explicitly asks for 'continuous application performance monitoring with automatic anomaly detection,' which is a core feature of Application Insights, not Azure Monitor alone.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Application Insights
Azure Application Insights is the correct answer because it is an extensible Application Performance Management (APM) service specifically designed for continuous monitoring of live applications. It automatically detects performance anomalies through features like Smart Detection, which uses machine learning algorithms to analyze telemetry data (e.g., request rates, response times, failure rates) and proactively identify unusual patterns without manual threshold configuration.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure Monitor
Why it's wrong here
Azure Monitor is the umbrella platform that collects, analyzes, and acts on telemetry from Azure resources, infrastructure, and applications. While Application Insights is a feature of Azure Monitor, Azure Monitor itself is not the specific APM tool for web apps; it lacks the out-of-the-box client-side user behavior tracking, session/request correlation, and application-specific performance diagnostic views that Application Insights provides.
- ✗
Azure Log Analytics
Why it's wrong here
Azure Log Analytics is the querying and analytics engine used to run KQL (Kusto Query Language) queries against log data collected by Azure Monitor. It stores and correlates log data but does not independently offer live application performance monitoring, automatic anomaly detection, or user behavior analytics for web apps; those capabilities belong to Application Insights, which can send its data to Log Analytics for deeper querying.
- ✓
Azure Application Insights
Why this is correct
Azure Application Insights is the application performance management (APM) service within Azure Monitor, purpose-built for live web applications. It automatically collects request rates, response times, failure counts, dependency calls, page views, and custom events, and uses built-in anomaly detection to alert on deviations. This directly matches the question's requirement to monitor a live web app's performance and user behavior with automatic anomaly detection.
- ✗
Azure Network Watcher
Why it's wrong here
Azure Network Watcher is a regional network monitoring and diagnostics service focused on infrastructure-level connectivity, such as packet capture, connection troubleshoot, and NSG flow logs. It does not provide application-level telemetry like request rates, dependency tracking, or user session analysis, so it cannot fulfill the requirement to monitor live web app performance and user behavior.
