Azure Monitor is the correct choice because it delivers a unified platform for collecting, analyzing, and acting on telemetry from Azure VMs, including both custom metrics and logs. By deploying the Azure Monitor Agent, you can capture performance counters and event logs directly from the guest OS, then configure metric alerts or log alerts that trigger on specific thresholds, meeting every stated requirement for monitoring performance and health. On the AZ-305 exam, this question tests your ability to distinguish Azure Monitor from services like Azure Service Health or Azure Advisor—a common trap is confusing Azure Monitor’s operational data collection with Service Health’s platform-level notifications. Remember that Azure Monitor is the single pane of glass for all VM telemetry, while other services address separate concerns like cost or reliability. A useful memory tip: think of “Monitor” as the “M” in “Metrics and Logs”—if you need both custom metrics and log-based alerts, Azure Monitor is your answer.
AZ-305 Practice Question: Design identity, governance, and monitoring solutions
This AZ-305 practice question tests your understanding of design identity, governance, and monitoring solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
You need to monitor the performance and health of your Azure virtual machines, including custom metrics and logs. You also need to set up alerts based on specific thresholds. Which Azure service should you use?
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 choice because it provides a comprehensive solution for collecting, analyzing, and acting on telemetry from Azure virtual machines, including custom metrics and logs. It integrates with the Azure Monitor Agent to gather performance counters and event logs, and supports metric alerts and log alerts based on specific thresholds, directly meeting all stated requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Application Insights
Why it's wrong here
Application Insights is for application performance monitoring, not infrastructure.
✗
Azure Service Health
Why it's wrong here
Service Health provides information about Azure service issues, not VM performance.
✗
Log Analytics
Why it's wrong here
Log Analytics is a tool within Azure Monitor for querying logs, but Azure Monitor is the overarching service.
✓
Azure Monitor
Why this is correct
Azure Monitor provides full monitoring, including metrics, logs, and alerts for VMs.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Log Analytics (a data store and query tool) with Azure Monitor (the full monitoring and alerting platform), leading them to select Option C when Azure Monitor is the correct overarching service that includes Log Analytics and alerting capabilities.
Detailed technical explanation
How to think about this question
Azure Monitor uses the Azure Monitor Agent (AMA) to collect performance counters (e.g., CPU, memory) and Windows/Linux event logs from VMs, storing them in Log Analytics workspaces for querying with Kusto Query Language (KQL). Metric alerts evaluate at a frequency as low as 1 minute, while log alerts can trigger based on complex queries over historical data, enabling scenarios like alerting when disk queue length exceeds a threshold for 5 consecutive minutes.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
