- A
Configure Azure Monitor VM insights with availability metric alerts set to fire when the VM is unavailable for 2 out of the last 5 minutes.
VM insights availability metrics provide accurate unavailability detection with dynamic thresholds, reducing false positives.
- B
Create an Azure Service Health alert for the 'Virtual machine' service.
Why wrong: Service Health alerts are for Azure service incidents, not individual VM health.
- C
Create an Azure Monitor alert based on the Activity Log for 'Virtual Machine Guest OS Unresponsive' events.
Why wrong: Activity Log alerts do not capture VM-level unavailability; they capture management events.
- D
Deploy the Log Analytics agent on each VM and create an alert for when heartbeat data is missing for 5 minutes.
Why wrong: Heartbeat alerts can have false positives if the agent is delayed, and single-metric alerts may cause alert fatigue.
Quick Answer
The correct design is to configure Azure Monitor VM insights with availability metric alerts set to fire when the VM is unavailable for 2 out of the last 5 minutes. This approach directly meets the 99.99% SLA monitoring requirement by using the platform’s native availability metric, which measures actual VM responsiveness with high precision, and the multi-measurement window (2 of 5 minutes) filters out transient blips, minimizing false positives and preventing alert fatigue. On the AZ-305 exam, this scenario tests your understanding of Azure Monitor’s metric alerts versus Activity Log or Service Health alerts—common traps include choosing heartbeat-based Log Analytics alerts, which introduce delay and noise, or single-metric alerts that fire on every hiccup. Remember the memory tip: “Two of five keeps the SLA alive”—meaning a 2-out-of-5-minute evaluation window is the sweet spot for reliable, low-noise VM unavailability detection.
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. 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.
Your organization is deploying a critical application in Azure that must maintain an uptime SLA of 99.99%. The application runs on Azure Virtual Machines in a single region. You need to design a monitoring solution that alerts the operations team within 5 minutes of any VM unavailability. The solution must minimize false positives and avoid alert fatigue. What should you include in the design?

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
Configure Azure Monitor VM insights with availability metric alerts set to fire when the VM is unavailable for 2 out of the last 5 minutes.
Option D is correct because availability metrics from Azure Monitor provide accurate unavailability detection with minimal false positives, and multi-metric alerts reduce noise. Option A is wrong because Activity Log alerts only fire on configuration changes, not on VM unavailability itself. Option B is wrong because Service Health alerts cover Azure service incidents but not VM-level failures. Option C is wrong because Log Analytics agent-based heartbeat alerts can have delays and require additional configuration, and single-metric alerts may cause alert fatigue.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are designing a monitoring solution for a critical application running on Azure virtual machines. The application must maintain an SLA of 99.99% uptime. You need to be notified within five minutes if any VM becomes unavailable. What should you configure?
medium- A.Log Analytics workspaces
- B.Azure Advisor recommendations
- C.Azure Service Health alerts
- ✓ D.Azure Monitor VM Insights with availability metric alerts
Why D: Option D is correct because VM Insights with availability metric alerts monitors the heartbeat of Azure VMs and triggers an alert within five minutes if a VM becomes unavailable. This directly supports the 99.99% SLA requirement by enabling rapid notification of downtime, using the 'VM Availability Metric (Preview)' which tracks the VM's running state via the Azure Resource Health provider.
