The answer is a metric alert and an action group. A metric alert continuously evaluates a specific resource metric, such as CPU utilization, and fires when the value exceeds a defined threshold—like 90%—for a specified duration of 15 minutes. The action group then handles the notification, in this case sending an email, by linking the alert to the desired response. On the AZ-104 exam, this pairing tests your understanding of how Azure Monitor separates monitoring logic from notification delivery; a common trap is confusing metric alerts with activity log alerts, which track operational events rather than resource performance. Remember that the metric alert watches the resource, while the action group decides who gets the message. A simple memory tip: “Metric measures, action acts”—the alert detects the condition, and the action group delivers the response.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A metric alert and an action group
A metric alert monitors a specific resource metric (like CPU utilization) and triggers when a condition (e.g., >90%) is met for a given duration (15 minutes). An action group defines the notification or remediation action (e.g., sending an email). Together, they fulfill the requirement to send an email when CPU utilization exceeds 90% for 15 minutes.
Key principle: Metric alerts monitor numerical data from Azure resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
A metric alert and an action group
Why this is correct
A metric alert detects the threshold breach and the action group sends the email notification.
Related concept
Metric alerts monitor numerical data from Azure resources.
✗
An activity log alert only
Why it's wrong here
Activity log alerts do not evaluate CPU performance metrics.
✗
A resource lock and Azure Advisor
Why it's wrong here
Neither component is used to send threshold-based operational notifications.
✗
A budget alert and a private endpoint
Why it's wrong here
Budget alerts monitor cost, and private endpoints provide connectivity.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing activity log alerts (which monitor control-plane events) with metric alerts (which monitor performance data), leading candidates to incorrectly select an activity log alert for CPU utilization monitoring.
Detailed technical explanation
How to think about this question
Metric alerts in Azure Monitor use a time-series signal from the resource's metrics (e.g., Percentage CPU) and evaluate it against a threshold using a statistical function (e.g., average, max) over a specified aggregation window (e.g., 15 minutes). The action group can include email, SMS, webhook, ITSM, or Azure Functions, and supports multiple notification channels. Under the hood, the alert rule is evaluated every minute (frequency) based on the metric data stored in Azure Monitor Metrics, ensuring near-real-time detection.
KKey Concepts to Remember
Metric alerts monitor numerical data from Azure resources.
Action groups define notification preferences and actions for alerts.
CPU utilization is a standard metric available for Azure VMs.
Alerts can be configured with specific thresholds and time aggregations.
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
Metric alerts monitor numerical data from Azure resources.
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.

What is the correct answer to this question?
The correct answer is: A metric alert and an action group — A metric alert monitors a specific resource metric (like CPU utilization) and triggers when a condition (e.g., >90%) is met for a given duration (15 minutes). An action group defines the notification or remediation action (e.g., sending an email). Together, they fulfill the requirement to send an email when CPU utilization exceeds 90% for 15 minutes.

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. The operations team wants an email and SMS notification whenever any production virtual machine's average CPU stays above 85 percent for 10 minutes. They also want to reuse the same notification targets for future alerts. What should they configure?
medium
A.A diagnostic setting on each VM that sends metrics to a storage account
✓ B.An action group attached to a metric alert rule
C.A Log Analytics query alert with no notification target
D.A resource lock on the virtual machines
Why B: Option B is correct because an action group in Azure Monitor defines the notification targets (email, SMS, etc.) for alerts, and a metric alert rule can be configured to trigger when the average CPU percentage exceeds 85% for 10 minutes. By attaching the same action group to multiple alert rules, the operations team can reuse the notification targets for future alerts without reconfiguring them each time.
Variation 2. A production virtual machine is experiencing intermittent performance spikes. The operations team wants an alert when average CPU usage stays above 80 percent for 10 minutes and wants email and SMS notifications sent automatically. What should the administrator configure in Azure Monitor?
medium
A.Create a log search alert on the VM performance data and attach a resource lock.
✓ B.Create a metric alert on Percentage CPU and associate an action group with email and SMS receivers.
C.Assign an Azure Policy definition to the VM to stop it when CPU exceeds the threshold.
D.Enable diagnostic settings on the VM and send the data only to a storage account.
Why B: Option B is correct because Azure Monitor metric alerts can evaluate real-time performance counters like Percentage CPU against a threshold (e.g., 80%) over a specified duration (e.g., 10 minutes). By associating an action group with email and SMS receivers, the alert automatically triggers the desired notifications without requiring log ingestion or complex queries.
Variation 3. A production virtual machine must trigger an immediate notification whenever average CPU stays above 85 percent for 15 minutes, and the same event must also start an Azure Function that opens an incident ticket. Which two Azure Monitor components should you configure? Select two.
medium
✓ A.Create a metric alert rule on the VM CPU percentage.
✓ B.Add an action group that sends email and invokes the Azure Function.
C.Enable a diagnostic setting on the VM without creating an alert rule.
D.Create a Log Analytics workspace and rely on manual queries only.
E.Apply a resource lock so CPU usage changes are blocked.
Why A: A metric alert rule on the VM CPU percentage is correct because it monitors the specific metric (Percentage CPU) and triggers when the average exceeds 85% for 15 minutes, meeting the notification requirement. This rule evaluates the metric at regular intervals and fires when the condition is met, which is the standard Azure Monitor approach for real-time metric-based alerts.
