This AZ-104 practice question tests your understanding of monitor and maintain azure resources. 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. A key principle to apply: metric alerts monitor numerical data from Azure resources.. 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 receive an email when average CPU usage on VM-App01 exceeds 85 percent for 10 minutes. Which Azure Monitor components should you configure?
A metric alert and an action group
This combination detects the threshold breach and sends the notification.
A resource lock and Azure Advisor
Why wrong: Neither of these sends threshold-based email notifications.
An activity log alert only
Why wrong: Activity log alerts focus on management events, not VM CPU metrics.
A budget alert
Why wrong: Budget alerts monitor cost, not CPU utilization.
Answer choices
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 Azure resource metric (like CPU percentage) and triggers when a condition (e.g., average > 85%) is met over a specified evaluation period (e.g., 10 minutes). An action group defines the notification actions (e.g., sending an email) when the alert fires. Together, they fulfill the requirement to receive an email based on a performance threshold.
Key principle: Metric alerts monitor numerical data from Azure resources.
Answer analysis
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
This combination detects the threshold breach and sends the notification.
Related concept
Metric alerts monitor numerical data from Azure resources.
A resource lock and Azure Advisor
Why it's wrong here
Neither of these sends threshold-based email notifications.
An activity log alert only
Why it's wrong here
Activity log alerts focus on management events, not VM CPU metrics.
A budget alert
Why it's wrong here
Budget alerts monitor cost, not CPU utilization.
Common exam traps
The trap here is confusing metric alerts (for performance metrics) with activity log alerts (for management events) or budget alerts (for cost), leading candidates to pick an option that monitors the wrong type of data.
Detailed technical explanation
Metric alerts use Azure Monitor's multi-dimensional metric signals, evaluated by the alert engine at a frequency defined by the 'frequency' and 'window size' parameters. For a 10-minute evaluation, the alert uses a 'statistic' of 'average' over a 'window size' of PT10M (ISO 8601 duration). The action group can include email, SMS, webhook, ITSM, or Azure Automation runbooks, and supports 'action group rules' for dynamic suppression or routing.
Key takeaway
Metric alerts monitor numerical data from Azure resources.
Real-world example
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.
