Quick Answer
The answer is an activity log alert. This is the correct choice because an activity log alert monitors subscription-level events recorded in the Azure Activity Log, and the deletion of a resource group is a specific control plane operation—'Microsoft.Resources/subscriptions/resourceGroups/delete'—that gets logged automatically. Unlike metric alerts or log query alerts, activity log alerts are designed precisely for these administrative actions, making them the ideal tool to trigger notifications when a resource group is removed. On the AZ-104 exam, this question tests your ability to distinguish between alert types: metric alerts monitor performance data, log alerts analyze workspace logs, and activity log alerts track Azure resource management events. A common trap is confusing activity log alerts with service health alerts, but remember that resource group deletion is a resource management event, not a service issue. To lock it in, use the memory tip: "Activity alerts for actions, metric alerts for performance."
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. 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 notify the security team whenever anyone deletes a resource group in the subscription. Which alert type should you configure?
A metric alert on CPU percentage
Why wrong: CPU metrics are unrelated to resource-group deletion events.
A budget alert
Why wrong: Budget alerts monitor spending thresholds, not admin operations.
An activity log alert
This targets Azure control-plane events such as deletions.
A log alert based only on guest OS event logs
Why wrong: Guest OS logs do not capture Azure subscription-level delete operations reliably.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
An activity log alert
Option C is correct because an activity log alert monitors subscription-level events recorded in the Azure Activity Log, including resource group deletion operations. When a user deletes a resource group, the 'Microsoft.Resources/subscriptions/resourceGroups/delete' operation is logged, and an activity log alert can be configured to trigger on that specific operation, sending notifications to the security team.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
A metric alert on CPU percentage
Why it's wrong here
CPU metrics are unrelated to resource-group deletion events.
A budget alert
Why it's wrong here
Budget alerts monitor spending thresholds, not admin operations.
An activity log alert
Why this is correct
This targets Azure control-plane events such as deletions.

A log alert based only on guest OS event logs
Why it's wrong here
Guest OS logs do not capture Azure subscription-level delete operations reliably.
Common exam traps
The trap here is that candidates often confuse activity log alerts with log alerts based on guest OS logs, not realizing that resource group deletions are control plane events captured in the Activity Log, not in guest OS event logs.
Detailed technical explanation
Activity log alerts are part of Azure Monitor and operate at the subscription scope, using Azure Resource Manager telemetry. They evaluate the 'status' field (e.g., 'Succeeded', 'Failed') of operations and support advanced conditions like 'Level' (Informational, Warning, Error) and 'Resource Provider'. In a real-world scenario, you could combine this with an Action Group that sends an email or SMS to the security team, or triggers a webhook to a SIEM system for incident response.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
