The answer is an action group. This is the correct first configuration because in Azure Monitor, action groups serve as the reusable container for notification targets like email and SMS, allowing you to define them once and then reference them across multiple alert rules. By decoupling the notification method from the alert logic, Azure ensures that when you create a metric alert rule for the CPU threshold, you simply attach the pre-configured action group, meeting the requirement for reusability. On the AZ-104 exam, this concept tests your understanding of Azure Monitor’s architecture, where a common trap is to mistakenly configure the alert rule first or try to set notifications directly within the rule—both of which break reusability. Remember the memory tip: “Action groups are the reusable address book; alerts just send the mail.”
AZ-104 Monitor and Maintain Azure Resources Practice Question
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.
A company wants an alert to be sent by email and SMS whenever a production virtual machine's CPU percentage goes above 80 percent. The administrator also wants the notification targets to be reusable by other alerts later. What should the administrator configure first?

Correct answer & explanation
✓
An action group
An action group (B) is the correct first configuration because it defines the notification targets (email, SMS) that can be reused across multiple alert rules. In Azure Monitor, alert rules are decoupled from notification actions; you create an action group once and then reference it in any metric alert rule, including the CPU percentage threshold rule needed here. This ensures the administrator can meet the requirement for reusable notification targets.
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.
✗
A metric alert rule only
Why it's wrong here
A metric alert can detect the CPU condition, but it does not by itself define reusable notification recipients.
✓
An action group
Why this is correct
An action group stores the notification targets, such as email and SMS recipients, so multiple alerts can reuse the same response action.
Clue confirmation
The clue word "first" in the question point toward this answer.

✗
A service health alert
Why it's wrong here
Service health alerts report Azure platform issues, not a virtual machine's CPU usage.
✗
A diagnostic setting
Why it's wrong here
Diagnostic settings send logs and metrics to destinations, but they do not define alert recipients.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think a metric alert rule inherently includes notification settings, but Azure separates the condition (alert rule) from the notification method (action group) to enforce reusability and centralized management.
Detailed technical explanation
How to think about this question
Action groups in Azure Monitor support multiple notification channels (email, SMS, webhook, ITSM, etc.) and are defined at the subscription or resource group level. When an alert rule fires, it invokes the action group via an HTTP POST to the Azure Monitor backend, which then dispatches the notifications asynchronously. A common real-world scenario is creating a single 'Critical Ops Team' action group with email and SMS, then reusing it for CPU, memory, and disk alerts across all production VMs.

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.

Variation 1. A team needs an alert that emails the operations group whenever a VM's average CPU percentage stays above 85% for 10 minutes. Which two Azure Monitor components must you configure? Select two.
easy
✓ A.A metric alert rule on the VM CPU metric
✓ B.An action group with an email receiver
C.A Recovery Services vault
D.A private endpoint for the virtual machine
E.A blob lifecycle management policy
Why A: A metric alert rule on the VM CPU metric is required because it continuously monitors the 'Percentage CPU' metric and triggers when the average value exceeds 85% for a duration of 10 minutes. This rule evaluates the condition using the aggregation type 'Average' and the window size set to PT10M (ISO 8601 format). Without this rule, no alert condition exists to detect the threshold breach.
