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.
An operations team wants an email notification when the average CPU percentage on a VM stays above 85 percent for 10 minutes. Which two Azure Monitor components should they configure? Select two.
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 rule
A metric alert rule is correct because it monitors a specific VM performance metric (e.g., Percentage CPU) and triggers when the average value exceeds 85% for a duration of 10 minutes, as defined by the aggregation granularity and evaluation frequency. This rule evaluates the metric data at regular intervals and fires an alert when the condition is met, enabling automated notification.
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
Why this is correct
A metric alert evaluates VM performance data and can trigger when a threshold is crossed.

✓
An action group
Why this is correct
An action group defines who gets notified and which response actions run after the alert fires.

✗
Azure Bastion
Why it's wrong here
Azure Bastion is used for secure VM access, not for monitoring or alert delivery.
✗
A Recovery Services vault
Why it's wrong here
A Recovery Services vault protects backups and restores, not metric-based alert notifications.
✗
A resource lock
Why it's wrong here
A resource lock prevents changes or deletion, but it does not generate monitoring alerts.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the metric alert rule (which monitors performance metrics) with activity log alerts (which monitor resource configuration changes), or they mistakenly think Azure Bastion or Recovery Services vaults have monitoring capabilities, when in fact only the combination of a metric alert rule and an action group enables email notifications for metric thresholds.
Detailed technical explanation
How to think about this question
Under the hood, a metric alert rule uses Azure Monitor's metric time series database, which stores VM performance counters collected by the Azure Diagnostics extension or the Azure Monitor Agent. The alert rule evaluates the 'Average' aggregation of the 'Percentage CPU' metric over a sliding window of 10 minutes (e.g., using a 10-minute period with a frequency of 1 minute), and when the threshold is breached, it fires an alert that invokes the linked action group. In real-world scenarios, you might configure multiple conditions in a single alert rule (e.g., CPU > 85% for 10 minutes AND memory < 10%) to reduce noise, but the action group remains the central mechanism for sending email, SMS, or webhook notifications.
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.
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
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.
