Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
Exhibit
Monitoring requirement - 5 Linux VMs in one resource group - Collect CPU percentage and logical disk free space - Keep ingestion cost as low as possible - No application tracing is required - Current state: No guest monitoring agent configured
Based on the exhibit, what should the administrator deploy to monitor CPU and free disk space on a small set of VMs while keeping telemetry cost low?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Deploy Azure Monitor Agent and collect only the required performance counters with a data collection rule.
Azure Monitor Agent with a targeted data collection rule is the cost-aware choice because it collects only the specific performance data needed. The administrator can scope the rule to the five VMs and include just CPU and disk free space counters, avoiding broad log ingestion. This meets the monitoring requirement without paying to send unnecessary telemetry to Log Analytics.
B
Distractor review
Enable diagnostic settings on each VM and send all guest logs to a storage account.
This can create more data than needed and does not provide the cleanest per-counter collection approach for VM performance monitoring.
C
Distractor review
Install Application Insights on each VM and enable request tracing.
Application Insights is intended for application telemetry, not basic host performance counters on virtual machines.
D
Distractor review
Create a resource lock on each VM to preserve the current state.
A lock prevents changes, but it does not collect or analyze performance telemetry.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Deploy Azure Monitor Agent and collect only the required performance counters with a data collection rule. — For lightweight VM monitoring, Azure Monitor Agent plus a data collection rule is the best fit. It lets the administrator choose exactly which counters to gather, such as CPU and free disk space, and apply the rule only to the required machines. That approach gives useful operational visibility while avoiding unnecessary ingestion charges from broad diagnostic collection or application-centric tooling that does not fit the requirement. Why others are wrong: Sending all guest logs to storage is broader than needed and is not the preferred cost-aware performance monitoring design. Application Insights tracks application behavior, not host counters. A resource lock has no monitoring function at all. The correct solution is targeted telemetry collection, not generic log capture or change prevention.
