You have a virtual machine scale set that must increase the number of instances automatically when average CPU utilization exceeds 75 percent and decrease when utilization drops below 30 percent. What should you configure?

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

An Azure Monitor autoscale rule on the scale set

Autoscale rules support scaling out and in based on CPU thresholds.

B

Distractor review

A boot diagnostics configuration

Boot diagnostics captures startup logs and screenshots, not scaling logic.

C

Distractor review

An availability set

Availability sets improve resilience but do not provide autoscaling.

D

Distractor review

A custom script extension

A script extension can run scripts on VMs, but it is not the native scaling mechanism.

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: An Azure Monitor autoscale rule on the scale set — Autoscale settings on a Virtual Machine Scale Set allow instance counts to change automatically based on metric thresholds. Availability sets, boot diagnostics, and custom script extensions do not provide dynamic scaling behavior.
