The operations team wants 3 to 8 identical Linux VM instances, with more instances added when average CPU stays above 70 percent for 10 minutes and removed when load falls. Which three settings should be configured? Select three.
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
Use a virtual machine scale set for the identical application instances.
A VM scale set is the compute service built for multiple identical instances with centralized scaling and management. It is the correct foundation for a workload that expands and contracts over time.
B
Best answer
Create an autoscale profile with a scale-out rule based on average CPU utilization.
The autoscale profile is where the CPU threshold and evaluation window are defined. A scale-out rule tied to average CPU above 70 percent for 10 minutes matches the business requirement precisely.
C
Best answer
Set minimum and maximum instance counts so the service cannot scale below 3 or above 8.
Minimum and maximum bounds keep autoscale within the required operating range. They prevent over-scaling costs and ensure the service always keeps at least the minimum capacity online.
D
Distractor review
Place the VMs in an availability set instead of using a scale set.
An availability set improves resilience, but it does not provide built-in horizontal autoscaling. It would not meet the requirement to add and remove instances automatically based on CPU usage.
E
Distractor review
Clone the VM manually whenever CPU rises and remove clones by hand later.
Manual cloning is slow, error-prone, and defeats the goal of automatic scaling. It also makes it harder to maintain identical configuration across instances over time.
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: Use a virtual machine scale set for the identical application instances. — To satisfy the scaling requirement, the administrator should use a VM scale set, define an autoscale profile, and set minimum and maximum limits. The scale set provides the identical instance model, the autoscale profile translates CPU pressure into scaling actions, and the bounds keep the workload inside the required 3-to-8 range. This is the standard Azure approach for elastic compute. Why others are wrong: An availability set improves resilience but does not scale instances automatically. Manual cloning cannot react quickly or consistently to CPU thresholds. The requirement is specifically about elastic, policy-driven instance changes, which is what VM scale sets and autoscale are designed to deliver.
