A reporting server must be resized from 4 vCPU to 8 vCPU for a four-hour batch window. The VM name, NIC, private IP, and attached managed disks must stay the same, and the team accepts a brief outage during the change. Which two actions should you choose? Select two.
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
Deallocate the VM before changing its size.
Most VM size changes require the VM to be deallocated first. This step preserves the VM resource and attached managed disks while allowing Azure to move the compute allocation.
B
Best answer
Resize the VM to a larger supported size.
Resizing is the action that actually changes the compute capacity from 4 vCPU to 8 vCPU. Combined with deallocation, it meets the temporary performance requirement without rebuilding the VM.
C
Distractor review
Delete the VM and recreate it with a new size.
Deleting and recreating the VM is unnecessary and would introduce risk to the existing VM identity, NIC association, and operational continuity. The scenario explicitly wants to keep those items the same.
D
Distractor review
Generalize the VM first to preserve the existing configuration.
Generalizing is used for creating reusable images, not for resizing a live server. It would add complexity and is unrelated to the brief scaling window described.
E
Distractor review
Take a snapshot of the OS disk instead of resizing.
Snapshots are useful for point-in-time recovery, but they do not increase compute capacity. The problem is capacity, not backup, so a snapshot does not satisfy the business requirement.
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: Deallocate the VM before changing its size. — To change the compute size while keeping the same VM, NIC, private IP, and disks, you typically deallocate the VM and then resize it to a larger supported SKU. Deallocation allows Azure to free the current placement, and resizing applies the new compute resources. This approach gives the reporting server the temporary capacity it needs without recreating the machine or changing its identity. Why others are wrong: Deleting and recreating the VM is more disruptive than needed and can alter the machine’s identity and operational setup. Generalizing is for image creation, not resizing. A snapshot protects data but does not solve the performance requirement. The only options that directly address the temporary capacity change while preserving the existing VM are deallocation and resize.
