Exhibit
VM summary: Name: vm-web-01 Current size: Standard_D2s_v5 Average CPU over 24 hours: 91% Average memory pressure: 87% Business requirement: increase compute capacity while keeping the OS disk, installed applications, and data intact
Based on the exhibit, what should the administrator do to meet the performance requirement without rebuilding the server?
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
Distractor review
Attach an additional data disk and move the application binaries to it.
Adding a data disk may increase storage capacity, but it does not increase CPU or memory resources.
B
Best answer
Resize the VM to a larger SKU that provides more vCPU and RAM.
Resizing a VM is the standard way to increase compute capacity while preserving the existing OS disk and installed applications. The exhibit shows sustained high CPU and memory pressure, so moving to a larger size such as a higher D-series SKU addresses the bottleneck directly. This avoids rebuilding the server and keeps the workload on the same VM configuration with more resources.
C
Distractor review
Redeploy the VM from a different marketplace image.
Redeploying from another image would be disruptive and is unnecessary when the goal is only more compute capacity.
D
Distractor review
Place the VM in an availability set to spread processing across hosts.
An availability set improves resilience, but it does not increase the compute size of a single VM.
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.

Question 1
A route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?
Question 2
You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?
Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.

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: Resize the VM to a larger SKU that provides more vCPU and RAM. — The exhibit shows sustained CPU and memory pressure on the current VM size, so the correct remediation is to resize the VM to a larger SKU. Azure resizing increases available compute resources while preserving the OS disk and installed software. This is the least disruptive option when the application does not need a new image or a new deployment model. It is a common administrator action for performance remediation when scaling out is not required. Why others are wrong: A data disk adds storage, not CPU or memory. Redeploying from a marketplace image is unnecessary and can introduce configuration drift. An availability set changes placement for resilience, but it does not change the VM's compute capacity.
