Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
An application on an Azure VM needs more CPU and memory. The administrator wants to keep the same OS disk and installed apps, without redeploying the server. What should be done?
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
Resize the VM to a larger size
Resizing the VM changes the allocated compute resources while keeping the same operating system disk and data disks. This is the usual way to give an existing VM more CPU and memory without rebuilding the server. In many cases, you only need to stop the VM briefly, choose a larger size, and start it again.
B
Distractor review
Reimage the VM
Reimaging replaces the OS disk contents, which would remove the current installed applications and settings.
C
Distractor review
Move the VM into a different availability zone
Changing zones is about resilience placement, not increasing CPU or memory capacity.
D
Distractor review
Create a new storage account
A storage account is unrelated to adding compute capacity to the virtual machine itself.
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.
Question 4
You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?
Question 5
You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?
Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
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 size — Resizing the VM is the correct action when the server needs more CPU and memory but should keep the same operating system and applications. Azure VM sizes define the amount of compute resource assigned to the machine. A resize lets you move to a bigger SKU without rebuilding the workload, which makes it the most straightforward operational change for capacity growth. Why others are wrong: Reimaging would overwrite the OS disk and is not appropriate when you want to preserve the current application setup. Moving to another availability zone does not add CPU or memory, so it does not solve the performance problem. Creating a new storage account is unrelated to VM compute sizing and would not change the server's capacity.
