Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
An application on an Azure VM has outgrown its current CPU and memory. The administrator wants to increase compute capacity without rebuilding the application or changing the VM image. 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 virtual machine to a larger size
Resizing the VM changes the amount of CPU, memory, and sometimes other capabilities assigned to the existing machine. This is the correct operational fix when the application needs more compute resources but does not need a new image or rebuild. It keeps the same VM and operating system while giving it more capacity. For an easy Azure administration scenario, this is the direct answer to a performance-capacity problem.
B
Distractor review
Create a new snapshot of the OS disk
A snapshot is for recovery or cloning, but it does not add more compute resources to the running VM.
C
Distractor review
Move the VM to an availability set
An availability set improves resilience, but it does not increase the VM's CPU or memory.
D
Distractor review
Attach a data disk
Adding a data disk increases storage capacity, not CPU or RAM for the 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.
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 virtual machine to a larger size — Resizing the VM is the correct choice when the application needs more CPU or memory. Azure lets you change the VM size to a SKU with larger compute resources without redeploying the application from scratch. This is a common administrative action and is different from adding storage or changing fault-tolerance settings. The question asks specifically for increased compute capacity, so resizing is the best fit. Why others are wrong: A snapshot protects disk data but does not change compute performance. An availability set helps with maintenance and host failure isolation, not with CPU or memory shortages. Attaching a data disk provides more storage space, but it does not make the VM itself more powerful. Only resizing directly addresses the compute bottleneck described in the scenario.
