Full question →easymultiple choiceObjective-mapped
A stateless web service must handle traffic spikes by adding or removing instances automatically based on CPU usage. Which Azure service fits best?
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
One larger standalone VM
A larger VM increases capacity, but it does not scale out automatically with demand.
B
Distractor review
Availability set with two VMs
An availability set improves availability, but it does not automatically add or remove instances.
C
Best answer
Virtual machine scale set with autoscale
A VM scale set with autoscale is designed for stateless workloads that need automatic instance scaling based on metrics.
D
Distractor review
Recovery Services vault backup
Backup supports recovery, but it does not provide real-time scaling for active traffic.
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: Virtual machine scale set with autoscale — A virtual machine scale set with autoscale is the best fit for a stateless service that needs to grow and shrink automatically. It lets Azure add or remove VM instances based on a metric such as CPU utilization, which helps match capacity to demand without manual intervention. This makes it a strong choice for web front ends and other horizontally scalable workloads. Why others are wrong: A larger standalone VM only increases fixed capacity. An availability set helps with resilience, but it does not perform automatic scaling. Recovery Services vault backup is for restore and protection, not for handling live traffic spikes or instance count changes.
