Exhibit
Environment notes: - Region: East US 2 - Workload: two identical web VMs behind a load balancer - Requirement: the application must keep running if one datacenter in the region becomes unavailable - Current plan: both VMs would be placed in the same availability set
Based on the exhibit, which deployment change best meets the resilience requirement for the application VMs?
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
Keep both VMs in the same availability set to spread them across update domains only.
An availability set helps with maintenance and host failures, but it does not protect against a full datacenter outage.
B
Best answer
Place each VM in a different availability zone and keep the load balancer in front.
Availability zones provide isolation across datacenters within the same region. By placing the two VMs in different zones, the workload can continue if one zone or datacenter becomes unavailable. The load balancer can direct traffic to the surviving VM. This design matches the stated requirement more closely than an availability set, which only spreads VMs across fault and update domains inside a single datacenter cluster.
C
Distractor review
Deploy both VMs into a proximity placement group to reduce latency between them.
A proximity placement group is for low-latency placement, not for fault isolation across datacenters.
D
Distractor review
Move the VMs into a single availability set and add more managed disks for redundancy.
Managed disks improve storage durability, but they do not provide compute resilience against datacenter failure.
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: Place each VM in a different availability zone and keep the load balancer in front. — Availability zones are the correct choice when the business requires protection from a datacenter failure in a region that supports zones. Placing the VMs in different zones provides physical separation at the datacenter level, which is stronger than an availability set. An availability set helps with planned maintenance and some host failures, but it does not span datacenters. The load balancer can keep the service available by routing traffic to the remaining healthy VM. Why others are wrong: An availability set does not provide zone-level fault isolation. A proximity placement group improves performance, not resilience. Managed disk redundancy helps storage availability, but the service would still fail if both VMs were in the same fault domain during a datacenter outage.
