Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
Exhibit
Requirement note: - ProductionApp must stay online during a single datacenter outage. - Region: East US 2 - The region supports multiple availability zones. - Two Windows VMs will host the app tier.
Based on the exhibit, which deployment choice should the administrator use to keep the application available if one datacenter in the Azure region fails?
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
Place both VMs in the same availability set.
An availability set protects against host maintenance and hardware failure, but not a full datacenter outage.
B
Best answer
Deploy the VMs across separate availability zones.
Availability zones place resources in physically separate datacenters within the region. If one datacenter fails, the other zone can continue serving traffic. This matches the requirement for surviving a single datacenter outage and is the preferred Azure design when zone support is available.
C
Distractor review
Use a proximity placement group for both VMs.
A proximity placement group improves latency by placing resources close together. It does not provide resilience against a datacenter failure.
D
Distractor review
Use a larger VM size for each virtual machine.
A larger VM size can improve performance, but it does not change the failure domain or add resilience.
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: Deploy the VMs across separate availability zones. — Availability zones are designed for resilience against datacenter-level failures inside a supported Azure region. By distributing the application VMs across different zones, the workload can keep running if one datacenter becomes unavailable. An availability set would only protect against host or rack issues within a datacenter, while proximity placement groups and larger VM sizes do not provide fault isolation. The exhibit specifically calls out a zone-capable region and a single datacenter outage, so zones are the right choice. Why others are wrong: An availability set is useful for planned maintenance and host failures, but it still keeps workloads within the same datacenter scope. A proximity placement group optimizes latency, not availability. Increasing VM size may improve capacity, but it does nothing to prevent service loss when a datacenter fails.
