Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A customer-facing application runs on two Azure VMs. The business wants the application to stay available even if one datacenter in the Azure region has an outage. Which availability option should the administrator use?
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
Availability set
Availability sets protect against host and maintenance events within a datacenter, but they do not span separate zones.
B
Best answer
Availability zones
Availability zones place resources in physically separate datacenters within the same Azure region. That gives the application protection against a full datacenter failure, which is the scenario described. When the workload must survive a zone outage, zones are the right resiliency choice rather than a same-datacenter availability set.
C
Distractor review
Proximity placement group
Proximity placement groups reduce latency between resources, but they do not provide datacenter-level resiliency.
D
Distractor review
Azure Load Balancer
A load balancer distributes traffic, but it does not itself provide protection from a datacenter outage.
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: Availability zones — Availability zones are the correct choice when the requirement is protection from a complete datacenter failure in a region. Zones are separate physical locations, so placing the VMs across zones increases resilience beyond what an availability set can provide. This is the right design for customer-facing workloads that must keep serving traffic during a zone outage. The administrator should choose the zonal deployment option that matches the region's capabilities. Why others are wrong: An availability set helps with host and update domain issues inside one datacenter, but it does not protect against a full zone outage. A proximity placement group is used to keep resources physically close for performance, not resilience. An Azure Load Balancer improves traffic distribution, but it is not a fault-isolation construct. Only availability zones directly address the datacenter-failure requirement.
