Exhibit
Business requirement: - Application must survive a datacenter-level outage - Azure region supports availability zones - The workload can run from multiple instances - The team wants to place instances in separate fault domains if possible
Based on the exhibit, a workload must remain available even if one datacenter in an Azure region becomes unavailable. The region supports zone deployment. What should the administrator configure?
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
An availability set.
An availability set protects against host-level failures, but not a whole datacenter outage in the region.
B
Best answer
Availability zones.
Availability zones place resources in separate physically isolated datacenters within the same region. If one datacenter becomes unavailable, the workload can continue running in another zone. That is the correct resilience option when the requirement explicitly calls for protection from a datacenter-level outage.
C
Distractor review
A resource lock.
A resource lock prevents changes or deletion, but it does not provide any failover or high availability capability.
D
Distractor review
A user-defined route.
A user-defined route changes network path selection, but it does not protect compute resources from 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: Availability zones. — Availability zones are the best answer because they are specifically built to provide resilience against datacenter-level failures inside a region. By deploying resources across zones, the application can keep running even if one zone becomes unavailable. This provides a stronger fault-tolerance model than an availability set and matches the business requirement exactly. Why others are wrong: An availability set only protects against host maintenance and host failures within a datacenter, not a full datacenter outage. A resource lock is administrative protection, not availability protection. A user-defined route affects traffic routing, but it cannot keep compute instances online if a datacenter fails.
