Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
Two app VMs must stay available during planned host maintenance in the same region. Datacenter-level redundancy is not required, but the VMs should be spread across update domains. What should you 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
Best answer
Availability set
An availability set spreads VMs across fault and update domains to reduce the impact of host maintenance and hardware failure.
B
Distractor review
Availability zone
Zones provide stronger datacenter-level separation, which is more than the scenario requires.
C
Distractor review
Azure Backup
Backup helps recovery after data loss, but it does not keep VMs running during maintenance.
D
Distractor review
Managed disk
Managed disks store VM data, but they do not control placement across maintenance boundaries.
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 set — An availability set is the correct choice when you want VMs distributed across update domains and fault domains within the same datacenter location. That setup helps reduce downtime during planned maintenance and some host failures. Because the requirement does not call for protection from a full datacenter outage, an availability set provides the right level of resilience without the added complexity of zones. Why others are wrong: Availability zones are better for datacenter-level failure protection, which is more than needed here. Azure Backup is for restoring data or VMs after a problem, not for maintaining live availability. Managed disks are required for storage, but they do not influence fault-domain or update-domain placement.
