Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A healthcare application stores files that must be protected against a single datacenter outage in the region. The team does not need a secondary region for read access, and they want the simplest resilient option. Which storage redundancy should they choose?
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
Locally redundant storage (LRS)
LRS is limited to one datacenter, so it does not address a datacenter outage requirement.
B
Best answer
Zone-redundant storage (ZRS)
ZRS stores copies across multiple zones in the region, which helps the data survive a datacenter or zone-level outage without needing another region.
C
Distractor review
Geo-zone-redundant storage (GZRS)
GZRS adds replication to another region, which is more than the scenario requires.
D
Distractor review
Read-access geo-redundant storage (RA-GRS)
RA-GRS provides secondary-region read access, but that is unnecessary for a single-region outage requirement.
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: Zone-redundant storage (ZRS) — ZRS is the simplest resilient option for protecting against a datacenter or zone outage within a region. It keeps copies in multiple availability zones, so the application can continue accessing data if one zone becomes unavailable. Because the team does not need another region or secondary read access, ZRS provides the right balance of availability and simplicity for the requirement. Why others are wrong: LRS keeps data inside one datacenter and cannot survive a datacenter loss. GZRS and RA-GRS replicate to a secondary region, which adds extra capability and complexity that the scenario does not need. The question asks for regional resilience only, so a zone-based option is more appropriate.
