Full question →easymulti selectObjective-mapped
A team wants a storage option that stays available if one availability zone in the primary region fails. Which two redundancy options meet that requirement? Select two.
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
Zone-redundant storage (ZRS).
ZRS replicates data across multiple availability zones in the primary region, which helps the storage remain available if one zone fails.
B
Best answer
Geo-zone-redundant storage (GZRS).
GZRS combines zone redundancy in the primary region with geo-replication to a paired region, so it also meets the zone-failure requirement.
C
Distractor review
Locally redundant storage (LRS).
LRS keeps copies within a single datacenter scale unit, so it does not provide zone-level resilience for a zone outage.
D
Distractor review
Geo-redundant storage (GRS).
GRS adds geo-replication, but it does not provide zone redundancy in the primary region. A single zone failure can still affect the primary copy.
E
Distractor review
Read-access geo-redundant storage (RA-GRS).
RA-GRS provides a readable secondary region, but it does not add zone redundancy in the primary region. It is not the best fit for the zone-failure 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 and GZRS are the two redundancy choices that protect the primary region against a single availability zone failure. ZRS spreads copies across zones in one region, while GZRS adds geo-replication on top of zone redundancy. Both satisfy the need for higher availability during a zone outage, which is the key requirement in the scenario. Why others are wrong: LRS is limited to one datacenter boundary and does not cover a zone outage. GRS and RA-GRS add replication to another region, but they do not provide zone-level resilience in the primary region. The difference is subtle, but the question asks specifically about surviving one availability zone failure.
