Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A business stores audit logs in Azure Blob Storage. The account must remain available if an entire availability zone in the primary region fails, and analysts must still be able to read the data from the paired region if the primary region becomes unavailable. Which replication option should the administrator select?
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
Zone-redundant storage (ZRS)
ZRS protects against a zone failure within one region, but it does not provide a readable secondary regional copy.
B
Distractor review
Geo-redundant storage (GRS)
GRS adds a secondary regional copy, but it does not provide zone redundancy in the primary region or read access to the secondary.
C
Best answer
Read-access geo-zone-redundant storage (RA-GZRS)
RA-GZRS is the only option here that combines zone redundancy in the primary region with geo-replication to a paired region and read access to the secondary copy. That satisfies both requirements: survive a single-zone outage and still allow analysts to read from the secondary region if the primary region is unavailable.
D
Distractor review
Read-access geo-redundant storage (RA-GRS)
RA-GRS provides a readable secondary region, but the primary copy is not zone-redundant, so it does not meet 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: Read-access geo-zone-redundant storage (RA-GZRS) — RA-GZRS is the best fit because it protects data across zones in the primary region and also replicates it to a paired secondary region that can be read. The scenario requires both capabilities at the same time. ZRS alone stops at zone protection, while GRS and RA-GRS do not add primary-region zone redundancy. RA-GZRS is the only replication option that satisfies both resilience goals without changing the access model for the application or analysts. Why others are wrong: ZRS only covers a zone failure and has no secondary regional replica for read access. GRS and RA-GRS both replicate to a secondary region, but the primary copy is not zone-redundant, so they miss the first requirement. RA-GRS is closer, but it still lacks zone-level resilience in the primary region. The question requires both zone resilience and readable geo-replication.
