- A
Locally redundant storage (LRS)
Why wrong: LRS keeps data within one datacenter and does not provide a readable secondary region.
- B
Zone-redundant storage (ZRS)
Why wrong: ZRS protects against zone failure inside a region, but it does not replicate to another region.
- C
Geo-redundant storage (GRS)
Why wrong: GRS replicates to a secondary region, but the secondary region is not readable during normal operations.
- D
Read-access geo-redundant storage (RA-GRS)
RA-GRS replicates data to a secondary region and allows reads from that secondary copy, which fits the requirement exactly.

AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A records team wants blobs to be replicated to a secondary region, and the secondary copy must be readable if the primary region becomes unavailable. Which redundancy option should you choose?

Correct answer & explanation
✓
Read-access geo-redundant storage (RA-GRS)
RA-GRS (Read-access geo-redundant storage) is correct because it provides geo-redundant replication (GRS) to a secondary region, plus read access to the secondary copy even if the primary region is unavailable. This ensures the blob data is replicated asynchronously to a paired secondary region, and the secondary endpoint can be read immediately during a primary outage, meeting the team's requirement for readable secondary copies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Locally redundant storage (LRS)
Why it's wrong here
LRS keeps data within one datacenter and does not provide a readable secondary region.
When this WOULD be correct
If the question specifies that cost is the primary concern and the data does not need to be available in case of a regional disaster, LRS would be the correct choice.
- ✗
Zone-redundant storage (ZRS)
Why it's wrong here
ZRS protects against zone failure inside a region, but it does not replicate to another region.
- ✗
Geo-redundant storage (GRS)
Why it's wrong here
GRS replicates to a secondary region, but the secondary region is not readable during normal operations.
- ✓
Read-access geo-redundant storage (RA-GRS)
Why this is correct
RA-GRS replicates data to a secondary region and allows reads from that secondary copy, which fits the requirement exactly.
Clue confirmation
The clue word "primary" in the question point toward this answer.

Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓Read-access geo-redundant storage (RA-GRS)Correct answer▾
Why this is correct
RA-GRS replicates data to a secondary region and allows reads from that secondary copy, which fits the requirement exactly.
✗Locally redundant storage (LRS)Wrong answer — click to see why▾
Why this is wrong here
LRS replicates data only within a single datacenter in the primary region, so it does not provide a readable secondary copy if the primary region becomes unavailable.
★ When this WOULD be the correct answer
If the question specifies that cost is the primary concern and the data does not need to be available in case of a regional disaster, LRS would be the correct choice.
Why candidates choose this
Candidates may choose LRS because it is the cheapest option and they overlook the requirement for readable secondary copy during a regional outage.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse GRS with RA-GRS, assuming that geo-redundant replication automatically provides readable secondary copies, but GRS does not allow read access to the secondary region until a failover occurs, whereas RA-GRS explicitly enables read access at all times.
Detailed technical explanation
How to think about this question
RA-GRS uses asynchronous replication to a paired secondary region, typically with a lag of minutes (RPO of 15 minutes or less). The secondary endpoint (e.g., `https://<storage-account>-secondary.blob.core.windows.net`) is always available for reads, but data may not be fully consistent due to the asynchronous nature. In a real-world scenario, if the primary region suffers a prolonged outage, RA-GRS allows immediate read access to the last replicated state, while GRS requires a manual or Microsoft-initiated failover to promote the secondary to primary before reads are possible.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
