Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company stores critical customer data in Azure Blob Storage. The compliance team requires that the data remains available for read operations even if the primary Azure region experiences a complete outage. They plan to use an Azure storage redundancy option that automatically replicates data to a secondary region and allows read access from that secondary region during an outage, without requiring any manual failover action. Which storage redundancy option should they configure on the storage account?
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 replicates data three times within a single datacenter in the primary region. It does not protect against a regional outage, so it does not meet the requirement.
B
Distractor review
Zone-redundant storage (ZRS)
ZRS replicates data synchronously across three Azure availability zones within the primary region. While it provides resilience within the region, it does not protect against a complete region outage.
C
Distractor review
Geo-redundant storage (GRS)
GRS replicates data to a paired secondary region for regional disaster recovery, but read access to the secondary region is not enabled by default. To read data from the secondary region during an outage, a manual failover must be initiated, which does not satisfy the requirement for automatic read access.
D
Best answer
Read-access geo-redundant storage (RA-GRS)
RA-GRS replicates data to a paired secondary region and provides read-only access to the secondary endpoint at all times. During a primary region outage, data can still be read from the secondary region without any manual action, meeting the compliance 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.

Question 6
A company develops a web API that runs on Azure App Service. The development team wants to deploy a new version of the API to a staging environment, run integration tests against it, and then gradually shift production traffic to the new version.

FAQ
Questions learners often ask
What does this AZ-900 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-redundant storage (RA-GRS) — Read-access geo-redundant storage (RA-GRS) is the correct choice because it replicates data to a paired secondary region and provides read-only access to the secondary region endpoint during an outage. This meets the requirement of continuous read availability without manual intervention. Locally-redundant storage (LRS) replicates within a single datacenter and is not resilient to a regional failure. Zone-redundant storage (ZRS) replicates across availability zones within the same region, still vulnerable to a full region outage. Geo-redundant storage (GRS) replicates to a secondary region but does not allow read access during an outage unless a manual failover is initiated.
