Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A global e-commerce platform requires a database that supports multi-region writes with automatic conflict resolution and single-digit millisecond latency for reads and writes from any region. The application uses a flexible schema with JSON documents. They also need to enforce strong consistency for critical operations (e.g., order placement) while allowing eventual consistency for less critical reads. Which Azure data service and configuration 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
Best answer
Azure Cosmos DB with multi-region writes enabled on the account, using the SQL (Core) API, and applying strong consistency for the order placement operation via RequestOptions.
Cosmos DB supports multi-region writes with automatic conflict resolution, multiple consistency levels (strong, bounded staleness, session, consistent prefix, eventual), and the SQL API works with JSON documents. Strong consistency can be requested per request.
B
Distractor review
Azure SQL Database with active geo-replication across two regions and failover groups.
Azure SQL Database active geo-replication only allows one writable primary; the secondaries are read-only. It does not support multi-region writes or automatic conflict resolution.
C
Distractor review
Azure Cache for Redis with geo-replication.
Azure Cache for Redis is a caching layer, not a durable primary database. It can be used for low-latency reads but does not provide strong consistency or multi-region writes for persistence.
D
Distractor review
Azure Table Storage with geo-redundant storage (GRS) and read-access (RA-GRS).
Azure Table Storage does not support multi-region writes; only one region can accept writes. It also lacks automatic conflict resolution and offers only strong consistency within a region.
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-305 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Cosmos DB with multi-region writes enabled on the account, using the SQL (Core) API, and applying strong consistency for the order placement operation via RequestOptions. — Azure Cosmos DB with multi-region writes and the ability to use multiple consistency levels (including strong and eventual) meets all requirements. The SQL API supports JSON documents. Multi-region writes with automatic conflict resolution are a key feature. For strong consistency, you must configure the account with bounded staleness or strong at the cost of latency. Other options: Azure SQL DB supports active geo-replication but only one region can accept writes. Azure Cache for Redis is not a durable database. Azure Table Storage does not support multi-region writes or conflict resolution.
