The answer is Azure SQL Database Hyperscale with geo-replication, because it uniquely delivers geo-distributed reads with low latency for global users while maintaining a single write endpoint for your critical OLTP workload. Hyperscale’s distributed architecture separates compute from storage, allowing you to add read-scale replicas in multiple regions that asynchronously replicate from a primary writable endpoint, ensuring users in North America, Europe, and Asia experience fast, local reads without compromising write consistency. On the DP-300 exam, this scenario tests your ability to differentiate between Hyperscale’s read scale-out and other options like failover groups or elastic pools—a common trap is confusing geo-replication’s readable secondaries with the single-writer requirement of a global application. Remember the memory tip: “Hyperscale reads spread, writes stay single” to quickly recall that only Hyperscale with geo-replication satisfies both low-latency reads and a single write endpoint.
DP-300 Plan and implement data platform resources Practice Question
This DP-300 practice question tests your understanding of plan and implement data platform resources. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
You are designing a new Azure SQL Database for a critical OLTP workload. The database will be used by a global application with users in North America, Europe, and Asia. The primary requirement is low-latency reads for all regions. You need to choose a deployment option that supports geo-distributed reads and provides a single write endpoint. Which option should you select?

Correct answer & explanation
✓
Azure SQL Database Hyperscale with geo-replication
Azure SQL Database Hyperscale with geo-replication is the correct choice because it provides a single writable primary endpoint while supporting geo-distributed readable secondaries with low-latency reads for global users. Hyperscale's distributed architecture allows fast scaling and read scale-out, and geo-replication enables asynchronous replication to multiple regions, meeting the OLTP workload's low-latency read requirement without compromising the single write endpoint.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure SQL Database with active geo-replication
Why it's wrong here
Active geo-replication supports only one readable secondary region.
✗
Azure SQL Managed Instance with failover groups
Why it's wrong here
Failover groups for Managed Instance do not provide readable secondaries.
✗
Azure SQL Database with failover groups
Why it's wrong here
Failover groups only support one readable secondary region.
✓
Azure SQL Database Hyperscale with geo-replication
Why this is correct
Hyperscale geo-replication supports multiple readable secondaries across regions.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse active geo-replication (Option A) with failover groups (Option C), not realizing that Hyperscale's geo-replication (Option D) is the only option that combines a single write endpoint with the distributed read scale-out needed for global low-latency reads.
Detailed technical explanation
How to think about this question
Hyperscale's architecture decouples compute from storage, allowing multiple readable replicas to be created in different Azure regions with minimal overhead, as each replica accesses the same shared page server set. Geo-replication in Hyperscale uses asynchronous log shipping to maintain consistency, and the failover group provides a single write endpoint via a listener, while read-only routing can direct traffic to the nearest secondary replica. In a real-world scenario, a global e-commerce platform can use this to serve product catalog reads from local replicas while ensuring all writes go to the primary region, keeping latency under 10 ms for most users.

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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
