DP-300 Plan and implement data platform resources Practice Question
You are designing a data platform for a global SaaS company. The application requires a relational database that can handle up to 50 TB of data and supports high-frequency inserts. The database must be able to scale compute independently from storage and provide fast restores (within minutes) for large databases. Which Azure SQL offering should you choose?
⚠ Common exam trap
Candidates often confuse the Business Critical tier's high availability and performance features with the ability to handle large data volumes and fast restores, overlooking the strict 4 TB size limit and lack of compute/storage decoupling.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure SQL Database Hyperscale tier
The Hyperscale tier of Azure SQL Database is designed for workloads up to 100 TB, decouples compute from storage (allowing independent scaling), and uses a log-based architecture with page servers to enable fast restores (typically within minutes, regardless of database size). This directly matches the requirements for 50 TB data, high-frequency inserts, independent compute/storage scaling, and rapid restore times.
