DP-300 Plan and implement data platform resources Practice Question
Your company is planning to deploy a new application that uses Azure SQL Database with a Hyperscale service tier. The application requires near-instantaneous scaling of compute resources without downtime. The database will handle large data volumes (over 10 TB). Additionally, the application team wants to use the latest database features, including JSON support and graph queries. Which considerations should you evaluate before choosing Hyperscale?
⚠ Common exam trap
Candidates often assume Hyperscale supports all features of other tiers due to its advanced capabilities, but Microsoft specifically excludes cross-database and elastic queries in Hyperscale, making it a common oversight in exam questions.

Correct answer & explanation
✓
Hyperscale does not support cross-database queries or elastic queries.
Azure SQL Database Hyperscale does not support cross-database queries or elastic queries. This limitation is critical for the application team if they need to query across multiple databases in a single query, which is a common requirement for distributed applications. The Hyperscale architecture separates compute from storage, making cross-database query capabilities unavailable, unlike other service tiers such as General Purpose or Business Critical.
