DP-300 Practice Question: Monitor, configure, and optimize database resources
You have an Azure SQL Database in the Hyperscale service tier. You need to ensure that read-only workloads are offloaded to a readable secondary. Which configuration should you set?
⚠ Common exam trap
A common mix-up: candidates confuse the `ReadScale` property (used in Premium tier) with the Hyperscale tier's always-on read-scale capability, or incorrectly think a failover group is required to enable read-only routing.

Correct answer & explanation
✓
Use ApplicationIntent=ReadOnly in the connection string.
Setting `ApplicationIntent=ReadOnly` in the connection string directs read-only workloads to a readable secondary replica in Azure SQL Database Hyperscale. This offloads read traffic from the primary, improving performance for write-heavy operations. The Hyperscale tier supports this feature without requiring a failover group or explicit read-scale configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set ReadOnlyRouting=1 on the database.
Why it's wrong here
ReadOnlyRouting is not a database setting.
- ✗
Add the database to a failover group.
Why it's wrong here
Failover groups provide geo-replication, not read routing.
- ✗
Set ReadScale to 1 on the database.
Why it's wrong here
ReadScale is set at server level.
- ✓
Use ApplicationIntent=ReadOnly in the connection string.
Why this is correct
This routes queries to a readable secondary.
