Question 225 of 760
DP-203 Develop data processing Practice Question
You are developing a data processing pipeline in Azure Synapse Analytics that uses a SQL script to transform data in a dedicated SQL pool. The pipeline currently runs in the built-in serverless pool, but you want to migrate it to a dedicated SQL pool for better performance. What must you change in the pipeline?
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
✓
Modify the SQL script to use T-SQL compatible with dedicated SQL pool.
Dedicated SQL pool uses T-SQL that has specific syntax differences from the serverless SQL pool used in Azure Synapse Analytics. When migrating from serverless to dedicated, you need to modify your SQL script to be compatible with dedicated SQL pool's T-SQL (e.g., different supported functions, data types, and performance features). Option A (changing the linked service) might also be necessary as part of the migration but is not the primary change needed to ensure the script runs correctly. Option B (replacing with Mapping Data Flow) is not required; the script itself can still be used. Option C (self-hosted IR) is not relevant for SQL script activities in Synapse pipelines.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the linked service from serverless to dedicated SQL pool.
Why it's wrong here
While the linked service needs updating, the SQL script itself may also need changes; the primary change is the script.
- ✗
Replace the SQL script with a Mapping Data Flow activity.
Why it's wrong here
Data Flow is an alternative but not required; the script can still work with modifications.
- ✗
Update the integration runtime to a self-hosted IR.
Why it's wrong here
Integration runtime is for connectivity, not for SQL script compatibility.
- ✓
Modify the SQL script to use T-SQL compatible with dedicated SQL pool.
Why this is correct
Dedicated SQL pool has a different T-SQL surface area; some functions may need to be rewritten.
