- A
Use Azure Synapse Analytics dedicated SQL pool as the sink dataset and use the Copy activity with PolyBase enabled.
Why wrong: PolyBase alone does not handle incremental upserts; a stored procedure with merge logic is needed.
- B
Use Azure Synapse Analytics dedicated SQL pool as the sink dataset and enable the built-in Upsert option.
Why wrong: The built-in Upsert option is not available for dedicated SQL pool in ADF copy activity.
- C
Use Azure Blob Storage as the sink dataset, then use PolyBase to load into the dedicated SQL pool.
Why wrong: This adds an unnecessary intermediate step and does not provide built-in incremental loading.
- D
Use Azure Synapse Analytics dedicated SQL pool as the sink dataset and use Stored Procedure with staging table and PolyBase.
This combination enables high-throughput ingestion and supports incremental loading via merge logic in the stored procedure.
Quick Answer
The answer is to use Azure Synapse Analytics dedicated SQL pool as the sink dataset with a Stored Procedure that leverages a staging table and PolyBase. This combination is correct because PolyBase enables high-throughput parallel loading directly into the staging table, while the stored procedure handles the merge logic—typically an upsert—to efficiently manage incremental changes without reloading the entire dataset. On the DP-203 exam, this scenario tests your understanding of optimizing data movement for large-scale, daily incremental loads, and it often appears as a distractor where candidates mistakenly choose a simple Copy Activity without staging. A common trap is assuming that native table copy or bulk insert alone is sufficient, but PolyBase’s parallel architecture is essential for performance in Synapse. Remember the memory tip: “Stage with PolyBase, merge with a proc” to recall that staging enables high-speed ingestion and the stored procedure handles the incremental logic.
DP-203 Develop data processing Practice Question
This DP-203 practice question tests your understanding of develop data processing. 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 data pipeline in Azure Data Factory (ADF) that copies data from an on-premises SQL Server database to Azure Synapse Analytics dedicated SQL pool. The pipeline must run daily and handle incremental loads efficiently. Which sink dataset type and copy method should you use?
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
Use Azure Synapse Analytics dedicated SQL pool as the sink dataset and use Stored Procedure with staging table and PolyBase.
Option D is correct because it uses a staging table and PolyBase to efficiently load incremental data into Azure Synapse Analytics dedicated SQL pool. PolyBase provides high-throughput parallel loading, and the stored procedure handles the merge logic (upsert) to manage incremental changes. This approach is recommended for large-scale, daily incremental loads to Synapse.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume the built-in Upsert option works for all Azure SQL targets, but it is not supported for Azure Synapse Analytics dedicated SQL pool, requiring a custom staging-and-merge pattern instead.
Detailed technical explanation
How to think about this question
PolyBase uses the T-SQL CREATE EXTERNAL TABLE AS SELECT (CETAS) or INSERT...SELECT pattern to load data in parallel from staging files. In this design, the stored procedure typically performs a MERGE statement to apply inserts and updates from the staging table to the target table, ensuring idempotent incremental loads. This pattern also allows for error handling and retry logic within the stored procedure, which is critical for production pipelines.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
