- A
Use Azure Data Factory with a Copy activity to load data into a staging table, then use a Data Flow activity to perform upserts.
Why wrong: Data Flow can be used but may be overkill; also partitioning not addressed.
- B
Use Azure Databricks to read the CSV files, perform upserts, and write to the dedicated SQL pool using JDBC.
Why wrong: Adds complexity and cost.
- C
Use PolyBase to create external tables on the CSV files and then use CREATE TABLE AS SELECT to load into the dedicated SQL pool.
Why wrong: Does not handle upserts or late-arriving data.
- D
Use Azure Data Factory with a Copy activity to load data into a staging table in the dedicated SQL pool, then use a Stored Procedure activity to merge the data into the final table.
Handles upserts and late-arriving data effectively.
Quick Answer
The correct approach is to use Azure Data Factory with a Copy activity to load data into a staging table, then a Stored Procedure activity to merge the data into the final table. This pattern handles late-arriving batch files in Azure Synapse by first isolating incoming data in a staging area, then applying a MERGE statement that performs upserts—inserting new records and updating existing ones—so that even if a file arrives after the scheduled processing time, the final table remains consistent without duplicates or data loss. On the DP-203 exam, this scenario tests your understanding of incremental loading and data consistency patterns, often appearing as a trap where candidates choose PolyBase (which lacks native upsert support) or over-engineer with Databricks. Remember: staging absorbs the delay, merge resolves the conflict. A useful memory tip is “Stage then Merge—late files won’t diverge.”
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 processing solution for a retail company that uses Azure Synapse Analytics. The solution must process point-of-sale (POS) data from multiple stores. The data arrives in CSV files in Azure Data Lake Storage Gen2. Each store sends a file every hour. You need to process the files as they arrive and load the data into a dedicated SQL pool. The solution must handle late-arriving files (files that arrive after the scheduled processing time) and ensure that the data is consistent. Which approach 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 Data Factory with a Copy activity to load data into a staging table in the dedicated SQL pool, then use a Stored Procedure activity to merge the data into the final table.
Option D is correct because using a stored procedure with merge logic can handle upserts and late-arriving data. Azure Data Factory can execute the stored procedure after copying data to a staging table. Option A is wrong because PolyBase with external tables does not handle upserts well. Option B is wrong because Azure Databricks would be overkill for this scenario. Option C is wrong because partitioning alone does not handle late-arriving data.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
