The correct choice is to configure the Copy activity to use staging with Azure Blob Storage and then use a stored procedure for bulk insert. This approach reduces DTU consumption on Azure SQL Database by offloading the heavy data transformation and movement to the staging blob, allowing the database to ingest data in efficient batches rather than processing each row individually through the pipeline. On the DP-203 exam, this scenario tests your understanding of how to optimize data movement without scaling resources—a common trap is confusing PolyBase, which is designed for Azure Synapse Analytics, not Azure SQL Database. Remember that staging with blob storage shifts the compute load away from the database, directly addressing the goal to reduce DTU consumption in ADF copy to Azure SQL Database. A useful memory tip: “Stage it, then bulk load it—don’t let the database choke on every row.”
DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and 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 optimizing an Azure Data Factory pipeline that moves data from Azure Blob Storage to Azure SQL Database. The pipeline currently uses a Copy activity with a staging setting enabled. You notice high DTU consumption on the Azure SQL Database during the copy operation. How can you reduce the impact on the source database?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure the Copy activity to use staging with Azure Blob Storage and then use a stored procedure to bulk insert.
Option B is correct because using PolyBase in Azure Synapse Analytics (not SQL Database) is for bulk loads, but the target is Azure SQL Database. Actually, the correct approach is to use staging copy with Azure Blob Storage as staging and then use PolyBase? Wait, the target is Azure SQL Database, not Synapse. For SQL Database, using a staging blob and then bulk insert can reduce DTU consumption. But among options, Option A (increase DTU) is scaling, not reduction. Option B (use PolyBase) is for Synapse. Option C (use staging copy with Azure Blob Storage and then use bulk insert) is correct. Option D (use parallel copy) increases throughput but also DTU. So correct is C.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Configure the Copy activity to use staging with Azure Blob Storage and then use a stored procedure to bulk insert.
Why this is correct
Staging allows the copy to offload transformation to Blob Storage, and bulk insert reduces DTU consumption.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use PolyBase to load data directly from Blob Storage to Azure SQL Database.
Why it's wrong here
PolyBase is not supported in Azure SQL Database; it is for Azure Synapse.
✗
Enable parallel copy in the Copy activity settings.
Why it's wrong here
Parallel copy increases throughput but also increases DTU consumption.
✗
Increase the DTU of the Azure SQL Database to handle the load.
Why it's wrong here
Increasing DTU adds cost but does not reduce impact on the source; it helps the target.
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.

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.
