Quick Answer
The correct answer is to use a self-hosted integration runtime and increase the copy activity timeout. This is because a self-hosted IR is required to connect Azure Data Factory to on-premises SQL Server, and the default timeout of 7 days may still be insufficient for a 50 GB load if network latency or resource contention causes delays; explicitly increasing the timeout ensures the copy activity does not fail prematurely. On the DP-203 exam, this scenario tests your understanding of connectivity requirements for hybrid data movement and the distinction between timeout errors and performance tuning—a common trap is choosing to split data into smaller chunks, which helps with parallelism but does not directly resolve a timeout error caused by the activity exceeding its allowed duration. Remember the memory tip: “On-prem needs self-host; timeouts need a longer post.”
This DP-203 practice question tests your understanding of develop data processing. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Your company uses Azure Data Factory to load data from an on-premises SQL Server database to Azure Synapse Analytics. The pipeline runs daily and the load volume is about 50 GB per run. Recently, the pipeline started failing with timeout errors during the copy activity. You need to ensure reliable data transfer. What should you do?
Use a self-hosted integration runtime and increase the copy activity timeout
Self-hosted IR connects to on-premises; increasing timeout prevents failures.
Use PolyBase to load data in parallel
Why wrong: PolyBase is a loading method, not a fix for timeout.
Split the copy into multiple smaller activities
Why wrong: Not the most direct solution.
Switch to Azure Integration Runtime
Why wrong: Azure IR cannot access on-premises data directly.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use a self-hosted integration runtime and increase the copy activity timeout
Option B (Use a self-hosted integration runtime and increase the timeout) is correct because a self-hosted IR is required for on-premises sources, and increasing the timeout can handle larger volumes. Option A (Use Azure Integration Runtime) does not connect to on-premises. Option C (Use PolyBase) is for loading into Synapse but does not address the connectivity or timeout. Option D (Split the data into smaller chunks) might help but is not the primary solution; increasing timeout is more direct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
