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 in Azure Data Factory that uses mapping data flows. You need to perform type conversions on incoming data. Which three transformations can be used to change data types? (Choose three.)
Conditional Split
Why wrong: Conditional Split routes rows based on conditions, not type conversion.
Derived Column
Derived Column allows type conversion via expressions.
Assert
Assert can validate and convert data types.
Sort
Why wrong: Sort does not change data types.
Select
Select can cast columns to different types.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Derived Column
Options A, B, and C are correct. Derived Column can change types via expressions. Select can cast columns during projection. Assert can check and convert types. Option D is wrong because Sort only orders data. Option E is wrong because Conditional Split routes rows based on conditions, not type conversion.
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.
Conditional Split
Why it's wrong 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.
