Question 254 of 846
Secure, monitor, and optimize data storage and data processing →hardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is that all files from all subfolders will be copied into a single folder in the sink. This behavior occurs because the Copy activity is configured with recursive: true, which instructs the activity to traverse all subdirectories within the source folder, and FlattenHierarchy, which writes every file directly into the sink without preserving any of the original folder structure. On the Microsoft Azure Data Engineer Associate DP-203 exam, this combination tests your understanding of how Azure Data Factory copy activity recursive FlattenHierarchy behavior interacts—a common trap is assuming FlattenHierarchy maintains subfolder paths or that recursive defaults to false. Remember, recursive digs deep, while FlattenHierarchy flattens the tree; together they create a single-level output. Memory tip: think "Recursive retrieves, FlattenHierarchy flattens"—if you see both, expect a flat sink.

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.

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

✓

All files from all subfolders will be copied into a single folder in the sink.

Option B is correct because recursive: true ensures all files from subfolders are copied, and FlattenHierarchy writes them to the sink without preserving the folder structure. Option A is wrong because recursive is true. Option C is wrong because FlattenHierarchy does not preserve structure. Option D is wrong because staging is disabled.

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 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.
