Prepare the data →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is Private. This is correct because the JSON data source configuration explicitly defines the property "privacyLevel":"Private", which in Power BI restricts that source from being combined with data from any other source during query folding, preventing unintended cross-source data exposure. On the Microsoft Power BI Data Analyst PL-300 exam, this concept tests your ability to read and interpret data source configuration JSON files, a common task when troubleshooting or auditing data connections. A frequent trap is confusing Private with Organizational, but remember: Private isolates the source completely, while Organizational allows combining within the same tenant. For a quick memory tip, think of Private as a "data silo" — it keeps your data locked away from all other sources, just like a private room keeps conversations separate.

PL-300 Prepare the data Practice Question

This PL-300 practice question tests your understanding of prepare the data. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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

✓

Private

The privacy level setting for the data source 'SalesData' is 'Private' because the JSON snippet shows the property "privacyLevel":"Private". In Power BI, the Private privacy level restricts data from being combined with data from other sources, ensuring that sensitive data is not inadvertently shared across queries. This setting is explicitly defined in the data source configuration and is not Organizational, None, or Public.

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

The trap here is that candidates may confuse the 'Private' privacy level with the 'Organizational' level, thinking that data within the same organization is automatically safe to combine, but the JSON explicitly shows 'Private', which is the most restrictive setting.

Trap categories for this question

  • Command / output trap

    The JSON shows Private, not Organizational.

Detailed technical explanation

How to think about this question

Power BI's privacy levels (Private, Organizational, Public) are enforced at the data source level within the Mashup engine (Power Query) to control data leakage across queries. The Private level prevents any cross-source data combination, even within the same Power BI Desktop file, which is critical when dealing with sensitive data like PII or financial records. Under the hood, this setting is stored in the DataSource metadata and is evaluated during query folding and data loading to ensure compliance with data protection policies.

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.

TExam Day Tips

  • 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.
