Question 774 of 966

Model the data →hardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is that the table will be refreshed with the same date range (2020-2025). This happens because the partition mode is set to 'import', not incremental refresh, so every dataset refresh fully replaces the entire table based on the static M code. Since the Power Query script generates dates from January 1, 2020 to December 31, 2025, no new dates beyond that range will appear once the date range expires—the code must be manually updated to extend the range. On the PL-300 exam, this tests your understanding of how import partition mode differs from incremental refresh, a common trap where candidates assume new data is automatically appended. Remember: import mode is a full reload, not an append. A helpful memory tip is “Import = In-place Replacement; Incremental = Intelligent Addition.”

This PL-300 practice question tests your understanding of model 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.

You are examining a Power BI model definition. The Date table is generated via Power Query M code. The partition mode is 'import'. What will happen when the dataset refreshes after December 31, 2025?

A
The existing table will be appended with new rows.
Why wrong: Import mode replaces the table.
B
The refresh will fail because EndDate is in the past.
Why wrong: Past dates are fine; M code will generate them.
C
The table will be refreshed with the same date range (2020-2025).
The M code defines a static range; refresh reloads that range.
D
New dates after 2025-12-31 will be added incrementally.
Why wrong: Incremental refresh not configured; partition mode is import.

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

✓

The table will be refreshed with the same date range (2020-2025).

Option C is correct. Since the partition mode is 'import' (not incremental), the entire table is replaced on each refresh. The M code generates dates from 2020-01-01 to 2025-12-31, so after 2025, no new dates will be added unless the code is updated. Option A is wrong because incremental refresh is not configured. Option B is wrong because the table is fully reloaded, not appended. Option D is wrong because the refresh will succeed, but no new dates beyond 2025 will appear.

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.
