PL-300 Deploy and maintain assets Practice Question

This PL-300 practice question tests your understanding of deploy and maintain assets. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 manage a Power BI workspace that contains a dataset refreshed daily from an on-premises SQL Server. Users report that the report shows data from two days ago. You verify that the scheduled refresh ran successfully this morning. What is the most likely cause?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

A
The gateway is using a cached version of the data due to a misconfigured data source.
A misconfigured gateway cache can cause stale data.
B
The refresh took longer than expected and timed out.
Why wrong: The refresh completed successfully, so timeout is not the issue.
C
The scheduled refresh is not set to refresh the dataset.
Why wrong: The refresh ran successfully, so scheduling is not the issue.
D
The on-premises data gateway is offline.
Why wrong: If the gateway were offline, the refresh would fail.

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 gateway is using a cached version of the data due to a misconfigured data source.

Option A is correct because the most likely cause is that the on-premises data gateway is using a cached version of the data due to a misconfigured data source. When the data source is misconfigured (e.g., incorrect credentials or connection string), the gateway may fall back to a previously cached dataset, causing the report to show stale data even though the scheduled refresh appears to have run successfully. This explains why users see data from two days ago despite a successful refresh this morning.

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 assume a successful refresh always means fresh data, but the gateway's caching behavior can mask a misconfigured data source, leading to stale data without an error.

Detailed technical explanation

How to think about this question

Under the hood, Power BI uses the on-premises data gateway to connect to SQL Server, and the gateway caches data source metadata and credentials. A misconfigured data source (e.g., stale credentials or an incorrect server name) can cause the gateway to use a cached snapshot instead of fetching fresh data, leading to a successful refresh status but outdated results. This behavior is distinct from a refresh failure and is a known pitfall when managing gateway data sources.

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.
