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 a Power BI administrator. A user reports that their scheduled data refresh fails with error 'The data source credentials are no longer valid.' The dataset uses a SQL Server database with Windows authentication. What should you do first to resolve the issue?

Clue words in this question

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

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

A
Reinstall the on-premises data gateway on the server.
Why wrong: Reinstalling the gateway is unnecessary; the issue is credential-related.
B
Reassign the dataset to a different Premium capacity.
Why wrong: Capacity assignment does not affect credential validity.
C
Modify the dataset to use 'Impersonate the authenticated user' for data sources.
Why wrong: Impersonation is for web-based data sources, not Windows authentication.
D
Ask the user to update the data source credentials in the Power BI service dataset settings.
Windows credentials may expire; updating them in the service resolves the error.

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

✓

Ask the user to update the data source credentials in the Power BI service dataset settings.

Option D is correct. The error 'The data source credentials are no longer valid' typically occurs when the password has changed or expired. The user can update the credentials in the dataset settings in the Power BI service. Option A is incorrect because the on-premises data gateway is not the issue; a reinstall is unnecessary. Option B is incorrect because reassigning the dataset to a different Premium capacity does not address credential validity. Option C is incorrect because using 'Impersonate the authenticated user' still requires valid credentials and does not fix the problem.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
