PL-300 Manage and secure Power BI Practice Question

This PL-300 practice question tests your understanding of manage and secure power bi. 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.

You manage a Power BI environment where users create reports using data from Azure SQL Database. You need to enforce that all data sources use Single Sign-On (SSO) with Microsoft Entra ID. What should you do?

A
In the Power BI admin portal, block authentication methods other than OAuth2.
Blocking non-OAuth methods forces SSO.
B
Configure the dataset to use SSO in the Power BI service.
Why wrong: You cannot block other methods at the dataset level.
C
Enable the 'Allow data sources to use SSO' tenant setting.
Why wrong: This setting allows SSO but does not block other methods.
D
Create a security group for SSO-enabled data sources and assign it to the workspace.
Why wrong: Security groups do not enforce SSO.

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

✓

In the Power BI admin portal, block authentication methods other than OAuth2.

Option A is correct because by blocking authentication methods other than OAuth2 in the Power BI admin portal, you force all data sources to use OAuth2, which is required for SSO with Microsoft Entra ID. This ensures that no data source can use other authentication methods, effectively enforcing SSO for all supported sources. Option B is incorrect because configuring a dataset to use SSO only applies to that specific dataset, not all data sources across the environment. Option C is incorrect because enabling the 'Allow data sources to use SSO' tenant setting permits SSO but does not block other authentication methods; it does not enforce SSO. Option D is incorrect because creating a security group does not enforce SSO; it is used for managing access, not for blocking authentication methods.

Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Common exam traps

Common exam trap: ACLs stop at the first match

ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.

Detailed technical explanation

How to think about this question

ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.

KKey Concepts to Remember

Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.

TExam Day Tips

Check inbound versus outbound direction.
Read the ACL from top to bottom.
Look for a broader permit or deny above the intended line.

Key takeaway

ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

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.

What to study next

Got this wrong? Here's your next step.

Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PL-300 ACL questions on filtering logic and placement.
