- A
Disable sharing of the app with external users.
Why wrong: This prevents the business requirement of allowing external access.
- B
Create a new environment specifically for external users with only the required data.
This isolates the sensitive data and provides controlled access.
- C
Add external users as guests in Microsoft Entra ID and grant them access to the existing environment.
Why wrong: This exposes sensitive data to external users in the same environment.
- D
Use DLP policies to block all connectors except the canvas app.
Why wrong: DLP policies do not prevent external users from accessing data within Dataverse.
Question 384 of 976
Isolating External Guests in a Separate Environment
This PL-900 practice question tests your understanding of manage the microsoft power platform environment. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A company uses Microsoft Power Platform and wants to allow external users (guests) to access a canvas app. The app connects to a Dataverse database that contains sensitive customer information. The security team is concerned about data leakage. What should the administrator do to minimize risk?
Clue words in this question

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
✓
Create a new environment specifically for external users with only the required data.
Option B is correct because creating a separate environment for external users allows the administrator to control exactly which Dataverse tables and data are exposed, minimizing the risk of sensitive customer information being leaked. This approach follows the principle of least privilege by isolating guest access to a sandboxed environment with only the required data, rather than granting access to the existing production environment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Add external users as guests in Microsoft Entra ID and grant them access to the existing environment.
Why it's wrong here

Why it's wrong here
DLP policies do not prevent external users from accessing data within Dataverse.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume adding guests via Microsoft Entra ID and applying DLP policies is sufficient, but they overlook that guests in the same environment inherit the same Dataverse database access unless explicitly restricted, which is harder to manage and audit than a dedicated environment.
Detailed technical explanation
How to think about this question
Under the hood, Power Platform environments are isolated containers with their own Dataverse database, security roles, and data policies. By provisioning a separate environment for external users, the administrator can use Dataverse column-level security and table permissions to expose only a subset of data, such as a filtered view or a dedicated table with non-sensitive fields. This aligns with the Microsoft Zero Trust model, where access is explicitly scoped and verified, and avoids the risk of accidental data exposure through cross-environment queries or shared security groups.
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 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.
