Question 400 of 904
PL-900 Practice Question: Manage the Microsoft Power Platform environment
A company plans to deploy Power Apps for field service technicians. The IT department requires that all users authenticate using their corporate credentials and that access to the Power Apps environment is restricted to users from the company's tenant only. Which configuration should the administrator use?
⚠ Common exam trap
Test-takers frequently confuse user-level security groups with tenant-level access controls, mistakenly thinking that assigning a specific security group (Option C) alone is sufficient to block external users, when in fact the environment's tenant restriction setting is required to prevent cross-tenant authentication entirely.
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
✓
Set the environment security group to 'Only internal users' and disable external sharing
Setting the environment security group to 'Only internal users' and disabling external sharing ensures that only authenticated users from the company's own Microsoft Entra ID (formerly Azure AD) tenant can access the Power Apps environment. This meets the IT requirement of restricting access to corporate credentials and the company's tenant only, preventing any external guest or user from another tenant from signing in.
