Quick Answer
The answer is Microsoft Entra ID because it is the dedicated authentication provider for organizational users in Power Pages, enabling access control based on your company’s directory. Microsoft Entra ID (formerly Azure AD) handles identity verification for employees and internal partners, allowing you to restrict specific pages to authenticated users from your organization through built-in security groups and policies. On the PL-900 exam, this question tests your understanding of which identity provider maps to which audience—Entra ID for internal users, Azure AD B2C for customers, and local auth for anonymous or generic access. A common trap is confusing Entra ID with Azure AD B2C, but remember: “Internal = Entra, External = B2C.” For a quick memory tip, think “Entra ID for employees, B2C for everyone else.”
This PL-900 practice question tests your understanding of demonstrate the capabilities of power pages. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 need to restrict access to a specific page on a Power Pages site to only authenticated users from your organization. Which authentication provider should you configure?
Microsoft Entra ID
Entra ID authenticates organizational users.
Why wrong: LinkedIn is not a supported identity provider.
Azure AD B2C
Why wrong: B2C is for external users.
Local authentication
Why wrong: Local auth doesn't restrict to your organization.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Microsoft Entra ID
Option A is correct because Microsoft Entra ID is used for organizational identity. Option B is wrong because Azure AD B2C is for external identities. Option C is wrong because local authentication is for generic users. Option D is wrong because LinkedIn is not supported natively.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Microsoft Entra ID
Why this is correct
Entra ID authenticates organizational users.
Related concept
Static NAT maps one inside address to one outside address.
Why it's wrong here
LinkedIn is not a supported identity provider.
Azure AD B2C
Why it's wrong here
B2C is for external users.
Local authentication
Why it's wrong here
Local auth doesn't restrict to your organization.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PL-900 NAT questions on configuration and troubleshooting.

Variation 1. An organization needs to allow external vendors to log in to a Power Pages site using their existing Microsoft Entra ID accounts. What authentication provider should be configured?
easyWhy A: Microsoft Entra ID (formerly Azure AD) is the correct provider for organizational accounts. The local provider is for internal users. OAuth 2.0 is a protocol, not a provider name. 'Microsoft Account' is for personal accounts.
