This PL-900 practice question tests your understanding of demonstrate the capabilities of power pages. 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.
Which TWO authentication providers are natively supported by Power Pages for external user access?
Azure AD B2C
Supports social and local accounts.
Microsoft Entra ID
Why wrong: For organizational users.
Why wrong: Not natively supported.
Why wrong: Not natively supported; requires custom setup.
Local authentication
Built-in username/password.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure AD B2C
Options B and D are correct. Azure AD B2C and local authentication are natively supported. Option A is wrong because Microsoft Entra ID is for internal users. Option C is wrong because Facebook is not a native provider. Option E is wrong because Google is not a native provider.
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.
Azure AD B2C
Why this is correct
Supports social and local accounts.
Related concept
Static NAT maps one inside address to one outside address.
Microsoft Entra ID
Why it's wrong here
For organizational users.
Why it's wrong here
Not natively supported.
Why it's wrong here
Not natively supported; requires custom setup.
Local authentication
Why this is correct
Built-in username/password.
Related concept
Static NAT maps one inside address to one outside address.
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.
