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
✓
Azure AD B2C
Azure AD B2C (Business-to-Consumer) is the identity provider that supports social identity providers like Google, Facebook, and Microsoft accounts. It allows external users to register using their social media accounts. Local authentication is for username/password within the site, not social accounts. Microsoft Entra ID is for organizational accounts. Microsoft account is a single social provider, but Azure AD B2C is the configured identity provider that can integrate multiple social providers.
Answer analysis
Option-by-option breakdown
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
Azure AD B2C is the external identity provider that supports social sign-in (Google, Facebook, etc.) for Power Pages, satisfying the requirement that external users register with their own social media accounts. Microsoft Entra ID handles workforce identities, not consumer self-registration. Note: Azure AD B2C is the legacy name; Microsoft Entra External ID is its successor.
- ✗
Local authentication
Why it's wrong here
Local authentication issues its own username and password stored in Dataverse, so it cannot accept social media credentials from external users. It is tempting because it requires no identity provider configuration, and it would be correct when visitors should create site-specific accounts rather than sign in with an existing social identity.
- ✗
Microsoft Entra ID
Why it's wrong here
Microsoft Entra ID authenticates work or school accounts from an organisation's directory, not personal social media accounts, so external users cannot register with Facebook or Google credentials. It is tempting because it is the default Power Pages provider, and it would be correct for internal employee or partner access using organisational accounts.
- ✗
Microsoft account
Why it's wrong here
Microsoft account covers consumer logins for Microsoft services such as Outlook.com, not third-party social providers like Facebook, Twitter or LinkedIn, so it cannot meet the social registration requirement. It is tempting because it is a consumer identity option, and it would be correct when visitors should sign in specifically with their personal Microsoft credentials.
