Which two scenarios are examples of using Microsoft Entra business-to-business (B2B) collaboration? (Choose two.)
B2B collaboration allows inviting external users from partner organizations.
Why this answer
Option A is correct because Microsoft Entra B2B collaboration allows you to invite external users from partner organizations to access your company's resources, such as a SharePoint Online site. The invited user authenticates using their own home tenant credentials, and a B2B guest user object is created in your directory to represent them.
Exam trap
The trap here is confusing B2B collaboration (inviting external business partners with work/school accounts) with B2C collaboration (allowing consumers to sign in with social identities like Facebook or Google), leading candidates to incorrectly select Option E.
