AB-900 Microsoft 365 Copilot & Agent Administration Fundamentals Study Prep

a site member of

The correct answer is a site member of . In the exhibit, the Site members group for Site1 contains Everyone except external users with Edit permissions. Microsoft documents that “Everyone except external users” automatically includes all internal users and excludes external guests . Since User1 is a newly created user in the organization, User1 is an internal user and is therefore included in that built-in principal.

Because that built-in principal is placed in the Site members group, User1 inherits member-level access to the site. User1 is not a site owner, because the Site owners group contains only the Global Administrator entry shown in the exhibit. User1 is also not merely a visitor, because the Site visitors group is listed as None . Finally, User1 is not prevented from accessing the site, because the membership granted through Everyone except external users gives internal users access to the site according to the permissions assigned to that group.

the Microsoft Authenticator app

The correct answer is the Microsoft Authenticator app . The image shows the familiar Microsoft MFA prompt that says “Are you trying to sign in?” and “Enter the number shown to sign in.” Microsoft documents this as number matching in Authenticator push notifications , which is part of Microsoft Entra multifactor authentication using the Microsoft Authenticator app . Microsoft explains that number matching is a security improvement for Authenticator push approvals and is used when the default sign-in method is Authenticator push notifications.

The other choices do not match the experience shown. Email OTP would involve a one-time code sent by email. SMS would send a text message code to a phone number. Temporary Access Pass is a time-limited passcode used for onboarding or recovery scenarios, not the mobile push screen shown in the image. Because the graphic specifically shows a mobile approval prompt with number matching, the MFA method is clearly the Microsoft Authenticator app .
