Actual exam question from Microsoft's AZ-303

Question #: 9
Topic #: 5

You configure Azure AD Connect for Azure Active Directory Seamless Single Sign-On (Azure AD Seamless SSO) for an on-premises network.
Users report that when they attempt to access myapps.microsoft.com, they are prompted multiple times to sign in and are forced to use an account name that ends with onmicrosoft.com.
You discover that there is a UPN mismatch between Azure AD and the on-premises Active Directory.
You need to ensure that the users can use single-sign on (SSO) to access Azure resources.
What should you do first?

A. From on-premises network, deploy Active Directory Federation Services (AD FS).
B. From Azure AD, add and verify a custom domain name.
C. From on-premises network, request a new certificate that contains the Active Directory domain name.
D. From the server that runs Azure AD Connect, modify the filtering options.

Show Suggested Answer

Suggested Answer: B 🗳️
The UPN is used by Azure AD to allow users to sign-in. The UPN that a user can use, depends on whether or not the domain has been verified. If the domain has been verified, then a user with that suffix will be allowed to sign-in to Azure AD.
To do so, you need to add and verify a custom domain in Azure AD before you can start syncing the users.

John is a user in contoso.com. You want John to use the on-premises UPN [email protected] to sign in to Azure after you have synced users to your Azure AD directory contoso.onmicrosoft.com. To do so, you need to add and verify contoso.com as a custom domain in Azure AD before you can start syncing the users. If the UPN suffix of John, for example contoso.com, does not match a verified domain in Azure AD, then Azure AD replaces the UPN suffix with contoso.onmicrosoft.com.

When UserPrincipalName (UPN)/Alternate Login ID suffix is not verified with the Azure AD Tenant, then Azure Active Directory replaces the UPN suffixes with the default domain name "onmicrosoft.com". https://docs.microsoft.com/bs-latn-ba/azure/active-directory/hybrid/tshoot-connect-objectsync#upn-suffix-is-not-verified-with-azure-ad-tenant https://docs.microsoft.com/en-us/azure/active-directory/users-groups-roles/domains-manage Answer is B

Custom domain state and UPN It is important to ensure that there is a verified domain for the UPN suffix. John is a user in contoso.com. You want John to use the on-premises UPN [email protected] to sign in to Azure after you have synced users to your Azure AD directory contoso.onmicrosoft.com. To do so, you need to add and verify contoso.com as a custom domain in Azure AD before you can start syncing the users. If the UPN suffix of John, for example contoso.com, does not match a verified domain in Azure AD, then Azure AD replaces the UPN suffix with contoso.onmicrosoft.com.
