Your network contains an Active Directory domain named contoso.com.
You have a Microsoft 365 subscription.
You have a Microsoft Azure Active Directory (Azure AD) tenant named contoso.onmicrosoft.com.
You implement directory synchronization.
The developers at your company plan to build an app named App1. App1 will connect to the Microsoft Graph API to provide access to several Microsoft Office 365 services.
You need to provide the URI for the authorization endpoint that App1 must use.
What should you provide?
A . https://login.microsoftonline.com/
B . https://contoso.com/contoso.onmicrosoft.com/app1
C . https://login.microsoftonline.com/contoso.onmicrosoft.com/
D . https://myapps.microsoft.com
Answer: C
Explanation:
In a single tenant application, sign-in requests are sent to the tenant’s sign-in endpoint. For example, for contoso.onmicrosoft.com the endpoint would be: https://login.microsoftonline.com/ contoso.onmicrosoft.com. Requests sent to a tenant’s endpoint can sign in users (or guests) in that tenant to applications in that tenant.
