You manage an Azure SQL database that allows for Azure AD authentication. You need to make sure that database developers can connect to the SQL database via Microsoft SQL Server Management Studio (SSMS). You also need to make sure the developers use their on-premises Active Directory account for authentication. Your strategy should allow for authentication prompts to be kept to a minimum. Which of the following should you implement? 

Answer options:

A. Azure AD token.
B. Azure Multi-Factor authentication.
C. Active Directory integrated authentication.
D. OATH software tokens.

C

Azure AD can be the initial Azure AD managed domain. Azure AD can also be an on-premises Active Directory Domain Services that is federated with the Azure AD. Using an Azure AD identity to connect using SSMS or SSDT The following procedures show you how to connect to a SQL database with an Azure AD identity using SQL Server Management Studio or SQL Server Database Tools. Active Directory integrated authentication Use this method if you are logged in to Windows using your Azure Active Directory credentials from a federated domain. 1. Start Management Studio or Data Tools and in the Connect to Server (or Connect to Database Engine) dialog box, in the Authentication box, select Active Directory - Integrated. No password is needed or can be entered because your existing credentials will be presented for the connection. 

2. Select the Options button, and on the Connection Properties page, in the Connect to database box, type the name of the user database you want to connect to. (The AD domain name or tenant ID option is only supported for Universal with MFA connection options, otherwise it is greyed out.)
