Planned Changes and Requirements. Business Requirements Litware identifies the following business requirements: ✑ Minimize administrative effort. ✑ Minimize costs. You plan to migrate App1 to Azure. The solution must meet the authentication and authorization requirements. Which type of endpoint should App1 use to obtain an access token? A. Azure Instance Metadata Service (IMDS) B. Azure AD 4 / 46 C. Azure Service Management D. Microsoft identity platform Answer: D Explanation: Scenario: To access the resources in Azure, App1 must use the managed identity of the virtual machines that will host the app. Managed identities provide an identity for applications to use when connecting to resources that support Azure Active Directory (Azure AD) authentication. Applications may use the managed identity to obtain Azure AD tokens. Reference: https://docs.microsoft.com/en-us/azure/active-directory/managedidentities-azure-resources/overview 2.
