HOTSPOT - You have an Azure subscription named Sub1 that is associated to an Azure Active Directory (Azure AD) tenant named contoso.com. You plan to implement an application that will consist of the resources shown in the following table. 

Users will authenticate by using their Azure AD user account and access the Cosmos DB account by using resource tokens. You need to identify which tasks will be implemented in CosmosDB1 and WebApp1. Which task should you identify for each resource? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Hot Area: 

CosmosDB1: Create database users and generate resource tokens. Azure Cosmos DB resource tokens provide a safe mechanism for allowing clients to read, write, and delete specific resources in an Azure Cosmos DB account according to the granted permissions. WebApp1: Authenticate Azure AD users and relay resource tokens A typical approach to requesting, generating, and delivering resource tokens to a mobile application is to use a resource token broker. The following diagram shows a high-level overview of how the sample application uses a resource token broker to manage access to the document database data:
