Question #138

Your company, named Contoso, Ltd, implements several Azure logic apps that have HTTP triggers. The logic apps provide access to an on-premises web service.
Contoso establishes a partnership with another company named Fabrikam, Inc.
Fabrikam does not have an existing Azure Active Directory (Azure AD) tenant and uses third-party OAuth 2.0 identity management to authenticate its users.
Developers at Fabrikam plan to use a subset of the logic apps to build applications that will integrate with the on-premises web service of Contoso.
You need to design a solution to provide the Fabrikam developers with access to the logic apps. The solution must meet the following requirements:
✑ Requests to the logic apps from the developers must be limited to lower rates than the requests from the users at Contoso.
✑ The developers must be able to rely on their existing OAuth 2.0 provider to gain access to the logic apps.
✑ The solution must NOT require changes to the logic apps.
✑ The solution must NOT use Azure AD guest accounts.
What should you include in the solution?

A. Azure AD business-to-business (B2B)
B. Azure Front Door
C. Azure API Management
D. Azure AD Application Proxy

Correct Answer: C
API Management helps organizations publish APIs to external, partner, and internal developers to unlock the potential of their data and services.
You can secure API Management using the OAuth 2.0 client credentials flow.
Incorrect Answers:
A: Azure Active Directory B2B uses guest users.
B: Azure Front Door is an Application Delivery Network (ADN) as a service, offering various layer 7 load-balancing capabilities for your applications.
Azure Front Door supports HTTP, HTTPS and HTTP/2.
Applications can be authorized through OAuth 2.0.
D: Application Proxy is a feature of Azure AD that enables users to access on-premises web applications from a remote client. Application Proxy includes both the
Application Proxy service which runs in the cloud, and the Application Proxy connector which runs on an on-premises server.
Application Proxy works with:
✑ Web applications that use Integrated Windows Authentication for authentication
Web applications that use form-based or header-based access
