Microsoft Azure Architect Design (AZ-304) Practice Test

Which solution can provide external developers with access to Azure Logic Apps using their existing OAuth 2.0 authentication?

1. Azure API Management

2. Azure Active Directory B2B

3. Azure Logic Apps with custom connectors

4. Azure Event Hubs

The correct answer is: Azure Logic Apps with custom connectors

The solution that effectively provides external developers with access to Azure Logic Apps using their existing OAuth 2.0 authentication is custom connectors within Azure Logic Apps. Custom connectors allow you to extend the capabilities of Logic Apps by enabling integration with external services that use OAuth 2.0 for authentication. By utilizing custom connectors, developers can create tailored connections to different APIs, which include the necessary OAuth 2.0 authentication flow. This is particularly useful for external developers as it allows them to authenticate using their existing credentials, enabling seamless integration without the need for them to manage additional credentials or custom authentication methods. Other options, such as Azure API Management, while capable of managing APIs and providing access control, do not inherently build the OAuth 2.0 connection required for Logic Apps. Azure Active Directory B2B focuses on secure collaboration between organizations but does not directly facilitate API access to Logic Apps for external developers. Azure Event Hubs primarily acts as an event ingestion service for big data applications and does not pertain to the authentication features related to Logic Apps. Thus, utilizing custom connectors in conjunction with Logic Apps effectively meets the requirement of providing external developers access while supporting their existing OAuth 2.0 authentication framework.
