An API implementation is updated. When must the RAML definition of the API also be updated?

• A. When the API implementation changes from interacting with a legacy backend system deployed on-premises to a modern, cloud-based (SaaS) system
• B. When the API implementation is optimized to improve its average response time
• C. When the API implementation changes the structure of the request or response messages
• D. When the API implementation is migrated from an older to a newer version of the Mule runtime

Refer to the exhibits.

Which architectural constraint is compatible with the API-led connectivity architectural style?

• A. Use a Process API to-orchestrate calls to multiple System APIs but not to other Process APIs:
• B. Allow System APIs to return data that is not currently required by the identified Process or Experience APIs
  
• C. Always use a tiered approach by creating exactly one API for each of the three layers (Experience, Process, and System)
  
• D. Handle customizations for the end-user application at the Process layer rather than at the Experience layer

An API implementation is being designed that must invoke an Order API, which is known to repeatedly experience downtime.
For this reason, a fallback API is to be called when the Order API is unavailable.
What approach to designing the invocation of the fallback API provides the best resilience?

• A. Create a separate entry for the Order API in API Manager, and then invoke this API as a fallback API if the primary Order API is unavailable
• B. Redirect client requests through an HTTP 307 Temporary Redirect status code to the fallback API whenever the Order API is unavailable
• C. Set an option in the HTTP Requester component that invokes the Order API to instead invoke a fallback API whenever an HTTP 4xx or 5xx response status code is returned from the Order API
• D. Search Anypoint Exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the Order API

What best explains the use of auto-discovery in API implementations?

• A. It enables Anypoint Analytics to gain insight into the usage of APIs
• B. It enables Anypoint Exchange to discover assets and makes them available for reuse
• C. It makes API Manager aware of API implementations and hence enables it to enforce policies
• D. It enables Anypoint Studio to discover API definitions configured in Anypoint Platform

A business process is being implemented within an organization's application network. The architecture group proposes using a more coarse-grained application network design with relatively fewer APIs deployed to the application network compared to a more fine-grained design.
Overall, which factor typically increases with a more coarse-grained design for this business process implementation and deployment compared with using a more fine-grained design?

• A. The usage of network infrastructure resources by the application network
• B. The complexity of each API implementation
• C. The number of possible connections between API implementations in the application network
• D. The number of discoverable assets related to APIs deployed in the application network
