MuleSoft Certified Platform Architect – Level 1 — Question 56

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

Answer options

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• C. When the API implementation is migrated from an older to a newer version of the Mule runtime.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

Correct answer: A

Explanation

The correct answer is A because changes in the structure of request or response messages directly affect how the API is defined in RAML. Options B, C, and D pertain to other aspects of implementation that do not require changes to the RAML definition itself.
