C : The number of new APIs that have been designed but not yet implemented

D : The quantity of internal training sessions held on API-led connectivity post-engagement

Answer: B

Question 4

An enterprise architect is reviewing a proposed solution architecture that includes several APIs. The architect is looking to ensure that the design principles support the company’s goal of creating reusable and easily modifiable components. What characteristic should the architect look for to determine if the solution adheres to the principles of composability?

Options :

A : APIs with a broad scope that can handle various business processes to reduce the total number of APIs

B : APIs that have a granular, focused responsibility and leverage common shared services for cross-cutting concerns
