MuleSoft Certified Developer – Level 1 — Question 39

In an application network, if the implementation but not the interface of a product API changes, what needs to be done to the other APIs that consume the product
API?

Answer options

• A. The applications associated with the other APIs must be restarted
• B. The other APIs must be updated to consume the updated product API
• C. Nothing needs to be changed in the other APIs or their associated applications
• D. The applications associated with the other APIs must be recoded

Correct answer: B

Explanation

The correct answer is B because changes in the implementation of the product API can affect how the other APIs interact with it, necessitating updates to ensure compatibility. Options A and D suggest unnecessary actions, as restarting or recoding applications is not required when only the implementation changes. Option C is incorrect because it overlooks the need for updates to maintain proper functionality.
