Q6 Single choice

Your company provides a recommendation engine for retail customers. You are providing retail customers with an API where they can submit a user ID and the API returns a list of recommendations for that user.
You are responsible for the API lifecycle and want to ensure stability for your customers in case the API
makes backward-incompatible changes.

You want to follow Google-recommended practices.

What should you do?

A
Create a distribution list of all customers to inform them of an upcoming backward-incompatible change at least one month before replacing the old API with the new API.
B
Create an automated process to generate API documentation, and update the public API documentation as part of the CI/CD process when deploying an update to the API.
C
Use a versioning strategy for the APIs that increases the version number on every backward-incompatible change.
D
Use a versioning strategy for the APIs that adds the suffix "DEPRECATED" to the current API version number on every backward-incompatible change. Use the current version number for the new API.
