Google Professional Cloud Architect (PR000213) Exam - Topic 2 Question 9 Discussion

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?
C) Use a versioning strategy for the APIs that increases the version number on every backward-incompatible change.
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.
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.

Suggested Answer: C

https://cloud.google.com/apis/design/versioning

All Google API interfaces must provide a major version number, which is encoded at the end of the protobuf package, and included as the first part of the URI path for REST APIs. If an API introduces a breaking change, such as removing or renaming a field, it must increment its API version number to ensure that existing user code does not suddenly break.

I think D is a bit confusing, why add "DEPRECATED"?

I practiced a similar question where we had to ensure API stability. I think option B is crucial for keeping documentation up to date, but I wonder if it addresses backward compatibility directly.

I feel like option D could be a good choice too, especially since it highlights deprecated versions. But does adding "DEPRECATED" really help customers?

I remember discussing the importance of versioning in our last class. I think option C makes sense, but I'm not entirely sure if it's the best approach.

I’m leaning towards option C for versioning, but I recall some debate about how often we should increment version numbers. It might be more complex than it seems.

Okay, let's see here. The question is asking what happens when the audit indicates two items with a warning. I think the key is figuring out how that affects the deployment of the email.

Okay, let me double-check. We have "to=el" and "toScript=Latn" covered. But do we also need "from=el" to specify the source language? I'm not 100% sure about that one.
