[All Salesforce Certified MuleSoft Platform Architect (Mule-Arch-201) Questions]

An API client calls one method from an existing API implementation. The API implementation is later updated. What change to the API implementation would require the API client's invocation logic to also be updated?

AWhen the data type of the response is changed for the method called by the API client

BWhen a new method is added to the resource used by the API client

CWhen a new required field is added to the method called by the API client

DWhen a child method is added to the method called by the API client

Show Suggested Answer

Suggested Answer: C

Correct Answer : When a new required field is added to the method called by the API client

*****************************************

>> Generally, the logic on API clients need to be updated when the API contract breaks.

>> When a new method or a child method is added to an API , the API client does not break as it can still continue to use its existing method. So these two options are out.

>> We are left for two more where 'datatype of the response if changed' and 'a new required field is added'.

>> Changing the datatype of the response does break the API contract. However, the question is insisting on the 'invocation' logic and not about the response handling logic. The API client can still invoke the API successfully and receive the response but the response will have a different datatype for some field.

>> Adding a new required field will break the API's invocation contract. When adding a new required field, the API contract breaks the RAML or API spec agreement that the API client/API consumer and API provider has between them. So this requires the API client invocation logic to also be updated.

Hmm, I'm a bit confused by the wording of the question. I'll need to re-read it carefully to make sure I understand the key concepts.

Okay, I think I've got it. Volt/Var control and optimization is all about regulating voltage and reactive power to keep the system stable and within acceptable limits. That's what option B is describing.

Hmm, I'm a bit unsure about this one. The options seem to cover different IT roles, but I'm not sure which one would have the most relevant operational knowledge for this project. I'll need to carefully consider the responsibilities of each role.

I'm a little confused by the different code fragments. I need to make sure I understand how the "import" element works and how it relates to the schema location. I'll review the question again and try to reason through the options step-by-step.

Haha, oh boy. This is like a game of API roulette. I'm just going to go with C and hope I don't get fired for it.

Option D is the way to go, clearly. Adding a child method is the most logical choice here. What could possibly go wrong?

Hmm, this is a tricky one. I'm torn between B and C, but I think C is the safest bet. Who knows what kind of weird API implementations are out there?

Yeah, it's better to be safe and update the invocation logic just in case.

I agree, adding a new required field to the method called by the API client would definitely require an update.

I agree with Annelle. Adding a required field is the only change that would force the client to update their invocation logic. The other options are just enhancements that the client can ignore.

So, it's important for the client to stay updated with any required field changes in the API implementation.

I think the answer is B) When a new method is added to the resource used by the API client. That would definitely require updating the API client's invocation logic.

Option C is definitely the correct answer. Changing the data type or adding a new method wouldn't require the client to update their code, but adding a new required field would break the contract.

Exactly, adding a new required field changes the contract between the API client and the implementation.

Yes, that's right. Changing the data type or adding a new method wouldn't necessarily break the client's code.
