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

Explanation: Explanation
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.

When the response time of API invocations exceeds a threshold

Explanation: Explanation
Correct Answer: When the response time of API invocations exceeds a threshold
*****************************************
>> Alerts can be setup for all the given options using the default Anypoint Platform
functionality
>> However, the question insists on an alert whose conditions depend on the end-to-end
request processing of the API implementation.
>> Alert w.r.t "Response Times" is the only one which requires end-to-end request
processing of API implementation in order to determine if the threshold is exceeded or not.

Option A

Explanation: Explanation
Correct Answer: Build several Bounded Context Data Models that align with coherent
parts of the business processes and the definitions of associated business entities.
*****************************************
>> The options w.r.t building API data models using XML schema/ Agile API-centric
practices are irrelevant to the scenario given in the question. So these two are INVALID.
>> Building EDM (Enterprise Data Model) is not feasible or right fit for this scenario as the
teams and LOBs work in silo and they all have different initiatives, budget etc.. Building
EDM needs intensive coordination among all the team which evidently seems not possible
in this scenario.
So, the right fit for this scenario is to build several Bounded Context Data Models that align
with coherent parts of the business processes and the definitions of associated business
