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.

Answer : A

Answer : A

Correct Answer : When the API implementation changes the structure of the request or response messages

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

>> RAML definition usually needs to be touched only when there are changes in the request/response schemas or in any traits on API.

>> It need not be modified for any internal changes in API implementation like performance tuning, backend system migrations etc..

Answer : B

Correct Answer : The test runs immediately after the Mule application has been compiled and packaged

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

>> Integration tests are the last layer of tests we need to add to be fully covered.

>> These tests actually run against Mule running with your full configuration in place and are tested from external source as they work in PROD.

>> These tests exercise the application as a whole with actual transports enabled. So, external systems are affected when these tests run.

So, these tests do NOT run immediately after the Mule application has been compiled and packaged.

FYI... Unit Tests are the one that run immediately after the Mule application has been compiled and packaged.

Answer : D

Correct Answer :Workers are randomly distributed across available AZs within that region.

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

>>Currently, we only have control to choose which AWS Region to choose but there is no control at all using any configurations or deployment options to decide what Availability Zone (AZ) to assign to what worker.

>>There areNOfixed or implicit rules on platform too w.r.t assignment of AZ to workers based on environment or application.

>>They are completely assigned inrandom. However, cloudhub definitely ensures that HA is achieved by assigning the workers to more than on AZ so that all workers are not assigned to same AZ for same application.
