Question 2

An API implementation is being designed that must invoke an Order API, which is known to repeatedly experience downtime. For this reason, a fallback API is to be called when the Order API is unavailable. What approach to designing the invocation of the fallback API provides the best resilience?

Options :

A :

Search Anypoint Exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the Order API

B :

Create a separate entry for the Order API in API Manager, and then invoke this API as a fallback API if the primary Order API is unavailable

C :

Redirect client requests through an HTTP 307 Temporary Redirect status code to the fallback API whenever the Order API is unavailable

D :

Set an option in the HTTP Requester component that invokes the Order API to instead invoke a fallback API whenever an HTTP 4xx or 5xx response status code is returned from the Order API

Answer: A

Question 3

The implementation of a Process API must change. What is a valid approach that minimizes the impact of this change on API clients?

Options :

A :

Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition

B :

Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version

C :

Implement required changes to the Process API implementation so that whenever possible, the Process API-s RAML definition remains unchanged

D :

Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation

Answer: C

Question 4

An API has been updated in Anypoint exchange by its API producer from version 3.1.1 to 3.2.0 following accepted semantic versioning practices and the changes have been communicated via the APIs public portal. The API endpoint does NOT change in the new version. How should the developer of an API client respond to this change?

Options :

A : The API producer should be requested to run the old version in parallel with the new one

B : The API producer should be contacted to understand the change to existing functionality

C : The API client code only needs to be changed if it needs to take advantage of the new features

D : The API clients need to update the code on their side and need to do full regression

Answer: C

Question 5
