Q8 Single choice

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?

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
