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 AP
C . 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.
D . Redirect client requests through an HTTP 307 Temporary Redirectstatus code to the fallback API whenever the Order API is unavailable.
E . 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 AP
Answer: A
