NEW QUESTION 18
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. Redirect client requests through an HTTP 307 Temporary Redirect status code to the fallback API whenever the Order API is unavailable
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. 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: D

NEW QUESTION 19
A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity.
The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms.
If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

A. Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete
B. Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries
C. Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds
D. No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API

Answer: A

NEW QUESTION 20
What API policy would LEAST likely be applied to a Process API?

B. Custom circuit breaker
C. Rate limiting

NEW QUESTION 22
An API implementation is deployed to CloudHub.

A. When a particular API client invokes the API too often within a given time period
B. When the API is invoked by an unrecognized API client
C. When the API receives a very high number of API invocations
D. When the response time of API invocations exceeds a threshold

Answer: A

NEW QUESTION 23
What Mule application deployment scenario requires using Anypoint Platform Private Cloud Edition or Anypoint Platform for Pivotal Cloud Foundry?

D. When ALL backend systems in the application network are deployed in the organization's intranet

Answer: A

NEW QUESTION 24
When designing an upstream API and its implementation, the development team has been advised to NOT set timeouts when invoking a downstream API, because that downstream API has no SLA that can be relied upon.
This is the only downstream API dependency of that upstream API.
Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?

A. A toad-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes
B. A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes
C. The invocation of the downstream API will run to completion without timing out
D. An SLA for the upstream API CANNOT be provided
