Question 9

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 API's 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 update should be identified as a project risk and full regression testing of the functionality that uses this API should be run

B.

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

C.

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

D.

The API client code ONLY needs to be changed if it needs to take advantage of new features

Question 10

What is a key performance indicator (KPI) that measures the success of a typical C4E that is immediately apparent in responses from the Anypoint Platform APIs?

Options:

A.

The number of production outage incidents reported in the last 24 hours

B.

The number of API implementations that have a publicly accessible HTTP endpoint and are being managed by Anypoint Platform

C.

The fraction of API implementations deployed manually relative to those deployed using a CI/CD tool

D.

The number of API specifications in RAML or OAS format published to Anypoint Exchange

Question 11

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

Question 12

What is a typical result of using a fine-grained rather than a coarse-grained API deployment model to implement a given business process?

Options:

A.

A decrease in the number of connections within the application network supporting the business process

B.

A higher number of discoverable API-related assets in the application network

C.

A better response time for the end user as a result of the APIs being smaller in scope and complexity

D.

An overall tower usage of resources because each fine-grained API consumes less resources
