Question #1

An API implementation is updated. When must the RAML definition of the API also be updated?

B. When the API implementation changes the structure of the request or response messages

C. When the API implementation is optimized to improve its average response time

D. When the API implementation is migrated from an older to a newer version of the Mule runtime

Question #2

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

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

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

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

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

Question #3

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?

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

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

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

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

Question #4

Version 3.0.1 of a REST API implementation represents time values in PST time using ISO 8601 hh:mm:ss format. The API implementation needs to be changed to instead represent time values in CEST time using ISO
8601 hh:mm:ss format. When following the semver.org semantic versioning specification, what version should be assigned to the updated API implementation?

A. 4.0.0

B. 3.0.1

C. 3.1.0

D. 3.0.2

A. API Consumer implementes logic to call an API >> API Client requests access to API >> API Implementation routes the request to >> API

B. API Consumer requests access to API >> API Client implementes logic to call an API >> API routes the request to >> API Implementation

C. API Client implementes logic to call an API >> API Consumer requests access to API >> API Implementation routes the request to >> API

D. API Client implementes logic to call an API >> API Consumer requests access to API >> API routes the request to >> API Implementation

Question #6

True or False. We should always make sure that the APIs being designed and developed are self-servable even if it needs more man-day effort and resources.

A. TRUE

B. FALSE

Question #7

An organization has created an API-led architecture that uses various API layers to integrate mobile clients with a backend system. The backend system consists of a number of specialized components and can be accessed via a REST API. The process and experience APIs share the same bounded-context model that is different from the backend data model. What additional canonical models, bounded-context models, or anti-corruption layers are best added to this architecture to help process data consumed from the backend system?

A. Create a bounded-context model for every layer and overlap them when the boundary contexts overlap, letting API developers know about the differences between upstream and downstream data models

B. Create a canonical model that combines the backend and API-led models to simplify and unify data models, and minimize data transformations.

C. Create an anti-corruption layer for every API to perform transformation for every data model to match each other, and let data simply travel between APIs to avoid the complexity and overhead of building canonical models

D. Create a bounded-context model for the system layer to closely match the backend data model, and add an anti-corruption layer to let the different bounded contexts cooperate across the system and process layers

Question #8

A system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. A process API is a client to the system API and is being rate limited by the system API, with different limits in each of the environments. The system API's DR environment provides only 20% of the rate limiting offered by the primary environment. What is the best API fault-tolerant invocation strategy to reduce overall errors in the process API, given these conditions and constraints?

A. Invoke the system API deployed to the primary environment; add timeout and retry logic to the process API to avoid intermittent failures; if it still fails, invoke the system API deployed to the DR environment

B. In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment; add timeout and retry logic to the process API to avoid intermittent failures; add logic to the process API to combine the results

C. Invoke the system API deployed to the primary environment; add timeout and retry logic to the process API to avoid intermittent failures; if it still fails, invoke a copy of the process API deployed to the DR environment

D. Invoke the system API deployed to the primary environment; add retry logic to the process API to handle intermittent failures by invoking the system API deployed to the DR environment

Question #9

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. 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

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

C. 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

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