A company has created a successful enterprise data model (EDM). The company is committed to building an application network by adopting modern APIs as a core enabler of the company's IT operating model. At what API tiers (experience, process, system) should the company require reusing the EDM when designing modern API data models?

A. At the process and system tiers

B. At the experience and process tiers

C. At the experience, process, and system tiers

D. At the experience and system tiers

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 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

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

出題：5

What is most likely NOT a characteristic of an integration test for a REST API implementation?

A. The test runs immediately after the Mule application has been compiled and packaged

B. The test needs all source and/or target systems configured and accessible

C. The test prepares a known request payload and validates the response payload

D. The test is triggered by an external HTTP request

A retail company is using an Order API to accept new orders. The Order API uses a JMS queue to submit orders to a backend order management service. The normal load for orders is being handled using two (2) CloudHub workers, each configured with 0.2 vCore. The CPU load of each CloudHub worker normally runs well below 70%. However, several times during the year the Order API gets four times (4x) the average number of orders. This causes the CloudHub worker CPU load to exceed 90% and the order submission time to exceed 30 seconds. The cause, however, is NOT the backend order management service, which still responds fast enough to meet the response SLA for the Order API. What is the MOST resource-efficient way to configure the Mule application's CloudHub deployment to help the company cope with this performance challenge?

A. Use a vertical CloudHub autoscaling policy that triggers on CPU utilization greater than 70%

B. Use a horizontal CloudHub autoscaling policy that triggers on CPU utilization greater than 70%

C. Permanently increase the number of CloudHub workers by four times (4x) to eight (8) CloudHub workers

D. Permanently increase the size of each of the two (2) CloudHub workers by at least four times (4x) to one (1) vCore

出題：7

When could the API data model of a System API reasonably mimic the data model exposed by the corresponding backend system, with minimal improvements over the backend system's data model?

A. When there is an existing Enterprise Data Model widely used across the organization

B. When a pragmatic approach with only limited isolation from the backend system is deemed appropriate

C. When the corresponding backend system is expected to be replaced in the near future

D. When the System API can be assigned to a bounded context with a corresponding data model

出題：8

How are an API implementation, API client, and API consumer combined to invoke and process an API?

A. The API consumer creates an API implementation, which receives API invocations from an API such that they are processed for an API client

B. The ApI client creates an API consumer, which sends API invocations to an API such that they are processed by an API implementation

C. The ApI consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation

D. The API client creates an API consumer, which receives API invocations from an API such that they are processed for an API implementation
