A. A customer-hosted load balancer
B. Runtime Manager autoscaling
C. An API proxy
D. The CloudHub shared load balancer

B. The API policy Is defined In API Manager for a specific API Instance, and then ONLY applied to the specific API instance
C. The API policy Is defined in API Manager and then automatically applied to ALL API instances
D. The API policy Is defined In Runtime Manager as part of the API deployment to a Mule runtime, and then ONLY applied to the specific API Instance

B. When the data type of the response is changed for the method called by the API client
C. When a new required field is added to the method called by the API client

質問 6：
Refer to the exhibit.

Three business processes need to be implemented, and the implementations need to communicate with several different SaaS applications.
These processes are owned by separate (siloed) LOBs and are mainly independent of each other, but do share a few business entities. Each LOB has one development team and their own budget In this organizational context, what is the most effective approach to choose the API data models for the APIs that will implement these business processes with minimal redundancy of the data models?
A) Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities

B) Build distinct data models for each API to follow established micro-services and Agile API-centric practices

C) Build all API data models using XML schema to drive consistency and reuse across the organization

D) Build one centralized Canonical Data Model (Enterprise Data Model) that unifies all the data types from all three business processes, ensuring the data model is consistent and non-redundant

A. Option A
B. Option C
C. Option D
D. Option B

質問 7：
What is most likely NOT a characteristic of an integration test for a REST API implementation?
A. The test needs all source and/or target systems configured and accessible
B. The test runs immediately after the Mule application has been compiled and packaged
C. The test is triggered by an external HTTP request
D. The test prepares a known request payload and validates the response payload
正解：B
