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

An organization has implemented a Customer Address API to retrieve customer address information. This API has been deployed to multiple environments and has been configured to enforce client IDs everywhere.
A developer is writing a client application to allow a user to update their address. The developer has found the Customer Address API in Anypoint Exchange and wants to use it in their client application.
What step of gaining access to the API can be performed automatically by Anypoint Platform?

A. Modify the client application to call the API using the client application's credentials

B. Create a new application in Anypoint Exchange for requesting access to the API

C. Request access to the appropriate API Instances deployed to multiple environments using the client application's credentials

D. Approve the client application request for the chosen SLA tier

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.

An organization wants to make sure only known partners can invoke the organization's APIs. To achieve this security goal, the organization wants to enforce a Client ID Enforcement policy in API Manager so that only registered partner applications can invoke the organization's APIs. In what type of API implementation does MuleSoft recommend adding an API proxy to enforce the Client ID Enforcement policy, rather than embedding the policy directly in the application's JVM?

A. A Mule 3 application using APIkit

B. A Mule 3 or Mule 4 application modified with custom Java code

C. A Non-Mule application

D. A Mule 4 application with an API specification

What is a best practice when building System APIs?

A. Expose to API clients all technical details of the API implementation's interaction wifch the backend system

B. Document the API using an easily consumable asset like a RAML definition

C. Build an Enterprise Data Model (Canonical Data Model) for each backend system and apply it to System APIs

D. Model all API resources and methods to closely mimic the operations of the backend system
