Question 1

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

Answer: A

Question 2

A large organization with an experienced central IT department is getting started using MuleSoft. There is aproject to connect a siloed back-end system to a newCustomer Relationship Management (CRM) system. The Center for Enablement is coaching them to use APIled connectivity.What action would support the creation of an application network using API-led connectivity?

Options :

A : Invite the business analyst to create a business process model to specify the canonical data model between the two systems

B : Determine if the new CRM system supports the creation of custom: REST APIs, establishes 4 private network with CloudHub, and supports GAuth 2.0 authentication

C : To expedite this project, central IT should extend the CRM system and back-end systems to connect to one another using built in integration interfaces

D : Create a System API to unlock the data on the back-end system using a REST API

Answer: D

Question 3

When can CloudHub Object Store v2 be used?

Options :

A : To store an unlimited number of key-value pairs

B : To store payloads with an average size greater than 15MB

C : To store information in Mule 4 Object Store v1

D : To store key-value pairs with keys up to 300 characters

Answer: D

Question 4

In which layer of API-led connectivity, does the business logic orchestration reside?

Options :

A : System Layer

B : Experience Layer

C : Process Layer

Answer: C

Question 5

An Order API must be designed that contains significant amounts of integration logic and involves the invocation of the Product API. The power relationship between Order API and Product API is one of "Customer/Supplier", because the Product API is used heavily throughout the organization and is developed by a dedicated development team located in the office of the CTO. What strategy should be used to deal with the API data model of the Product API within the Order API?

Options :

A : Convince the development team of the Product API to adopt the API data model of the Order API such that the integration logic of the Order API can work with one consistent internal data model

B : Work with the API data types of the Product API directly when implementing the integration logic of the Order API such that the Order API uses the same (unchanged) data types as the Product API

C : Implement an anti-corruption layer in the Order API that transforms the Product API data model into internal data types of the Order API

D : Start an organization-wide data modeling initiative that will result in an Enterprise Data Model that will then be used in both the Product API and the Order API
