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?

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

Mule applications that implement a number of REST APIs are deployed to their own subnet that is inaccessible from outside the organization. External business-partners need to access these APIs, which are only allowed to be invoked from a separate subnet dedicated to partners - called Partner-subnet. This subnet is accessible from the public internet, which allows these external partners to reach it. Anypoint Platform and Mule runtimes are already deployed in Partner-subnet. These Mule runtimes can already access the APIs. What is the most resource-efficient solution to comply with these requirements, while having the least impact on other applications that are currently using the APIs?

A : Implement (or generate) an API proxy Mule application for each of the APIs, then deploy the API proxies to the Mule runtimes

B : Redeploy the API implementations to the same servers running the Mule runtimes

C : Add an additional endpoint to each API for partner-enablement consumption

D : Duplicate the APIs as Mule applications, then deploy them to the Mule runtimes

Answer: A

Question 3

Say, there is a legacy CRM system called CRM-Z which is offering below functions: 1. Customer creation 2. Amend details of an existing customer 3. Retrieve details of a customer 4. Suspend a customer

A : Implement a system API named customerManagement which has all the functionalities wrapped in it as various operations/resources

B : Implement different system APIs named createCustomer, amendCustomer, retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns

C : Implement different system APIs named createCustomerInCRMZ, amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as they are modular and has seperation of concerns

Answer: B

Question 4

The implementation of a Process API must change. What is a valid approach that minimizes the impact of this change on API clients?

A : Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition

B : Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version

C : Implement required changes to the Process API implementation so that whenever possible, the Process API-s RAML definition remains unchanged

D : Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation

Answer: C

Question 5

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
