Question 3

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?

Options :

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 4

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

Options :

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
