NEW QUESTION 18
Refer to the exhibit.
What is the best way to decompose one end-to-end business process into a collaboration of Experience, Process, and of System APIs?
- A. Always use a tiered approach by creating exactly one API for each of the 3 layers (Experience, Process and System APIs).

NEW QUESTION 19
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. Duplicate the APIs as Mule applications, then deploy them to the Mule runtimes
- B. Implement (or generate) an API proxy Mule application for each of the APIs, then deploy the API proxies to the Mule runtimes
- C. Add an additional endpoint to each API for partner-enablement consumption
- D. Redeploy the API implementations to the same servers running the Mule runtimes
Answer: D
NEW QUESTION 20
In an organization, the InfoSec team is investigating Anypoint Platform related data traffic.
- A. From the Mule runtime irrespective of the deployment model
- B. From the Mule runtime or the API implementation, depending on the deployment model
- C. From the Mule runtime or the API Manager, depending on the type of data
- D. From where does most of the data available to Anypoint Platform for monitoring and alerting originate?
- E. From various components of Anypoint Platform, such as the Shared Load Balancer, VPC, and Mule runtimes
Answer: B
