Question 47

A new Mule application under development must implement extensive data transformation logic. Some of the data transformation functionality is already available as external transformation services that are mature and widely used across the organization; the rest is highly specific to the new Mule application.

The organization follows a rigorous testing approach, where every service and application must be extensively acceptance tested before it is allowed to go into production.

What is the best way to implement the data transformation logic for this new Mule application while minimizing the overall testing effort?

Implement transformation logic in the new Mule application using DataWeave, replicating the transformation logic of existing transformation services

Implement transformation logic in the new Mule application using DataWeave, invoking existing transformation services when possible

Extend the existing transformation services with new transformation logic and invoke them from the new Mule application

Implement and expose all transformation logic as microservices using DataWeave, so it can be reused by any application component that needs it, including the new Mule application

Correct Answer: B

The best approach to minimize overall testing effort is to implement the new and highly specific transformation logic directly within the new Mule application using DataWeave and invoke the existing mature and widely used transformation services when possible. This approach leverages the already tested and reliable existing transformation services, reducing the need for extensive testing of these parts, while avoiding redundant implementations.

Discussion

majda091983Option: B

B is the best answer

Outdoor25Option: B

Should be B, as it uses existing transformation service when possible reducing testing effort. Any other answer involves new implementation of transformation logic which will cause extensive testing.

AlandtOption: B

B according to ChatGPT

vikas_muleOption: C

C is correct as services are already their so new application need to invoke them to minimize resting effort

madgeezerOption: B

B. Implement transformation logic in the new Mule application using DataWeave, invoking existing transformation services when possible Clue is that the new logic is highly specific to the new Mule application

Ricky9Option: A

A is the correct Answer
