To implement this scenario, what would be the best option available in the ESB profile?

ANone of these approaches would implement this scenario.

BUse the Switch mediator.

CWrite a custom Class mediator and implement the custom routing logic inside that mediator.

DUse the Script mediator and implement the above routing logic.

Answer : D

Question 3
