Question :-

During acceptance testing of an integration solution, various errors in the mediation flows were discovered. While correcting these errors, the development team found that little or no error handling was present within the mediation flows. Therefore, a new requirement is introduced to handle every exception within any mediation flow in exactly the same way by logging the exception to a file. How can an integration developer implement this requirement?
Connect a trace primitive to each fail terminal.
Create a mediation flow containing the exception handling logic, and invoke it whenever an error occurs.
Create a mediation subflow containing the exception handling logic, and connect every fail terminal to this new subflow.
Create a mediation subflow containing the exception handling logic, and connect the error input node of each mediation flow to this new subflow.
