Question 82

A Mule application is synchronizing customer data between two different database systems.

What is the main benefit of using eXtended Architecture (XA) transactions over local transactions to synchronize these two different database systems?

An XA transaction synchronizes the database systems with the least amount of Mule configuration or coding

An XA transaction handles the largest number of requests in the shortest time

An XA transaction automatically rolls back operations against both database systems if any operation falls

An XA transaction writes to both database systems as fast as possible

Correct Answer: C

The main benefit of using eXtended Architecture (XA) transactions over local transactions to synchronize two different database systems is that an XA transaction automatically rolls back operations against both database systems if any operation fails. This ensures data integrity and consistency across both systems, as partial updates or inconsistencies will be avoided in the event of a failure.
