Question 420
At the Kingsford manufacturing group during a controlled pilot, a synchronous plug-in catches an exception and silently reports success after a required invariant was violated. The project team must verify a scoped fix before rollout. Which ongoing engineering control would most directly reduce recurrence?
Explanation
Correct Answer
Make future changes safer by ensuring teams test failure and rollback behavior for critical validations. The control belongs with the original correction to throw a suitable plug-in exception for business-critical invalid data to abort the operation. In the Kingsford manufacturing group, assess this against the documented transaction failure handling scenario.
Incorrect Answers
This monitoring or review practice targets update filtering attributes; the better ongoing protection for this case is to test failure and rollback behavior for critical validations. For case R082-PL400-CASE-0105, the decisive context is the 1 deployment setting at the Kingsford manufacturing group.
“Test version conflicts when changing write logic” checks a different ongoing risk rather than the reported failure: at the Kingsford manufacturing group during a controlled pilot, a synchronous plug-in catches an exception and silently reports success after a required invariant was violated. The project team must verify a scoped fix before rollout. The relevant mechanism is swallowing a validation failure allows inconsistent rows to persist. The directly matched preventive control is “Test failure and rollback behavior for critical validations”.
This monitoring or review practice targets asynchronous plug-in fit; the better ongoing protection for this case is to test failure and rollback behavior for critical validations. For case R082-PL400-CASE-0105, the decisive context is the 1 deployment setting at the Kingsford manufacturing group.
