Online application systems that detect an invalid transaction should do which of the following?
A.
Roll back and rewrite over original data.
B.
Terminate all transactions until properly addressed.
C.
Write a report to be reviewed.
D.
Checkpoint each data entry.
Explanation:
C: This can seem like a tricky question. It is asking you if the system detected an invalid transaction, which is most likely a user error. This error should be logged so it can be reviewed. After the review, the supervisor, or whoever makes this type of decision, will decide whether or not it was a mistake and investigate it as needed. If the system had a glitch, power fluctuation, hang-up, or any other software- or hardware-related error, it would not be an invalid transaction, and in that case the system would carry out a rollback function.
