A. Source code comparison
B. Executable code comparison
C. Integrated test facilities (ITF)
D. Review of transaction log files
Answer / guest
Answer: D
Changes made to the payroll database table would appear in
the transaction log files. Because the original program was
restored, source and executable code comparisons are
ineffective. ITF is less effective than source code
comparison, because it is difficult to know what to look for.
