Certified Information Systems Auditor (CISA) — Question 1378
When testing the adequacy of tape backup procedures, which step BEST verifies that regularly scheduled backups are timely and run to completion?
Answer options
- A. Reviewing a sample of system-generated backup logs
- B. Interviewing key personnel involved in the backup process
- C. Observing the execution of a daily backup run
- D. Evaluating the backup policies and procedures
Correct answer: A
Explanation
The correct answer, A, involves checking system-generated backup logs, which provide concrete evidence of backup completion and timing. Options B and C, while helpful, rely on subjective inputs or observations that may not accurately reflect the entire backup process. Option D addresses policy evaluation but does not directly verify the actual execution of backups.
