Certified Information Systems Auditor (CISA) — Question 495

An organization sends daily backup media by courier to an offsite location. Which of the following provides the BEST evidence that the media is transported reliably?

Answer options

• A. Documented backup media transport procedures
• B. Signed acknowledgments by offsite manager
• C. Certification of the courier company
• D. Delivery schedule of the backup media

Correct answer: B

Explanation

Signed acknowledgments by the offsite manager serve as direct proof that the media has been received and verified at the destination, ensuring accountability. While documented procedures and courier certifications are important, they do not provide confirmation of actual delivery. A delivery schedule merely outlines when deliveries are supposed to occur, without confirming their successful completion.
