Certified Information Systems Auditor (CISA) — Question 796

Which of the following provides the BEST assurance of data integrity after file transfers?

Answer options

• A. Cheek digits
• B. Monetary unit sampling
• C. Reasonableness check
• D. Hash values

Correct answer: D

Explanation

Hash values are cryptographic representations of data that allow for verification of integrity by comparing the hash of the original file with the hash of the transferred file. The other options, while useful in certain contexts, do not specifically address data integrity assurance in file transfers as effectively as hash values do.
