Security in Amazon Web Services (CISN 74A) Practice Test

The correct answer highlights AWS's commitment to data integrity through the maintenance of comprehensive data logs and version histories. This approach allows AWS to track and verify changes made to data, ensuring that any unauthorized modifications or corruption can be detected and addressed promptly. The ability to refer back to previous versions of data also enables recovery from accidental deletions or unintended changes, which is fundamental in maintaining the overall integrity of the data stored in the cloud.

Maintaining comprehensive logs can also aid in compliance with regulatory requirements and support auditing activities. This level of oversight contributes to the transparency and trustworthiness of the data management practices in AWS.

Other options do not address data integrity as effectively. Manual audits can be helpful but are not a scalable or efficient method for ongoing data integrity checks. Relying solely on customer certificates does not inherently provide safeguards for the integrity of data itself, as certificates are primarily focused on authentication and encryption. Backing up data every six months is too infrequent to ensure data integrity, as it does not allow for immediate recovery or validation of data changes that may occur in-between backup sessions.
