CompTIA Cloud+ (CV1-003) — Question 62

A systems administrator needs to configure an email client to ensure data integrity of the email messages.
Which of the following provides the BEST mechanism to achieve this goal?

Answer options

• A. Cyclic redundancy check
• B. SHA-1 hashes
• C. SHA-256 hashes
• D. Digital signature

Correct answer: A

Explanation

The best method for ensuring data integrity in email messages is the Cyclic Redundancy Check (CRC), as it detects accidental changes to raw data. While SHA-1 and SHA-256 hashes are used for cryptographic purposes, they don't specifically provide an integrity check in the context of email clients. Digital signatures, while useful for authenticity and integrity, are not primarily focused on data integrity alone.
