Certified Data Privacy Solutions Engineer (CDPSE) — Question 190

Which of the following is the BEST method to ensure the security of encryption keys when transferring data containing personal information between cloud applications?

Answer options

• A. Whole disk encryption
• B. Asymmetric encryption
• C. Digital signature
• D. Symmetric encryption

Correct answer: B

Explanation

Asymmetric encryption is the best method in this scenario because it uses a pair of keys (public and private) which allows for secure key exchange without exposing the keys during the data transfer. Whole disk encryption, digital signatures, and symmetric encryption do not provide the same level of secure key management during transit, making them less suitable for this specific requirement.
