CompTIA Cloud+ (CV0-004) — Question 93

A company just learned that the data in its object storage was accessed by an unauthorized party. Which of the following should the company have done to make the data unusable?

Answer options

• A. The company should have switched from object storage to file storage.
• B. The company should have hashed the data.
• C. The company should have changed the file access permissions.
• D. The company should have encrypted the data at rest.

Correct answer: D

Explanation

Encrypting the data at rest ensures that even if unauthorized parties gain access, they cannot read or use the data without the decryption keys. Switching to file storage or changing access permissions do not make the data itself unusable, and hashing the data only provides integrity verification, not confidentiality.
