CompTIA Network+ (N10-009) — Question 371

Which of the following most directly secures sensitive information on a network?

Answer options

• A. Data-in-transit encryption
• B. Principle of least privilege
• C. Role-based access controls
• D. Multifactor authentication

Correct answer: A

Explanation

Data-in-transit encryption is designed to protect sensitive information as it moves across networks, making it the most direct method for securing such data. The other options, while important for overall security, either focus on access control (B and C) or user verification (D) rather than specifically encrypting data during transmission.
