CompTIA Network+ (N10-008) — Question 591

A network engineer needs to enable device monitoring using authentication and encryption. Which of the following protocols offers this option?

Answer options

• A. ESP
• B. SNMPv3
• C. NetFlow
• D. SSLv3

Correct answer: B

Explanation

SNMPv3 is the correct choice because it provides both authentication and encryption for secure network management. ESP, while it offers encryption, is primarily used for securing IP traffic rather than device monitoring. NetFlow is a network protocol for collecting IP traffic information but does not provide authentication or encryption. SSLv3 is a protocol for securing communications over a network but is not specifically designed for device monitoring.
