CCIE Security (legacy) — Question 2

Which three security features were introduced with the SNMPv3 protocol? (Choose three.)

Answer options

• A. Message integrity, which ensures that a packet has not been tampered with in-transit
• B. DoS prevention, which ensures that the device cannot be impacted by SNMP buffer overflow
• C. Authentication, which ensures that the message is from a valid source
• D. Authorization, which allows access to certain data sections for certain authorized users
• E. Digital certificates, which ensure nonrepudiation of authentications
• F. Encryption of the packet to prevent it from being seen by an unauthorized source

Correct answer: A, C, F

Explanation

The correct answers are A, C, and F, as these features ensure the integrity, authenticity, and confidentiality of the SNMPv3 messages. Option B refers to a prevention mechanism that is not specifically a feature of SNMPv3, while D and E, although related to security, do not pertain to the core features introduced in SNMPv3.
