CompTIA Network+ (N10-009) — Question 167

An administrator is evaluating the use of authentication within SNMP. Which of the following is the most secure way of authenticating devices using only SNMP?

Answer options

• A. Use version 1 of SNMP and use a community string to serve as a PSK
• B. Use version 3 of SNMP and set up trap messages for critical events on the network
• C. Use version 2c of SNMP and use informs to validate device authentication
• D. Use version 2u of SNMP to authenticate devices for network monitoring

Correct answer: B

Explanation

SNMP version 3 provides enhanced security features, including authentication and encryption, making it the most secure option for authenticating devices. The other options, such as using community strings in SNMP version 1 and 2c, lack the necessary security measures and are more susceptible to unauthorized access.
