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?
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
B. Use version 3 of SNMP and set up trap messages for critical events on the network.
Explanation:
SNMP version 3 (SNMPv3) is the most secure version of SNMP as it supports both authentication and encryption. It allows for stronger security protocols, such as user-based authentication (using MD5 or SHA) and message encryption (using DES, AES, etc.), ensuring that SNMP communication is protected from eavesdropping and unauthorized access.
