Which command implies the use of SNMPv3?

snmp-server user. SNMPv3 introduces user-based security, authentication, and optional encryption. The command snmp-server user is therefore the command that implies SNMPv3 because users are created for SNMPv3 security models. The snmp-server community command is associated with SNMPv1 and SNMPv2c community strings, which are weaker and do not provide the same authentication and privacy capabilities. The snmp-server host and snmp-server enable traps commands can be used in broader SNMP configurations, but they do not by themselves identify SNMPv3. Cisco CCNA 200-301 v1.1 IP Services expects engineers to know that SNMPv3 is the secure version preferred for device monitoring. The original community-string answer was wrong and has been corrected to snmp-server user.
