Which command should the network administrator implement to prevent the transfer of DTP frames between a Cisco switch and a non-Cisco switch?

S1(config-if)# switchport mode trunk
S1(config-if)# switchport nonegotiate
S1(config-if)# switchport mode dynamic desirable
S1(config-if)# switchport mode access
S1(config-if)# switchport trunk allowed vlan none

Explanation: To prevent DTP frames from being generated by the interface of a Cisco switch, use the S1(config-if)# switchport nonegotiate command. DTP is Cisco proprietary and not usable by other vendors.
