Which command would be best to use on an unused switch port if a company adheres to the best practices as recommended by Cisco?
- ip dhcp snooping
- switchport port-security mac-address sticky
- switchport port-security violation shutdown
- switchport port-security mac-address sticky mac-address
Explanation: Unlike router Ethernet ports, switch ports are enabled by default. Cisco recommends disabling any port that is not used. The ip dhcp snooping command globally enables DHCP snooping on a switch. Further configuration allows defining ports that can respond to DHCP requests. The switchport port-security command is used to protect the network from unidentified or unauthorized attachment of network devices.
