1Refer to the exhibit. The Fa0/2 interface on switch S1 has been configured with the switchport port-security mac-address 0023.189d.6456 command and a workstation has been connected. What could be the reason that the Fa0/2 interface is shutdown?

- AThe connection between S1 and PC1 is via a crossover cable
- BThe Fa0/24 interface of S1 is configured with the same MAC address as the Fa0/2 interface
- CS1 has been configured with a switchport port-security aging command
- DThe MAC address of PC1 that connects to the Fa0/2 interface is not the configured MAC address
