A Layer 2 switch configuration places all its physical ports into VLAN 2. The IP Addressing plan shows that address 172.16.2.250 (with mask 255.255.255.0) is reserved for use by this new LAN switch and that 172.16.2.254 is already configured on the router connected to that same VLAN. The switch needs to support SSH connections into the switch from any subnet in the network. Which of the following commands are part of the required configuration in this case? A. The ip address 172.16.2.250 255.255.255.0 command in interface vlan 1 configuration mode. B. The ip address 172.16.2.250 255.255.255.0 command in interface vlan 2 configuration mode. C.

The switch cannot support SSH because all its ports connect to VLAN 2, and the IP address must be configured on interface VLAN 1.
