The network administrator wants to place contractor clients and employee clients in different broadcast domains.

How should the administrator achieve this goal?

A. Add a router in between Switch 1 and Switch 2. Configure a different subnet on each router interface.
B. Create two MSTP instances on each switch. Assign ports connected to contractor clients to one instance and ports connected to employee clients to the other instance.

C. Assign the switch ports connected to contractor clients to one VLAN and ports connected to employee clients to another VLAN. Extend the VLANs between the switches.

D. Create two device profiles. Apply one profile to ports connected to contractor clients, and apply the other profile to ports connected to employee clients.
