What must the OT admin do to prevent Layer 2-level communication between PLC-3 and CLIENT?

Options:

Set a unique forward domain for each interface of the software switch.

Create a VLAN for each device and replace the current FGT-2 software switch members.

Enable explicit intra-switch policy to require firewall policies on FGT-2.

Implement policy routes on FGT-2 to control traffic between devices.
