PLC-3 and CLIENT can send traffic to PLC-1 and PLC-2. FGT-2 has only one software switch (SSW-1) connecting both PLC-3 and CLIENT. PLC-3 and CLIENT can send traffic to each other at the Layer 2 level.
What must the OT admin do to prevent Layer 2-level communication between PLC-3 and CLIENT?

With the limit of using one firewall device, the administrator enables multi-VDOM on FortiGate to provide independent multiple security domains to each ICS network. Which statement ensures security protection is in place for all ICS networks?

Refer to the exhibit.

You need to configure VPN user access for supervisors at the breach and HQ sites using the same soft FortiToken. Each site has a FortiGate VPN gateway.
What must you do to achieve this objective?

As an OT network administrator, you are managing three FortiGate devices that each protect different levels on the Purdue model. To increase traffic visibility, you are required to implement additional security measures to detect exploits that affect PLCs. Which security sensor must implement to detect these types of industrial exploits?

In a wireless network integration, how does FortiNAC obtain connecting MAC address information?
