An OT architect has deployed a Layer 2 switch in the OT network at Level 1 the Purdue model-process control. The purpose of the Layer 2 switch is to segment traffic between PLC1 and PLC2 with two VLANs. All the traffic between PLC1 and PLC2 must first flow through the Layer 2 switch and then through the FortiGate device in the Level 2 supervisory control network.
What statement about the traffic between PLC1 and PLC2 is true?

  • A. The Layer 2 switch rewrites VLAN tags before sending traffic to the FortiGate device.
  • B. The Layer 2 switches routes any traffic to the FortiGate device through an Ethernet link.
  • C. PLC1 and PLC2 traffic must flow through the Layer-2 switch trunk link to the FortiGate device.
  • D. In order to communicate, PLC1 must be in the same VLAN as PLC2.

Answer : C

  • A. Configure a fabric connector with a notification policy on FortiSIEM to connect with FortiGate.
  • B. Create a notification policy and define a script/remediation on FortiSIEM.
  • C. Define a script/remediation on FortiManager and enable a notification rule on FortiSIEM.
