Question 3

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.

Options:

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.

Question 4

An OT administrator is defining an incident notification policy using FortiSIEM and would like to configure the system with a notification policy.

Which step must the administrator take to achieve this task?

Options:

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.

Define a script/remediation on FortiManager and enable a notification rule on FortiSIEM.

D.

Deploy a mitigation script on Active Directory and create a notification policy on FortiSIEM.

Question 5

Which statemenl about the IEC 104 protocol is true?

Options:

IEC 104 is IEC 101 compliant in old SCADA systems.

C.

IEC 104 protects data transmission between OT devices and services.

D.

IEC 104 uses non-TCP/IP standards.

C.

port1-vlan10 and port2-vlan10 are part of the same broadcast domain

D.

port1, port1-vlan10, and port1-vlan1 are in different broadcast domains

Question 8

Which statement is correct about processing matched rogue devices by FortiNAC?

Options:
