- A. IT and OT networks are separated by segmentation.
- B. Micro-segmentation can be achieved only by replacing FortiGate-3 and FortiGate-4 with a pair of FortiSwitch devices.
- C. FortiGate-3 and FortiGate-4 devices must be in a transparent mode.
- D. Firewall policies should be configured on FortiGate-3 and FortiGate-4 with industrial protocol sensors.

質問 21
When device profiling rules are enabled, which devices connected on the network are evaluated by the device profiling rules?
- A. Rogue devices, each time they connect
- B. Known trusted devices, each time they change location

質問 22
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. In order to communicate, PLC1 must be in the same VLAN as PLC2.
- B. The Layer 2 switches routes any traffic to the FortiGate device through an Ethernet link.
- C. The Layer 2 switch rewrites VLAN tags before sending traffic to the FortiGate device.
- D. PLC1 and PLC2 traffic must flow through the Layer-2 switch trunk link to the FortiGate device.
正解: D
質問 23
An OT network architect needs to secure control area zones with a single network access policy to provision devices to any number of different networks.
On which device can this be accomplished?
- A. FortiNAC
- B. FortiEDR
- C. FortiSwitch
- D. FortiGate
正解: A
質問 24
An administrator wants to use FortiSoC and SOAR features on a FortiAnalyzer device to detect and block any unauthorized access to FortiGate devices in an OT network.
Which two statements about FortiSoC and SOAR features on FortiAnalyzer are true? (Choose two.)
- A. Each playbook can include multiple triggers.
- B. You cannot use Windows and Linux hosts security events with FortiSoC.
- C. You can automate SOC tasks through playbooks.
- D. You must set correct operator in event handler to trigger an event.
正解: A,C

質問 25
An OT administrator configured and ran a default application risk and control report in FortiAnalyzer to learn more about the key application crossing the network. However, the report output is empty despite the fact that some related real-time and historical logs are visible in the FortiAnalyzer.
What are two possible reasons why the report output was empty? (Choose two.)
- A. The administrator selected the wrong time period for the report.
- B. The administrator selected the wrong hcache table for the report.
- C. The administrator selected the wrong devices in the Devices section.
- D. The administrator selected the wrong logs to be indexed in FortiAnalyzer.
正解: A,B
質問 26
