Fortinet NSE 7 - OT Security 6.4 Exam
Question 1
An OT network architect must deploy a solution to protect fuel pumps in an industrial remote
network. All the fuel pumps must be closely monitored from the corporate network for any
temperature fluctuations.
How can the OT network architect achieve this goal?
- A. Configure a fuel server on the remote network, and deploy a FortiSIEM with a single pattern temperature security rule on the corporate network.
- B. Configure a fuel server on the corporate network, and deploy a FortiSIEM with a single pattern temperature performance rule on the remote network.
- C. Configure a fuel server on the remote network, and deploy a FortiSIEM with a single pattern temperature performance rule on the corporate network.
- D. Configure both fuel server and FortiSIEM with a single-pattern temperature performance rule on the corporate network.
Answer:
B
Question 2
Refer to the exhibit.
An OT architect has implemented a Modbus TCP with a simulation server Conpot to identify and
control the Modus traffic in the OT network. The FortiGate-Edge device is configured with a software
switch interface ssw-01.
Based on the topology shown in the exhibit, which two statements about the successful simulation
of traffic between client and server are true? (Choose two.)
- A. The FortiGate-Edge device must be in NAT mode.
- B. NAT is disabled in the FortiGate firewall policy from port3 to ssw-01.
- C. The FortiGate devices is in offline IDS mode.
- D. Port5 is not a member of the software switch.
Answer:
A, C
Question 3
As an OT administrator, it is important to understand how industrial protocols work in an OT network.
Which communication method is used by the Modbus protocol?
- A. It uses OSI Layer 2 and the primary device sends data based on request from secondary device.
- B. It uses OSI Layer 2 and both the primary/secondary devices always send data during the communication.
- C. It uses OSI Layer 2 and both the primary/secondary devices send data based on a matching token ring.
- D. It uses OSI Layer 2 and the secondary device sends data based on request from primary device.
Answer:
D
Question 4
What can be assigned using network access control policies?
- A. Layer 3 polling intervals
- B. FortiNAC device polling methods
- C. Logical networks
- D. Profiling rules
Answer:
D
Question 5
Refer to the exhibit.
Based on the Purdue model, which three measures can be implemented in the control area zone
using the Fortinet Security Fabric? (Choose three.)
- A. FortiGate for SD-WAN
- B. FortiGate for application control and IPS
- C. FortiNAC for network access control
- D. FortiSIEM for security incident and event management
- E. FortiEDR for endpoint detection
Answer:
B, C, D
Question 6
An OT supervisor needs to protect their network by implementing security with an industrial
signature database on the FortiGate device.
Which statement about the industrial signature database on FortiGate is true?
- A. A supervisor must purchase an industrial signature database and import it to the FortiGate.
- B. An administrator must create their own database using custom signatures.
- C. By default, the industrial database is enabled.
- D. A supervisor can enable it through the FortiGate CLI.
Answer:
D
Question 7
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 logs to be indexed in FortiAnalyzer.
- B. The administrator selected the wrong time period for the report.
- C. The administrator selected the wrong devices in the Devices section.
- D. The administrator selected the wrong hcache table for the report.
Answer:
B, D
Question 8
What triggers Layer 2 polling of infrastructure devices connected in the network?
- A. A failed Layer 3 poll
- B. A matched security policy
- C. A matched profiling rule
- D. A linkup or linkdown trap
Answer:
D
Question 9
What two advantages does FortiNAC provide in the OT network? (Choose two.)
- A. It can be used for IoT device detection.
- B. It can be used for industrial intrusion detection and prevention.
- C. It can be used for network micro-segmentation.
- D. It can be used for device profiling.
Answer:
C, D
Question 10
When device profiling rules are enabled, which devices connected on the network are evaluated by
the device profiling rules?
- A. Known trusted devices, each time they change location
- B. All connected devices, each time they connect
- C. Rogue devices, only when they connect for the first time
- D. Rogue devices, each time they connect
Answer:
C
