Fortinet Fortinet Certifications NSE7_OTS-6.4 Questions & Answers

• Question 11:

  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.

  Correct Answer: AC

• Question 12:

  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.

  Correct Answer: B

• Question 13:

  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. You must set correct operator in event handler to trigger an event.

  B. You can automate SOC tasks through playbooks.

  C. Each playbook can include multiple triggers.

  D. You cannot use Windows and Linux hosts security events with FortiSoC.

  Correct Answer: BC

• Question 14:

  Refer to the exhibit.

  

  Given the configurations on the FortiGate, which statement is true?

  A. FortiGate is configured with forward-domains to reduce unnecessary traffic.

  B. FortiGate is configured with forward-domains to forward only domain controller traffic.

  C. FortiGate is configured with forward-domains to forward only company domain website traffic.

  D. FortiGate is configured with forward-domains to filter and drop non-domain controller traffic.

  Correct Answer: A

• Question 15:

  An OT administrator has configured FSSO and local firewall authentication. A user who is part of a user group is not prompted from credentials during authentication.

  What is a possible reason?

  A. FortiGate determined the user by passive authentication

  B. The user was determined by Security Fabric

  C. Two-factor authentication is not configured with RADIUS authentication method

  D. FortiNAC determined the user by DHCP fingerprint method

  Correct Answer: D

• Question 16:

  An OT supervisor has configured LDAP and FSSO for the authentication. The goal is that all the users be authenticated against passive authentication first and, if passive authentication is not successful, then

  users should be challenged with active authentication. What should the OT supervisor do to achieve this on FortiGate?

  A. Configure a firewall policy with LDAP users and place it on the top of list of firewall policies.

  B. Enable two-factor authentication with FSSO.

  C. Configure a firewall policy with FSSO users and place it on the top of list of firewall policies.

  D. Under config user settings configure set auth-on-demand implicit.

  Correct Answer: D

• Question 17:

  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. FortiGate

  B. FortiEDR

  C. FortiSwitch

  D. FortiNAC

  Correct Answer: D

• Question 18:

  Refer to the exhibit.

  

  Based on the topology designed by the OT architect, which two statements about implementing OT security are true? (Choose two.)

  A. Firewall policies should be configured on FortiGate-3 and FortiGate-4 with industrial protocol sensors.

  B. Micro-segmentation can be achieved only by replacing FortiGate-3 and FortiGate-4 with a pair of FortiSwitch devices.

  C. IT and OT networks are separated by segmentation.

  D. FortiGate-3 and FortiGate-4 devices must be in a transparent mode.

  Correct Answer: CD

• Question 19:

  Which three methods of communication are used by FortiNAC to gather visibility information? (Choose three.)

  A. SNMP

  B. ICMP

  C. API

  D. RADIUS

  E. TACACS

  Correct Answer: ACD

• Question 20:

  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.

  Correct Answer: C
