NSE7_OTS-7.2 Fortinet NSE 7 - OT Security 7.2 sample Question + Exam 2025 Practice Exam Dumps

Question # 4

An OT network consists of multiple FortiGate devices. The edge FortiGate device is deployed as the secure gateway and is only allowing remote operators to access the ICS networks on site.

Management hires a third-party company to conduct health and safety on site. The third-party company must have outbound access to external resources.

As the OT network administrator, what is the best scenario to provide external access to the third-party company while continuing to secure the ICS networks?

Configure outbound security policies with limited active authentication users of the third-party company.

Create VPN tunnels between downstream FortiGate devices and the edge FortiGate to protect ICS network traffic.

Split the edge FortiGate device into multiple logical devices to allocate an independent VDOM for the third-party company.

Implement an additional firewall using an additional upstream link to the internet.

Question # 10

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.)

The administrator selected the wrong logs to be indexed in FortiAnalyzer.

The administrator selected the wrong time period for the report.

The administrator selected the wrong devices in the Devices section.

The administrator selected the wrong hcache table for the report.

Question # 11

Which two frameworks are common to secure ICS industrial processes, including SCADA and DCS? (Choose two.)

Modbus

NIST Cybersecurity

IEC 62443

IEC104

Full Access

Answer:

B, C

Explanation:

B. NIST Cybersecurity Framework (CSF)

Role: Provides a risk-based approach to manage cybersecurity for critical infrastructure (including ICS/SCADA/DCS).

Fortinet Reference:

Fortinet OT Security Solution Guide (v7.2):

"The NIST Cybersecurity Framework is widely adopted in OT environments to align security practices with business objectives, manage risks, and ensure resilience."

Page 12: "Framework adoption (e.g., NIST CSF) helps organizations prioritize OT asset protection."

C. IEC 62443

Role: International standardÂ specifically designedÂ for ICS/OT security, covering technical controls, processes, and risk management.

Fortinet Reference:

*Fortinet NSE 7 - OT Security 7.2 Study Guide*:

"IEC 62443 is the foundational standard for securing industrial automation and control systems (IACS), including SCADA and DCS. It defines security zones, conduits, and security levels (SLT)."

*Module 4: "IEC 62443 provides OT-specific security requirements not covered by IT frameworks."*

Why Other Options Are Incorrect

A. Modbus: AÂ communication protocolÂ (not a framework) used in OT environments. It lacks security features and governance.

FortiGate OT Security Guide:

"Modbus is an unauthenticated, cleartext protocol vulnerable to eavesdropping. It is not a security framework."

D. IEC 104: AÂ telecontrol protocolÂ for SCADA (based on IEC 60870-5-104). It isÂ not a security framework.

FortiSIEM OT Monitoring Handbook:

"IEC 104 is used for data transmission in electrical grids. Like Modbus, it requires external security controls."

Key Documentation Extracts

Fortinet OT Security Solution Guide (v7.2):

*"Industrial environments align with IEC 62443 for OT-specific controls and NIST CSF for risk governance. Protocols like Modbus/IEC 104 require additional hardening."*

NSE 7 OT Security 7.2 Curriculum:

"IEC 62443 addresses OT asset discovery, segmentation, and threat detection. NIST CSF complements it with risk assessment methodologies."

Question # 12

Refer to the exhibit.

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

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

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

IT and OT networks are separated by segmentation.

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

Full Access

Question # 13

Refer to the exhibit and analyze the output.

Which statement about the output is true?

This is a sample of a FortiAnalyzer system interface event log.

This is a sample of an SNMP temperature control event log.

This is a sample of a PAM event type.

This is a sample of FortiGate interface statistics.

Question # 14

You are investigating a series of incidents that occurred in the OT network over past 24 hours in FortiSIEM.

Which three FortiSIEM options can you use to investigate these incidents? (Choose three.)

Security

IPS

List

Risk

Overview

Full Access

Question # 15

Which three criteria can a FortiGate device use to look for a matching firewall policy to process traffic? (Choose three.)

Services defined in the firewall policy.

Source defined as internet services in the firewall policy

Lowest to highest policy ID number

Destination defined as internet services in the firewall policy

Highest to lowest priority defined in the firewall policy

Full Access

Question # 16

Refer to the exhibit.

Which statement is true about application control inspection?

The industrial application control inspection process is unique among application categories.

Security actions cannot be applied on the lowest level of the hierarchy.

You can control security actions only on the parent-level application signature

The parent signature takes precedence over the child application signature.

Full Access

Question # 17

When device profiling rules are enabled, which devices connected on the network are evaluated by the device profiling rules?

Known trusted devices, each time they change location

All connected devices, each time they connect

Rogue devices, only when they connect for the first time

Rogue devices, each time they connect

Full Access

Question # 18

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?

FortiGate determined the user by passive authentication

The user was determined by Security Fabric

Two-factor authentication is not configured with RADIUS authentication method

FortiNAC determined the user by DHCP fingerprint method

Full Access

Question # 19

Refer to the exhibit.

The IPS profile is added on all of the security policies on FortiGate.

For an OT network, which statement of the IPS profile is true?

FortiGate has no IPS industrial signature database enabled.

The listed IPS signatures are classified as SCADA equipment.

All IPS signatures are overridden and must block traffic match signature patterns.

The IPS profile inspects only traffic originating from SCADA equipment.

Full Access

Question # 20

How can you achieve remote access and internet availability in an OT network?

Create a back-end backup network as a redundancy measure.

Implement SD-WAN to manage traffic on each ISP link.

Add additional internal firewalls to access OT devices.

Create more access policies to prevent unauthorized access.
