Fortinet Fortinet NSE 6 - OT Security 7.6 Architect NSE6_OTS_AR-7.6 Exam Dumps: Updated Questions & Answers (April 2026)

The correct answers are A and B .

Option B is correct because the study guide states that “When a handler generates an event with the automation stitch option enabled, FortiAnalyzer sends a notification” to FortiGate. If Automation Stitch is not enabled in the FortiAnalyzer event handler, that handler will not be usable for the FortiGate automation-stitch workflow. The guide also explains that the configuration of each event handler can include “Automation stitches” and “Rules,” showing that this is a required part of the FortiAnalyzer-to-FortiGate automation path.

Option A is also correct. The study guide explains the automation flow in the Security Fabric: “FortiAnalyzer parses the logs and notifies the root FortiGate” and then “The root FortiGate triggers the action.” That means FortiGate must have the FortiAnalyzer connection configured through the Security Fabric side before it can consume FortiAnalyzer event handlers. The warning in the exhibit about configuring a FortiAnalyzer connection also points directly to that requirement.

Option C is incorrect because + Create is not the reason the existing event handler is missing; it is only an interface control. Option D is not the best answer for this item because the question is about why the event handler name list on FortiGate is empty for FortiAnalyzer-triggered automation. The study guide’s verified requirements for that workflow are the FortiAnalyzer-to-FortiGate Fabric connection and enabling Automation Stitch on the FortiAnalyzer event handler.

Based on the provided exhibits from the FortiAnalyzer playbook engine:

Playbook Trigger Condition : The Partial Playbook configuration exhibit shows that the playbook is set to trigger based on a condition where the Basic Handler Name is Equal To IPS_Attack_Handling.

Event vs. Log : In FortiAnalyzer, the field Basic Handler Name is a property of an Event record, indicating the specific Event Handler that generated it. A playbook configured with this condition is triggered by an Event , not directly by a raw log.

Playbook Execution Flow : The Partial Playbook Monitor view shows the execution sequence:

Event_Trigger (Starter) : This is the entry point of the playbook, which matches the condition defined in the configuration.

IPS_Attack_Incident : The first task executed after the trigger.

Run_Report : The task in question, which is executed as part of the automated workflow initiated by the starter.

Conclusion : Since the playbook's "Starter" is defined by the IPS_Attack_Handling handler name, an event produced by that handler is the root trigger for the entire playbook execution, including the Run_Report task.

Therefore, the Run_Report task was triggered (as part of the playbook) by an IPS_Attack_Handling event .

Based on the architecture of FortiAnalyzer within the Security Fabric and its automation capabilities:

Automation Stitch and Reports : Within the Security Fabric environment, FortiAnalyzer serves as a key element in creating automation stitches and playbooks. For a report to be selectable within a Playbook task (such as the Run_report task shown in the exhibit), it must meet specific technical prerequisites in the report configuration.

Auto-cache Requirement (Answer C) : For a report to be used for automated generation, it must be "ready" to be processed by the engine without manual intervention. Auto-cache must be enabled in the report settings to ensure the report can be generated dynamically and efficiently when triggered by the playbook.

Extended Log Filtering (Answer B) : Playbooks often pass specific variables from the trigger (such as a specific device IP or a time range) into the report. For the report to accept these dynamic parameters and be visible as an "automation-compatible" report in the Playbook interface, Extended Log Filtering must be enabled.

Workflow Constraints : Without these two settings enabled on the report itself, the Playbook engine cannot guarantee the report's successful generation or parameter injection, and thus filters it out of the available selection list in the Run_report task.

The verified answer is C. The Fabric settings . The study guide ties FortiAnalyzer-triggered actions to the Security Fabric relationship with FortiGate, not to playbook tasks or standalone event handlers alone. It explains that “within the Security Fabric environment, FortiAnalyzer is a key element in the creation of automation stitches” and shows the flow where a downstream FortiGate sends logs to FortiAnalyzer, then FortiAnalyzer parses the logs and notifies the root FortiGate , after which the root FortiGate triggers the action . This shows that FortiAnalyzer must be configured so it can communicate with FortiGate through the Security Fabric.

The guide also states that FortiAnalyzer is the foundation of the Security Fabric , providing logging, reporting, analytics, and automation for Fabric devices and endpoints. It further explains that the FortiAnalyzer Fabric connector consolidates the traffic logs within the Security Fabric. This confirms that the automation workflow depends on proper Security Fabric integration. A playbook task is used for automated SOC actions, and an event handler is used to generate events from logs, but neither one alone establishes the direct communication path needed between FortiAnalyzer and FortiGate. Therefore, the required configuration on FortiAnalyzer is the Fabric settings .

The correct answer is C. Application sensor set to monitor on all the FortiGate devices .

The study guide clearly explains that application control is the feature used to identify OT protocols. It states that “application control detects the protocols used in applications like Modbus, IEC 104, and the contents of the telecontrol messages” and also says “You can use application control signatures to detect OT protocols.” It further shows an example where a Modbus application control profile is enabled on a firewall policy “for OT protocol visibility in the monitor status.” This directly matches the requirement in the question, which is to detect OT protocols and increase traffic visibility .

The other options do not fit the requirement as precisely. Device detection is for identifying devices and collecting endpoint information, not for detecting industrial protocols. Inline IDS and IPS are focused more on detecting or blocking attacks, exploits, protocol abnormalities, and known vulnerabilities. While IPS can inspect some OT traffic, the study guide distinguishes it from application control by stating that IPS signatures tend to detect exploits, whereas application control signatures tend to provide protocol detection at various levels . Therefore, the required security sensor for OT protocol detection and traffic visibility is the application sensor in monitor mode .

The correct answers are A and C . The study guide explains that “You can use application control signatures to detect OT protocols” and that application control provides “granular message type identification.” In the exhibit, the Operational Technology application category is included in the Application Sensor profile, so OT application signatures are enabled in this profile.

Option C is also correct because the override table shows Modbus_Read.Holding.Registers = Allow and Modbus = Block . The study guide states that you can use specific granular application control signatures to allow a specific Modbus command and block all others , and it also shows that application control can identify read and write commands separately at message level. Therefore, Modbus write commands are blocked by this profile.

Option B is incorrect because the profile is not simply monitoring all OT protocols; it contains a Block action for Modbus. Option D is incorrect because the study guide links OT protocol visibility specifically to the monitor status , while in the exhibit Modbus_Read.Holding.Registers is set to Allow , not Monitor .

The correct answers are B and C . The study guide states that “You can use application control signatures to detect OT protocols” and that “Application control detects the protocols used in applications like Modbus, IEC 104, and the contents of the telecontrol messages” . It also shows that a Modbus application control profile can be enabled on a firewall policy “for OT protocol visibility in the monitor status.” This directly supports B , because application control is the feature used to identify and monitor OT protocols on FortiGate.

The guide also explains under IPS that “By default, OT signatures are excluded from the signatures lists on the GUI until you enable them on the CLI” using config ips global and set exclude-signatures none . Once enabled, FortiGate can use those OT signatures for OT-aware inspection and protection. That supports C as the second required configuration. A is related to device discovery, not protocol identification, and D is focused on exploit and vulnerability detection rather than the first-step goal of identifying OT protocols.

Based on the OT Security 7.6 Architect study guide regarding the Asset Identity Center and Asset Management :

Vulnerability Visibility : The Asset Identity List tab displays key metadata for IT and OT devices, including detected addresses, users, and a specific column for Vulnerabilities .

Virtual Patching Feature : In the OT Security 7.6 architecture, the "Vulnerabilities" column is populated through the OT Security Service license, which includes " OT vulnerability correlation definitions & virtual patching signatures ".

Correlation Mechanism : FortiGate extracts metadata from OT traffic and uses these signatures to identify known vulnerabilities on the assets. For these vulnerabilities to be identified and correlated in the Asset Identity Center as shown in the exhibit (displaying a count of 8 vulnerabilities), the Virtual Patching feature must be active.

Architectural Implementation : Virtual patching is a critical component of the "Protection" layer in OT networks, allowing administrators to secure legacy or unpatchable PLCs and RTUs by blocking exploit attempts at the network level using IPS-based virtual patching signatures.

Exhibit Analysis : The presence of identified vulnerabilities (the number "8" in the red shield) in the Asset Identity List confirms that the FortiGate is actively performing vulnerability correlation, which is the operational result of having a Virtual Patching security profile applied to the relevant firewall policy.

The correct answers are A and D . The study guide provides a direct use case called Attack Detection and Automated Alert . It states: “A downstream FortiGate detects an attack and sends logs to FortiAnalyzer. FortiAnalyzer parses the logs and notifies the root FortiGate. The root FortiGate triggers the action, which in this case, is a notification to the administrator.” The same slide also explicitly shows “Stitches configured on root FortiGate.” This confirms that to send the automated alert, you must configure the automation stitch on the root FortiGate .

The second required configuration is an event handler on FortiAnalyzer . The guide explains that “Event handlers generate events” and that “FortiAnalyzer uses event handlers to filter all incoming logs. If logs match the conditions configured in an event handler, FortiAnalyzer generates an event.” Since FortiAnalyzer must detect the attack from the received logs before notifying the root FortiGate, an event handler is required on FortiAnalyzer.

Option B is incorrect because the study guide does not identify a LOCALHOST task as the required configuration for this attack-alert flow. Option C is also incorrect because the question asks what must be configured to enable the automated alert workflow . An IPS profile may detect some attacks, but the required automation path in the study guide is specifically event handler on FortiAnalyzer + stitch on the root FortiGate .

According to the OT Security 7.6 Architect study guide regarding the Purdue Model :

Asset Location : The study guide states that "All critical physical assets are located on the plant floor and equipped with IIoT sensors."

Level Classification : The "plant floor" is further defined as the "control area zone," which consists of Levels 0, 1, and 2 .

Hierarchy : The "Operations & Control" zone is identified as Level 3 and Level 3.5 .

Direct Answer : In the "Introduction" lesson's Knowledge Check , the specific question "In the Purdue model, at which level are IIoTs placed?" is provided with the verified answer: Below Level 3.5 .
