NSE6_OTS_AR-7.6 Dumps with Practice Exam Questions Answers

The correct answers are C and D .

Option C is correct because the study guide explains that when “a handler generates an event with the automation stitch option enabled, FortiAnalyzer sends a notification” and, in the Security Fabric workflow, “FortiAnalyzer parses the logs and notifies the root FortiGate.” This means FortiGate must first have the FortiAnalyzer connection configured so it can consume FortiAnalyzer event handlers and use them in automation. The wizard message in the exhibit also points to this requirement by indicating that a FortiAnalyzer connection must be configured.

Option D is also correct because the study guide explicitly says that in this automation flow “the root FortiGate triggers the action” and shows “Stitches configured on root FortiGate.” Therefore, if you want the FortiAnalyzer event handler to appear and be usable for automation, the trigger must be configured on the root FortiGate , not on an arbitrary downstream FortiGate.

Option A is incorrect because + Create is only a GUI control and does not solve the missing-event-handler visibility problem. Option B is not identified in the study guide as the requirement for making a FortiAnalyzer event handler available in the FortiGate automation trigger list.

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 .

According to the OT Security 7.6 Architect study guide section on Asset Management , specifically regarding FortiNAC Visibility :

Layer 2 Polling Data : Because each physical address is unique, FortiNAC identifies hosts as they connect to the network. The information gathered during this process fills in the physical address and location information in the database.

Visibility Components : The guide states that the physical address learned , the time it was learned , and where it was learned from provide the foundation of endpoint visibility in the form of " what, where, and when " information. This confirms that Where it was learned (Option A) and The time it was learned (Option D) are correct.

Exclusions :

Layer 3 Polling : The MAC-to-IP correlation (Option B) is explicitly defined as a function of Layer 3 polling , where the correlated IP address is added to the database record for the corresponding MAC address.

DHCP Fingerprinting : The host name or system name (Option C) and the operating system are gathered via DHCP fingerprinting , not layer 2 polling.

Deploying a FortiGate in offline IDS (also known as one-arm sniffer mode) is a common strategy in OT environments for several reasons found in the study guide:

Priority of Availability : In OT, availability and safety are critically important and prioritized higher than in IT. An offline IDS minimizes impact because it does not sit in the direct path of production traffic.

Network Sensor Role : In this mode, the FortiGate is connected to a mirror/SPAN port on a switch. It acts as a network sensor , receiving a copy of the traffic rather than having the traffic flow through it. This confirms Statement A is correct and Statement D is incorrect.

Passive vs. Active : The guide explicitly states that in OT environments, passive methods are preferred over active methods to avoid negatively impacting performance or causing process interruptions.

Depth of Visibility : Even though the device is offline, you apply security profiles (such as IPS, Application Control, and Antivirus) to the sniffer interface. This allows the FortiGate to analyze the copied traffic and provide deep visibility into the OT assets and their behaviors. This confirms Statement B is correct.

Detection vs. Prevention : An IDS (Intrusion Detection System) is passive ; it can detect threats but cannot reset connections or drop packets to block attacks. Therefore, it cannot block zero-day attacks, making Statement C incorrect.

The correct answer is C. EtherCAT .

The study guide states that for industrial Ethernet protocols, “such as Ethernet/IP and Modbus/TCP, you can use VLANs to segment your physical LAN into multiple logical LANs.” This directly confirms that Ethernet/IP and Modbus/TCP support VLAN-based segmentation in the OT context.

By contrast, the guide explains that “EtherCAT skips layers 3 to 6 to deliver real-time communication” and describes it as an “Open-Software Modified-Ethernet” approach. Because it does not operate like the standard Ethernet/IP model used for normal VLAN-based segmentation, EtherCAT is the protocol identified here as not supporting VLANs in the way Ethernet/IP and Modbus/TCP do.

So, based on the study guide comparison, the verified answer is EtherCAT .
