問題 #33
Refer to the exhibit.
A partial OT network is shown.
You have recently removed the air gap in the network to provide full connectivity.
What must you configure to protect your OT network from external attacks?
答案：D
解題說明：
The correct answer is D . Removing the air gap creates connectivity between the OT environment and external networks, significantly increasing exposure to unauthorized access and cyberattacks. Fortinet explains that the expansion of remote connectivity and IT/OT interconnections increases the OT attack surface and that the modern threat landscape requires IPS to block a wider range of threats . In the shown Purdue-style topology, FortiGate_Level5 is positioned at the upper boundary toward external connectivity and is therefore the appropriate enforcement point for protecting against attacks entering from outside the OT environment. Virtual patching at Level 2 is intended primarily to compensate for known vulnerabilities on specific OT devices that cannot yet be patched. Application Control provides industrial protocol visibility and command-level control, while merely enabling OT signatures at Level 3 does not replace perimeter intrusion prevention. Consequently, IPS belongs on FortiGate_Level5 .
問題 #34
Refer to the exhibit.
A partial OT network is shown. You have encountered many disconnections in the links and want to improve the availability of this network. Which action can you perform? (Choose one answer)
答案：D
解題說明：
The correct answer is C. You can implement parallel redundancy protocol . The study guide explains that media redundancy involves creating a backup path that can be used when part of the network fails and specifically states that "Parallel Redundancy Protocol (PRP) can be used for a star topology." Since the problem described is many disconnections in the links , the issue is link availability, which is a media redundancy problem rather than a firewall virtualization or policy separation problem. PRP is designed to provide a backup communication path with low recovery time when links fail.
The other options do not fit this scenario as well. HA clusters are described in the guide as a solution for network node redundancy , where a backup firewall or switch takes over when the primary device fails. SD- WAN is recommended for remote site access across multiple WAN links, not for the local floor links shown in this topology. VDOMs provide logical segmentation, not link redundancy or higher link availability.
Because the question is specifically about repeated link disconnections , the best action is to implement PRP .
問題 #35
Refer to the exhibit.
A partial OT network is shown.
PLC-1 has a known critical vulnerability, but you cannot update it.
What must you configure to protect PLC-1?
答案：A
解題說明：
The correct answer is C . This scenario is the precise use case for virtual patching . The OT Security 7.6 study guide states that virtual patching protects OT devices that have not yet been updated against vulnerability exploits . FortiGate identifies the vulnerable asset, queries FortiGuard for device-specific vulnerabilities and mitigation rules, receives applicable OT virtual-patching signatures, and maps those rules to the device. When traffic associated with the vulnerable asset reaches FortiGate, the firewall policy containing the virtual-patching profile applies the protection. In the topology, FortiGate_Level2 is the enforcement point immediately protecting PLC-1 and the control-network assets. IPS at Level 5 provides broader perimeter protection, but it is not the device-specific compensating control requested here.
Application Control primarily regulates industrial protocols and commands. Therefore, Virtual patching on FortiGate_Level2 is required.
問題 #36
Refer to the exhibit.
An automation trigger creation wizard is shown. You want to automate some tasks in your OT network. In a FortiGate device, you create a new automation trigger based on a FortiAnalyzer event handler. When you want to configure the Event handler name field, the event handler created in FortiAnalyzer is not shown.
What are two reasons for this? (Choose two answers)
答案：A,B
解題說明：
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.
問題 #37
Refer to the exhibit.
A basic event handler is shown. You have enabled Automation Stitch to automate the handling of an alert.
Which two steps must you take to use this automation stitch? (Choose two answers)
答案：A,B
解題說明：
The correct answers are C and D .
Option D is correct because the study guide states that the configuration of an event handler can include
"Rules" and explains that "Rules are granular conditions" and "Event handlers can have one or more rules." It further states that "FortiAnalyzer uses event handlers to filter all incoming logs" and "If logs match the conditions configured in an event handler, FortiAnalyzer generates an event." Therefore, to use the automation stitch, you must define the rules on FortiAnalyzer so the event handler can actually generate the event that starts the automation flow.
Option C is also correct. The study guide explains that "When a handler generates an event with the automation stitch option enabled, FortiAnalyzer sends a notification" to the FortiGate side, and in the attack-detection example it says "FortiAnalyzer parses the logs and notifies the root FortiGate" and then
"The root FortiGate triggers the action." It also explicitly shows "Stitches configured on root FortiGate." This means the FortiGate must have the corresponding automation trigger configured for the FortiAnalyzer event handler notification.
Option A is incorrect because the study guide does not describe configuring an Action on FortiAnalyzer as the required step for this FortiAnalyzer-to-FortiGate automation-stitch flow. Option B is also incorrect because playbooks are a different FortiAnalyzer automation mechanism; the question specifically refers to using the Automation Stitch option in the event handler.
