質問 # 38
You want to gain complete visibility of the entire attack surface using FortiAnalyzer.
Which two views must you use to achieve this result? (Choose two.)
正解：A、C
解説：
The correct answers are C and E . Fortinet states that the SOC Dashboard provides an effective visualization of reported incidents and events and, through Security Fabric integration, enables administrators to gain complete visibility of the entire attack surface . The MITRE ATT CK Attack view complements this by presenting incident and event information according to ATT & CK-defined attack tactics and techniques, allowing analysts to understand where observed activity maps into known adversary behavior. The MITRE Coverage view has a different purpose-it measures event-handler coverage-while the Attack view focuses on actual incidents and events. Risk Summary and Resources Reports are associated primarily with FortiSIEM reporting functions, and Analytics Search is a query and investigation mechanism rather than a consolidated attack-surface view. Therefore, the required FortiAnalyzer views are MITRE ATT & CK Attack and SOC Dashboard .
質問 # 39
What are two advantages provided by industrial Ethernet? (Choose two answers)
正解：B、C
解説：
The correct answers are B. Real-time control and D. Determinism . The study guide defines industrial Ethernet as the "use of Ethernet and TCP/IP as transport mechanisms for industrial protocols" and states that it provides "real-time control," "low latency," and "determinism (meaning reliable and predictable data delivery)" in harsh environments. It further explains that industrial Ethernet "provides deterministic communication between machine controllers, actuators, sensors, and other units." These statements directly confirm that the two key advantages are real-time control and determinism.
The other options are not supported by the study guide as core advantages of industrial Ethernet. Encryption is not listed as one of the benefits in this section, and remote access is discussed elsewhere in the OT architecture but not as a defining advantage of industrial Ethernet itself. The guide is explicit that the main benefits here are predictable delivery and real-time communication, which are essential in industrial control environments where timing and reliability matter.
質問 # 40
For the installation of your first FortiGate device, you want to minimize the impact in your OT network.
Therefore, you deploy it initially as an offline IDS. Which two statements about this deployment are correct?
(Choose two answers)
正解：A、C
質問 # 41
Refer to the exhibit.
A simplified OT network is shown. You want to optimize the protection of this OT network. Which two controls must you implement? (Choose two answers)
正解：B、D
解説：
The correct answers are B. IPS on FortiGate_Level5 and C. Virtual patching on FortiGate_Level2 .
The study guide explains that "the first line of defense is securing the IT side of your network" and that FortiGate should be placed to protect ICS environments and stop threats from propagating from IT into OT. It also states that IPS improves OT security because "today's threat landscape requires IPS to block a wider range of threats and improve OT security" and that in IPS mode, vulnerable devices are protected . This makes FortiGate_Level5 , at the upper boundary near the DMZ and external connectivity, the correct place to implement IPS as a primary protection control.
The study guide also states in the Purdue model section that "Level 2 consists of the processes and programs that control the PLCs, RTUs, and IEDs found at Level 1" and that "it is necessary to segment, or even microsegment, these servers with firewall segmentation, along with policies that include application control and virtual patching." In addition, the virtual patching section says "Virtual patching protects OT devices that have not yet been updated against vulnerability exploits" and applies when traffic related to the vulnerable device reaches the firewall policy. Since FortiGate_Level2 sits between the process network and the control network, it is the right enforcement point for virtual patching to protect the PLC-side assets.
Option A is not one of the best answers because offline IDS only detects and logs attacks; the guide says "no traffic flows through FortiGate" in offline IDS mode, whereas IPS can actually block threats. Option D is also not the best answer because OT signatures are enabled within the IPS framework, but the stronger control explicitly described for this design is to deploy IPS at the upper boundary and virtual patching closer to vulnerable OT devices .
質問 # 42
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?
正解：D
解説：
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.
