質問 # 57
Refer to the exhibit.
A partial Application Sensor profile is shown. When you apply this profile in firewall policy, which two statements are correct? (Choose two answers)
正解：B、D
解説：
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 .
質問 # 58
Refer to the exhibit.
An industrial Ethernet protocol skipping layers 3 to 6 is shown. Which industrial Ethernet protocol is it?
(Choose one answer)
正解：B
解説：
The correct answer is D. EtherCAT . The study guide explicitly states under the Ethernet/IP and EtherCAT section that "EtherCAT is a protocol that offers real-time communication in a primary-secondary configuration" and "EtherCAT skips layers 3 to 6 to deliver real-time communication." It also adds that
"the most important feature of this protocol is that secondary devices collect only the information they need from the data packets." This matches the exhibit exactly, where the diagram shows Real-Time Data above a Proprietary MAC and Proprietary physical layer , reflecting the protocol structure that bypasses the intermediate OSI layers.
The other options do not match this behavior. The guide says POWERLINK uses layer 2 and layer 7 of the OSI model, not that it skips layers 3 to 6. It also explains that Ethernet/IP is the industrial protocol based entirely on Ethernet standards and adapts to the OSI model. Modbus is described as an open client/server protocol and is not suitable for transmitting data in real time . Therefore, the protocol in the exhibit is clearly EtherCAT .

質問 # 60
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：B、D
質問 # 61
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：B、D
解説：
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.
