質問 # 19
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：C
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 # 20
You want to improve access control for your large OT network using passive authentication. What must you configure on FortiGate? (Choose one answer)
正解：C
解説：
The correct answer is A. Fortinet Single-Sign On (FSSO) . The study guide states under Active and Passive Authentication that for passive authentication, "User does not receive a login prompt from FortiGate" ,
"Credentials are determined automatically" , and specifically "FSSO, RSSO, and NTLM can be used." It then explains that passive authentication occurs with the single sign-on method and explicitly identifies Fortinet SSO (FSSO) as one of those methods.
The guide also says: "For passive authentication, you can implement FSSO. FSSO allows users who have already authenticated on the network through another system to be transparently identified. After initial login to any system on the network, users can access allowed resources without being prompted for credentials." That is exactly what the question asks for: improving access control in a large OT network using passive authentication .
The other options do not match passive authentication. Local users are part of local authentication, two- factor authentication adds an extra security factor but still uses active authentication, and FortiAuthenticator as a remote server supports centralized authentication for mid-to-large networks, but by itself it is not the specific passive-authentication method being asked here. The study guide is explicit that the FortiGate configuration for passive authentication is FSSO .
質問 # 21
In the Purdue model, at which level are physical assets like the Industrial Internet of Things (IIoT) placed?
(Choose one answer)
正解：D
解説：
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 .
質問 # 22
Refer to the exhibit.
A partial Application Sensor profile is shown. When you apply this profile in a firewall policy, which two statements are correct? (Choose two answers)
正解：C、D
解説：
The correct answers are A and C .
Option C is correct because the profile clearly contains the Operational Technology category and specific OT application signatures such as Modbus and IEC.60870.5.104 . The study guide says "You can use application control signatures to detect OT protocols" and "You can filter to a specific OT protocol." That means OT application signatures are active in this sensor profile.
Option A is correct because the guide explains that application control works at different levels: "Detection of protocol (one detection per session)" and "Message level (one detection per protocol message)." It also says you can use application signatures for "granular message type identification." In the exhibit, IEC.
60870.5.104.Control.Functions is explicitly configured, which is a granular IEC message/control-level signature rather than only a protocol-level match. That means logging and control can occur at the IEC command level.
Option B is not correct because the profile shows Modbus configured at the parent protocol level as Monitor
, while the guide states that the "parent signature takes precedence over the child signature." Since protocol-level detection is one detection per session , that does not mean FortiGate will necessarily log each Modbus command individually.
Option D is incorrect because even though the broader Operational Technology category is set to block, the profile includes specific application and filter overrides for Modbus and IEC 104 behavior. So the resulting effect is not simply that all OT protocols are blocked .
質問 # 23
In your OT environment, you want to detect the devices passively. Which two methods must you implement?
(Choose two answers)
正解：A、D
解説：
The correct answers are C. Vendor OUI and D. Network traffic .
The study guide explicitly separates active/direct profiling methods from passive/non-direct methods and states that "In OT environments, passive methods are preferred over active methods." It then lists the methods that do not require FortiNAC to interact directly with the device being profiled. Among those methods are "Network traffic: gathered from the infrastructure" and "Vendor OUI: determined by the MAC address gathered from the infrastructure." That directly matches options C and D .
Options A and B are incorrect because SSH and SNMP are shown in the guide under the direct/active profiling methods. The guide's point is that passive detection avoids directly scanning or interacting with OT endpoints, since that can negatively affect performance in industrial environments. Because the question specifically asks for passive detection methods, the correct pair is Vendor OUI and Network traffic .
