NEW QUESTION # 21
Match each industrial protocol to its corresponding characteristics.
Select each OT industrial protocol in the column on the left and drag and drop it into the blank space next to its corresponding characteristic in the column on the right. You must match all four industrial protocols to their characteristics in the work area.
Answer:
Explanation:
Explanation:
Industrial Protocol
Correct Characteristic
POWERLINK
Mainly used for the transmission of process data
EtherCAT
Offers real-time data transmission in a primary-secondary configuration Modbus Uses client/server communication Ethernet/IP Based entirely on Ethernet standards The correct mappings follow the industrial Ethernet characteristics defined in the OT Security 7.6 curriculum.
Ethernet/IP is the industrial protocol based entirely on Ethernet standards and adapts to the standard Ethernet
/TCP-IP architecture. EtherCAT is designed for deterministic real-time communication and specifically operates in a primary-secondary configuration while bypassing OSI layers 3 through 6. POWERLINK is an open real-time industrial Ethernet protocol that uses OSI layers 2 and 7 and is mainly intended for transmitting process data. Modbus , by contrast, uses a client/server communication model in which the server responds only after receiving a request from a client; it is not considered a real-time transmission protocol. These distinctions uniquely determine all four drag-and-drop placements.
NEW QUESTION # 22
Refer to the exhibit.
A Logical Topology page of a FortiGate device is shown. Your OT company wants to gain visibility into the network. You decide to implement device detection with the Security Fabric. Based on the exhibit, which statement is correct? (Choose one answer)
Answer: D
Explanation:
The correct answer is A. Device Detection is enabled on the other identified device .
The study guide explains that device identification is a "useful feature for the Security Fabric topology view" and that "FortiGate detects most third-party devices in your network and adds them to the topology view of the Security Fabric." It also states that in the interfaces section, you can enable device detection , and this detection is what allows FortiGate to identify devices based on observed traffic.
In the exhibit, the tooltip distinguishes between "1 device requires authorization" and "1 other identified device." That means the unauthorized device is a separate FortiGate/Fabric member issue, while the other identified device is simply a detected third-party device shown in the topology because device detection is working. Therefore, the correct interpretation is that device detection is enabled for that identified device.
Option B is incorrect because the exhibit does not say the other identified device requires authorization.
Option C is not supported by the study guide, and option D is too specific because no evidence in the exhibit confirms that the detection was enabled specifically on port3 .
NEW QUESTION # 23
In the Purdue model, at which level are physical assets like the Industrial Internet of Things (IIoT) placed?
(Choose one answer)
Answer: C
Explanation:
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 .
NEW QUESTION # 24
During layer 2 polling , which two pieces of information are gathered by FortiNAC to identify a device?
(Choose two answers)
Answer: B,C
Explanation:
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.
NEW QUESTION # 25
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)
Answer: A,D
Explanation:
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 .
