NEW QUESTION # 37
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?
Answer: B
Explanation:
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.
NEW QUESTION # 38
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 # 39
According to the IEC 62443 standard, your security level is 4 . What is your OT environment defending against? (Choose one answer)
Answer: D
Explanation:
According to the OT Security 7.6 Architect study guide regarding IEC 62443 Security Levels :
* Security Level 4 (SL 4) Definition : This level provides " Protection against intentional violation using sophisticated means with extended resources, specific skills, and high motivation " .
* Real-World Application : The study guide specifically notes: " If you are facing a syndicate of cyber extortionists with extensive resources and capabilities, then you should strive for security level 4 " .
* Comparison to other levels :
* SL 1 : Protection against " casual or unintentional system violation " .
* SL 2 : Protection against " intentional violation using simple means with low resources " .
* SL 3 : Protection against " intentional violation using sophisticated means with moderate resources " .
NEW QUESTION # 40
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)
Answer: A,C
Explanation:
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.
NEW QUESTION # 41
Refer to the exhibit.
A partial OT network is shown. You have configured the FortiGate device with VLANs to segment the OT network. The supervisor now wants to connect to the PLC from the Engineering Workstation. How can you allow access from the Engineering Workstation to the PLC? (Choose one answer)
Answer: D
Explanation:
The correct answer is D. You must configure a layer 3 switch .
The study guide explains that "Layer 2 devices can add or remove tags" but "cannot modify them." It then states that "A layer 3 device, such as a router or FortiGate, can modify the VLAN tag before routing the packet. This allows them to route traffic between VLANs." It also explicitly describes
"Router on a Stick" as "a way to allow routing between VLANs." Since the exhibit shows a layer-2 switch and the Engineering Workstation and PLC are placed in different VLANs, inter-VLAN communication requires layer-3 routing.
The other options do not solve this requirement. intra-switch-policy explicit/implicit applies to a software switch , where member interfaces are in the same broadcast domain and same subnet, not to routing between separate VLANs. forward domain IDs are used in transparent mode to confine broadcasts to specific broadcast domains; they do not provide inter-VLAN access. Therefore, to let the Engineering Workstation in one VLAN reach the PLC in another VLAN, you need a layer 3 routing function , which matches option D .
