NEW QUESTION # 33
Which industrial protocol does not support VLANs? (Choose one answer)
Answer: A
Explanation:
The correct answer is C. EtherCAT .
The study guide states that for industrial Ethernet protocols, "such as Ethernet/IP and Modbus/TCP, you can use VLANs to segment your physical LAN into multiple logical LANs." This directly confirms that Ethernet/IP and Modbus/TCP support VLAN-based segmentation in the OT context.
By contrast, the guide explains that "EtherCAT skips layers 3 to 6 to deliver real-time communication" and describes it as an "Open-Software Modified-Ethernet" approach. Because it does not operate like the standard Ethernet/IP model used for normal VLAN-based segmentation, EtherCAT is the protocol identified here as not supporting VLANs in the way Ethernet/IP and Modbus/TCP do.
So, based on the study guide comparison, the verified answer is EtherCAT .
NEW QUESTION # 34
Refer to the exhibit. A partial OT network is shown. You must improve the security of this OT network and implement internal segmentation between network 1 and network 2. How can you achieve the segmentation?
(Choose one answer)
Answer: D
Explanation:
The correct answer is D. You can configure forward domain IDs for each network . The study guide explains that in FortiGate transparent mode, "all interfaces belong to the same broadcast domain, even interfaces with different VLAN IDs" and then states that you should "use this command to subdivide into multiple broadcast domains" with set forward-domain < domain_ID > . It further explains that
"interfaces with the same domain ID belong to the same broadcast domain" and "traffic arriving on one interface is broadcast only to interfaces in the same forward domain ID." This is exactly the mechanism used to separate one internal network from another and improve segmentation.
The other options do not match this requirement. Universal ZTNA is described as controlling user access to applications , not segmenting two internal OT networks. An explicit software switch is for controlling intra- switch or intra-VLAN traffic inside the same software switch broadcast domain, which is more aligned with microsegmentation than separating two routed internal networks. One traffic VDOM does not create segmentation by itself; segmentation with VDOMs requires multiple VDOMs, not one. Therefore, the best choice for segmenting network 1 and network 2 in this scenario is to assign separate forward domain IDs .
NEW QUESTION # 35
Refer to the exhibit.
Which statement about this partial Asset Identity List page is correct? (Choose one answer)
Answer: A
Explanation:
Based on the OT Security 7.6 Architect study guide regarding the Asset Identity Center and Asset Management :
* Vulnerability Visibility : The Asset Identity List tab displays key metadata for IT and OT devices, including detected addresses, users, and a specific column for Vulnerabilities .
* Virtual Patching Feature : In the OT Security 7.6 architecture, the " Vulnerabilities " column is populated through the OT Security Service license, which includes " OT vulnerability correlation definitions & virtual patching signatures " .
* Correlation Mechanism : FortiGate extracts metadata from OT traffic and uses these signatures to identify known vulnerabilities on the assets. For these vulnerabilities to be identified and correlated in the Asset Identity Center as shown in the exhibit (displaying a count of 8 vulnerabilities), the Virtual Patching feature must be active.
* Architectural Implementation : Virtual patching is a critical component of the " Protection " layer in OT networks, allowing administrators to secure legacy or unpatchable PLCs and RTUs by blocking exploit attempts at the network level using IPS-based virtual patching signatures.
* Exhibit Analysis : The presence of identified vulnerabilities (the number " 8 " in the red shield) in the Asset Identity List confirms that the FortiGate is actively performing vulnerability correlation, which is the operational result of having a Virtual Patching security profile applied to the relevant firewall policy.
NEW QUESTION # 36
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: A
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.
