Refer to the exhibits.
A partial Incident Analysis page and the log details related to the event are shown. An attack is reported on your OT network. You analyze the corresponding incident. Based on the information provided on the Incident Analysis page and the log details, which two statements are correct? (Choose two answers)
Antwort: C,E
Begründung:
Based on the technical data provided in the exhibits and the OT Security 7.6 Architect curriculum:
* Industrial Protocol Identification (Statement A) : The log details exhibit clearly shows that the Destination Port used in the attack is 502 . According to the study guide ' s section on Industrial Protocol Protection , the standard port used by the Modbus TCP protocol is 502 . Furthermore, the attack name identifies a " Triangle.Research.Nano-10.PLC, " which are industrial controllers commonly utilizing Modbus for communications.
* Attack Mitigation (Statement B) : The log details specify that the Action taken by the FortiGate (Edge-FortiGate) was dropped . In cybersecurity and Fortinet fabric operations, dropping a packet associated with an IPS signature means the traffic was blocked from reaching its target, thereby mitigating the attack.
* Target IP Address (Statement E) : The log detail explicitly lists the Destination IP as 192.168.2.3 .
The Incident Analysis page also titles the incident with dstip:192.168.2.3. While the " Affected Endpoint " is shown as 10.1.5.20 , in an " outgoing " attack direction (as shown in the log), this likely refers to the internal source/attacker IP, whereas the target is the destination IP (192.168.2.3). Thus, Statement E is incorrect.
* Protocol Conflict (Statement C) : The IEC 104 protocol typically utilizes port 2404 . Since the log specifies port 502, Statement C is incorrect.
* Severity Distinction (Statement D) : While the Incident severity is marked as High , the question specifically asks about event severity. The " Events " table at the bottom of the Incident Analysis page shows a " User login/logout failed " event with a medium severity. Because there is a distinction in the management console between the severity of individual events and the aggregated incident, and Statement A and B are technically definitive based on port and action, A and B are the correct architectural choices.

Refer to the exhibit.
A Virtual Patching profile is shown. You have recently updated your SCADA system and would like to apply the SCADA virtual patching profile. Which two statements about this profile are correct? (Choose two answers)
Antwort: A,B
Begründung:
The correct answers are B and D .
Option B is correct because the profile has Medium , High , and Critical selected, while Low severity is not selected. That means low-severity virtual patching signatures are not enforced by this profile. So for the device with MAC address 12:12:12:12:12 , low-severity signatures are not blocked. The study guide explains virtual patching as device-specific protection where "FortiGate caches the signatures and mitigation rules that apply to each device" and applies them when the related traffic matches the firewall policy.
Option D is correct because the Virtual Patching Exemptions table shows a row with the MAC address 11:
11:11:11:11 and no specific signature listed. The study guide states that in the Virtual Patching profile you can "Exempt a specific device with the MAC address or a specific signature." A MAC-only exemption means that specific device is excluded from virtual patching enforcement, so in practical terms it is treated as having no applicable vulnerabilities in this profile.
Option C is incorrect because the profile does not block critical signatures for all devices. The exemptions list proves that at least one device can be excluded by MAC address, and a specific signature can also be exempted. Therefore, enforcement is not universal across all devices.
Option A is incorrect because the entry Schneider.Electric.ClearSCADA.HTTP.Interface.XSS appears as a specific signature exemption , not as the only remaining vulnerability. The profile display is showing exemptions, not a statement that only one vulnerability is still present.
49. Frage
Refer to the exhibit.
A partial OT network is shown. You want to provide the supervisor with secure remote access. Which two features can you implement on Edge-FortiGate ? (Choose two answers)
Antwort: A,B
Begründung:
Based on the exhibit and the OT Security 7.6 Architect standards for Secure Remote Access :
* Secure Tunneling (Statement A) : The exhibit shows a Remote PC connecting through a VPN Cloud to the Edge-FortiGate . In the Fortinet architecture, IPsec VPN is the primary method for establishing a secure, encrypted tunnel for remote administrators or supervisors to access the internal OT segments (Level 2/3) from an external location.
* Multi-Factor Authentication (Statement B) : Secure remote access in OT environments (aligned with IEC 62443 standards) requires strong authentication. The study guide emphasizes the use of FortiToken to provide Two-Factor Authentication (2FA) for VPN users, ensuring that compromised credentials alone are not enough to gain access to critical infrastructure.
* FSSO (Statement D) : Fortinet Single Sign-On is generally used for identifying internal users already on the network to apply identity-based policies; it is not the primary mechanism for establishing the remote connection itself.
* SD-WAN (Statement C) : While SD-WAN can manage the path of the VPN traffic, it is a WAN optimization and reliability feature, not a " secure remote access " feature for a supervisor in the context of authentication and encryption.
50. Frage
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)
Antwort: C,D
Begründung:
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 .
51. Frage
Refer to the exhibit.
The configuration of firewall policies is shown.
To improve the security of your OT network, you have configured authentication in the firewall policies as shown in the exhibit, with CLI parameters set to their default settings. However, when you test HTTPS access from the LAN subnet to PLC-1, it is successful without any authentication prompt.
What is the reason?
Antwort: D
Begründung:
The correct answer is A . Policy ID 8 contains the Supervisors user group, so authentication is required for traffic matching that policy. However, policy ID 9 permits traffic to PLC-1 without a user or user-group authentication requirement. Fortinet explains that when an authentication policy is followed by a fall-through policy that does not require authentication , traffic can match the fall-through policy and proceed without generating a login prompt. This is particularly relevant because the default CLI setting is auth-on-demand implicitly. Under the default implicitly behavior, FortiGate does not trigger active authentication when a matching unauthenticated fall-through policy exists. Setting auth-on-demand always, or requiring authentication on all potentially matching policies, changes that behavior. Therefore, HTTPS succeeds without prompting because authentication was not configured on firewall policy ID 9 .
