質問 # 53
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 # 54
Refer to the exhibit.
Which statement about this partial Asset Identity List page is correct? (Choose one answer)
正解：A
解説：
The correct answer is B. A firewall policy has a Virtual Patching security profile applied to it .
The decisive clue in the exhibit is the Vulnerabilities column showing KEVs and device-specific vulnerability counts. The study guide explains the virtual patching workflow in this exact way: "FortiGate performs a lookup for device-specific vulnerabilities and mitigation rules in FortiGuard," then
"FortiGuard returns specific OT virtual patching signatures," and "FortiGate caches the signatures and mitigation rules that apply to each device." That is the same behavior reflected by the Asset Identity List showing vulnerability information per detected device.
The guide then states that "When traffic related to the vulnerable device reaches FortiGate, the firewall policy with the virtual patching profile applies." It also says "A virtual patching profile can be applied to firewall policies in any direction, protecting traffic from or to the vulnerable OT device." This directly links the per-device vulnerability visibility to a Virtual Patching profile enforced through firewall policy.
The other options do not match the exhibit. Antivirus is not described in the study guide as building a device- by-device vulnerability list, Application Control is used for OT protocol and message visibility, and IPS focuses on exploit detection and prevention. The Vulnerabilities/KEVs display is the indicator that FortiGate is using Virtual Patching logic for those OT devices.
質問 # 55
How are rogue devices evaluated in FortiNAC? (Choose one answer)
正解：B
解説：
The correct answer is A. Through device profiling rules . The study guide states: "When a rogue device record is created, the device is evaluated against the enabled device profiling rules." It further explains that "FortiNAC evaluates a device against each rule until a failed, passed, or cannot evaluate result is reached." That is the direct evaluation mechanism used for rogue devices in FortiNAC.
The guide also adds that "Device profiling rules are used to evaluate and classify rogue devices" and that FortiNAC applies rule methods and classification settings to determine whether the device matches a known type. This is why the other options are incorrect: FortiGuard server queries and the local device database (CIDB) relate to FortiGate device detection workflows, not FortiNAC rogue-device evaluation, and importing a devices list is not the evaluation method described for rogue devices.
質問 # 56
Refer to the exhibit.
A basic event handler is shown. You have enabled Automation Stitch to automate the handling of an alert.
Which two steps must you take to use this automation stitch? (Choose two answers)
正解：C、D
解説：
The correct answers are C and D .
Option D is correct because the study guide states that the configuration of an event handler can include
"Rules" and explains that "Rules are granular conditions" and "Event handlers can have one or more rules." It further states that "FortiAnalyzer uses event handlers to filter all incoming logs" and "If logs match the conditions configured in an event handler, FortiAnalyzer generates an event." Therefore, to use the automation stitch, you must define the rules on FortiAnalyzer so the event handler can actually generate the event that starts the automation flow.
Option C is also correct. The study guide explains that "When a handler generates an event with the automation stitch option enabled, FortiAnalyzer sends a notification" to the FortiGate side, and in the attack-detection example it says "FortiAnalyzer parses the logs and notifies the root FortiGate" and then
"The root FortiGate triggers the action." It also explicitly shows "Stitches configured on root FortiGate." This means the FortiGate must have the corresponding automation trigger configured for the FortiAnalyzer event handler notification.
Option A is incorrect because the study guide does not describe configuring an Action on FortiAnalyzer as the required step for this FortiAnalyzer-to-FortiGate automation-stitch flow. Option B is also incorrect because playbooks are a different FortiAnalyzer automation mechanism; the question specifically refers to using the Automation Stitch option in the event handler.
質問 # 57
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：A
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 .
