NEW QUESTION # 25
Refer to the exhibit.
An industrial Ethernet protocol skipping layers 3 to 6 is shown. Which industrial Ethernet protocol is it?
(Choose one answer)
Answer: B
Explanation:
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 .
NEW QUESTION # 26
What is the next step if FortiGate cannot detect a device locally? (Choose one answer)
Answer: A
Explanation:
The correct answer is A. FortiGate queries FortiGuard servers . The study guide explains the device detection process very clearly: "First, FortiGate attempts to detect the devices based on the information in the local device database (CIDB). If FortiGate cannot detect the devices locally, it queries the FortiGuard servers by sending data about the unknown devices to the FortiGuard servers. In response, the FortiGuard servers provide additional information about those devices." This directly answers the question and shows that querying FortiGuard is the next step after local detection fails.
Option D is incorrect because the guide says FortiGate checks the local device database (CIDB) first, before this next step. Option B refers more to FortiNAC-style profiling logic, not FortiGate's OT device detection flow. Option C is also incorrect because service connectors are not described here as the immediate follow-up step for unknown local device detection. The study guide specifically identifies FortiGuard servers as the next destination for device identification assistance.
NEW QUESTION # 27
Which characteristic do the following industrial protocols share: Ethernet/IP, EtherCAT, and POWERLINK?
Answer: D
Explanation:
The correct answer is A . The study guide describes all three protocols as supporting deterministic or real-time industrial communication. Ethernet/IP uses standard Ethernet and TCP/IP with an application-layer mechanism that can provide real-time communication when deployed within an appropriate limited range.
EtherCAT explicitly provides real-time communication in a primary-secondary architecture and achieves its performance by skipping OSI layers 3 through 6. POWERLINK is also explicitly defined as a real-time communication protocol used mainly for transmitting process data. They do not all follow the complete OSI model because EtherCAT bypasses several layers and POWERLINK primarily uses layers 2 and 7. Client- server behavior is specifically associated with Modbus , and star/ring topology characteristics relate to redundancy mechanisms such as PRP, MRP, and HSR rather than these three industrial protocols collectively.
NEW QUESTION # 28
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)
Answer: A,B
Explanation:
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.
NEW QUESTION # 29
Refer to the exhibit.
Which statement about this partial Asset Identity List page is correct? (Choose one answer)
Answer: C
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.
