NEW QUESTION # 10
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 # 11
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 # 12
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: A
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 .
NEW QUESTION # 13
As the first step in your OT network protection plan, you must identify the OT protocols that the FortiGate device supports. Which two configurations must you implement on this FortiGate device? (Choose two answers)
Answer: B,D
Explanation:
The correct answers are B and C . The study guide states that "You can use application control signatures to detect OT protocols" and that "Application control detects the protocols used in applications like Modbus, IEC 104, and the contents of the telecontrol messages" . It also shows that a Modbus application control profile can be enabled on a firewall policy "for OT protocol visibility in the monitor status." This directly supports B , because application control is the feature used to identify and monitor OT protocols on FortiGate.
The guide also explains under IPS that "By default, OT signatures are excluded from the signatures lists on the GUI until you enable them on the CLI" using config ips global and set exclude-signatures none .
Once enabled, FortiGate can use those OT signatures for OT-aware inspection and protection. That supports C as the second required configuration. A is related to device discovery, not protocol identification, and D is focused on exploit and vulnerability detection rather than the first-step goal of identifying OT protocols.
NEW QUESTION # 14
According to the IEC 62443 standard, your security level is 4 . What is your OT environment defending against? (Choose one answer)
Answer: A
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 " .
