NEW QUESTION # 117
If an asset owner wants to improve their organization's ability to respond during a cyberattack, which of the following activities would be MOST appropriate to implement?
Answer: A
Explanation:
Tabletop exercises simulate cybersecurity incidents in a non-disruptive setting, helping teams test and improve their incident response plans and communication protocols.
"Tabletop exercises allow personnel to rehearse roles, responsibilities, and actions in a simulated event scenario. This enhances coordination, preparedness, and decision-making during actual incidents."
- ISA/IEC 62443-2-1:2010, Clause 4.3.3.3 - Incident Response Preparedness They are essential for verifying that the incident handling process (SP Element 7) is both understood and effective.

NEW QUESTION # 118
What is a key feature of the NIS2 Directive?
Answer: C
Explanation:
The NIS2 Directive, an update to the European Union's cybersecurity directive, introduces several new requirements, including the establishment of a cyber crisis management framework at both national and EU levels. This is designed to coordinate effective responses to major cybersecurity incidents and crises. NIS2 goes beyond mandating compliance or focusing only on physical security and emphasizes collaboration between the public and private sectors.
Reference: NIS2 Directive (Directive (EU) 2022/2555), Articles 9-11, and official ENISA documentation.
NEW QUESTION # 119
What is OPC?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
OPC stands for Open Platform Communications, and it is a series of standards and specifications for industrial telecommunication based on Object Linking and Embedding (OLE) for process control. It allows the communication of real-time data between devices from different manufacturers using various data transportation technologies, such as Microsoft's OLE, COM, DCOM, .NET, XML, and TCP123. OPC is not a protocolitself, but rather a standardized approach for data connectivity supported by the OPC Foundation3. OPC is widely used in industrial automation and control systems, as well as other industries, to achieve interoperability and integration between different applications and devices3.
A is incorrect, because OPC is not a field bus protocol, but rather a standard for data exchange between devices that may use different field bus protocols, such as Modbus, Profibus, or Ethernet/IP2. C is incorrect, because OPC is not a serial communications protocol, but rather a standard that can use various data transportation technologies, including serial, Ethernet, or wireless2. D is incorrect, because OPC is not a vendor-specific proprietary protocol, but rather an open standard that can be implemented by any vendor or device that supports the OPC specifications3.

NEW QUESTION # 120
What should the identification analysis of discovered vulnerabilities determine?
Answer: C
Explanation:
In the context of vulnerability management within industrial systems, the identification analysis aims to determine the root cause of the vulnerability in order to understand its origin and impact, and to plan appropriate mitigation actions. This is a crucial step in the Secure Product Development Lifecycle (SDL) described in ISA/IEC 62443-4-1.
"The supplier shall perform vulnerability root cause analysis as part of the identification phase to determine the underlying cause of the vulnerability. This helps to guide the correction and prevention process."
- ISA/IEC 62443-4-1:2018, SR 6.2.1 - Vulnerability Identification and Handling This process not only addresses the specific issue but also improves the product development lifecycle by preventing similar future flaws.

NEW QUESTION # 121
After receiving an approved patch from the JACS vendor, what is BEST practice for the asset owner to follow?
Answer: B
Explanation:
According to the ISA/IEC 62443 Cybersecurity Fundamentals Specialist resources, patches are software updates that fix bugs, vulnerabilities, or improve performance of a system. Patches are classified into three categories based on their urgency and impact: low, medium, and high. Low priority patches are those that have minimal or no impact on the system functionality or security, and can be applied at the next scheduled maintenance. Medium priority patches are those that have moderate impact on the system functionality or security, and should be applied within a reasonable time frame, such as three months. High priority patches are those that have significant or critical impact on the system functionality or security, and should be applied as soon as possible, preferably at the first unscheduled outage. Applying patches in a timely manner is a best practice for maintaining the security and reliability of an industrial automation and control system (IACS).
