NEW QUESTION # 220
According to the scheme for cybersecurity profiles, which of the following is true about ISA/IEC 62443 security requirements when creating a security profile?
Answer: A
Explanation:
ISA/IEC TR 62443-1-5 describes how to create cybersecurity profiles tailored to specific sectors or applications. While the core structure of security requirements remains, modifications are allowed to align with sector-specific needs or regulatory requirements.
"Profiles can tailor existing security requirements to better fit sector-specific needs. Modification of requirement wording, priority, or applicability may be made in line with risk tolerance and context."
- ISA/IEC TR 62443-1-5:2018, Clause 5.3 - Profile Customization
This enables flexibility while retaining consistency across profiles.

NEW QUESTION # 222
Which communications system covers a large geographic area?
Available Choices (select all choices that are correct)
Answer: D
Explanation:
A Wide Area Network (WAN) is a communications system that covers a large geographic area, such as a city, a country, or even several countries or continents1. WANs are often used to connect local area networks (LANs) and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations2. WANs use various communication infrastructures, such as public telephone lines, undersea cables, and communication satellites, to transmit data over long distances1. WANs are typically established with leased telecommunication circuits or less costly circuit switching or packet switching methods2. WANs are often built by Internet service providers, who provide connections from an organization's LAN to the Internet2. The Internet itself may be considered a WAN2.

NEW QUESTION # 223
What change was introduced in the second edition (2024) of ISA-62443-2-1 compared to the first edition (2010)?
Answer: A
Explanation:
The 2024 Second Edition of ISA/IEC 62443-2-1 was restructured to eliminate redundancy with ISO/IEC
27001 and to focus on aspects unique to IACS environments.
From ISA/IEC 62443-2-1:2024 Preface:
"The second edition removes duplication with ISO/IEC 27001 and instead focuses on IACS-specific considerations that complement an organization's overall ISMS." It still aligns with the Plan-Do-Check-Act (PDCA) model but no new framework was introduced - rather, clarity and applicability were improved.
Incorrect Options:
A). The PDCA model was retained, not newly introduced.
C). Supply chain security was actually emphasized, not removed.
D). The focus remains on system-wide security management, not just components.
