ISA/IEC 62443 Cybersecurity Fundamentals Specialist Sample Questions (Q56-Q61):

NEW QUESTION # 56
In which layer is the physical address assigned?
Available Choices (select all choices that are correct)

  • A. Layer 1
  • B. Layer 2
  • C. Layer 7
  • D. Layer 3

Answer: B

Explanation:
According to the OSI model, the physical address is assigned in the layer 2, also known as the data link layer.
The physical address is a unique identifier for each device on a network, such as a MAC address or a serial number. The data link layer is responsible for transferring data between adjacent nodes on a network, using the physical address to identify the source and destination of each frame. The data link layer also provides error detection and correction, flow control, and media access control.

NEW QUESTION # 57
Which of the following is the underlying protocol for Ethernet/IP?
Available Choices (select all choices that are correct)

  • A. Common Industrial Protocol
  • B. Building Automation and Control Network (BACnet)
  • C. Object Linking and Embedding (OLE) for Process Control
  • D. Highway Addressable Remote Transducer (HART)

Answer: A

Explanation:
Ethernet/IP is an industrial network protocol that adapts the Common Industrial Protocol (CIP) to standard Ethernet. CIP is an object-oriented protocol that provides a unified communication architecture for various industrial automation applications, such as control, safety, security, energy, synchronization and motion, information and network management. CIP defines a set of messages and services for interacting with devices and data on the network, as well as a set of device profiles for consistent implementation of automation functions across different products. Ethernet/IP uses the transport and control protocols of standard Ethernet, such as TCP/IP and IEEE 802.3, to define the features and functions for its lower layers. Ethernet/IP also uses UDP to transport I/O messages and supports various network topologies, such as star, linear, ring and wireless.
Ethernet/IP is one of the leading industrial protocols in the United States and is widely used in a range of industries, such as factory, hybrid and process. Ethernet/IP is managed by ODVA, Inc., a global trade and standards development organization. References:

What is defined as the hardware and software components of an IACS?
Available Choices (select all choices that are correct)

  • A. Electronic security
  • B. COTS software and hardware
  • C. Cybersecuritv
  • D. Control system

Answer: D

Explanation:
According to the ISA/IEC 62443-1-1 standard, an industrial automation and control system (IACS) is defined as a collection of personnel, hardware, and software that can affect or influence the safe, secure, and reliable operation of an industrial process. The hardware and software components of an IACS include the control system, which is the combination of control devices, networks, and applications that perform the control functions for the industrial process. The control system may consist of various types of devices, such as distributed control systems (DCS), programmable logic controllers (PLC), supervisory control and data acquisition (SCADA) systems, human-machine interfaces (HMI), remote terminal units (RTU), intelligent electronic devices (IED), sensors, actuators, and other field devices. The control system may also use commercial off-the-shelf (COTS) software and hardware, such as operating systems, databases, firewalls, routers, switches, and servers, to support the control functions and communication.
