NEW QUESTION # 21
Which is the implementation of PROFIBUS over Ethernet for non-safety-related communications?
Available Choices (select all choices that are correct)

A. PROFIBUS PA
B. PROFIBUS DP
C. PROFINET
D. PROF1SAFE

Answer: C

Explanation:
PROFINET is the implementation of PROFIBUS over Ethernet for non-safety-related communications. It is a standard for industrial Ethernet that enables real-time data exchange between automation devices, controllers, and higher-level systems. PROFINET uses standard Ethernet hardware and software, but adds a thin software layer that allows deterministic and fast communication. PROFINET supports different communication profiles for different applications, such as motion control, process automation, and functional safety. PROFINET is compatible with PROFIBUS, and allows seamless integration of existing PROFIBUS devices and networks123 References: 1: What is PROFINET? - PI North America 2: PROFINET - Wikipedia 3: PROFINET Technology and Application - System Description

NEW QUESTION # 22
What are the three main components of the ISASecure Integrated Threat Analysis (ITA) Program?
Available Choices (select all choices that are correct)

A. Software robustness security testing, functional software assessment assurance, and essential security functionality assessment
B. Communication speed, disaster recovery, and essential security functionality assessment
C. Software development security assurance, functional security assessment, and communications robustness testing
D. Communications robustness testing, functional security assurance, and software robustness communications

Answer: C

Explanation:
The ISASecure Integrated Threat Analysis (ITA) Program is a certification scheme that certifies off-the-shelf automation and control systems to the ISA/IEC 62443 series of standards1. The ITA Program consists of three main components2:
* Software Development Security Assurance (SDSA): This component evaluates the security lifecycle and practices of the product supplier, such as security requirements, design, implementation, verification, and maintenance. The SDSA certification is based on the ISA/IEC 62443-4-1 standard.
* Functional Security Assessment (FSA): This component verifies the security functions and features implemented in the product, such as identification and authentication, access control, encryption, audit logging, and security management. The FSA certification is based on the ISA/IEC 62443-4-2 standard.
* Communications Robustness Testing (CRT): This component tests the resilience of the product against network attacks, such as denial-of-service, fuzzing, spoofing, and replay. The CRT certification is based on the ISA/IEC 62443-4-2 and ISA/IEC 62443-3-3 standards .

NEW QUESTION # 24
What is the name of the protocol that implements serial Modbus over Ethernet?
Available Choices (select all choices that are correct)

A. MODBUS/Plus
B. MODBUS/TCP
C. MODBUS/Ethernet
D. MODBUS/CIP

Answer: B

Explanation:
MODBUS/TCP is the name of the protocol that implements serial Modbus over Ethernet. MODBUS/TCP is a variant of the Modbus protocol that uses the Transmission Control Protocol (TCP) as the transport layer to encapsulate Modbus messages and send them over Ethernet networks. MODBUS/TCP preserves the Modbus application layer and data model, which means that serial Modbus devices can communicate with MODBUS/TCP devices through a gateway or a converter. MODBUS/TCP is widely used in industrial automation and control systems, as it offers high performance, interoperability, and compatibility with existing Modbus devices.
