QUIZ 2 - PTI

Which of the following scenarios best represents the fundamental principle of the feedback loop in Cyber-Physical Systems (CPS)?

• A mapping drone that takes images periodically without considering changes in wind direction around it.

• An automatic irrigation system that opens water valves based only on a schedule without monitoring soil moisture levels.

• A cleaning robot that detects obstacles in front of it, calculates an alternative path, and automatically adjusts its movement.

• A security camera that records video 24/7 and stores the footage in a cloud server for later viewing.

What is the main meaning of the hierarchy and feedback loop diagram in Cyber-Physical Systems (CPS)?

• Information from the physical state is processed by cyber systems to generate actions that affect both the physical world and humans.

• Human interaction only occurs at the top level (system-of-systems).

• Devices are not directly involved in decision-making processes.

• CPS operates linearly without any feedback loop between physical and cyber domains.

Which of the following statements best explains why the five examples in the image are categorized as Cyber-Physical Systems (CPS)?

• These systems rely solely on initial programming and do not adapt to environmental conditions.

• The listed examples are purely AI-based systems that do not integrate with physical components.

• Each system is manually operated by a human user at all times using a user interface.

• All systems are capable of making autonomous decisions based on continuously updated sensor data and performing physical actions in real time.

What is the main function of Level I: Smart Connection in the architecture of Cyber-Physical Systems (CPS)?

• Automatically optimizing for disturbances in the system.

• Providing sensor networks and wireless communication to connect physical components.

• Predicting performance degradation through data analytics.

• Providing digital twin models for machine components.

What is the main role of the Internet of Things (IoT) based on the diagram showing its relation to CPS?

• Controlling actuators and making autonomous decisions.

• Combining computational decisions and executing advanced logic functions.

• Optimizing interaction between the physical world and manual human control systems.

• Generating data from sensors and transmitting it through communication networks.

Why are the Segway, Guided Missile, and Mars Rover considered CPS that are not IoT-based?

• Because they are self-contained systems that do not rely on external network connectivity.

• Because they use cloud computing to handle all processes.

• Because all of them require high-speed internet connections to function.

• Because they are wearable devices used directly by humans.

Why is security considered highly important in Cyber-Physical Systems (CPS)?

• Because CPS only operates in stable virtual environments.

• Because CPS systems are designed without considering physical interaction.

• Because a system failure in CPS can lead to serious consequences in the real world.

• Because CPS systems do not produce real-time data.

What does interoperability mean in the context of CPS according to the image?

• CPS can only operate with one specific type of hardware.

• CPS is designed to connect its components using open communication protocols.

• CPS should use closed systems for security purposes.

• Interoperability only relates to cost efficiency in CPS development.

Which of the following fields is not commonly involved in the development of Cyber-Physical Systems (CPS)?

• Computer architecture

• Embedded system design

• Software engineering

• Fine arts and graphic design

What happens when CPS takes into account the “system of systems” concept?

• The scope of CPS becomes broader.

• CPS becomes simpler to implement.

• CPS is only used for small-scale projects.

• CPS no longer requires formal verification.
