Certainly, here are the reasons for each answer along with the respective questions:
1. **What are some of the other names of the smart grids?**
- Answer: d. All of these
- Reason: Smart grids are known by various names, including "Electricity with a brain," "Energy internet," and "Electronet," among others.
2. **Smart Grid follows which type of the flow of energy?**
- Answer: a. Bidirectional
- Reason: Smart grids allow for bidirectional flow of energy, meaning electricity can flow not only from the power station to consumers but also from consumers (e.g., solar panels) back into the grid.
3. **Which of the following is not a benefit associated with smart grids?**
- Answer: c. Unreliable and insecure electricity
- Reason: Smart grids aim to improve the reliability and security of electricity, so "Unreliable and insecure electricity" is not a benefit but a problem they seek to address.
4. **Which of the following is a component of smart grid communication?**
- Answer: d. All of these
- Reason: Smart grid communication involves various components, including gateways, smart meters, and MDMSs (Meter Data Management Systems), all of which play essential roles in the communication infrastructure.
5. **Fill in the blank. ___________ can be used as an energy source in on-peak hours.**
- Answer: c. PEVs (Plug-in Electric Vehicles)
- Reason: Plug-in Electric Vehicles (PEVs) can be used as an energy source during on-peak hours when their batteries can discharge power back into the grid.
6. **Which of the following is a type of Dynamic System Attacks?**
- Answer: d. All of these
- Reason: Dynamic System Attacks encompass various attack types, including Replay Attacks, Dynamic data injection attacks, and Covert attacks.
7. **Which of the following statements are true about gateways?**
- Answer: b. Statements I and III
- Reason: Gateways connect closely located smart meters (Statement I) and facilitate two-way communication (Statement III). However, they may not necessarily communicate mostly based on WiFi (Statement II).
8. **Fill in the blank. ____________ is a centralized coordinator for smart grid communication.**
- Answer: d. MDMS (Meter Data Management System)
- Reason: The MDMS serves as a centralized coordinator for managing and processing data from smart meters and other devices in the smart grid.
9. **Fill in the blank. ____________ are available protocols for smart home appliances.**
- Answer: d. All of these
- Reason: Various protocols, including C-Bus, DECT, and EnOcean, are available for smart home appliances to communicate with each other and with the smart grid.
10. **Fill in the blank. IIoT is a network of____________.**
- Answer: d. All of the above
- Reason: The Industrial Internet of Things (IIoT) is a network that includes physical objects, systems, and platforms, making "All of the above" the correct answer.
11. **IIoT is based on Rip & Replace approach.**
- Answer: b. False
- Reason: IIoT typically doesn't require a Rip & Replace approach. It is designed to integrate with existing systems and equipment, minimizing the need for a complete overhaul.
12. **Which of the following happened in the 1st Revolution?**
- Answer: a. Mass production
- Reason: The 1st Industrial Revolution was characterized by the transition to mass production, driven by innovations like the steam engine and mechanized textile production.
13. **Which of the following is a challenge of IIoT?**
- Answer: d. All of these
- Reason: IIoT poses challenges such as ensuring worker health and safety, addressing environmental concerns in production, and optimizing operations, making "All of these" the correct answer.
14. **Monitoring and restoration of the traditional electrical grid is done manually.**
- Answer: a. True
- Reason: In traditional electrical grids, monitoring and restoration often rely on manual processes. Smart grids aim to automate and improve these processes.
15. **What is Hadoop used in?**
- Answer: c. All of these
- Reason: Hadoop is a framework used for distributed processing of large datasets and can be implemented in large clusters of computers, making "All of these" the correct answer.
