Machine to Machine is______________________Technology and IoT is_____________________Technology
Correct Answer
B. Hardware Based, Software Based
Explanation
The correct answer is Hardware Based, Software Based. Machine to Machine (M2M) technology refers to the communication between two or more machines without human intervention, which is typically accomplished through hardware components. On the other hand, IoT (Internet of Things) technology is a combination of hardware and software that allows objects to connect and exchange data over the internet. Therefore, both M2M and IoT technologies involve hardware and software components for their operation.
5.
Which among the following is true?
Correct Answer
C. M2M is a subset of IoT
Explanation
The correct answer is M2M is a subset of IoT. This means that Machine-to-Machine (M2M) communication is a part of the broader concept of Internet of Things (IoT). M2M refers to the direct communication between devices without human intervention, while IoT encompasses a wider range of interconnected devices and systems that collect and exchange data. Therefore, M2M is a subset of IoT because it represents a specific type of communication within the larger IoT framework.
6.
Which of the following is not a feature of M2M?
Correct Answer
C. Intelligence
Explanation
The feature of M2M that is not mentioned in the options is "Intelligence". M2M (Machine-to-Machine) communication refers to the direct communication between devices without human intervention. It typically involves transmitting data or commands between machines. While M2M systems can be designed to be intelligent and capable of making decisions, it is not a fundamental feature of M2M communication. The other options, such as Time Telerancy, Low Mobility, and Packet Switched, are all features that can be associated with M2M communication.

Therefore, M2M Applications play a crucial role in the analysis of data in the M2M ecosystem.
8.
In which type of network, network management is difficult.
Correct Answer
B. Traditional Network
Explanation
In a traditional network, network management is difficult because it involves manual configuration and management of each network device individually. This can be time-consuming and prone to errors. Additionally, traditional networks often lack centralized control and visibility, making it challenging to monitor and troubleshoot network issues. On the other hand, SDN (Software-Defined Networking) offers centralized control and programmability, making network management more efficient and flexible. Therefore, the correct answer is Traditional Network.
9.
Which plane helps SDN to make network management easier?
Correct Answer
B. Controller Plane
Explanation
The correct answer is the Controller Plane. In Software-Defined Networking (SDN), the Controller Plane is responsible for managing and controlling the network. It acts as the brain of the network, making decisions and implementing policies to direct the flow of data. By centralizing the network management functions, the Controller Plane simplifies network management and allows for more efficient control and configuration of the network. Additionally, it enables automation and programmability, making it easier to adapt and scale the network according to changing requirements.
10.
For monitoring room temperature which level of IoT is to be used?
Correct Answer
D. Level 1

Explanation
IoT Protocols ensure that information from one device gets read and understood by another device. These protocols define a set of rules and standards that enable devices to communicate and exchange data effectively. By using IoT protocols, devices can establish a common language and format for transmitting information, ensuring compatibility and interoperability between different devices and systems in the IoT ecosystem.
16.
Publish command message to publish information on a specified topic or topics is sent from _________
Correct Answer
C. Both Publisher to broker and broker to publisher
Explanation
The correct answer is "Both Publisher to broker and broker to publisher." In the publish-subscribe messaging pattern, the publisher sends a publish command message to the broker to publish information on a specified topic or topics. The broker then forwards this information to the subscribed clients. Additionally, the broker can also send messages to the publisher, such as acknowledgments or requests for more information. Therefore, communication occurs in both directions between the publisher and the broker.
17.
Which system refers to an abstract representation of the entities & processes without going into the low-level specifics of the implementation?
Correct Answer
B. Logical Design of IoT
Explanation
Logical Design of IoT refers to an abstract representation of the entities and processes involved in the Internet of Things without delving into the specific implementation details. It focuses on the overall structure, relationships, and functionality of the IoT system, providing a high-level view that helps in understanding and designing the system without getting into the nitty-gritty of how it is physically implemented.

19.
………. Is based on HTTP which is stateless protocol.
Correct Answer
A. REST
Explanation
REST is based on HTTP, which is a stateless protocol. This means that each request from the client to the server is independent and does not rely on any previous requests or stored state. RESTful APIs use HTTP methods like GET, POST, PUT, and DELETE to perform operations on resources. This statelessness allows for scalability, simplicity, and ease of caching, making REST a popular choice for building web services. Web Sockets, on the other hand, are a communication protocol that allows for real-time, bidirectional communication between the client and server, but they are not based on HTTP and are not stateless. Therefore, the correct answer is REST.
20.
Which of the following is/are the Functions of IoT?
Correct Answer
D. All the above
Explanation
The correct answer is "All the above" because IoT (Internet of Things) involves the use of sensors to sense and collect data from the environment, actuating devices to perform certain actions based on the collected data, and monitoring the entire system to ensure proper functioning and performance. Therefore, all three functions (sensing, actuating, and monitoring) are essential components of IoT.
