MANETs are:
- A.
  
  Infrastructure oriented
- B.
  
  Infrastructure less
- C.
  
  Partially infrastructure oriented d
- D.
  
  Partially infrastructure less
Correct Answer
B. Infrastructure less

Explanation
MANETs, or Mobile Ad hoc Networks, are networks that do not rely on any pre-existing infrastructure such as routers or access points. Instead, the nodes in a MANET communicate directly with each other, forming a temporary network on the fly. This makes MANETs highly flexible and suitable for scenarios where a fixed infrastructure is not available or practical, such as in disaster-stricken areas or military operations. Therefore, the correct answer is "Infrastructure less."

M2M stands for:
- A.
  
  MAC to MAC communication
- B.
  
  Machine to MAC communication
- C.
  
  Machine to machine communication
- D.
  
  MAC to machine communication
Correct Answer
C. Machine to machine communication

Explanation
M2M stands for Machine to machine communication. This refers to the direct communication between two or more devices without the need for human interaction. It involves the exchange of data and information between machines, allowing them to interact and collaborate autonomously. This technology is commonly used in various industries such as healthcare, transportation, and manufacturing, enabling efficient and automated processes.

With respect to WSN coverage problems, the OGDC algorithm is an acronym for:
- A.
  
  Optimal Geographic Density Control
- B.
  
  Optimal Geographic Distance Control
- C.
  
  Optimal Geographic Distance Coverage
- D.
  
  Optimal geographic Density Coverage
Correct Answer
A. Optimal Geographic Density Control

Explanation
The correct answer is "Optimal Geographic Density Control". This algorithm aims to optimize the geographic density of coverage in wireless sensor networks. It focuses on controlling the density of sensors in different areas to ensure efficient coverage and maximize network performance. By strategically adjusting the placement of sensors based on the density requirements, the algorithm can achieve optimal coverage in the network.

For testing the performance of the ad-hoc network, most accurate approach is
- A.
  
  Simulated
- B.
  
  Analytics
- C.
  
  Test Bed
- D.
  
  None of these
Correct Answer
C. Test Bed

Explanation
A test bed is the most accurate approach for testing the performance of an ad-hoc network. A test bed refers to a real-world environment that simulates the conditions in which the network will operate. This allows for accurate testing and evaluation of the network's performance in a controlled setting. Simulated approaches may not accurately represent real-world conditions, while analytics alone may not provide a comprehensive assessment. Therefore, a test bed provides the most accurate and reliable results for evaluating the performance of an ad-hoc network.

Terms piconet and scatternet are associated with
- A.
  
  Wi fi
- B.
  
  Zig bee
- C.
  
  Bluetooth
- D.
  
  LAN
Correct Answer
C. Bluetooth

Explanation
The terms piconet and scatternet are associated with Bluetooth. A piconet is a network formed by Bluetooth devices, where one device acts as the master and the others act as slaves. A scatternet is a network formed by multiple piconets, allowing communication between devices in different piconets. Wi-Fi is a wireless networking technology used for local area networking (LAN), while Zigbee is a low-power wireless communication technology used for short-range applications.

A crossing with respect to WSN is _______ if it is in the interior region of at least one node’s coverage disk
- A.
  
  Covered
- B.
  
  Partially covered
- C.
  
  Not covered
- D.
  
  Isolated
Correct Answer
A. Covered

Explanation
A crossing with respect to WSN is considered "covered" if it is located within the range of at least one node's coverage disk. This means that there is at least one node in the network that can detect and communicate with the crossing.

Internet of Things (IoT) can be integrated with which of these separate domains:
- A.
  
  Cloud-based storage and computing
- B.
  
  Cyber Physical Systems.
- C.
  
  Big-data networks.
- D.
  
  All of these
Correct Answer
D. All of these

Explanation
The Internet of Things (IoT) can be integrated with all of these separate domains. IoT can be connected to cloud-based storage and computing to store and process the vast amounts of data generated by IoT devices. It can also be integrated with cyber-physical systems, which are systems that combine physical components with computer-based control and monitoring systems. Additionally, IoT can be connected to big-data networks to analyze and utilize the large volumes of data collected by IoT devices. Therefore, all of these domains can be integrated with IoT.

IPv6 address consists of
- A.
  
  64 bits
- B.
  
  24 bits
- C.
  
  16 bits
- D.
  
  128 bits
Correct Answer
D. 128 bits

Explanation
IPv6 addresses consist of 128 bits. This is a key feature of IPv6, as it provides a much larger address space compared to IPv4, which only uses 32 bits. The increased number of bits allows for a significantly larger number of unique addresses, which is essential for the continued growth of the internet and the increasing number of devices connected to it. With 128 bits, IPv6 is capable of accommodating approximately 3.4 x 10^38 unique addresses, ensuring that there will be enough addresses for the foreseeable future.

Self-CHOP property of MANETs signify
- A.
  
  Configure, Heal, Optimize, Protect
- B.
  
  Communicate, Heal, Optimize, Protect
- C.
  
  Configure, Heal, Organize, Protect
- D.
  
  Communicate, Heal, Organize, Protect
Correct Answer
A. Configure, Heal, Optimize, Protect

Explanation
The correct answer is "Configure, Heal, Optimize, Protect". The self-CHOP property of MANETs signifies that the network is able to configure itself by automatically setting up connections and addressing, heal itself by adapting to changes and recovering from failures, optimize its performance by efficiently utilizing its resources, and protect itself from various security threats. This property ensures that the network is self-sustaining and can operate effectively in dynamic and unpredictable environments.

MANETS support following topolgy
- A.
  
  Star Topolgy
- B.
  
  Mesh Toplogy
- C.
  
  Ring Toplogy
- D.
  
  Not Fixed Toplogy
Correct Answer
D. Not Fixed Toplogy

Explanation
MANETs (Mobile Ad hoc Networks) do not support a fixed topology. Unlike traditional wired networks, MANETs are dynamic and have a constantly changing network topology due to the mobility of the nodes. The nodes in a MANET can move freely, join or leave the network at any time, and establish connections with other nodes in a spontaneous manner. Therefore, the network topology in MANETs is not fixed and can vary dynamically based on the movement and interactions of the nodes.
