Which physical topology allows only one-way flow of data across the media?
Correct Answer
C. Ring
Explanation
A ring topology allows only one-way flow of data across the media. In a ring network, each device is connected to exactly two other devices, forming a closed loop. Data is transmitted in one direction around the ring, passing through each device until it reaches its destination. This ensures that data flows in a single direction, preventing collisions and ensuring efficient communication.
2.
Which of the following is NOT an advantage of deploying a network
Correct Answer
D. Initial cost is low
Explanation
The initial cost being low is not an advantage of deploying a network. Deploying a network typically involves purchasing hardware, software, and setting up infrastructure, which can incur significant upfront costs. However, the advantages of deploying a network include sharing hardware, software, and information, which can lead to cost savings and improved efficiency in the long run.

The network medium that requires light to transmit data is called...
Correct Answer
C. Fibre Optic
Explanation
Fibre optic is the correct answer because it is a network medium that uses light to transmit data. Unlike twisted pair and coaxial cable, which use electrical signals, fibre optic cables use pulses of light to carry information. This technology allows for faster data transmission and longer distances without signal degradation. Bluetooth, on the other hand, is a wireless communication technology that does not require a physical medium like fibre optic cables.
5.
One typical example of unguided transmission medium is......
Correct Answer
D. Bluetooth
Explanation
Bluetooth is an example of an unguided transmission medium because it uses wireless technology to transmit data. Unlike twisted pair, coaxial cable, and fiber optic, which rely on physical cables to transmit signals, Bluetooth uses radio waves to transmit data between devices. This makes Bluetooth a suitable choice for short-range communication between devices, such as connecting a smartphone to a wireless headset or transferring files between two laptops.
6.
.................. cover a limited geographical area such as an office.
Correct Answer
C. LAN
Explanation
A LAN (Local Area Network) is a type of computer network that is designed to cover a limited geographical area, such as an office or a building. It allows multiple devices, such as computers and printers, to be connected and share resources within the same area. Unlike a WAN (Wide Area Network) or MAN (Metropolitan Area Network), a LAN is typically smaller in scale and is privately owned and operated. Therefore, the given answer, LAN, is the correct choice as it accurately describes a network that covers a limited geographical area like an office.
7.
End nodes that have the functionality to receive and send information in a communication infrastructure are ........
Correct Answer
B. Transceiver
Explanation
A transceiver is a device that combines both the functionality of a transmitter and a receiver in a communication infrastructure. It is capable of both sending and receiving information, making it an end node that can actively participate in the communication process. This makes the transceiver an essential component in various communication systems, such as wireless networks, where it can both transmit data to other devices and receive data from them.
8.
LAN layout in which all nodes are individually connected to a central connection point, like a hub or a switch is ..................
Correct Answer
A. Star
Explanation
In a star LAN layout, all nodes are individually connected to a central connection point, such as a hub or a switch. This central point acts as a communication hub, allowing all nodes to communicate with each other. This layout is commonly used in Ethernet networks as it provides better performance and reliability compared to other layouts. Nodes can easily be added or removed without affecting the rest of the network, making it a flexible and scalable option.
9.
.................is it limited to only monetary transactions on the internet.
Correct Answer
B. E-commence
Explanation
The correct answer is "E-commence" because e-commerce refers to the buying and selling of goods and services over the internet, which includes both monetary transactions and non-monetary transactions such as online shopping, online banking, and online booking of services. Therefore, it is not limited to only monetary transactions on the internet.
10.
Which of the following is/ are the drawbacks of Ring Topology?
Correct Answer
D.
Both of A and B
Explanation
The correct answer is "Both of A and B". This means that both the failure of one computer affecting the whole network and the disturbance of network activity when adding or removing computers are drawbacks of Ring Topology. Additionally, if the central hub fails, the entire network fails to operate, which is another drawback of this topology.

Correct Answer
C. MAC Filtering
Explanation
MAC Filtering is a wireless network security implementation where the device cannot connect if its physical address is not added to the trusted list. This means that only devices with specific MAC addresses are allowed to connect to the network, providing an additional layer of security by preventing unauthorized access. SSID refers to the network name, WEP and WPA are encryption protocols used to secure wireless networks.
13.
The IEEE standard for wifi is.......
Correct Answer
B. 802.11
Explanation
The correct answer is 802.11. This is the IEEE standard for wireless local area networks (WLANs), commonly known as WiFi. It specifies the protocols and technologies used for wireless communication in the 2.4 GHz and 5 GHz frequency bands. This standard ensures compatibility and interoperability between different WiFi devices, allowing them to connect and communicate with each other seamlessly.
14.
................... is a computer network covering broad geographical areas such as state or country
Correct Answer
C. WAN
Explanation
A WAN (Wide Area Network) is a computer network that spans a large geographical area, typically covering a state or country. It connects multiple local area networks (LANs) and allows for the transmission of data and communication between different locations. Unlike LANs, which are limited to a small area such as an office or building, WANs provide connectivity over longer distances. Therefore, the correct answer is WAN.

The structure of telecommunication networks comprise of control plane, user plane and .........
Correct Answer
management plane, Management plane
Explanation
The structure of telecommunication networks consists of three main components: the control plane, the user plane, and the management plane. The control plane is responsible for establishing and maintaining connections between network devices, while the user plane is responsible for the actual transmission of data. The management plane, on the other hand, is responsible for the overall management and control of the network, including tasks such as configuration, monitoring, and troubleshooting. Therefore, the correct answer is the management plane, which plays a crucial role in ensuring the smooth operation and maintenance of telecommunication networks.
