Hello students welcome to csestudy247.com
These Multiple choice question Based on the Network Topology
Q.1 Which of the following topologies are used in a LAN (Local Area Network)?
Star Topology
BUS Topology
Ring Topology
All of the above
Explanation
LANs can be implemented using various physical layouts, including Star, Bus, and Ring, depending on the requirements of the building or office.
Q.2 Which of the following topologies is commonly used in a MAN (Metropolitan Area Network)?
Star Topology
BUS Topology
Ring Topology
All of the above
Explanation
Ring topology (specifically dual rings like FDDI) is frequently used in city-wide networks for its redundancy and data handling capabilities.
Q.3 Which of the following topologies is often used to structure a WAN (Wide Area Network)?
Star Topology
Tree Topology
Ring Topology
All of the above
Explanation
Tree topology is often used in WANs because it allows for easy expansion and hierarchical management of large, distant network segments.
Q.4 Which of the following network topologies is currently the most widely used?
Star Topology
Tree Topology
Ring Topology
None of these
Explanation
Star topology is the most popular because it is easy to install, manage, and if one cable fails, only that specific node is affected.
Q.5 Which topology is most commonly implemented in environments like Colleges and Schools?
Star Topology
Tree Topology
Ring Topology
None of these
Explanation
Schools and colleges typically use Star topology where all computers in a lab connect to a central switch or hub.
Q.6 Which of the following topologies provides the fastest data transmission and highest reliability?
Star Topology
Mesh Topology
Ring Topology
None of these
Explanation
Mesh topology is the fastest and most reliable because every device has a dedicated point-to-point link to every other device, preventing traffic congestion.
Q.7 What is the formula to find the number of physical links required in a fully connected mesh network with 'n' nodes?
n(n-1)/2
n(n+1)/2
n(n-1)/3
None of these
Explanation
In a full mesh, the number of duplex links is calculated as n(n-1)/2, where n is the number of devices.
Q.8 The physical or logical arrangement of the nodes and connections in a network is called?
Topology
Network
Routing
None of these
Explanation
Network topology defines the layout, including the placement of nodes and the way the lines of communication are connected.
Q.9 In a Mesh topology, devices are connected via which type of link?
Point to point link
Single link
Multipoint link
None of these
Explanation
Mesh topology utilizes dedicated point-to-point links, meaning each cable carries data only between the two devices it connects.
Q.10 In a Star topology, all individual nodes are connected to a central device called a?
HUB
Repeater
Gateway
None of these
Explanation
The Hub (or Switch) acts as the central controller in a Star topology, managing all data traffic between the connected devices.
Q.11 In which topology are 'Terminators' used at both ends of the main transmission line?
Bus
Star
Ring
None of these
Explanation
Terminators are used in Bus topology to absorb signals at the ends of the cable, preventing signal reflection which causes data corruption.
Q.12 Which topology is considered the best choice for managing very large and complex networks?
Bus
Tree
Ring
None of these
Explanation
Tree topology (a combination of Star and Bus) is ideal for large networks as it allows for organized, hierarchical growth.
Q.13 In which topology does the failure of a single computer's network cable cause the entire network to go down?
Bus
Tree
Ring
None of these
Explanation
In a Bus topology, because all devices share a single backbone cable, a break anywhere in the main line disrupts the entire network.
Q.14 Which of the following can act as the central connecting device in a Star topology?
STP server
Hub
Switch
Both B & C
Explanation
Both Hubs and Switches serve as the central node in a Star configuration to facilitate communication between other devices.
Q.15 Which of the following is a network model rather than a physical network topology?
Star
Ring
Bus
Peer to Peer
Explanation
Peer-to-Peer is a network architecture or relationship model; Star, Ring, and Bus describe the physical layout (topologies).
Q.16 Which network topology typically requires the greatest amount of cabling for installation?
Star
Ring
Mesh
None of these
Explanation
Mesh topology requires the most wiring because every single node must be physically connected to every other node in the network.
Q.17 Which topology is characterized by having all nodes connected to a central hub?
Star
Ring
Mesh
None of these
Explanation
The defining characteristic of a Star topology is that all data passes through a central hub or switch.
Q.18 Which topology is commonly associated with the 'token passing' access method?
Star
Ring
Mesh
None of these
Explanation
In a Ring topology, a small packet called a ‘token’ moves around the circle, and only the device holding the token can transmit data.
Q.19 True or False: 'Bus' is a valid type of network topology.
True
False
N/A
None of these
Explanation
True. Bus topology is one of the fundamental physical layouts where all nodes share a single communication line.
Q.20 The mathematical term 'Topology' was originally introduced by?
Johann Benedict Listing
John
Robert
None of these
Explanation
Johann Benedict Listing first used the term ‘Topology’ in 1847, a concept later adapted into computer science to describe network layouts.
