Quiz on Network Architecture and Topology

What role does a server play in a client/server architecture?

• To facilitate communication between clients

• To manage and distribute resources

• To serve as a backup for client data

• To execute client requests directly

Answer explanation

In a client/server architecture, the server's primary role is to manage and distribute resources, ensuring that clients can access the necessary data and services efficiently. This makes 'To manage and distribute resources' the correct choice.

Which of the following is a characteristic of a peer-to-peer network?

• Has a hierarchical structure

• Is limited to two computers

• All nodes act as both servers and clients

• Requires a central server

Answer explanation

In a peer-to-peer network, all nodes can function as both servers and clients, allowing for direct communication and resource sharing without a central server. This distinguishes it from hierarchical or client-server models.

Lily is setting up a computer network for her school project. What is a disadvantage of star topology?

• Requires less cable than bus topology

• Easy to add new devices

• Central device failure affects the entire network

• All data flows in one direction

Answer explanation

In star topology, if the central device fails, the entire network goes down, making it a significant disadvantage. This contrasts with other topologies where the failure of one device does not necessarily impact the whole network.

What is a characteristic of a ring topology in networking?

• Each device is connected to two other devices

• It requires a central server to manage data flow

• Data can be sent in both directions

• It is the most common topology used in modern networks

Answer explanation

In a ring topology, each device is indeed connected to exactly two other devices, forming a circular data path. This characteristic distinguishes it from other topologies, making the first answer choice correct.

What is a primary disadvantage of bus topology?

• High cost of installation

• Single point of failure

• Complexity in adding new devices

• Requires more cable length

Answer explanation

The primary disadvantage of bus topology is the single point of failure. If the main cable fails, the entire network goes down, affecting all connected devices, which can lead to significant disruptions.

Which network topology connects all devices to a single central hub?

• Star topology

• Ring topology

• Bus topology

• Mesh topology

Answer explanation

The star topology connects all devices to a single central hub, allowing for easy management and troubleshooting. In contrast, ring, bus, and mesh topologies have different connection methods that do not center around a single hub.

In a classroom setting, what is a disadvantage of a ring topology used for connecting computers?

• Data can transfer at high speeds

• Easy to add additional workstations

• All data must pass through each workstation

• No server is needed

Answer explanation

In a ring topology, all data must pass through each workstation, which can create delays and bottlenecks. This is a significant disadvantage compared to other topologies where data can be routed more efficiently.

Which of the following best describes a star topology in networking?

• A layout where all devices are connected to a single central hub

• A configuration where devices are connected in a circular manner

• A setup that uses a mesh of interconnected devices

• A design where devices are connected in a line

Answer explanation

A star topology is characterized by all devices being connected to a single central hub, allowing for easy management and troubleshooting. This distinguishes it from circular, mesh, or linear configurations.

Which network architecture allows users to store files on their individual PCs?

• Bus topology

• Peer-to-peer network

• Ring topology

• Client/server network

Answer explanation

A client/server network allows users to store files on their individual PCs, as clients can access shared resources from a central server. In contrast, peer-to-peer networks enable direct file sharing between users without a central server.

What is a common disadvantage of bus topology?

• It requires a central device

• It is the most cost-effective topology

• It is difficult to identify problems

• It allows for high-speed data transfer

Answer explanation

In bus topology, all devices share a single communication line, making it challenging to pinpoint issues. If a fault occurs, it can disrupt the entire network, complicating troubleshooting efforts.
