Unit 3 - L2 - LAN

Which network topology allows for fast data transfer due to fewer collisions?

• Star

• Mesh

• Bus

• Ring

Answer explanation

The star topology minimizes collisions by connecting all devices to a central hub. This allows for direct communication between devices, leading to faster data transfer compared to bus or ring topologies.

In which network topology can network management be done centrally?

• Star

• Mesh

• Bus

• Ring

Answer explanation

In a star topology, all devices connect to a central hub or switch, allowing for centralized network management. This makes it easier to monitor and control the network compared to mesh, bus, or ring topologies.

Which network topology does not require a signal to be transmitted to all computers in the network?

• Star

• Mesh

• Bus

• Ring

Answer explanation

In a star topology, each computer is connected to a central hub. Signals are sent directly to the intended recipient, rather than being broadcast to all devices, making it efficient and reducing network traffic.

In which network topology does a node or device failure not affect the rest of the network?

• Star

• Mesh

• Bus

• Ring

Answer explanation

In a mesh topology, each node is connected to multiple other nodes. This redundancy means that if one node fails, the remaining nodes can still communicate through alternative paths, ensuring the network remains operational.

Which network topology can make network administration difficult?

• Star

• Mesh

• Bus

• Ring

Answer explanation

The mesh topology can complicate network administration due to its complexity and the number of connections between devices. Each device connects to multiple others, making troubleshooting and management more challenging compared to simpler topologies.

Which network topology requires additional hardware?

• Star

• Mesh

• Bus

• Ring

Answer explanation

The star topology requires a central hub or switch to connect all devices, which is additional hardware. In contrast, bus, mesh, and ring topologies can operate without such centralized devices.

Why has the company set up a LAN rather than a WAN?

• Because it is cheaper and suitable for a small area

• Because it provides faster internet speed

• Because it requires less hardware

• Because it is more secure

Answer explanation

The company set up a LAN because it is cheaper and suitable for a small area, making it a cost-effective solution for local networking needs compared to a WAN, which is designed for larger geographic areas.

What additional equipment is required besides desktop computers?

• File server, backup server, and two printers

• Two routers and a switch

• Three modems and a hub

• Four monitors and a scanner

Answer explanation

The correct choice includes a file server for data storage, a backup server for data protection, and two printers for document output, which are essential for a complete desktop computer setup.

What is the main purpose of setting up a LAN in the office?

• To connect devices within a small area

• To connect devices across multiple cities

• To provide internet access to the public

• To enhance security for online transactions

Answer explanation

The main purpose of setting up a LAN (Local Area Network) in an office is to connect devices within a small area, allowing for efficient communication and resource sharing among computers and peripherals.

What is the role of a file server in the office network?

• To store and manage files

• To provide internet access

• To print documents

• To backup data

Answer explanation

The primary role of a file server is to store and manage files, allowing users in an office network to access, share, and organize their documents efficiently. This makes 'To store and manage files' the correct choice.
