Networking Hardware NET1113/NET2123

What is the function of a network switch?

• The function of a network switch is to connect devices on a computer network.

• The function of a network switch is to encrypt data transmitted between devices on a computer network.

• The function of a network switch is to provide wireless connectivity to devices on a computer network.

• The function of a network switch is to control the flow of data between devices on a computer network.

Which device operates at the data link layer of the OSI model?

• switch

• firewall

• hub

• router

What is the main difference between a network bridge and a network hub?

• A network bridge operates at the application layer (Layer 7) of the OSI model, while a network hub operates at the transport layer (Layer 4).

• A network bridge can only connect two devices, while a network hub can connect multiple devices.

• A network bridge operates at the data link layer (Layer 2) of the OSI model and can connect two different network segments, while a network hub operates at the physical layer (Layer 1) and simply broadcasts all incoming data to all connected devices.

• A network bridge requires a power source to function, while a network hub does not require any power source.

Which networking device is responsible for forwarding data packets between different networks?

• switch

• hub

• router

• modem

What is the purpose of the network layer in the OSI model?

• The purpose of the network layer is to encrypt and decrypt data packets.

• The purpose of the network layer is to manage and control network devices.

• The purpose of the network layer is to compress and decompress data packets.

• The purpose of the network layer is to route and forward data packets across different networks.

Which layer of networking hardware is responsible for routing and forwarding data packets?

• Transport Layer

• Network Layer

• Data Link Layer

• Physical Layer

What is the primary function of a network bridge?

• To block data transmission between network segments

• To encrypt data transmitted between network segments

• To prioritize data transmission between network segments

• To connect multiple network segments together and forward data between them.

Which networking device operates at the physical layer of the OSI model?

• router

• switch

• firewall

• hub

What is the main advantage of using a router over a network switch?

• Increase network speed and performance.

• Connect multiple networks together and route data between them.

• Allow for easy network management.

• Provide wireless connectivity.

Which layer of the OSI model is responsible for logical addressing and routing?

• Data link layer

• Transport layer

• Physical layer

• Network layer
