G8 Networks L3 Quiz

What is a network topology?

• A device that connects two networks

• A program that protects a network from hackers

• The layout of how devices are connected in a network

• The total number of devices in a network

What is a node in a network?

• The central cable in a bus topology

• A special type of network switch

• A device connected to the network, like a computer or printer

• A tool used to repair broken networks

In a star topology, each device connects to:

• Every other device directly

• A shared single cable

• Two other devices

• A central hub or switch

What is the role of the hub/switch in a star topology?

• Store data for all users

• Send data to all devices at once

• Direct data to the correct device

• Block any outside connections

One advantage of a star topology is:

• It doesn’t need any cables

• If one device fails, the rest still work

• It’s the cheapest topology

• It doesn’t need a central device

What is a major disadvantage of a bus topology?

• It needs a lot of cable

• It uses too many switches

• A single cable failure stops the whole network

• It only works with two devices

Which topology uses a backbone cable?

• Star

• Ring

• Bus

• Hybrid

In a bus network, what happens when two devices send data at the same time?

• The faster one wins

• The hub stores both messages

• The data collides and causes errors

• The switch chooses which data to accept

How is data passed in a ring topology?

• All at once to all devices

• In both directions

• In one direction around a loop

• Directly to the destination

What does “relay” mean in a ring topology?

• Devices can switch roles

• Data is passed from device to device until it reaches the destination

• Devices jump over each other to send data

• The switch relays the data to all users
