CompTIA A+ Certification 220-1001: The Total Course - Hubs vs. Switches

What is the primary function of a hub in a local area network?

• To filter data based on IP addresses

• To store data temporarily

• To repeat signals to all connected devices

• To amplify signals

What is a major drawback of using a hub in a network?

• It cannot connect to the internet

• It shares bandwidth among all devices, reducing speed

• It requires manual configuration

• It can only connect two devices

In the context of networking, what is the role of a repeater?

• To repeat signals to extend the network range

• To store data temporarily

• To convert data formats

• To filter data packets

How does a switch improve network efficiency compared to a hub?

• By amplifying signals

• By reducing the size of data packets

• By sending data only to the intended recipient

• By increasing the number of ports

What does a switch use to determine the destination of a data packet?

• IP address

• Port number

• MAC address

• Subnet mask

What is a key feature of a switch that makes it 'smart' compared to a hub?

• It can connect to wireless devices

• It can store data permanently

• It can operate without power

• It can memorize MAC addresses

Why are switches preferred over hubs in modern networks?

• They require less power

• They are cheaper

• They are easier to install

• They provide better data management and speed
