Networking Basics Quiz

At which OSI layer does a router operate?

• Physical Layer

• Data Link Layer

• Network Layer

• Transport Layer

How do routers help reduce network congestion?

• By amplifying signals

• By dividing broadcast domains

• By storing data packets temporarily

• By prioritizing certain types of data

Which of the following is a key feature of a router's dynamic routing table?

• It stores only static routes

• It updates based on network conditions

• It operates at the Physical Layer

• It does not affect network performance

What is one of the key benefits of using a switch in a network?

• Reduced power consumption

• Full-duplex operation, allowing simultaneous sending and receiving of data

• Larger physical size

• Lower cost compared to hubs

What does a switch use to forward frames to the correct port?

• IP addresses

• MAC addresses

• Subnet masks

• Gateway addresses

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

• Amplify network signals

• Broadcast incoming data to all connected devices

• Connect devices in different networks

• Manage network traffic

Which of the following best describes the difference between a hub and a repeater?

• A hub amplifies signals, while a repeater broadcasts data to all devices

• A hub connects devices in a LAN, while a repeater extends network signals

• A repeater has many ports, while a hub has only two ports

• Both a hub and a repeater filter network traffic

At which OSI model layer does a network hub operate?

• Data Link Layer

• Network Layer

• Physical Layer

• Application Layer

What is the main function of an active hub?

• Connect devices without amplifying the signal

• Amplify and regenerate data signals to maintain network performance

• Monitor network traffic

• Filter data packets based on IP addresses

Which type of hub offers additional features like network traffic management and monitoring?

• Passive Hub

• Active Hub

• Smart Hub

• Wireless Hub
