World of Computer Networking Your CCNA start - Negotiation of the Speed and Duplex

The video tutorial explains how different network devices handle collisions and negotiate speed and duplex settings. It covers the characteristics of fiber and copper cables, emphasizing the importance of full duplex over half duplex to avoid collisions and improve throughput. Practical recommendations are provided for network settings, including disabling half duplex on switches to ensure optimal performance.

What is a collision domain in the context of network switches?

• A device that connects multiple networks

• A protocol for data transmission

• A type of network cable

• A network segment where data packets can collide

Which type of cable does not support half duplex mode?

• Copper cable

• Fiber cable

• Coaxial cable

• Twisted pair cable

What is the main disadvantage of using half duplex mode?

• Increased data transmission speed

• Reduced likelihood of collisions

• Decreased throughput due to potential collisions

• Ability to send and receive data simultaneously

What happens if one of the wires in a fiber cable is broken?

• The link will automatically switch to copper

• The link will not come up at all

• The link will operate in half duplex mode

• The link will still function at reduced speed

What is the recommended setting for modern network switches regarding duplex mode?

• Disable half duplex on all ports

• Enable half duplex on all ports

• Disable full duplex on all ports

• Enable full duplex on all ports
