World of Computer Networking Your CCNA start - Disadvantages of the Switched Network

The video tutorial discusses switched networks, explaining how devices are interconnected using switches that operate at the physical and data link layers of the TCP/IP model. It highlights two main disadvantages: broadcast storms caused by broadcast frames and the limitations of large MAC address tables. The tutorial suggests using routers and logical IP addresses to interconnect different switched networks, providing a solution for large-scale networks.

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

• To encrypt data

• To store IP addresses

• To switch frames as quickly as possible

• To route packets between different networks

What is a broadcast frame in a switched network?

• A frame that is encrypted

• A frame sent to all devices in the network

• A frame that is discarded by the switch

• A frame sent to a specific MAC address

What is a broadcast storm?

• A type of network security attack

• A situation where a single frame is sent to a specific port

• A network condition where broadcast frames flood the network

• A method to prevent data loss

What happens when a switch's MAC address table reaches its limit?

• The switch encrypts all data

• The switch drops some MAC addresses from the table

• The switch stops forwarding frames

• The switch shuts down

How does a switch behave when it encounters an unknown destination MAC address?

• It forwards the frame to a specific port

• It discards the frame

• It forwards the frame to all ports

• It encrypts the frame

Why is a switched network not ideal for very large networks?

• Because it gets flooded with broadcast frames

• Because it requires too many routers

• Because it cannot handle encrypted data

• Because it is too expensive

What is the solution to interconnect different switched networks?

• Using larger MAC address tables

• Using more broadcast frames

• Using routers and logical IP addresses

• Using only switches
