LAN Broadcast Domains Quiz

Local Area Network (LAN)

• A LAN is a computer network that spans a small geographic area, typically within a building or campus

Network Segmentation

• Separating devices into different broadcast domains within a LAN can help improve network performance, security, and management
• Segmenting a network into smaller pieces contributes to network management by reducing network congestion, improving security, and enhancing troubleshooting

Drawbacks of Separate Switches

• Disadvantages of using separate switches for different broadcast domains within a LAN include increased cost, complexity, and network downtime

Inefficient Network Setup

• Inefficient network setups can lead to network congestion, security breaches, and management challenges

Purpose of Segmenting Devices

• The primary purpose of connecting devices to separate switches based on their required network access is to improve network security, performance, and management

VLAN Technology

• VLAN (Virtual Local Area Network) technology is used to virtually separate devices on the same physical switch into different networks
• VLANs allow for network segmentation without the need for separate physical switches
• The main advantage of using VLANs in a network is improved network management, security, and performance

Virtual Private Network (VPN)

• VPN stands for Virtual Private Network
• The primary purpose of a VPN is to securely connect devices over the internet
• A VPN concentrator is a device that manages VPN connections
• Routers and firewalls often integrate a VPN concentrator
• VLAN 1 typically represents the default VLAN on a switch

VPN Benefits

• Data is automatically encrypted when sent over a VPN connection
• The main purpose of using a VPN in a coffee shop is to secure internet connections
• When using a VPN, data and login credentials are automatically encrypted
