Questions and Answers

What is a Local Area Network (LAN)?

A group of devices in the same broadcast domain (correct)

A group of devices connected to different broadcast domains

Study Notes

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
