Network Segmentation: Enhancing Departmental Separation

A.

The correct answer for the task of dividing the network so that each department is separate from the other is VLAN.

A VLAN (Virtual Local Area Network) is a logical grouping of devices on the same physical network. VLANs are used to divide a network into smaller logical networks or broadcast domains, which helps to reduce network congestion and improve security.

Each VLAN is identified by a unique VLAN ID (VID) and can be configured to communicate with other VLANs or to be isolated. By using VLANs, network administrators can control traffic between different departments or groups of users, and limit access to sensitive data or resources.

VPN (Virtual Private Network) is a technology used to create a secure, encrypted connection between two networks over the Internet. While VPNs can be used to connect remote users or sites to a company network, they do not provide network segmentation or isolation between different departments.

VNC (Virtual Network Computing) is a graphical desktop sharing system that allows remote control of another computer over a network. VNC is not used for network segmentation or isolation.

VM (Virtual Machine) is a software emulation of a computer system that runs on top of a physical host machine. While virtualization can be used to create multiple isolated virtual machines on a single physical server, it is not the best solution for network segmentation between different departments or user groups.
