An organization is expanding its network to include a new department within the same building. The network administrator needs to implement a segment that will effectively handle internal traffic for this department independently from the rest of the network. Which of the following is the BEST solution to maintain network segmentation while allowing centralized management?
Implement a Virtual Local Area Network (VLAN)
Set up a Storage Area Network (SAN)
Use subnetting to create a new IP address range.
Establish a Virtual Private Network (VPN) for the department
A VLAN (Virtual Local Area Network) enables network segmentation within a switch by dividing the network into smaller logical groups, improving performance and security while still under the management of the central switch. A SAN (Storage Area Network) is focused on providing access to consolidated, block-level storage, which is not directly related to traffic management or segmentation. A VPN (Virtual Private Network) extends a private network across a public network to provide remote users secure access to their network. Subnetting could be used for network segmentation but would not provide the ease of centralized management that a VLAN offers, thus VLAN is the best solution given the criteria mentioned.
