A network administrator is setting up a new switched network and wants to create separate broadcast domains for the accounting and marketing departments to improve network performance and enhance security. Which of the following would be the BEST solution to achieve this goal?
Keep the network as is without making any changes to segmentation.
Configure Access Control Lists (ACLs) on the switches to restrict inter-department traffic.
Divide the network into smaller subnets without re-configuring switches or routers.
Implement Virtual LANs (VLANs) and assign one for the accounting department and another for the marketing department.
