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?
Implement Virtual LANs (VLANs) and assign one for the accounting department and another for the marketing department.
Configure Access Control Lists (ACLs) on the switches to restrict inter-department traffic.
Keep the network as is without making any changes to segmentation.
Divide the network into smaller subnets without re-configuring switches or routers.
Creating separate VLANs for the accounting and marketing departments is the correct solution to establish distinct broadcast domains. This allows for segmenting the network based on different departments, which not only limits broadcasts to specific areas within the network but also improves overall security by controlling inter-department communication flows. Using ACLs on switches or subnets would not inherently create separate broadcast domains as they do not segment the network at Layer 2, and doing nothing would not improve separation or network performance.
