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.
Create a new IP subnetting scheme for each department.
Keep the network as is without making any changes to segmentation.
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 broadcast traffic to specific areas but also improves overall security by controlling inter-department communication flows. While creating new IP subnets divides the network at Layer 3, it does not separate the broadcast domain at Layer 2 without an accompanying VLAN. ACLs are used to filter traffic but do not create separate broadcast domains. Doing nothing would not improve separation or network performance.
