Discuss how can Virtual Local Area Network (VLAN) provides security and manage traffic flow into a network. ====================================================== For your information "When compared to LANs, virtual local area networks (VLANs) have the benefit of lowering the amount of network traffic and collisions while also being more cost effective. In addition, a Virtual Local Area Network (VLAN) can provide an additional layer of protection. It is much simpler to stop a compromised computer from infecting the entire network if the devices are segmented into multiple virtual local area networks (VLANs), which are often organized by department." Explanation: Virtual Local Area Networks' Advantages The expansion and success of a company depends on the efficiency of its users and the flexibility of its networks. Virtual LANs simplify how networks can be built to help businesses succeed. Here are some of the most important gains from deploying VLANs: Confidentiality is protected by physically isolating groups that handle sensitive data from the rest of the network. Savings come from not having to invest as much money into upgrading the network and making better use of the resources you already have in place, namely bandwidth and uplinks. Gains in efficiency: Splitting a flat Layer 2 network into many logical workgroups (broadcast domains) helps to eliminate superfluous traffic and improve performance. Broadcast domains can be shrunk by partitioning a network into VLANs, as this will limit the number of nodes that are part of the broadcast domain. Figure 3-2 depicts a network topology with six nodes, each belonging to one of three distinct broadcast domains. There will be three types of attendees: teachers/students/guests. VLANs boost IT productivity since groups of users with similar network needs can be assigned to the same VLAN. When a new switch is provisioned, the ports are assigned based on the set of policies and procedures for that VLAN. Providing a VLAN with a descriptive name also makes it simple for IT professionals to understand its purpose. Figure 3-2 labels VLAN 10 as "Faculty," VLAN 20 as "Student," and VLAN 30 as "Guest" for clarity. VLANs make it easier to manage projects and applications by grouping together users and network equipment to meet organizational or geographic needs. A faculty e-learning development platform is an example of a specialized program that benefits from having its activities separated
