VLAN stands for Virtual Local Area Network. It is a technology that allows network administrators to logically partition a single physical network into multiple broadcast domains. VLANs have a number of benefits, some of which are mentioned below:

  1. Provides Segmentation: VLANs provide network segmentation, which is useful for separating broadcast domains, departmental traffic, and security. By dividing a large network into smaller ones, VLANs provide better control over network traffic and help to improve network performance.

  2. Added Security: VLANs provide added security by isolating traffic between different VLANs. By segregating traffic into VLANs, administrators can restrict access to certain network resources, and reduce the risk of unauthorized access to sensitive data.

  3. Dedicated Bandwidth: VLANs provide dedicated bandwidth, which ensures that each VLAN has its own dedicated portion of the network bandwidth. This helps to eliminate network congestion and improves network performance.

  4. Simplifies Network Management: VLANs simplify network management by allowing administrators to configure and manage logical groups of users or devices instead of managing individual ports or devices. This makes it easier to add or remove users or devices from the network.

  5. Allows Switches to Route Traffic between Subinterfaces: VLANs allow switches to route traffic between subinterfaces. This means that different VLANs can communicate with each other without the need for an external router.

  6. Contains Collisions: VLANs contain collisions, which is useful for reducing network congestion and improving network performance. By separating broadcast domains, VLANs reduce the amount of network traffic and the chances of collisions occurring.

Therefore, the two benefits provided by creating VLANs are: A. Added Security C. Provides Segmentation
