Which of the following is a benefit of using VLANs in a network?

Using VLANs (Virtual Local Area Networks) in a network provides improved security and segmentation, which is a significant benefit. VLANs allow network administrators to segment a single physical network into multiple logical networks. This logical separation means that devices within different VLANs cannot communicate with each other without an intermediary device, such as a router. This separation enhances security by isolating sensitive traffic from other types of traffic, reducing the risk of unauthorized access and making it harder for potential intruders to access critical resources.

Additionally, VLANs help organize and manage network resources more effectively by grouping users based on functional requirements rather than physical proximity. This structure not only enhances security but also allows for better performance management, as broadcast traffic is contained within VLANs, reducing unnecessary load on other segments of the network.

The other choices do not provide similar benefits. Decreased network speed is not a benefit, as VLANs aim to optimize performance rather than hinder it. Increased broadcast traffic runs counter to the purpose of VLANs, which is to reduce and isolate broadcast domains. Simplified physical cabling may not always apply, as VLANs operate within the logical framework, sometimes requiring additional configuration in the physical network setup. Thus, the most clear and consistent benefit of VLANs is the improved
