Which of the following is a benefit of using a VLAN?

Using a VLAN (Virtual Local Area Network) provides several benefits, one of which is enhancing network security by isolating traffic. By segmenting a physical network into multiple virtual networks, VLANs can separate different types of traffic, ensuring that sensitive information remains shielded from general network access. For example, a VLAN can be created to keep finance department communications separate from those of the marketing department. This isolation helps to prevent unauthorized access to sensitive data and reduces the risk of network attacks, as the segmentation limits the broadcast domain to a smaller subset of devices.

In addition to security, VLANs can help improve network performance by reducing broadcast traffic, although this is not directly related to traffic isolation. By limiting interactions to VLAN members, organizations can manage and secure their networks more effectively, allowing for specific security policies and access control measures per VLAN.
