Which network configuration reduces background traffic while providing security protections?

A Virtual Local Area Network (VLAN) is an effective solution for reducing background traffic and providing security protections within a network.

VLANs allow network administrators to segment a physical network into multiple logical networks. This segmentation means that devices within the same VLAN can communicate directly with each other, while traffic from devices in different VLANs must go through a router. As a result, unnecessary broadcast traffic is minimized, as broadcast messages are confined to a single VLAN rather than propagating throughout the entire network. This leads to more efficient use of bandwidth and reduced background traffic.

Furthermore, VLANs enhance security by isolating sensitive data and devices from the rest of the network. For example, a VLAN can be created specifically for sensitive operations, effectively preventing unauthorized access from other departments within the organization. By restricting inter-VLAN communication and implementing access controls, a network can enforce stricter security protocols and reduce the risk of data breaches and other cybersecurity threats.

In contrast, Data Loss Prevention (DLP), Management VLAN, and File Integrity Monitoring serve different purposes. DLP focuses on preventing data exfiltration and ensuring that sensitive information is not improperly shared or sent outside the organization. A Management VLAN is a specific type of VLAN designated for administrative tasks, which can help
