Which logical segmentation method creates separate virtual local area networks on a network device?

The method that creates separate virtual local area networks (VLANs) on a network device is VLANs. VLANs allow network administrators to segment a single physical network into multiple logical networks, enabling better management of network traffic and improving security. By grouping devices into different VLANs, organizations can restrict communication between segments, thus isolating data and minimizing the risk of unauthorized access.

This logical segmentation allows for more efficient use of network resources and simplifies the management of different types of traffic. VLANs facilitate the separation of user groups, applications, or services without the need for additional hardware, making it a flexible and scalable solution for modern networking environments.

The other options, while they relate to various aspects of networking and security, do not specifically address the creation of separate virtual local area networks.
