In Cisco SD-Access, virtual networks create segmentation that allows for separation of users and resources. How is this type of segmentation described?

"Stretched" typically refers to extending Layer 2 domains across physically separate locations, not the specific term for the segmentation provided by Virtual Networks in SD-Access.

Micro-segmentation in SD-Access is achieved using Security Group Tags (SGTs) to enforce granular, policy-based access control -within- a Virtual Network, not by the Virtual Networks themselves.

Virtual Networks (VNs) in Cisco SD-Access are used to implement macro-segmentation, providing broad, coarse-grained separation of users, devices, and resources into distinct routing and forwarding domains, ensuring their traffic is completely isolated from other VNs.

"Inter-VN" describes traffic that flows -between- different Virtual Networks, but it does not describe the -type of segmentation- that the Virtual Networks themselves provide.
