Which of the following concepts is described as multiple logical subnets traversing the same physical network?

DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses to devices on a network, not to segment physical networks into logical subnets.

Virtual Local Area Networks (VLANs) allow network administrators to segment a single physical network switch into multiple distinct logical networks. Each VLAN acts as a separate broadcast domain, enabling different subnets to coexist and communicate independently over the same physical infrastructure.

A DMZ (Demilitarized Zone) is a security zone often used to host public-facing servers, logically separating them from internal networks, but it doesn't primarily describe multiple subnets on a single physical network.

VPNs (Virtual Private Networks) create secure connections over insecure networks, typically connecting remote users or networks, rather than segmenting a local physical network into multiple logical subnets.
