Answer Description

VLANs (Virtual Local Area Networks) operate at Layer 2 of the OSI model and enable a network engineer to create multiple, isolated broadcast domains on a single physical network infrastructure without requiring additional hardware. This allows for improved network segmentation and traffic management. Subnetting operates at Layer 3 by dividing networks based on IP addresses. Routing and NAT (Network Address Translation) are also Layer 3 functions and do not provide Layer 2 segmentation capabilities.
