Which capability is provided by a Layer 3 switch but not by a Layer 2 switch?
Forwarding frames within the same VLAN based on destination MAC address
Adding and interpreting IEEE 802.1Q VLAN tags on trunk links
Routing traffic between different IP subnets by using Switched Virtual Interfaces (SVIs)
Learning source MAC addresses and populating a CAM table
Layer 3 switches include hardware and software to inspect Layer 3 information (IP addresses) and maintain routing tables, allowing them to route traffic between separate IP subnets or VLANs via Switched Virtual Interfaces (SVIs). A Layer 2 switch cannot perform this routing; it can only forward frames within a single subnet based on MAC addresses. Functions such as MAC learning, VLAN tagging, and basic frame forwarding are common to both types of switches.
