Layer 3 Switching — CompTIA Network+ (N10-009) Practice Questions
Layer 3 switching combines the hardware-based forwarding speed of a switch with the IP routing capabilities of a router, allowing inter-VLAN routing to occur within a single device. The N10-009 exam tests how Layer 3 switches use Switched Virtual Interfaces (SVIs) to assign IP addresses to VLANs and route between them without requiring traffic to leave the switch. This is important in enterprise LAN design because it reduces latency compared to routing through an external router. Candidates should understand when a Layer 3 switch is preferred over router-on-a-stick and how to identify it in a network topology question.
