Network Implementation Routing, Switching, And Wireless Protocols Practice Test

Inter-VLAN routing is the process that lets devices in different VLANs communicate by moving packets between their separate IP subnets. A Layer 3 switch includes both switching and routing capabilities, so it can perform this routing internally. By creating a separate VLAN interface (an SVI) for each VLAN, the switch acts like a router for those subnets and can route traffic between them without sending it to an external router. It also typically serves as the default gateway for hosts in each VLAN, with IP addresses assigned to those SVIs. This setup combines fast hardware-based routing with streamlined network design, reducing latency and complexity. The other options aren’t devices or features that perform inter-VLAN routing: 10GBASE-T is just a physical Ethernet standard for 10 Gbps copper links, not a device. Sticky MAC is a security feature for learning and locking MAC addresses on ports. BPDU Guard is a Spanning Tree protection feature.
