This episode explains Layer 3 switches, which combine the high-speed switching of Layer 2 with the routing capabilities of Layer 3. These devices can forward packets based on IP addresses, supporting inter-VLAN routing and more advanced network segmentation. The exam requires you to understand when and why a Layer 3 switch is used instead of a traditional router.

Examples include deploying Layer 3 switches in large campus networks where high-speed routing between VLANs is required. Troubleshooting considerations include verifying routing tables, ensuring VLAN interfaces are configured correctly, and identifying asymmetric routing problems. By recognizing the capabilities of Layer 3 switches, you’ll be able to differentiate them from routers and switches on the exam and apply them in complex enterprise designs.
