A technician has installed a group of layer 2 switches with multiple VLANs. The VLANs cannot talk to each other. Which of the following network devices could correct this problem? (Select TWO).

The correct answer is D. Layer 3 switch E. Router. Layer 2 switches operate only within a single broadcast domain (VLAN) and cannot route traffic between VLANs - inter-VLAN routing requires a Layer 3 device. A router can connect multiple VLANs using its interfaces or subinterfaces (router-on-a-stick). A Layer 3 switch combines…

Explanation

Layer 2 switches operate only within a single broadcast domain (VLAN) and cannot route traffic between VLANs - inter-VLAN routing requires a Layer 3 device. A router can connect multiple VLANs using its interfaces or subinterfaces (router-on-a-stick). A Layer 3 switch combines switching and routing capabilities, allowing it to route between VLANs directly. Hubs operate at Layer 1 and have no routing or VLAN awareness. DNS and DHCP servers provide name resolution and IP address assignment respectively - neither routes traffic between VLANs.
