Which device operates at both Layer 2 and Layer 3 in modern networks ?
Answer: D
The device working at both layer 2 and layer 3 is the multilayer switch.
A multilayer (layer 3) switch switches frames by MAC address within a VLAN, like an ordinary switch, and also routes packets between VLANs and subnets by IP address in hardware, combining the two functions in one device.
A hub works only at layer 1. A bridge works at layer 2, joining segments by MAC address. A router is a layer 3 device built for routing between networks rather than for layer 2 switching across many ports.
