Which function allows a Layer 3 switch to perform tasks that a Layer 2 switch cannot?
Filtering frames based on MAC addresses
Converting optical signals to electrical signals
Forwarding packets based on IP addresses
Providing Power over Ethernet to connected devices
Layer 3 switches can perform routing by forwarding packets based on IP addresses, enabling communication between different subnets. This is a function that Layer 2 switches cannot perform, as they only forward frames based on MAC addresses within the same subnet. Filtering frames based on MAC addresses is a function shared by both Layer 2 and Layer 3 switches. Providing Power over Ethernet (PoE) is related to supplying power over network cables and is not exclusive to either layer. Converting optical signals to electrical signals is the role of media converters, not switches.
