Which trait describes a Layer 2 switch?

A Layer 2 switch operates at the Data Link layer (Layer 2) of the OSI model. Its primary function is to forward data frames between devices within the same local area network (LAN) based on the destination Media Access Control (MAC) address. The switch builds and maintains a MAC address table, mapping MAC addresses to specific ports. When a frame arrives, the switch looks up the destination MAC address in its table to determine the correct outgoing port, then forwards the frame only to that port. "Ensures ordered delivery of data" is a function typically associated with the Transport layer (Layer 4), specifically TCP. "Maintains stateful session information" is also a characteristic of the Transport layer (Layer 4) or higher-layer firewalls. "Filters traffic using transport-layer protocols" describes a function of a Layer 4 firewall or router, not a fundamental Layer 2 switch operation.
