Explanation
The OSI Data Link Layer (Layer 2) is subdivided into two sublayers: the Logical Link Control (LLC) sublayer (upper) and the Media Access Control (MAC) sublayer (lower). The LLC sublayer provides flow control, error notification, and multiplexing of network-layer protocols. Layer 3 is the Network layer (routing/IP); Layer 4 is the Transport layer (TCP/UDP); Layer 5 is the Session layer. Remembering that LLC and MAC are both sub-layers of Layer 2 is a common exam topic.
