Question

question 13
what is a characteristic of the llc sublayer?
it defines software processes that provide services to the physical layer.
it places information in the frame allowing multiple layer 3 protocols to use the same network interface and media.
it provides the logical addressing required that identifies the device.
it provides delimitation of data according to the physical signaling requirements of the medium.

Explanation:

The Logical Link Control (LLC) sub - layer of the Data Link Layer places information in the frame to allow multiple Layer 3 protocols to share the same network interface and media. It provides a common interface to the upper - layer protocols. The first option is incorrect as LLC provides services to the Network layer, not the Physical layer. The third option is about the function of the Network layer for logical addressing. The fourth option is related to the Physical layer's function for data delimitation based on physical signaling requirements.

Answer:

It places information in the frame allowing multiple Layer 3 protocols to use the same network interface and media.
