The Logical Link Control sub-layer is a part of which of the following?

The correct answer is A. The ISO/OSI Data Link layer. In the IEEE 802 networking model, the Data Link layer (Layer 2) is subdivided into two sub-layers: the upper Logical Link Control (LLC) sub-layer (defined by IEEE 802.2) and the lower Media Access Control (MAC) sub-layer. LLC is responsible for flow control, error control, and pr

Explanation

In the IEEE 802 networking model, the Data Link layer (Layer 2) is subdivided into two sub-layers: the upper Logical Link Control (LLC) sub-layer (defined by IEEE 802.2) and the lower Media Access Control (MAC) sub-layer. LLC is responsible for flow control, error control, and providing a uniform interface to the Network layer above, regardless of the underlying physical medium. It is not part of the Reference Monitor (a security model concept), the TCP/IP Transport layer, or change management control.
