|
Which two statements describe features or functions of the logical link control sublayer in Ethernet standards? (Choose two.)
|
|
Logical link control is implemented in software.
|
|
|
Logical link control is specified in the IEEE 802.3 standard.
|
|
|
The LLC sublayer adds a header and a trailer to the data.
|
|
|
The data link layer uses LLC to communicate with the upper layers of the protocol suite.
|
|
|
The LLC sublayer is responsible for the placement and retrieval of frames on and off the media.

Explanation:
Detailed explanation-1: -Logical Link Control (LLC) sublayer provides the logic for the data link. Thus, it controls the synchronization, flow control, and error checking functions of the data link layer. Media Access Control (MAC) sublayer provides control for accessing the transmission medium.
Detailed explanation-2: -The logical link control sublayer handles multiplexing, demultiplexing, flow control and error detection. In short, these roles mean that packets of data are sent parceled into frames. This is done at a rate both the sending and receiving systems can handle, without errors in the final data.
