Question

question 26 which two statements describe features or functions of the logical link control sublayer in ethernet standards? (choose two.) the llc sublayer adds a header and a trailer to the data. the llc sublayer is responsible for the placement and retrieval of frames on and off the media. logical link control is implemented in software. the data link layer uses llc to communicate with the upper layers of the protocol suite. logical link control is specified in the ieee 802.3 standard.

Explanation:

The LLC sub - layer of the data link layer in Ethernet standards is implemented in software and is used by the data link layer to communicate with upper layers of the protocol suite. Adding headers and trailers is more related to the MAC sub - layer, and the placement/retrieval of frames on/off the media is also a MAC sub - layer function. Logical link control is specified in IEEE 802.2, not 802.3.

Answer:

Logical link control is implemented in software.
The data link layer uses LLC to communicate with the upper layers of the protocol suite.
