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:Logical link control is implemented in software and enables the data link layer to communicate with the upper layers of the protocol suite. Logical link control is specified in the IEEE 802.2 standard. IEEE 802.3 is a suite of standards that define the different Ethernet types. The MAC (Media Access Control) sublayer is responsible for the placement and retrieval of frames on and off the media. The MAC sublayer is also responsible for adding a header and a trailer to the network layer protocol data unit (PDU).
