CWAP Chapter 1 questions with correct answers

Data Link Sublayers Answer LLC sublayer MAC sublayer When the Network layer sends data to the Data-Link layer, the data is handed off to the LLC and becomes know as the MAC Service Data Unit (MSDU). A simple definition of the MSDU is that it is the data payload that contains the Answer IP Packet and some LLC data. 802.11 management and control frames do not carry Answer upper-layer information. Only data frames carry upper-layer information. The maximum frame body size Answer 2,304. The max frame body size is determined by the maximum size plus any overhead from encryption. When the LLC sends the MSDU to the MAC sublayer, the MAC header information is added to the MSDU and is now called Answer MAC Protocol Data Unit (MPDU). MPDU is an 802.11 frame. The IEEE standard defines communication mechanisms only at what layer? Answer Physical Layer and MAC sublayer of the Data-Link layer of the OSI model. At the Data-Link layer, a MAC header is added, and the IP Packet is encapsulated inside a Answer frame. At the Physical layer a ___ header with more information is added to the frame. Answer PHY
