AAPC - Chapter 5 Review Exam Test with 100%
Verified Answers
Which two statements describe features or functions of the logical link
control sublayer in Ethernet standards? (Choose two.) - --The data link
layer uses LLC to communicate with the upper layers of the protocol suite.
-Logical link control is implemented in software.
*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).*
Which statement is true about MAC addresses? - -The first three bytes
are used by the vendor assigned OUI.
*A MAC address is composed of 6 bytes. The first 3 bytes are used for vendor
identification and the last 3 bytes must be assigned a unique value within the
same OUI. MAC addresses are implemented in hardware. A NIC needs a MAC
address to communicate over the LAN. The IEEE regulates the MAC
addresses.*
Which statement describes the treatment of ARP requests on the local link? -
-They are received and processed by every device on the local network.
