Which of the following is a function of the MAC sublayer?
It is responsible for Media Access Control.
It handles communication between upper and lower layers.
It performs the function of NIC driver software.
It adds control information to network protocol layer data.
Which statement describes the logical link control sublayer in Ethernet standards?
Logical link control is specified in the IEEE 802.3 standard.
The LLC sublayer adds a header and a trailer to the data.
Logical link control is implemented in software 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.
Which of the following is used by the Data Link layer to determine the media access control method to be used to put frames onto the media?
Type of data
Transport layer protocols
Layer 3 IP protocol
Logical Topology
Which topology type would use point-to-point, hub and spoke, or mesh topologies?
WLAN
WAN
PAN
LAN
What type of access control is used for Wireless?
CMSA/Collision Avoidance
CMSA/Collision Detection
CMSA/Media Control
CMSA/Media Access
Why doesn't modern ethernet require a media access control method?
It uses one pair of wires for sending data.
It uses all wires for communication.
It uses half duplex.
It uses full duplex.
How does a receiving node identify the beginning and end of frames received from a continuous string of bits received from the medium?
The transmitting node sends an out-of-band signal to the receiver about the beginning of the frame.
The receiving node identifies the beginning of a frame by seeing a logical address.
The transmitting node sends a beacon to notify that a data frame is attached.
The transmitting node inserts start and stop bits into the frame.
Which of the following correctly identifies features provided by the frame header fields of the Data Link layer?
It identifies the Layer 3 protocol type and establishes flow control fields.
It contains the Layer 3 source and destination addresses used for route determination.
It establishes port connections between network applications.
It includes information about user applications.
What is the purpose of the CRC value that is found in the FCS trailer field of a frame?
To verify the integrity of the received frame.
To verify the physical address in the frame.
To verify the logical address in the frame.
To compute the checksum header for the data field in the frame.
What is the purpose of the CRC value that is found in the FCS trailer field of a frame?
