What is a characteristic of the LLC sublayer?
It provides the logical addressing required that identifies the device.
It provides delimitation of data according to the physical signaling requirements of the medium.
It places information in the frame that allows multiple Layer 3 protocols to use the same network interface and media.

37
Which media access method requires that an end device send a notification across the media before sending data?
CSMA/CA
CSMA/CD
deterministic
token passing
38
A frame is transmitted from one networking device to another. Why does the receiving device check the FCS field in the frame?
to determine the physical address of the sending device
to verify the network layer protocol information
to compare the interface media type between the sending and receiving ends
to check the frame for possible transmission errors
to verify that the frame destination matches the MAC address of the receiving device
39
What is an important function of the physical layer of the OSI model?
It accepts frames from the physical media.
It encapsulates upper layer data into frames.
It defines the media access method performed by the hardware interface.
It encodes frames into electrical, optical, or radio wave signals.
40
Which procedure is used to reduce the effect of crosstalk in copper cables?
requiring proper grounding connections
twisting opposing circuit wire pairs together
wrapping the bundle of wires with metallic shielding
designing a cable infrastructure to avoid crosstalk interference
avoiding sharp bends during installation
41
What are the three primary functions provided by Layer 2 data encapsulation? (Choose three.)
error correction through a collision detection method
session control using port numbers
data link layer addressing
placement and removal of frames from the media
detection of errors through CRC calculations
delimiting groups of bits into frames
conversion of bits into data signals
42
A PC is configured to obtain an IP address automatically from network 192.168.1.0/24. The network administrator issues the arp –a command and notices an entry of 192.168.1.255 ff-ff-ff-ff-ff-ff. Which statement describes this entry?
This is a static map entry.
This is a dynamic map entry.
This entry refers to the PC itself.
This entry maps to the default gateway.
43
What will a Layer 2 switch do when the destination MAC address of a received frame is not in the MAC table?
It initiates an ARP request.
It broadcasts the frame out of all ports on the switch.
It notifies the sending host that the frame cannot be delivered.
It forwards the frame out of all ports except for the port at which the frame was received.
44
What is the auto-MDIX feature on a switch?

A Layer 3 switch maintains an IP address table instead of a MAC address table.
A Layer 3 switch learns the MAC addresses that are associated with each of its ports. However, a Layer 2 switch does not.
