    What is the purpose of the FCS field in a frame?

    to obtain the MAC address of the sending node

    to verify the logical address of the sending node

    to compute the CRC header for the data field

    to determine if errors occurred in the transmission and

    reception*

    8

    As data travels on the media in a stream of 1s and 0s how does

    a receiving node identify the beginning and end of a frame? 

    The transmitting node sends an out-of-band signal to the receiver

    about the beginning of the frame.

    The transmitting node sends a beacon to notify that a data frame is

    attached.

    The receiving node identifies the beginning of a frame by seeing a

    physical address.

    The transmitting node inserts start and stop bits into the

    frame.*

    Sending the signals asynchronously means that they are

    transmitted without a clock signal.*

    Signaling is a method of converting a stream of data into a

    predefined code.

    Wireless encoding includes sending a series of clicks to delimit the

    frames.

    In signaling, a 1 always represents voltage and a 0 always

    represents the absence of voltage.

    A network administrator is designing the layout of a new

    wireless network. Which three areas of concern should be

    accounted for when building a wireless network? (Choose

    three.)

    mobility options

    extensive cabling

    coverage area*

    interference*

    packet collision

    It converts a stream of data bits into a predefined code.

    It shields the upper layer protocol from being aware of the

    physical medium to be used in the communication.*

    It accepts Layer 3 packets and decides the path by which to

    forward a frame to a host on a remote network.

    It generates the electrical or optical signals that represent the 1 and

    0 on the media.

    12

    What is one advantage of using fiber optic cabling rather than

    copper cabling?

    It is easier to terminate and install than copper cabling.

    It is able to be installed around sharp bends.

    It is usually cheaper than copper cabling.

    It is able to carry signals much farther than copper cabling.*

    13

    Fill in the blank.

    What acronym is used to reference the data link sublayer that

    identifies the network layer protocol encapsulated in the frame?

    “LLC”

    14

    Why are two strands of fiber used for a single fiber optic

    connection?

    They allow for full-duplex connectivity.*

    They prevent crosstalk from causing interference on the

    connection.

    They increase the speed at which the data can travel.

    The two strands allow the data to travel for longer distances

    without degrading.

    Logical topologies determine the media access control method

    used.*

    Physical topologies are concerned with how a network transfers

    frames.

    The logical topology is always the same as the physical topology.

    17

    Fill in the blank.

    The term “Bandwidth” indicates the capacity of a medium to carry
