  • 2. End devices are connected together by a bus and each bus connects to a central intermediate device.
  • 3. Each end system is connected to its respective neighbor via an intermediate device.
  • 4. All end and intermediate devices are connected in a chain to each other
ANSWER: 1
5 Which layer of the OSI model is responsible for specifying the encapsulation method used for specific types of media?
  • 1. application
  • 2. transport
  • 3. data link
  • 4. physical
ANSWER: 3

6 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?
  • 1. The transmitting node inserts start and stop bits into the frame.
  • 2. The transmitting node sends a beacon to notify that a data frame is attached.
  • 3. The receiving node identifies the beginning of a frame by seeing a physical address.
  • 4. The transmitting node sends an out-of-band signal to the receiver about the beginning of the frame
ANSWER: 1
7 The term_____ indicates the capacity of a medium to carry data and it is typically measured in kilobits per second (kb/s) or megabits per second (Mb/s).

     ANSWER: BANDWIDTH

    ANSWER: LCC

10 What is the function of the CRC value that is found in the FCS field of a frame?
  • 1. to verify the integrity of the received frame
  • 2. to verify the physical address in the frame
  • 3. to verify the logical address in the frame
  • 4. to compute the checksum header for the data field in the frame
ANSWER: 1
