The cable is labeled Rollover Cable.  What kind of connection is represented in the diagram based on the description?  A.Console connection  B.Ethernet connection  C.ISDN connection  D.Leased line connection  4.What is the purpose of encoding?  A.Identification of start and stop bits in a frame.  B.Denotes the physical layer connectors of computers in relation to the way they connect to the network media.  C.Controls the way frames are placed on the media at the Data Link Layer.  D.Represents the data bits by using different voltages, light patterns, or electromagnetic waves as they are placed onto the physical media.  5.What best describes the purpose of the Physical Layer?  A.Ensures reliable transmission of data across a physical link.  B.Determines connectivity and path selection between two end systems.  C.Establishes physical addressing, network topology, and media access.  D.Defines the functional specifications for links between end systems and the electrical, optical, and radio signals.  6.Through what process does UTP cable help to avoid crosstalk?  A.Shielding of cable  B.Twisting of pairs  C.Grounding the endpoints  D.Cladding in cable  7.Refer to the following diagram description to answer the question.  Diagram description:  PC A, B, and C, a switch, and a router are shown in specific locations on a building floorplan. The switch is connected to a router. The vertical dimension of the building floorplan is 75 meters. The horizontal dimension of the building floorplan is 125 meters.  The 3 PC's are connected to the switch with cables of varying lengths. The switch and router are located in the northeast corner of the floorplan. PC A is located in the southeast corner of the floorplan. PC B is located in the middle north of the floorplan, and PC C is located in the southwest corner of the floorplan.  The PC's have the following IP addresses:  PC A IP address: 192.168.1.13/24  PC B IP address: 192.168.1.11/24  PC A IP address: 192.168.1.12/24  The network in the diagram is wired with Cat 5e cable, and PC C is unable to communicate with the network. What Physical Layer problem would cause PC C to not connect to the network?  A.Wrong operating system  B.Incorrect IP address  C.Cable length  D.Incorrect prefix  E.Switch type  8.What are the advantages of using fiber optic cable over copper cable? (Choose three.)  A.Copper is more expensive  B.Immunity to electromagnetic interference  C.Careful cable handling  D.Longer maximum cable length  E.Efficient electrical current transfer  F.Greater bandwidth potential  9.What cable type would be used to connect a computer directly to another computer?  A.Straight-through  B.Rollover  C.Crossover  D.Console  10.Refer to the following diagram description to answer the question.  Diagram description:  The diagram shows fiber media cable components including, from the outermost to the innermost layer, the jacket (typically PVC), strengthening material (Aramid yarn), buffer, cladding, and core.  What is the purpose of cladding in fiber optic cables?  A.Cable grounding  B.Noise cancellation  C.Prevents light loss  D.EMI protection
