16.    C. Although both coax and fiber-optic would work, because the budget is extremely limited and there are only two stations, the best choice to run between the two stations would be coax cable. UTP and STP would not work because they’re limited to a maximum of 100 meters for Ethernet.


17.    A. The only network component listed that actually provides network printing service to network clients is the print server.


18.    B. Spikes are an overvoltage condition in which the power level quickly increases and then decreases just as quickly. A brownout is an inverted surge, and a blackout is a total loss of power for several seconds, several minutes, or several hours.


19.    A. Surges are an overvoltage condition in which the power level increases quickly and stays at a higher level for several seconds. A brownout is an inverted surge, and a blackout is a total loss of power for several seconds, several minutes, or several hours.


20.    C. Brownouts are an undervoltage condition in which the voltage level drops and stays low for several seconds. During a brownout, the lights usually dim and then become bright again.
