Which of the following floors would be most appropriate to locate information processing facilities in a 6-stories building? 

Answer options:

A. Basement
B. Ground floor
C. Third floor
D. Sixth floor

C

You data center should be located in the middle of the facility or the core of a building to provide protection from natural disasters or bombs and provide easier access to emergency crewmembers if necessary.By being at the core of the facility the external wall would act as a secondary layer of protection as well. Information processing facilities should not be located on the top floors of buildings in case of a fire or flooding coming from the roof.Many crimes and theft have also been conducted by simply cutting a large hole on the roof. They should not be in the basement because of flooding where water has a natural tendancy to flow down :-)Even a little amount of water would affect your operation considering the quantity of electrical cabling sitting directly on the cement floor under under your raise floor. The data center should not be located on the first floor due to the presence of the main entrance where people are coming in and out.You have a lot of high traffic areas such as the elevators, the loading docks,cafeteria, coffee shopt, etc..Really a bad location for a data center. So it was easy to come up with the answer by using the process of elimination where the top, the bottom, and the basement are all bad choices.That left you with only one possible answer which is the third floor.
