Which of the following statements pertaining to secure information processing facilities is
incorrect?

A.
Walls should have an acceptable fire rating.

B.
Windows should be protected by bars.

C.
Doors must resist forcible entry.

D.
Location and type of fire suppression systems should be known.

Explanation:
The correct answer can be determined through elimination. We need to have an
acceptable fire rating for the walls, this is well known for any CISSP aspirant, its like that because
we need to contain the fire as much as we can. We also need resistant doors so unauthorized
people do not enter easily using the force. The people also need to know about fire suppression
systems to be able to deal with a fire situation inside the facilities. As you can see, We should not
protect windows with bars, this is a bad practice because, in the case of a fire, the people cannot
get out of the building through the windows.
