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.
