A.
Since the early days of mankind humans have struggled with the problems of protecting assets.

B.
The addition of a PIN keypad to the card reader was a solution to unreported card or lost card
problem.

C.
There has never been of problem of lost keys.

D.

Explanation:
This is absolutely false, this problem can be seen almost anywhere. There have always been trouble
with the lost of keys. Some of those looses are more important than others, its not the same to lost
the key of the company safe box, that lost the key of you locker with that contains your shoes. This is
obviously an incorrect statement, answer C is the one in here. “Unfortunately, using security guards
is not a perfect solution. There are numerous disadvantages to deploying, maintaining, and relying
upon security guards. Not all environments and facilities support security guards. This may be due
actual human incompatibility with the layout, design, location, and construction of the facility. Not
all security guards are themselves reliable. Prescreening, bonding, and training does not guarantee
that you won’t end up with an ineffective and unreliable security guard.” Pg 646 Tittel: CISSP Guide.
