You are responsible for security at a building that has a lot of traffic. There are even a significant
number of non-employees coming in and out of the building. You are concerned about being able to
find out who is in the building at a particular time. What is the simplest way to accomplish this?

A.
Implement a sign in sheet at the main entrance and route all traffic through there.

B.
Have all people entering the building use smart cards for access.

C.
Implement biometric access.

D.
Implement cameras at all entrances.

Explanation:
A sign in sheet is very cost effective and can be implemented immediately. Put at a
receptionist’s desk, it adds almost no cost yet allows you
to find out who is in the building at a given time.
Answer option B is incorrect. To begin with this solution would entail significant costs. Furthermore,
it would be difficult to implement for nonemployees entering the building.
Answer option D is incorrect. This might work well, but would not be the simplest way to accomplish
the goal. It also would be moderately

expensive.
Answer option C is incorrect. This would be neither simple, nor cost effective. And it would be
difficult to coordinate with the non employees
entering the building.
