Which of the following should be considered to mitigate data theft when using CAT5 wiring?

A.
CCTV

B.
Environmental monitoring

C.
Multimode fiber

D.
EMI shielding

Explanation:
EMI Shielding refers to the process of preventing electronic emissions from your computer systems from
being used to gather intelligence and preventing outside electronic emissions from disrupting your
information-processing abilities. Thus all wiring should be shielded to mitigate data theft.Incorrect Answers:
A: CCTV is used to record everything it sees, thus creating evidence in case of theft. Though data theft can
also occur over a network and a camera will only record the area where it is set up. Shielding is a more
important data theft mitigation measure.
B: Environmental monitoring is carried out by means of a HVAC system and furthermore shielding the
wiring is part of environmental monitoring.
C: Multimode fiber is not used to mitigate data theft.
