◉ A system combining heating, ventilating, and air conditioning
controls is known as: Answer: HVAC (Heating Ventilation Air
Conditioning)
◉ EMI shielding protects the transferred data from: (Select all that
apply) Answer: Outside Interference and Eavesdropping
◉ Setting up hot and cold aisles in a server room allows for more
efficient management of air flow. Answer: True
,◉ Which of the following answers list(s) example(s) of physical
security control types? (Select all that apply) Answer: Biometrics,

Answer: RAID 0
◉ Which of the following answers lists an example method for
passive test of security controls? Answer: Vulnerability scan
, ◉ Hardware-based RAID Level 1: (Select 3 answers) Answer: -
Requires at least 2 drives to implement
- Offers improved reliability by creating identical data sets on each
drive (failure of one drive does not destroy the array as each drive
contains identical copy of the data)
- also referred to as disk mirroring
◉ Hardware-based RAID Level 5: (Select 2 answers) Answer: -
Requires at least 3 drives to implement
- Offers increased performance and fault tolerance (single drive
failure does not destroy the array and lost data can be re-created
from the remaining drives)
◉ What is the function of archive bit? Answer: Indicating whether a
file has been modified since the last backup
◉ Which of the following terms refers to a backup technique that
allows for creating an exact copy of an entire drive and replicating
the drive to a new computer or to another drive on the same
computer in case of hard drive failure? (Select best answer) Answer:
Drive imaging
◉ In a differential backup strategy, restoring data from backup
requires only a working copy of the last full backup. Answer: False
