A company that purchased an HVAC system for the datacenter is MOST concerned with which of the
following?

A.
Availability

B.
Integrity

C.
Confidentiality

D.
Fire suppression

Explanation:
Availability means simply to make sure that the data and systems are available for authorized users. Data
backups, redundant systems, and disaster recovery plans all support availability; as does environmental
support by means of HVAC.
Incorrect Answers:
B: Integrity refers to data not being tampered with. HVAC does not tamper with data.
C: Confidentiality refers to measures used to prevent unauthorized users from accessing data. HVAC does
not keep users away or lure them.
D: Fire Suppression is but a component of HVAC and refers to the act of extinguishing fire vs preventing a
fire.
