CompTIA Security Plus Mock Test Q347

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

Correct Answer: A
Section: Compliance and Operational Security

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.
