Which of the following computer recovery sites is the least expensive and the most difficult to test?
A.
non-mobile hot site.
B.
mobile hot site.
C.
warm site.
D.
cold site.
Explanation:
A cold site is less expensive compared to a warm site or a hot site. A cold site is a leased or rented facility that
supplies the basic environment, electrical wiring, air conditioning, plumbing, and flooring, but none of the
equipment or additional services. A cold site is essentially an empty data center.
Incorrect Answers:
A: A hot site is fully equipped and is therefore more expensive than a cold site.
B: A mobile (rolling) hot site is a mobile facility, typically the back of an 18-wheel truck. It has all of the
capabilities of a hot site and is very versatile, but expensive.
C: A warm site is more expensive than a cold site, since it is a leased or rented facility that is usually partially
configured with some equipment, such as HVAC, and foundational infrastructure components, but not the
actual computers.Harris, Shon, All In One CISSP Exam Guide, 6th Edition, McGraw-Hill, 2013, p. 921
