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.
