In which of the following alternative processing sites is the backup facility maintained in a constant
order, with a full complement of servers, workstations, and communication links ready to assume
the primary operations responsibility?

A.
Hot Site

B.
Mobile Site

C.
Warm Site

D.
Cold Site

Explanation:
A hot site is a duplicate of the original site of the organization, with full computer
systems as well as near-complete backups of user data. It
provides the backup facility, which is maintained in a constant order, with a full complement of
servers, workstations, and communication links
ready to assume the primary operations responsibility.
A hot site is a backup site in case disaster has taken place in a data center. A hot site is located off
site and provides the best protection. It is
an exact replica of the current data center. In case a disaster struck to the data center,
administrators just need to take the backup of recent

data in hot site and the data center is back online in a very short time. It is very expensive to create
and maintain the hot site. There are lots
of third party companies that provide disaster recovery solutions by maintaining hot sites at their
end.
Answer option D is incorrect. A cold site is a backup site in case disaster has taken place in a data
center. This is the least expensive disaster
recovery solution, usually having only a single room with no equipment. All equipment is brought to
the site after the disaster. It can be on
site or off site.
Answer option B is incorrect. Mobile sites are self-reliant, portable shells custom-fitted with definite
telecommunications and IT equipment
essential to meet system requirements. These are presented for lease through commercial vendors.
Answer option C is incorrect. A warm site is, quite logically, a compromise between hot and cold
sites. Warm sites will have hardware and
connectivity already established, though on a smaller scale than the original production site or even
a hot site. These sites will have backups
on hand, but they may not be complete and may be between several days and a week old. An
example would be backup tapes sent to the
warm site by courier.
