Which of the following is the disaster recovery site option that provides the least expensive disaster
recovery solution?

A.
Hot site

B.
Cold site

C.
Strong site

D.
Warm site

Explanation:
It is a nightmare for an organization if its data center is struck with a disaster. The losses are high and
the time wasted in recovering from the situation is immense. A company must think of a plan to
recover from such disasters. Without such plans, a company can be out of business in case its
headquarters’ building totally burned down from fire or any such disaster. To combat such
situations, companies create sites at which the data center of the company can be recreated. These
sites are of three types; cold, warm and hot site.
Cold sites

A cold site provides the least expensive disaster recovery solution. Such sites are usually having only
a single room with no equipment. All equipment is brought to the site after any disaster. It can be on
site or off site. The recovery from disaster takes lots of time.
Warm sites
The warm site contains a lot of equipments to create a semi-duplicate of the current data center. In
case of disaster, it is required taking offsite backups and some restoration work for making data
center up and running. A warm site becomes online in much less time than a cold site. It is more
expensive than cold site to create and maintain the warm site. The warm sites can be off site or on
site.
Hot sites
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.

C is incorrect. There is no such disaster recovery site option.
