Which of the following can be utilized in order to provide temporary IT support during a disaster, where the organization sets aside funds for contingencies, but
does not necessarily have a dedicated site to restore those services?

A.
Hot site

B.
Warm site

C.
Cold site

D.
Mobile site

Explanation:
Not having a dedicated site means that the mobile site can fill the role of either being a hot, warm or cold site as a disaster recovery measure.
Incorrect Answers:
A: A hot site is a location that can provide operations within hours of a failure. This type of site would have servers, networks, and telecommunications equipment in
place to reestablish service in a short time. Hot sites provide network connectivity, systems, and preconfi gured software to meet the needs of an organization.
Databases can be kept up-to-date using network connections. These types of facilities are expensive, and they’re primarily suitable for short-term situations.
B: A warm site provides some of the capabilities of a hot site, but it requires the customer to do more work to become operational. Warm sites provide computer
systems and compatible media capabilities.
C: A cold site is a facility that isn’t immediately ready to use. The organization using it must bring along its equipment and network. A cold site may provide network
capability, but this isn’t usually the case; the site provides a place for operations to resume, but it doesn’t provide the infrastructure to support those operations.
