The Chief Information Officer (CIO) wants to implement a redundant server location to which the production server images can be moved within 48 hours and
services can be quickly restored, in case of a catastrophic failure of the primary datacenter’s HVAC. Which of the following can be implemented?

A.
Cold site

B.
Load balancing

C.
Warm site

D.
Hot site

Explanation:
Warm sites provide computer systems and compatible media capabilities. If a warm site is used, administrators and other staff will need to install and configure
systems to resume operations. For most organizations, a warm site could be a remote office, a leased facility, or another organization with which yours has a
reciprocal agreement.
Incorrect Answers:
A: 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.
B: Load balancing is a way of providing high availability by splitting the workload across multiple computers.
D: 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 preconfigured software to meet the needs of an organization.
