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; thesite 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.Dulaney, Emmett and Chuck Eastton, CompTIA Security+ Study Guide, 6th Edition, Sybex, Indianapolis,
