Which of the following is the BEST concept to maintain required but non-critical server availability?
A.
SaaS site
B.
Cold site
C.
Hot site
D.
Warm 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. Another term for a warm site/reciprocal site is active/active model.Incorrect Answers:
A: With a SaaS site you use applications as provided by a cloud provider over the internet.
B: 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.
C: 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,
