CompTIA Security Plus Mock Test Q421

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

Correct Answer: D
Section: Compliance and Operational Security

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.
