Correct Answer: B
Section: Compliance and Operational Security
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. 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.
A: 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.
D: A co-location site is type of site where your web hosting is done, e.g. an ISP, or a web hosting company where many different customers host their web presence.
