Final answer:
The warm site offers limited capabilities and is the middle ground between fully equipped hot sites and the less-equipped cold sites, making it the answer to the question.
Step-by-step explanation:
The site that best provides limited capabilities for the restoration of services in a disaster is the warm site. Compared to hot and cold sites, a warm site is a compromise between the two. It is equipped with some hardware and connections, but it often requires additional resources, such as servers and storage systems, to become fully operational. A cold site would have space and utilities available, but it would lack the necessary hardware and could take days or weeks to set up, whereas a hot site would be fully equipped and ready to take over immediately. Therefore, a warm site provides limited functionality and can be operational in a shorter amount of time than a cold site, but with less immediacy compared to a hot site.
