Which type of recovery site is MOST reliable and can support stringent recovery requirements?

[References: The CISM Review Manual 2023 defines a hot site as “a fully operational facility that mirrors the primary production center” and states that “a hot site can support stringent recovery requirements and provide the shortest recovery time” (p. 190). The CISM Review Questions, Answers & Explanations Manual 2023 also provides the following rationale for this answer: “A hot site is the correct answer because it is the most reliable type of recovery site and can support stringent recovery requirements, as it is a fully operational facility that mirrors the primary production center and can resume the critical business functions within minutes of a disruptive event” (p. 96). Additionally, the web search result 1 states that “the recovery site can be hot, warm, cold or mobile. Hot sites are facilities that mirror the primary production center” and that “hot sites are the most reliable and can support stringent recovery requirements” (p. 1)., , , , , , , , , ]
