Which statement accurately describes a hot site in disaster recovery?

• A. Cold site is immediately operational.
• B. Warm site provides full production data.
• C. Hot site is a facility with full production data.
• D. Hot site provides immediate operational capability with live data and applications.

Answer: (D)

A hot site is a disaster recovery option built to keep operations running with no downtime by hosting fully configured IT systems at a separate location and keeping live data and applications ready to go. This arrangement means you can switch over to the hot site immediately and continue business as usual because the data is current and the applications are already running or can be brought online instantly. That’s why the statement describing immediate operational capability with live data and applications fits best.

Cold and warm sites describe different levels of readiness: a cold site provides space and infrastructure but no active systems or data, so it requires significant setup to become operational; a warm site has some hardware and data and may require time to restore and boot up systems, delaying full operation. Describing a hot site as simply having full production data misses the critical piece—that it’s ready to operate immediately with live data and live applications.
