For budget purposes, the accounting department has asked an administrator to provide a disaster recovery solution that will comply with the following requirements: Systems have to be operational…

A warm site has pre-installed hardware and partial configuration, allowing systems to become operational within hours to a couple of days - satisfying the 48-hour RTO. It is significantly less expensive than a hot or mirrored site, which aligns with the accounting department's budget constraints while still meeting the recovery window.

A cold site provides only the physical space, power, and cooling with no pre-installed equipment, meaning setup time typically exceeds two days and would violate the stated RTO.

A hot site is a fully operational duplicate running in real time, which meets the RTO but is the most expensive option and therefore not the best fit for a budget-conscious accounting department.

A mirrored site maintains a real-time synchronized copy and offers near-zero RTO, but its cost is even higher than a hot site, making it unsuitable given the budget requirement.
