A cold site is a backup facility that provides infrastructure (such as power, cooling, and space) but does not have active IT resources installed. When a disaster occurs, IT teams must bring in and configure all necessary hardware and software before services can resume. This process can take weeks or longer-which matches the scenario described.
*Why not the other options?
*Hot site (A) - A hot site is a fully operational backup facility with up-to-date data and pre-configured hardware, allowing almost instant failover (minutes to hours).
*Warm site (B) - A warm site has pre-installed hardware and some software/configurations, but it requires some setup before becoming fully operational (hours to a few days).
*Active-active approach (D) - This means that multiple sites run simultaneously with load balancing, ensuring no downtime in case of a failure.
