Remember this is a NOT question. Hot sites do not provide a false sense of security since they are the best disaster recovery alternate for backup site that you rent.

A Cold, Warm, and Hot site is always a rental place in the context of the CBK. This is definivily the best choices out of the rental options that exists. It is fully configured and can be activated in a very short period of time.

Cold and Warm sites, not hot sites, provide a false sense of security because you can never fully test your plan.

In reality, using a cold site will most likely make effective recovery impossible or could lead to business closure if it takes more than two weeks for recovery.
