- C.A hot site is rented by the hour during a disaster, a warm site is rented by the month, and a cold site is owned only by the largest firms
- D.A hot site relies on nightly tape restores, a warm site mirrors data continuously, and a cold site holds only spare network cables

A hot site is a fully operational replica ready for immediate failover, a warm site has partial infrastructure that needs some setup, and a cold site has only basic facilities requiring full provisioning.
