An organization wants to set up an offsite disaster recovery environment that will enable rapid resumption of IT operations following a disaster. The environment should be partially operational and capable of being fully functional within a moderate timeframe. Which type of disaster recovery site is MOST appropriate for these requirements?
A site that has infrastructure and some key systems in place, requiring minor setup for operations
A cloud service offering that can allocate resources on-the-fly, requiring setup and data synchronization
A site with the necessary facilities and services but without pre-installed hardware
A fully operational site with duplicate systems and up-to-the-minute replicated data
