Given the strict two-hour maximum tolerable downtime, the corporation requires a disaster recovery solution that can be operational almost immediately after the failure of the primary site. A hot site is the best option because it is a fully operational data center that can take over operations seamlessly and with minimal to no downtime. Contrastingly, while a warm site is quicker to activate than a cold site, it still requires additional time to bring all services online fully. A cloud solution could potentially meet the needs but is not specific enough as cloud services can range from cold to hot configurations. Also, synchronous replication is a technology used to mirror data in real-time but does not denote a disaster recovery site type in itself.
