A customer is implementing a business continuity solution for the current data centers. The new location must mitigate the impact of a disaster in any existing data centers by providing an acceptable

An identical infrastructure facility ready to provide service, often referred to as a hot site or an active/standby site, directly supports the requirements by offering fully segregated Layer 2 and 3 fault domains, enabling low to no human intervention for restoration, achieving medium to high RPO/RTO, and being compatible with asynchronous storage replication.

A "mirrored inactive infrastructure facility with fully stretched resources" implies a stretched cluster/stretched Layer 2, which contradicts the "fully segregated Layer 2 and 3 fault domains" requirement, as it extends fault domains rather than segregating them.

A "cold infrastructure facility with basic infrastructure" implies a much higher RTO (Recovery Time Objective) and RPO (Recovery Point Objective) due to the the time required to provision and restore services, which does not meet the "medium to high RPO/RTO" requirement.

A "partially equipped infrastructure facility for on-demand activation" implies a warm site, which has a higher RTO than a hot site and would likely require more human intervention for full service restoration compared to an identical, ready-to-serve facility.
