A cloud provider has two cloud environments (Cloud A and Cloud B) that are in different

A. The Zero Downtime pattern can be applied to establish a cross-cloud failover system for the two Cloud Service A implementations. The Cross-Storage Device Vertical Tiering pattern can be applied to vertically scale data in Cloud Storage Device A across multiple other cloud storage devices dynamically. The Centralized Remote Administration pattern can be applied to establish a logical network perimeter around Organization A's IT resources, thereby protecting them from other cloud consumer organiza
B. The Dynamic Failure Detection and Recovery pattern can be applied so that if Cloud Service A in Cloud A fails, a watchdog system attempts to automatically recover Cloud Service A. Assuming Cloud Storage Device A has support for multiple disk types, the Intra- Storage Device Vertical Data Tiering pattern can be applied so that Cloud Storage Device A is equipped with dynamic vertical scaling. The Resource Management pattern can be applied to allow cloud consumer organizations to perform management
C. The Load Balanced Virtual Server Instances pattern can be applied to balance the virtual servers hosting Cloud Service A implementations across the two cloud environments. The Storage Workload Management pattern can be applied to balance workloads across both Cloud Storage Device A implementations. The Resource Reservation pattern can be applied to establish a physical network boundary around Organization A's IT resources, thereby protecting them from other cloud consumer organizations.
D. None of the above.
