A large financial services company uses Amazon ElastiCache for Redis for its new application that has a global user base. A database administrator must develop a caching solution that will be available across AWS Regions and include low-latency replication and failover capabilities for disaster recovery (DR). The company's security team requires the encryption of cross-Region data transfers.
Which solution meets these requirements with the LEAST amount of operational effort?

A. Enable cluster mode in ElastiCache for Redis. Then create multiple clusters across Regions and replicate the cache data by using AWS Database Migration Service (AWS DMS). Promote a cluster in the failover Region to handle production traffic when DR is required.

B. Create a global datastore in ElastiCache for Redis. Then create replica clusters in two other Regions. Promote one of the replica clusters as primary when DR is required.

C. Disable cluster mode in ElastiCache for Redis. Then create multiple replication groups across Regions and replicate the cache data by using AWS Database Migration Service (AWS DMS). Promote a replication group in the failover Region to primary when DR is required.

D. Create a snapshot of ElastiCache for Redis in the primary Region and copy it to the failover Region. Use the snapshot to restore the cluster from the failover Region when DR is required.
