An environmental company is deploying sensors across major cities in a country to measure air quality. These sensors are designed to connect to AWS IoT Core for ingesting time-series data readings, which are then stored in Amazon DynamoDB. To ensure business continuity, the company requires a solution that allows for the ingestion and storage of data across two AWS Regions. Which of the following solutions would effectively meet this requirement?
A
Implement an Amazon Route 53 alias failover routing policy with AWS IoT Core data endpoints in both Regions, and transition data storage to Amazon Aurora global tables.
B
Set up a domain configuration for AWS IoT Core in each Region, establish an Amazon Route 53 latency-based routing policy with AWS IoT Core data endpoints in both Regions, and switch data storage to Amazon MemoryDB for Redis with cross-Region replication.
C
Configure a domain configuration for AWS IoT Core in each Region, create an Amazon Route 53 health check to monitor domain configuration health, set up a failover routing policy with domain names from the AWS IoT Core domain configurations, and convert the DynamoDB table to a global table.
D
Establish an Amazon Route 53 latency-based routing policy with AWS IoT Core data endpoints in both Regions, and enable DynamoDB streams along with cross-Region data replication.
