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?

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?
Explanation:
The correct answer is C. To achieve business continuity with the ability to ingest and store data in two AWS Regions, the recommended solution involves creating a domain configuration for AWS IoT Core in each Region and implementing a failover routing policy using Amazon Route 53. Additionally, you need to update the DynamoDB table to a global table, ensuring data is synchronized across both regions. This approach allows for seamless failover between regions and ensures data availability, fulfilling the requirement for business continuity. Option C effectively meets these criteria without the need to replace DynamoDB with another database or handle the complexity of DynamoDB streams and cross-Region replication.
