An environmental company is deploying sensors in major cities throughout a country to measure air quality. The sensors connect to AWS IoT Core to ingest timeseries data readings. The company stores the data in Amazon DynamoDB.
For business continuity, the company must have the ability to ingest and store data in two AWS Regions.
Which solution will meet these requirements?
To meet the requirements of ingesting and storing data in two AWS Regions, you need to configure a domain for AWS IoT Core in each Region and ensure business continuity through a failover mechanism. Using Amazon Route 53 health checks and a failover routing policy ensures that data can be ingested if one Region becomes unavailable. Updating DynamoDB to a global table provides seamless cross-Region replication, allowing data to be stored consistently across Regions. This setup ensures high availability and data redundancy, fulfilling the company's requirements.

Option C Business continuity = Failover -> DynamoDB Global DB
its a C
Answer is C
Removed B because is replacing Dynamo, unnecessary
The only answer which configures DynamoDB properly for multi-region is C
For C, how failover routing policy have the ability to ingest and store data in two AWS Regions, there is only one active record
Answer: C
