Question 175 of 259
Single answerAn 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?
A. Create an Amazon Route 53 alias failover routing policy with values for AWS IoT Core data endpoints in both Regions Migrate data to Amazon Aurora global tables.
B. Create a domain configuration for AWS IoT Core in each Region. Create an Amazon Route 53 latency-based routing policy. Use AWS IoT Core data endpoints in both Regions as values. Migrate the data to Amazon MemoryDB for Redis and configure cross-Region replication.
C. Create a domain configuration for AWS IoT Core in each Region. Create an Amazon Route 53 health check that evaluates domain configuration health. Create a failover routing policy with values for the domain name from the AWS IoT Core domain configurations. Update the DynamoDB table to a global table.
D. Create an Amazon Route 53 latency-based routing policy. Use AWS IoT Core data endpoints in both Regions as values. Configure DynamoDB streams and cross-Region data replication.
