A company runs an IoT platform on AWS. IoT sensors in various locations send data to the company's Node.js API servers on Amazon EC2 instances running behind an Application Load Balancer. The data is stored in an Amazon RDS MySQL DB instance that uses a 4 TB General Purpose SSD volume. The number of sensors the company has deployed in the field has increased over time, and is expected to grow significantly. The API servers are consistently overloaded and RDS metrics show high write latency. Which of the following steps together will resolve the issues permanently and enable growth as new sensors are provisioned, while keeping this platform cost- efficient? (Choose two.) A. Resize the MySQL General Purpose SSD storage to 6 TB to improve the volume's IOPS B. Re-architect the database tier to use Amazon Aurora instead of an RDS MySQL DB instance and add read replicas C. Leverage Amazon Kinesis Data Streams and AWS Lambda to ingest and process the raw data D. Use AWS X-Ray to analyze and debug application issues and add more API servers to match the load E. Re-architect the database tier to use Amazon DynamoDB instead of an RDS MySQL DB instance  Suggested Answer: CE Community Answer: CE This question is in SAP-C01 AWS Certified Solutions Architect – Professional Exam For getting AWS Certified Solutions Architect – Professional Certificate Disclaimers: The website is not related to, affiliated with, endorsed or authorized by Amazon.
