Question

A company has an application that uses an Amazon API Gateway REST API, AWS Lambda functions, and an Amazon DynamoDB table. The application currently runs in a single AWS Region. The company wants to make the application highly available across two Regions. User traffic must be routed to the Region that provides the least latency. Which combination of steps will meet these requirements? (Choose three.)

Accepted Answer

Correct answer: A, C, E. The correct answer is A, C, E. Option A: Create a replica of the DynamoDB table in a second Region. Option C: Create copies of the REST API and the Lambda functions in a second Region. Option E: Create health checks in Amazon Route 53. Create DNS records that include a latency routing policy. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. Amazon RDS is a managed relational database that handles patching, backups and failover. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
