• Chose B1

  B Store contact info in DynamoDB + photo object keys pointing to S3 DynamoDB is perfect for structured contact details (name, email, phone…) with fast key-based lookups via AWS APIs S3 is designed for large binary files like high-resolution photos DynamoDB stores the S3 object key as an attribute, linking the two together Both services are native AWS, fully managed, and expose APIs → matches the requirements perfectly

• Chose B1

  This is the best solution because it uses AWS-native services that are scalable, serverless, and fully managed

• Chose B4

  A) Eliminated - DynamoDB is not cost-effective for storing large binary data and also increases query latency C) Eliminated - Cognito user pools are intended for user authentication and authorization, not as a storage solution
