Amazon Web Services SAA-C03 Question Answer

An ecommerce company hosts a three-tier web application in a VPC. The web tier runs on Amazon EC2 instances in two Availability Zones. The company stores a product catalog and customer sales information in Amazon DynamoDB.

The company's finance team uses a reporting application to generate reports of daily product sales. When the finance team runs the daily reports, a sudden performance decrease affects website customers.

The company wants to improve the performance of the system.

Which solution will meet these requirements with MINIMAL changes to the current architecture?

Migrate the application to larger EC2 instances. Migrate the database to Amazon RDS for MySQL. Configure a read replica of the database in a second Availability Zone.

Increase the compute capacity of the EC2 instances. Migrate the database to Amazon ElastiCache (Memcached).

Implement DynamoDB Accelerator (DAX).

Configure DynamoDB streams.
