An organization has an Amazon Aurora RDS instance that handles all of its AWS-based e-commerce activity. The application accessing the database needs to create large sales reports on an hourly basis, running 15 minutes after the hour. This reporting activity is slowing down the e-commerce application.
Which combination of actions should be taken to reduce the impact on the main e-commerce application? Select 2 answers from the options given below.

Answer options:

A.Point the reporting application to the read replica.
B.Migrate the data to a set of highly available Amazon EC2 instances.
C.Use SQS Buffering to retrieve data for reports.
D.Create a read replica of the database.
E.Create an SQS queue to implement SQS Buffering.

Answer – A and D
The AWS Documentation mentions the following.
Amazon RDS Read Replicas provide enhanced performance and durability for database (DB) instances. This feature makes it easy to elastically scale out beyond the capacity constraints of a single DB instance for read-heavy database workloads. You can create one or more replicas of a given source DB Instance and serve high-volume application read traffic from multiple copies of your data, thereby increasing aggregate read throughput. 
Option B is incorrect, since the AWS RDS service already has features to support the requirement.
Options C and E are incorrect since using SQS would be inefficient.
