The correct answer is A. Add a read replica. B. Modify the application to use Amazon ElastiCache for Memcached. Migrating to DynamoDB or to an EC2 are clearly irrelevant. Creating a Multi-AZ RDS instance will not improve performance either. A read replica and/or a caching layer in front of the DB will reduce the traffic on the server.
