Selected Answer: AB
A. Adding a read replica can offload read traffic from the primary RDS instance to the replica, thus improving performance during times of peak traffic. B. Amazon ElastiCache for Memcached is an in-memory data store that can be used to improve read performance.

Selected Answer: AB
A & B - 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.
