A relational database running on Amazon RDS for PostgreSQL is experiencing performance bottlenecks. CloudWatch metrics show high CPU utilization and high Read IOPS, while Write IOPS are low. Which TWO strategies should the architect implement to improve performance? (Select TWO)

Answer options:

Migrate to Amazon DynamoDB.

Create RDS Read Replicas and offload read queries to them.

Enable Multi-AZ deployments.

Increase the size of the EBS volumes to get more baseline IOPS.

Implement Amazon ElastiCache to cache frequently accessed data.

Use AWS Database Migration Service to migrate to Oracle.

How to approach this question

Identify solutions for a read-heavy relational database.

Full Answer

B, E

For a read-heavy workload causing CPU and IOPS bottlenecks, creating Read Replicas allows you to offload read traffic. Implementing a caching layer like ElastiCache prevents many read queries from ever hitting the database.

Common mistakes

Choosing Multi-AZ, which is a standby node and cannot serve read traffic.
