A company runs an order system on EC2 with a self-managed PostgreSQL database, a self-managed RabbitMQ broker, and a shared file server for attachments. The team wants to reduce patching, backups, and cluster administration while keeping the architecture simple and using managed services where possible. Which three changes should they make? Select three.

Keep the database on EC2 and add more EBS volumes.

This keeps the database self-managed, so the team still owns patching, backups, and instance administration. More EBS volumes may expand storage, but they do not eliminate the operational burden.

Move RabbitMQ to Dedicated Hosts for better isolation.

Dedicated Hosts address tenancy or licensing requirements, not operational simplification. They do not provide a managed broker and would not reduce the need to administer RabbitMQ itself.

What does this SAA-C03 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: Replace the database with Amazon RDS for PostgreSQL. — The best way to reduce operational work is to replace each self-managed component with an AWS managed equivalent. RDS for PostgreSQL removes most database administration tasks. Amazon MQ provides a managed RabbitMQ-compatible broker so the team can stop managing broker nodes and clusters. S3 removes the need to operate a shared file server for attachments while preserving simple application access to object storage. Keeping the database on EC2 leaves the administration burden in place, and Dedicated Hosts do not turn RabbitMQ into a managed service. Those options fail to reduce patching, backups, and cluster operations.

What should I do if I get this SAA-C03 question wrong?

Then try more questions from the same exam bank and focus on understanding why the wrong options are tempting.
