Apply what you learned in SAA-style questions.

Choose one scenario, then answer SAA-style questions about its requirements and tradeoffs. After each answer, Arcflow explains why every option fits or fails.

Create an asynchronous read replica and send all writes to it after failure.Increase the primary DB instance class.Convert the database to an RDS Multi-AZ deployment.Take a manual snapshot every hour and restore it during an outage.

Practice uses original Arcflow exam-style questions. It is not an official AWS exam or AWS question bank.
