Question

A company is currently in the design phase of an application that will need an RPO of less than 5 minutes and an RTO of less than 10 minutes. The solutions architecture team is forecasting that the database will store approximately 10 TB of data. As part of the design, they are looking for a database solution that will provide the company with the ability to fail over to a secondary Region. Which solution will meet these business requirements at the LOWEST cost?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Deploy an Amazon RDS instance with a cross-Region read replica in a secondary Region. In the event of a failure, promote the read replica to become the primary. Amazon RDS is a managed relational database that handles patching, backups and failover. This option delivers the requirement at the lowest cost.
