Topic 1 Question 217
A company runs a global web application on Amazon EC2 instances behind an Application Load Balancer. The application stores data in Amazon Aurora. The company needs to create a disaster recovery solution and can tolerate up to 30 minutes of downtime and potential data loss. The solution does not need to handle the load when the primary infrastructure is healthy.
What should a solutions architect do to meet these requirements?
Deploy the application with the required infrastructure elements in place. Use Amazon Route 53 to configure active-passive failover. Create an Aurora Replica in a second AWS Region.
Host a scaled-down deployment of the application in a second AWS Region. Use Amazon Route 53 to configure active-active failover. Create an Aurora Replica in the second Region.
Replicate the primary infrastructure in a second AWS Region. Use Amazon Route 53 to configure active-active failover. Create an Aurora database that is restored from the latest snapshot.
Back up data with AWS Backup. Use the backup to create the required infrastructure in a second AWS Region. Use Amazon Route 53 to configure active-passive failover. Create an Aurora second primary instance in the second Region.

- 正解だと思う選択肢: A
A is correct.
- "The solution does not need to handle the load when the primary infrastructure is healthy." => Should use Route 53 Active-Passive ==> Exclude B, C
- D is incorrect because "Create an Aurora second primary instance in the second Region.", we need to create an Aurora Replica enough.

I am confused within A and D but I think D is the answer because this seems to be a cost related problem, a replica is kind of a standby and you can promote to be the main db anytime without any much downtime, but here it says it can withstand 30 mins of downtime so we can just keep a backup of the instance and then create a DB whenever required from the backup, hence less cost

The solution does not need to handle the load when the primary infrastructure is healthy. -> Amazon Route 53 active-passive failover -> A,D The company can tolerate up to 30 minutes of downtime and potential data loss -> backup -> D you don't have to use read replicas if you can tolerate downtime and data loss.
