Which combination of steps should the SysOps administrator take to meet these requirements MOST cost-effectively?
(Choose two.)
Configure Aurora backups to be exported to the DR Region.
Configure the Aurora cluster to replicate data to the DR Region by using the Aurora global database option.
Configure the DR Region with an ALB and an Auto Scaling group. Use the same configuration as in the primary Region.
Configure the DR Region with an ALB and an Auto Scaling group. Set the Auto Scaling group’s minimum capacity, maximum capacity, and desired capacity to 1.
Manually launch a new ALB and a new Auto Scaling group by using AWS CloudFormation during a failover activity.
Explanations:
Exporting Aurora backups to the DR region is not necessary because Aurora automatically handles cross-region replication and failover without requiring manual backup exports.
Aurora Global Databases provide cross-region replication with low-latency, allowing for automatic failover and meeting the RTO and RPO objectives.
Setting up a full DR Region with an ALB and Auto Scaling group matching the primary region configuration is cost-inefficient. A more efficient solution involves using features like Aurora Global Databases for rapid failover.
Configuring a minimal Auto Scaling group in the DR region ensures the infrastructure is ready to scale up if needed during a failover, meeting the RTO and RPO requirements while keeping costs low.
Manual intervention during failover (launching a new ALB and Auto Scaling group) would exceed the RTO and RPO, which need to be automated for fast recovery.
As far as I’m aware, the answer is:
Configure the Aurora cluster to replicate data to the DR Region by using the Aurora global database option.
