You need a cost-effective disaster recovery plan for an application using EC2 instances behind an ALB in an Auto Scaling group, with an Aurora PostgreSQL database. RTO and RPO are both 15 minutes. Which combination of actions meets these targets at the lowest cost? (Choose two.)

The Aurora Global Database feature provides fast, low-latency cross-region replication, enabling an RPO of typically under 1 second and an RTO of under 1 minute for the database, easily meeting the 15-minute targets. Provisioning an ALB and Auto Scaling group in the DR region with a minimum, maximum, and desired capacity of 1 is a cost-effective warm standby strategy. This maintains a minimal presence to reduce recovery time while keeping costs low, as only one instance runs. At failover, the Auto Scaling group can be scaled up quickly. Configuring Aurora to export automated backups to the DR Region would result in an RPO much greater than 15 minutes, as restoration from backups takes significant time. Provisioning a full, mirrored environment in the DR Region (minimum, maximum, and desired capacity matching the primary) would be a hot standby, which is more expensive than necessary given the 15-minute RTO/RPO. Creating a new ALB and Auto Scaling group via CloudFormation at failover time would lead to an RTO significantly longer than 15 minutes due to the time required for provisioning and instance startup.
