An EC2 Auto Scaling group spans two Availability Zones behind an ALB. An instance passes EC2 status checks, but its application is hung and ALB marks it unhealthy. The group uses only EC2 health checks and does not replace it. Which changes enable appropriate application-level replacement? Select 2 answers.

1. Disable the ALB target health checks and rely exclusively on the EC2 running state.
2. Enable Elastic Load Balancing health checks for the Auto Scaling group.
3. Configure an appropriate health-check grace period for the application startup time.
4. Change the ALB routing algorithm so that it also terminates unhealthy EC2 instances.
5. Increase the Auto Scaling maximum capacity but keep the group configured for EC2-only health checks.
