An ALB service handles requests lasting up to two minutes. Planned target deregistration cuts them off after a short draining interval, even though instances remain running. Which control should be adjusted first?

1. Set an appropriate target deregistration delay and coordinate instance shutdown with draining.
2. Set deregistration delay to zero to maximize graceful draining.
3. Disable every application readiness check and leave the short delay unchanged.
4. Change only the DNS TTL of the application hostname.
