An Application Load Balancer for a county tax portal uses shallow TCP health checks. Instances that accept TCP but return application errors remain in service, causing intermittent citizen failures. Which HA improvement best fixes detection?
Select an answer to reveal the explanation.
Short Explanation
A door that opens is not the same as a clerk who can help. TCP-only checks keep broken app hosts in the tax portal rotation—switch to real HTTP checks on a path that proves the app works.
Full Explanation
High availability depends on health checks that reflect application readiness. HTTP(S) checks against a meaningful endpoint remove hosts that pass TCP but fail the tax application. Disabling checks or checking unrelated IAM/laptop signals leaves failed targets in rotation and prolongs citizen errors.
