Alibaba Cloud Certified Associate – Cloud Computing — Question 17

Server Load Balancer supports health checks for ECS instances and allows user to specify the frequency. If an ECS instance does not qualify the health check, traffic will not be forwarded to that instance, thereby ensuring application availability.

Answer options

• A. TRUE
• B. FALSE

Correct answer: A

Explanation

The correct answer is TRUE because the Server Load Balancer indeed supports health checks that prevent traffic from being sent to unhealthy ECS instances, ensuring application availability. The option FALSE is incorrect as it contradicts the described functionality of the load balancer.
