. If a server fails the health check, the load balancer takes the server temporarily out of rotation. If the server later passes the health check, the load balancer returns it to the rotation. https://docs.oracle.com/en-us/iaas/Content/Balance/Tasks/load_balancer_health_management.htm#HealthCheckManagement Ans D

D is correct. In https://docs.oracle.com/en-us/iaas/Content/Balance/Tasks/load_balancer_health_management.htm#HealthCheckManagement says: If a server fails the health check, the load balancer takes the server temporarily out of rotation. If the server later passes the health check, the load balancer returns it to the rotation.

If a server fails the health check, the load balancer takes the server temporarily out of rotation. It implies no request goes to that server which is down. Note that load balancer can not make changes to backend set. https://docs.cloud.oracle.com/en-us/iaas/Content/Balance/Tasks/editinghealthcheck.htm

Correct Answer is C: A health check is a test to confirm the availability of backend servers. A health check can be a request or a connection attempt. Based on a time interval you specify, the load balancer applies the health check policy to continuously monitor backend servers. If a server fails the health check, the load balancer takes the server temporarily out of rotation. If the server subsequently passes the health check, the load balancer returns it to the rotation. https://docs.cloud.oracle.com/en-us/iaas/Content/Balance/Tasks/editinghealthcheck.htm
