Topic 1 Question 714
A company runs a highly available web application on Amazon EC2 instances behind an Application Load Balancer. The company uses Amazon CloudWatch metrics.
As the traffic to the web application increases, some EC2 instances become overloaded with many outstanding requests. The CloudWatch metrics show that the number of requests processed and the time to receive the responses from some EC2 instances are both higher compared to other EC2 instances. The company does not want new requests to be forwarded to the EC2 instances that are already overloaded.
Which solution will meet these requirements?
Use the round robin routing algorithm based on the RequestCountPerTarget and ActiveConnectionCount CloudWatch metrics.
Use the least outstanding requests algorithm based on the RequestCountPerTarget and ActiveConnectionCount CloudWatch metrics.
Use the round robin routing algorithm based on the RequestCount and TargetResponseTime CloudWatch metrics.
Use the least outstanding requests algorithm based on the RequestCount and TargetResponseTime CloudWatch metrics.

- 正解だと思う選択肢: B
Option B is correct because can use "RequestCountPerTarget" to identify the amount of requests for each EC2 instance. Then use "least outstanding requests algorithm" to route to targets with the lowest number of in progress requests.
Option D is wrong because "RequestCount" cannot identify the amount of requests for each EC2 instance. "RequestCount" is for the whole ALB.
