A user has created an Auto Scaling group using CLI. The user wants to enable CloudWatch detailed
monitoring for that group. How can the user configure this?

A.
When the user sets an alarm on the Auto Scaling group, it automatically enables detail monitoring

B.
By default detailed monitoring is enabled for Auto Scaling

C.
Auto Scaling does not support detailed monitoring

D.
Enable detail monitoring from the AWS console

Explanation:
CloudWatch is used to monitor AWS as well as the custom services. It provides either basic or detailed
monitoring for the supported AWS products. In basic monitoring, a service sends data points to CloudWatch
every five minutes, while in detailed monitoring a service sends data points to CloudWatch every minute. To
enable detailed instance monitoring for a new Auto Scaling group, the user does not need to take any extra
steps. When the user creates an Auto Scaling launch config as the first step for creating an Auto Scaling
group, each launch configuration contains a flag named InstanceMonitoring.Enabled. The default value of this
flag is true. Thus, the user does not need to set this flag if he wants detailed monitoring.
