Sysops Exam Question Issue

[Steve Stonebraker]

On the SysOps exam I think the answer I selected is correct per what I highlighted in the screenshot. I don’t understand why it is wrong.

Thanks Steve for raising this issue. Please take note that there are two types of metrics:

1. Amazon EC2 CloudWatch metrics ( CPUUtilization, DiskReadBytes, NetworkIn etc..)

2. Auto Scaling Group metrics ( GroupInServiceInstances, GroupPendingInstances etc…)

Let’s look at the piece of documentation that you presented. It says:

“Amazon EC2 Auto Scaling publishes data points to CloudWatch about your Auto Scaling groups. The metrics are available at 1-minute granularity at no additional charge, but you must enable them. By doing this, you get continuous visibility into the operations of your Auto Scaling groups so that you can quickly respond to changes in your workloads. ”

Reference:

https://docs.aws.amazon.com/autoscaling/ec2/userguide/as-instance-monitoring.html

Please take note that this paragraph is referring to the Auto Scaling Group Metrics ( GroupInServiceInstances, GroupPendingInstances etc…) and not the Amazon EC2 CloudWatch metrics ( CPUUtilization, DiskReadBytes, NetworkIn etc..), which is being asked in the scenario.

The Auto Scaling Group metrics are available at 1-minute granularity at no charge, but not its underlying Amazon EC2 instance metrics.

Hope this clarifies.
