What will be the status of the alarms on the EBS volume?

A user has setup an EBS backed instance and attached 2 EBS volumes to it. The user has setup
a CloudWatch alarm on each volume for the disk data. The user has stopped the EC2 instance and
detached the EBS volumes. What will be the status of the alarms on the EBS volume?

A.
OK

B.
Insufficient Data

C.
Alarm

D.
The EBS cannot be detached until all the alarms are removed

Explanation:
Amazon CloudWatch alarm watches a single metric over a time period that the user specifies and
performs one or more actions based on the value of the metric relative to a given threshold over a
number of time periods. Alarms invoke actions only for sustained state changes. There are three
states of the alarm: OK, Alarm and Insufficient data. In this case since the EBS is detached and
inactive the state will be Insufficient.
