A user has setup a CloudWatch alarm on an EC2 action when the CPU utilization is above 75%. The alarm sends
a notification to SNS on the alarm state. If the user wants to simulate the alarm action how can he achieve
this?

Run activities on the CPU such that its utilization reaches above 75%
B.

C.
The user can set the alarm state to ‘Alarm’ using CLI

Explanation:
Amazon CloudWatch alarms watch 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.The user can test an alarm by setting it to any state using the SetAlarmState API (mon-set-alarm-state
command.. This temporary state change lasts only until the next alarm comparison occurs.
