Cost-Effective Testing of CloudWatch Alarm
Question
You are an AWS consultant of a certain company.
There is a concern that web applications' performance must be monitored because the festive season is approaching, and there might be high spikes in traffic to your applications.
So, you need an effective way to respond to this.
You want to test the CloudWatch alarm that you want to implement in this use case.
Which is the cost-effective way to achieve this test?

A. B. C. D.Correct Answer: C.
AWS mentions:
The SetAlarmState temporarily sets the state of an alarm for testing goals.
Option B is incorrect because a dry run helps if you have the required permission for an action without making the actual request.
Options A and D are distractors.
They do not, in any way, correlate with the requirement of the question, which needs to test the alarm.

Option A: Do a temporary change to the alarm.
This option involves making a temporary change to the alarm configuration to trigger the alarm and test its behavior. This may not be the best option as it involves making a change to the production environment and may result in false alarms or missed alarms in the future.
Option B: Use AWS CLI Dry run.
This option involves using the AWS CLI Dry run feature to simulate the CloudWatch alarm action without actually triggering the alarm. This is a cost-effective and safe way to test the CloudWatch alarm as it does not affect the production environment.
Option C: Use AWS CLI set-alarm-state command.
This option involves using the AWS CLI set-alarm-state command to manually set the alarm state to either OK, ALARM, or INSUFFICIENT_DATA. This is a cost-effective way to test the CloudWatch alarm, but it may not accurately reflect the behavior of the alarm in a real-world scenario.
Option D: Set an EC2 fleet and increase the request rate to the web application until the alarm state is reached.
This option involves setting up an EC2 fleet and increasing the request rate to the web application until the alarm state is reached. This is not a cost-effective way to test the CloudWatch alarm as it involves setting up and running additional infrastructure, which can be expensive.
In conclusion, the most cost-effective and safest way to test the CloudWatch alarm in this use case is to use the AWS CLI Dry run feature.
