How will you automate the monitoring and repair of the system status check failure in an AWS environment?

One of your EC2 instances is reporting an unhealthy system status check. The operations team is looking for an easier way to monitor and repair these instances instead of fixing them manually .

How will you automate the monitoring and repair of the system status check failure in an AWS environment?
A . Write a python script that queries the EC2 API for each instance status check
B . Create CloudWatch alarms that stop and start the instance based on status check alarms.
C . Write a shell script that periodically shuts down and starts instances based on certain stats.
D . Buy and implement a third party monitoring tool.

Answer: B

Explanation:

Using Amazon CloudWatch alarm actions, you can create alarms that automatically stop, terminate, reboot, or recover your EC2 instances. You can use the stop or terminate actions to help you save money when you no longer need an instance to be running. You can use the reboot and recover actions to automatically reboot those instances or recover them onto new hardware if a system impairment occurs.

Writing a python script that queries the EC2 API for each instance status check, writing a shell script that periodically shuts down and starts instances based on certain stats, and buying and implementing a third party monitoring tool are all incorrect because it is unnecessary to go through such lengths when CloudWatch Alarms already has such a feature for you, offered at a low cost.
