I agree B -> https://docs.aws.amazon.com/es_es/autoscaling/ec2/userguide/lifecycle-hooks.html

Agree with B. Lifecycle hooks seem to be a good fit.

B is correct

https://docs.aws.amazon.com/autoscaling/ec2/userguide/lifecycle-hooks.html

I agree with the answer is B. Read this - Amazon EC2 Auto Scaling offers the ability to add lifecycle hooks to your Auto Scaling groups. These hooks enable an Auto Scaling group to be aware of events in the Auto Scaling instance lifecycle, and then perform a custom action when the corresponding lifecycle event occurs. A lifecycle hook provides a specified amount of time (one hour by default) to complete the lifecycle action before the instance transitions to the next state. https://docs.aws.amazon.com/autoscaling/ec2/userguide/lifecycle-hooks.html

Ans is B The lifecycle hook puts the instance into a wait state (Pending:Wait) and then performs a custom action.

Answer is B: Analysis: A. Use a scheduled AWS Lambda function and execute a script remotely on all EC2 instances to send data to the audit system ( Note: You can't use Lambda as Configuration management tool ) C. Use an EC2 Auto Scaling launch configuration to execute a custom script through user data to send data to the audit system when instances are launched and terminated. ( With userdate we can execute commands on ec2 only on the creation time, we can't execute commands on instance using userdata while the instance is getting terminated ) D. D. Execute a custom script on the instance operating system to send data to the audit system. Configure the script to be executed by the EC2 Auto Scaling group when the instance starts and is terminated. ( You can't tell ASG to execute script on ec2 ).

For example, let's say that your newly launched instance completes its startup sequence and a lifecycle hook pauses the instance. While the instance is in a wait state, you can install or configure software on it, making sure that your instance is fully ready before it starts receiving traffic. For another example of the use of lifecycle hooks, let's say that when a scale-in event occurs, the terminating instance is first deregistered from the load balancer (if the Auto Scaling group is being used with Elastic Load Balancing). Then, a lifecycle hook pauses the instance before it is terminated. While the instance is in the wait state, you can, for example, connect to the instance and download logs or other data before the instance is fully terminated. https://docs.aws.amazon.com/autoscaling/ec2/userguide/lifecycle-hooks.html

Life cycle hooks are the way to go B for sure

it's B

B right

Ans is B

bbbbbbbb

Agree with B. Lifecycle hooks

answer B Lifecycle hooks allow you to control what happens when your Amazon EC2 instances are launched and terminated as you scale out and in. For example, you might download and install software when an instance is launching, and archive instance log files in Amazon Simple Storage Service (S3) when an instance is terminating.
