An application runs on Amazon EC2 instances in an Auto Scaling group. Following the deployment of a new feature on the EC2 instances, some instances were marked as unhealthy and then replaced by the Auto Scaling group. The EC2 instances terminated before a SysOps administrator could determine the cause of the health status changes. To troubleshoot this issue, the SysOps administrator wants to ensure that an AWS Lambda function is invoked in this situation.
How should the SysOps administrator meet these requirements?

  1. Activate the instance scale-in protection setting for the Auto Scaling group. Invoke the Lambda function through Amazon EventBridge (Amazon CloudWatch Events).
  2. Activate the instance scale-in protection setting for the Auto Scaling group. Invoke the Lambda function through Amazon Route 53.
  3. Add a lifecycle hook to the Auto Scaling group to invoke the Lambda function through Amazon EventBridge (Amazon CloudWatch Events).
  4. Add a lifecycle hook to the Auto Scaling group to invoke the Lambda function through Amazon Route 53.

  1. Create a tag-based resource group in AWS Resource Groups.
  2. Use AWS Trusted Advisor. Export the EC2 On-Demand Instances check results from Trusted Advisor.

A company needs to upload gigabytes of files every day. The company need to achieve higher throughput and upload speeds to Amazon S3.

  2. Create an Amazon ElastiCache cluster and enable caching for the S3 bucket.
  3. Set up AWS Global Accelerator and configure it with the S3 bucket.
  4. Enable S3 Transfer Acceleration and use the acceleration endpoint when uploading files.

A SysOps administrator maintains the security and compliance of a company's AWS account. To ensure the company's Amazon EC2 instances are following company policy, a SysOps administrator wants to terminate any EC2 instance that do not contain a department tag. Noncompliant resources must be terminated in near-real time.
Which solution will meet these requirements?

  1. Create an AWS Config rule with the required-tags managed rule to identify noncompliant resources. Configure automatic remediation to run the AWS- TerminateEC2Instance automation document to terminate noncompliant resources.
  2. Create a new Amazon EventBridge (Amazon CloudWatch Events) rule to monitor when new EC2 instances are created. Send the event to a Simple Notification Service (Amazon SNS) topic for automatic remediation.
  3. Ensure all users who can create EC2 instances also have the permissions to use the ec2:CreateTags and ec2:DescribeTags actions. Change the instance's shutdown behavior to terminate.
  4. Ensure AWS Systems Manager Compliance is configured to manage the EC2 instances. Call the AWS-StopEC2Instances automation document to stop noncompliant resources.

Answer(s): A

the correct answer to q8 is b. explanation since the mule app has a dependency, it is necessary to include project modules and dependencies to make sure the app will run successfully on the runtime on any other machine. source code of the component that the mule app is dependent of does not need to be included in the exported jar file, because the source code is not being used while executing an app. compiled code is being used instead.
