The Security Team Depends on AWS CloudTrail to Detect Sensitive

question 49

Multiple Choice

The Security team depends on AWS CloudTrail to detect sensitive security issues in the company's AWS account. The DevOps Engineer needs a solution to auto-remediate CloudTrail being turned off in an AWS account. What solution ensures the LEAST amount of downtime for the CloudTrail log deliveries?

• A) Create an Amazon CloudWatch Events rule for the CloudTrail StopLogging event. Create an AWS Lambda function that uses the AWS SDK to call StartLogging on the ARN of the resource in which StopLogging was called. Add the Lambda function ARN as a target to the CloudWatch Events rule.
• B) Deploy the AWS-managed CloudTrail-enabled AWS Config rule, set with a periodic interval of 1 hour. Create an Amazon CloudWatch Events rule for AWS Config rules compliance change. Create an AWS Lambda function that uses the AWS SDK to call StartLogging on the ARN of the resource in which StopLogging was called. Add the Lambda function ARN as a target to the CloudWatch Events rule.
• C) Create an Amazon CloudWatch Events rule for a scheduled event every 5 minutes. Create an AWS Lambda function that uses the AWS SDK to call StartLogging on an CloudTrail trail in the AWS account. Add the Lambda function ARN as a target to the CloudWatch Events rule.
• D) Launch a t2.nano instance with a script running every 5 minutes that uses the AWS SDK to query CloudTrail in the current account. If the CloudTrail trail is disabled, have the script re-enable the trail.
