Which solution will meet these requirements?
A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files. A SysOps administrator sets up a new S3 bucket. DOC-EXAMPLE-BUCKET, to support a new workload. The new S3 bucket also receives regular uploads of large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing S3 buckets provide. What should the SysOps administrator do to remediate this issue?
The SysOps administrator must modify the AWS Config rule that deletes noncompliant SSH inbound rules to update the rule to allow SSH from specific trusted IP addresses instead.

Answers
C.

Create an AWS Lambda function that adds an IP set to the security group's inbound rule. Update the AWS Config rule to change the automatic remediation action to use the Lambda function.

D.

Create an AWS Lambda function that updates the security group's inbound rule with the IP addresses from the business units. Update the AWS Config rule to change the automatic remediation action to use the Lambda function.

Answers
D.

Create an AWS Lambda function that updates the security group's inbound rule with the IP addresses from the business units. Update the AWS Config rule to change the automatic remediation action to use the Lambda function.

Suggested answer: B

Explanation:

Using a Systems Manager Automation runbook is appropriate for managing security group rules within the AWS Config remediation framework. A runbook provides a reusable, automated solution that can update the security group rule based on an IP list.

Automation Runbook for Security Group Updates: A runbook can automate security group modifications, such as adding the trusted IP addresses specified by the business units.

AWS Config Integration: Config rules can be set to use this runbook for automatic remediation, ensuring that the rule is updated without deleting it, which aligns with the requirement for SSH access from specific IPs.

Lambda functions could work but would require additional customization and complexity, making the runbook a more manageable and scalable solution for this task.
