Ultimate access to all questions.
A company operates a hybrid cloud setup with multiple AWS accounts organized under AWS Organizations. They require a solution to manage and maintain a version-controlled list of IPv4 addresses for on-premises hosts that are permitted to access AWS resources. The solution must also ensure this list is accessible to all AWS accounts within the organization.
Which solution meets these requirements?
A
Create a customer-managed prefix list. Add entries for the initial list of on-premises IPv4 hosts. Create a resource share in AWS Resource Access Manager. Add the managed prefix list to the resource share. Share the resource with the organization.
B
Create a customer-managed prefix list. Add entries for the initial list of on-premises IPv4 hosts. Use AWS Firewall Manager to share the managed prefix list with the organization.
C
Create a security group. Add inbound rule entries for the initial list of on-premises IPv4 hosts. Create a resource share in AWS Resource Access Manager. Add the security group to the resource share. Share the resource with the organization.
D
Create an Amazon DynamoDB table. Add entries for the initial list of on-premises IPv4 hosts. Create an AWS Lambda function that assumes a role in each AWS account in the organization to authorize inbound rules on security groups based on entries from the DynamoDB table.
