Topic 1 Question 128
2 つ選択A software company hosts an application on AWS with resources in multiple AWS accounts and Regions. The application runs on a group of Amazon EC2 instances in an application VPC located in the us-east-1 Region with an IPv4 CIDR block of 10.10.0.0/16. In a different AWS account, a shared services VPC is located in the us-east-2 Region with an IPv4 CIDR block of 10.10.10.0/24. When a cloud engineer uses AWS CloudFormation to attempt to peer the application VPC with the shared services VPC, an error message indicates a peering failure.
Which factors could cause this error?
The IPv4 CIDR ranges of the two VPCs overlap
The VPCs are not in the same Region
One or both accounts do not have access to an Internet gateway
One of the VPCs was not shared through AWS Resource Access Manager
The IAM role in the peer accepter account does not have the correct permissions

FYI, Other reasons for issue : If the IAM role in the accepter account doesn't have the right permissions
If the PeerRoleArn property isn't passed correctly when you create a VPC peering connection between VPCs in different accounts
If the PeerRegion property isn't passed correctly when you're creating a VPC peering connection between VPCs in different AWS Regions
👍 3God_Is_Love2023/03/08 AE is correct D is not correct because you cannot share VPC via RAM, subnet can
