Question #: 738
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

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? (Choose two.)

  • A. The IPv4 CIDR ranges of the two VPCs overlap
  • B. The VPCs are not in the same Region
  • C. One or both accounts do not have access to an Internet gateway
  • D. One of the VPCs was not shared through AWS Resource Access Manager
  • E. The IAM role in the peer accepter account does not have the correct permissions
