Which factors could cause this error?
(Choose two.)
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
Explanations:
VPC peering requires non-overlapping CIDR blocks. The CIDR blocks 10.10.0.0/16 and 10.10.10.0/24 overlap, causing the peering failure.
VPC peering supports connections across Regions, so VPCs do not need to be in the same Region for peering.
An Internet Gateway is not required for VPC peering; it is only necessary for public internet access.
AWS Resource Access Manager (RAM) is not needed to peer VPCs across accounts; RAM is used for sharing resources within or across accounts.
The IAM role in the peer accepter account needs specific permissions to accept the peering request; lacking permissions can cause the failure.
