Question #1046
Which AWS services enable the establishment of a private network connection between VPCs located in separate AWS regions? (Choose two.)
VPC endpoints
Amazon Route 53
VPC peering
AWS Direct Connect
AWS Transit Gateway
Explanation
The correct answers are C (VPC peering) and E (AWS Transit Gateway).
- VPC Peering (C): Allows direct private connectivity between VPCs, including those in different AWS regions (inter-region VPC peering). Traffic stays within the AWS network and does not traverse the public internet.
- AWS Transit Gateway (E): Supports inter-region peering, enabling VPCs attached to Transit Gateways in separate regions to communicate privately.
Why other options are incorrect:
- A (VPC endpoints): Connects a VPC to AWS services privately, not VPC-to-VPC.
- B (Route 53): A DNS service for routing traffic but does not establish private network connections.
- D (Direct Connect): Establishes dedicated connections from on-premises to AWS, not directly between VPCs across regions.
Key Points:
- Use inter-region VPC peering for direct VPC-to-VPC connections across regions.
- Use Transit Gateway inter-region peering for scalable multi-region architectures involving multiple VPCs.
Answer
The correct answer is: CE
