Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Virtual private gateway attached to the VPC and a customer gateway representing the on-premises router
To establish a Site-to-Site VPN, you need a virtual private gateway (VGW) or transit gateway on the AWS side, and a customer gateway (CGW) representing the on-premises router. Option C is correct. Option A is incorrect because a Direct Connect gateway is used for Direct Connect connections, not VPN. Option B is incorrect because an internet gateway is used for public internet traffic, not VPN. Option D is incorrect because a VPC endpoint is for private access to AWS services, not for establishing a VPN connection.
