AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company connects its production VPC (10.0.0.0/16) to the on-premises network (10.1.0.0/16) through an AWS Transit Gateway and a Site-to-Site VPN attachment. Subnet routes in the VPC point 10.1.0.0/16 to the transit gateway, but the transit gateway route table lists only the VPC CIDR. EC2 instances cannot reach on-premises servers. What change will restore connectivity securely?

  • Deploy a NAT gateway in each private subnet and route traffic to the NAT gateway instead of the transit gateway.

  • Add a 0.0.0.0/0 static route in the transit gateway route table that targets the VPN attachment.

  • Change the VPC subnet route so that 10.1.0.0/16 targets the virtual private gateway used by the VPN.

  • Enable route propagation from the Site-to-Site VPN attachment to the transit gateway route table.
