Question #: 79
Topic #: 8

A company has multiple VPCs with subnets that use IPv4. Traffic from the VPCs to the internet uses a NAT gateway. The company wants to transition to IPv6.

A network engineer creates multiple IPv6-only subnets in an existing testing VPC. The network engineer deploys a new Amazon EC2 instance that has an IPv6 address into one of the subnets. During testing, the network engineer discovers that the new EC2 instance is not able to communicate with an IPv4-only service through the internet. The network engineer needs to enable the IPv6 EC2 instance to communicate with the IPv4-only service.

Which solution will meet this requirement?


A.

Enable DNS64 for the IPv6-only subnets. Update the route tables for the IPv6-only subnets to send traffic through the NAT gateway.


B.

Enable NAT64 for the testing VPC. Reconfigure the existing NAT gateway to support IPv6.


C.

Enable DNS64 for the new EC2 instance. Create a new egress-only internet gateway that supports IPv6.


D.

Enable NAT64 for each route table. Create a new NAT gateway that supports both IPv4 and IPv6.
