A. B. C. D.Answer - A.
The AWS documentation mentions the following.
An egress-only Internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows outbound communication over IPv6 from instances in your VPC to the Internet, and prevents the Internet from initiating an IPv6 connection with your instances.
For more information on Egress only Internet gateways , please refer to the below link:
http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/egress-only-internet-gateway.htmlOutbound communication over IPv6 from instances in a VPC to the internet can be achieved using an Egress-only Internet Gateway (EIG). Therefore, the correct answer is A.
Let's take a closer look at each of the options:
A. Egress Only Internet Gateway: An EIG is a horizontally scaled VPC component that allows outbound communication over IPv6 from instances in a VPC to the internet. It provides a static, public IPv6 address for the VPC and does not allow inbound traffic. An EIG can be created in a VPC with an IPv6 CIDR block and does not require any special configuration on the instances themselves.
B. Customer Gateway: A customer gateway is a physical device or software application on the customer's side of a site-to-site VPN connection. It is used to establish a secure connection between the customer's network and an Amazon VPC.
C. Virtual Private Gateway: A virtual private gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between an Amazon VPC and other networks via a site-to-site VPN connection. It provides a static, public IP address on the Amazon VPC side of the VPN connection.
D. Virtual Private Connection: A virtual private connection is a dedicated network connection between an Amazon VPC and an on-premises network. It is a physical connection that provides a direct link between the customer's network and the VPC.
In conclusion, an Egress-only Internet Gateway is the correct option for outbound communication over IPv6 from instances in a VPC to the internet.
