A SysOps administrator created an Amazon VPC with an IPv6 CIDR block, which requires access to the internet.However, access from the internet towards the VPC is prohibited.After adding and configuring the required components to the VPC, the administrator is unable to connect to any of the domains that reside on the internet.
What additional route destination rule should the administrator add to the route tables?
Route ::/0 traffic to a NAT gateway
Route ::/0 traffic to an internet gateway
Route 0.0.0.0/0 traffic to an egress-only internet gateway
Route ::/0 traffic to an egress-only internet gateway
Explanations:
NAT gateways do not support IPv6; they work only with IPv4 addresses.
An internet gateway allows bidirectional traffic, but the requirement is to prohibit inbound access.
0.0.0.0/0 is an IPv4 route, whereas the VPC is configured with an IPv6 CIDR block.
An egress-only internet gateway enables outbound IPv6 traffic while blocking inbound connections.
I categorize that the answer is:
Route ::/0 traffic to an egress-only internet gateway
