Question 137

A SysOps administrator has created a VPC that contains a public subnet and a private subnet. Amazon EC2 instances that were launched in the private subnet cannot access the internet. The default network ACL is active on all subnets in the VPC, and all security groups allow all outbound traffic.

Which solution will provide the EC2 instances in the private subnet with access to the internet?

Create a NAT gateway in the public subnet. Create a route from the private subnet to the NAT gateway.

Create a NAT gateway in the public subnet. Create a route from the public subnet to the NAT gateway.

Create a NAT gateway in the private subnet. Create a route from the public subnet to the NAT gateway.

Create a NAT gateway in the private subnet. Create a route from the private subnet to the NAT gateway.

Correct Answer: A

To provide EC2 instances in the private subnet with access to the internet, you need to create a NAT gateway in the public subnet. This is because a NAT gateway needs to be in a public subnet where it can have a public IP address for internet connectivity. After creating the NAT gateway, you must then update the route table of the private subnet to route internet-bound traffic to the NAT gateway. This setup allows the instances in the private subnet to use the NAT gateway to reach the internet while preserving their private IP addresses.
