AWS Certified SysOps Administrator - Associate SOA-C02 — Topic 1 Question 294

Question

A company runs an application on hundreds of Amazon EC2 instances in three Availability Zones. The application calls a third-party API over the public internet. A SysOps administrator must provide the third party with a list of static IP addresses so that the third party can allow traffic from the application. Which solution will meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Add a NAT gateway in the public subnet of each Availability Zone. Make the NAT gateway the default route of all private subnets in those Availability Zones. A NAT gateway lets private subnet resources reach the internet for outbound traffic only.
