Question

A company is concerned that two NAT instances in use will no longer be able to support the traffic needed for the company’s application. A solutions architect wants to implement a solution that is highly available, fault tolerant, and automatically scalable. What should the solutions architect recommend?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Remove the two NAT instances and replace them with two NAT gateways in different Availability Zones. A NAT gateway lets private subnet resources reach the internet for outbound traffic only. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
