Which solution meets these requirements?

  • A. Provision a NAT instance in a public subnet. Modify each private subnet's route table with a default route that points to the NAT instance.
  • B. Provision a NAT instance in a private subnet. Modify each private subnet's route table with a default route that points to the NAT instance.
  • C. Provision a NAT gateway in a public subnet. Modify each private subnet's route table with a default route that points to the NAT gateway.

"The company needs a managed solution that minimizes operational maintenance" Watch out for NAT instances vs NAT Gateways. As the company needs a managed solution that minimizes operational maintenance - NAT Gateway is a public subnet is the answer.

Selected Answer: C
This meets the requirements for a managed, low maintenance solution for private subnets to access the internet: NAT gateway provides automatic scaling, high availability, and fully managed service without admin overhead. Placing the NAT gateway in a public subnet with proper routes allows private instances to use it for internet access. Minimal operational maintenance compared to NAT instances.

No good: NAT instances (A, B) require more hands-on management. Placing a NAT gateway in a private subnet (D) would not allow internet access.
