AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An Ops team will launch a new VPC (10.0.0.0/16) spanning two Availability Zones. Each AZ will host one public and one private subnet. Resources in private subnets must initiate outbound internet connections even if one AZ becomes unavailable, and networking costs should be kept as low as AWS best practices allow. Which subnet and NAT configuration meets these requirements?

  • Create one NAT gateway in a public subnet of Availability Zone A and associate both private subnet route tables with this gateway.

  • Deploy a NAT gateway in each public subnet and configure each private subnet's route table to use the NAT gateway located in the same Availability Zone.

  • Launch a single NAT instance in one public subnet and update both private subnet route tables to forward 0.0.0.0/0 traffic to that instance.

  • Provision two NAT gateways in a dedicated services subnet located in Availability Zone A and point all private subnets to those gateways for internet access.
