AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company runs web servers in private subnets across two Availability Zones in a single VPC. Each subnet has a NAT gateway in the same Availability Zone. The instances download hundreds of terabytes of data every month from Amazon S3 within the same AWS Region, and the NAT gateway data-processing charges dominate the network bill. The company wants to minimize ongoing network costs without sacrificing high availability or throughput. Which action will achieve this goal at the lowest cost?

  • Replace both NAT gateways with burstable t3.micro NAT instances configured in an Auto Scaling group.

  • Create a VPC gateway endpoint for Amazon S3 in the VPC and update each private subnet's route table to direct S3 traffic to the endpoint.

  • Provision an AWS Direct Connect public virtual interface to the Region and route S3 traffic over the connection.

  • Delete one NAT gateway and configure the remaining NAT gateway to serve both subnets, accepting cross-AZ traffic.
