AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company runs a two-tier application in a VPC (CIDR 10.20.0.0/16). An internet gateway is attached. Web servers in a private subnet (10.20.101.0/24) need to download OS updates from the internet through a NAT gateway deployed in a public subnet. Security groups and network ACLs allow outbound HTTPS. The web servers still cannot reach the internet. What change will restore connectivity?

  • Add a 0.0.0.0/0 route in the private subnet's route table that targets the NAT gateway ID.

  • Enable auto-assign public IPv4 address on the private subnet and restart the web servers.

  • Create an interface VPC endpoint for Amazon S3 in the private subnet's route table.

  • Add an outbound 0.0.0.0/0 rule to the web servers' security group.
