AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An e-commerce company operates a VPC with two public and two private subnets split between eu-west-1a and eu-west-1b. Instances located in the private subnet in eu-west-1a cannot download operating-system updates from the internet. A NAT gateway was created in a public subnet in eu-west-1b, and the private subnet's route table sends 0.0.0.0/0 traffic to that gateway. Which action will restore internet access while following AWS best practices and making the fewest possible changes?

  • Associate the private subnet with a route table that already has a 0.0.0.0/0 route pointing to the internet gateway.

  • Create a NAT gateway in a public subnet in eu-west-1a and update the private subnet's default route to use this new gateway.

  • Modify the security group of the instances to allow outbound TCP 443 traffic to 0.0.0.0/0.

  • Attach a second Elastic IP address to the existing NAT gateway to increase throughput and retry the update.
