AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An operations team runs an HTTPS web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The ALB terminates TLS but currently forwards traffic to the instances over HTTP. A new compliance control requires encryption on every network hop and public certificates that renew automatically, while minimizing ongoing maintenance for the instances. Which solution meets the requirements with the LEAST operational effort?

  • Replace the ALB with a Network Load Balancer in TLS mode, import a public certificate on every EC2 instance, and configure cron jobs to renew and deploy the certificates.

  • Create a private CA in AWS Certificate Manager, issue private certificates to each instance, keep the ALB forwarding traffic over HTTP, and rely on ACM to rotate the private certificates.

  • Attach an ACM public certificate to the ALB HTTPS listener, change the target group protocol to HTTPS, keep the self-signed certificates on the instances, and allow the ALB to reach port 443 on the targets.

  • Install a Let's Encrypt certificate on each EC2 instance, change the ALB listener to TCP 443 for pass-through, and schedule certificate renewal scripts on every server.
