This ACE practice question tests your understanding of a team deploys an application on gke and needs it…. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A team deploys an application on GKE and needs it to be accessible at https://api.company.com with automatic TLS certificate provisioning. They use a Global external Application Load Balancer. What handles the TLS certificate?

A team deploys an application on GKE and needs it to be accessible at https://api.company.com with automatic TLS certificate provisioning. They use a Global external Application Load Balancer. What handles the TLS certificate?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

The GKE cluster automatically generates a self-signed TLS certificate for the domain

GKE clusters don't automatically provision trusted TLS certificates for custom domains — that's the load balancer's responsibility.

B

Best answer

A Google-managed SSL certificate attached to the load balancer's HTTPS target proxy

Google-managed SSL certificates are provisioned automatically and renewed before expiry. They're attached to the load balancer's target HTTPS proxy — zero manual certificate management.

C

Distractor review

Cloud DNS automatically provisions a TLS certificate when a domain is added

Cloud DNS manages DNS records — it doesn't provision TLS certificates. Certificates are managed at the load balancer.

D

Distractor review

cert-manager in GKE automatically obtains Let's Encrypt certificates for the Ingress

cert-manager with Let's Encrypt is a valid alternative but requires installing and managing cert-manager in the cluster. Google-managed certificates are the native GCP approach requiring no cluster-side tooling.

Common exam trap

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Technical deep dive

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

FAQ

Questions learners often ask

What does this ACE question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: A Google-managed SSL certificate attached to the load balancer's HTTPS target proxy — Google-managed SSL certificates, configured on the load balancer's target HTTPS proxy, provide automatic certificate provisioning and renewal. The certificate is issued once DNS is pointing to the load balancer IP. This eliminates manual certificate management entirely.

What should I do if I get this ACE question wrong?

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related ACE NAT questions on configuration and troubleshooting.
