ACE Practice Question: Microservices in a GKE cluster need to discover…
This ACE practice question tests your understanding of microservices in a gke cluster need to discover…. 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.
Microservices in a GKE cluster need to discover each other by name without using public DNS. Service A calls Service B at `http://service-b.production.svc.cluster.local`. Which GCP/Kubernetes feature provides this internal DNS resolution?
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
Best answer
Kubernetes cluster DNS (CoreDNS) resolving Service names within the cluster
CoreDNS (the default in-cluster DNS server) automatically creates records for every Service in the format `[service].[namespace].svc.cluster.local`, enabling service-to-service discovery.
B
Distractor review
Anthos Service Mesh — required for service-to-service DNS
Anthos Service Mesh adds observability, traffic management, and mTLS — in-cluster DNS resolution works without it, built into standard Kubernetes.
C
Distractor review
A custom /etc/hosts entry on each Pod
Manually managing /etc/hosts in Pods is impractical and doesn't scale — Kubernetes CoreDNS handles this automatically.
D
Distractor review
Cloud DNS private zone configured for the cluster's namespace
Cloud DNS private zones are GCP-level DNS — they're not the source of in-cluster `svc.cluster.local` resolution, which is handled by the cluster's CoreDNS.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

FAQ
Questions learners often ask
What does this ACE question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Kubernetes cluster DNS (CoreDNS) resolving Service names within the cluster — Kubernetes kube-dns (or CoreDNS) provides in-cluster DNS resolution. Every Service gets a DNS name in the format `[SERVICE].[NAMESPACE].svc.cluster.local`. This is managed automatically by Kubernetes and requires no external DNS configuration.
What should I do if I get this ACE question wrong?
Identify which ACE exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
