ACE Practice Question: Your team is planning a GKE cluster for a…
This ACE practice question tests your understanding of your team is planning a gke cluster for a…. 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.
Your team is planning a GKE cluster for a microservices application. Some services process sensitive payment data and must run on dedicated nodes that no other workloads can access. The rest of the application can share nodes. How should you configure the cluster?
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
Use Kubernetes NetworkPolicy to restrict network access between payment pods and other pods.
NetworkPolicy controls network traffic between pods, not pod scheduling placement. It doesn't prevent other workloads from running on the same nodes as payment services.
B
Distractor review
Set resource requests and limits so payment services consume all resources on their nodes.
Resource requests/limits manage resource allocation, not scheduling isolation. Other pods could still be scheduled on the same nodes if resources appear available.
C
Best answer
Apply taints to the dedicated node pool and tolerations to payment service pod specs.
Taints prevent regular pods from being scheduled on payment nodes. Tolerations in payment pod specs allow scheduling there. This achieves workload isolation within a single cluster.
D
Distractor review
Use separate GKE clusters: one for payment services and one for everything else.
Separate clusters provide isolation but add significant operational overhead (two control planes, separate networking, separate upgrades) when taints/tolerations achieve the same within one cluster.
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: Apply taints to the dedicated node pool and tolerations to payment service pod specs. — Kubernetes taints and tolerations control which pods can be scheduled on which nodes. Adding a taint to dedicated node pool nodes (e.g., `payment=true:NoSchedule`) prevents regular pods from being scheduled there. Adding a corresponding toleration to payment service pods allows them to be scheduled on those nodes. Node selectors or node affinity can additionally ensure payment pods land specifically on tainted nodes.
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.
