ACE Practice Question: A gaming company's GKE cluster uses a mix of node…
This ACE practice question tests your understanding of a gaming company's gke cluster uses a mix of node…. 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 gaming company's GKE cluster uses a mix of node pools: a standard on-demand pool for stateful database pods, and a Spot VM pool for compute-intensive but fault-tolerant game simulation pods. The simulation pods occasionally get preempted. How should the Deployment be configured to route simulation pods to the Spot pool only?
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
Set requests.cpu and requests.memory to very high values — GKE will route them to Spot nodes
Resource requests determine scheduling fit — they don't route pods to specific node pool types.
B
Best answer
Add a nodeSelector: cloud.google.com/gke-spot: 'true' to the simulation Deployment spec
GKE automatically labels Spot VMs with `cloud.google.com/gke-spot: 'true'`. A nodeSelector with this label ensures simulation Pods are scheduled only on Spot nodes.
C
Distractor review
Set podAffinity to prefer nodes where Spot pods are running
podAffinity attracts pods to nodes based on other pods, not node type — it doesn't target Spot VM node pools.
D
Distractor review
Name the simulation Deployment with a 'spot-' prefix — GKE routes prefixed deployments to Spot pools
Deployment naming has no bearing on node pool selection in GKE.
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: Add a nodeSelector: cloud.google.com/gke-spot: 'true' to the simulation Deployment spec — Node selectors or node affinity rules using the `cloud.google.com/gke-spot` node label target Spot VM node pools. Setting a node selector on the simulation Deployment ensures its Pods are scheduled only on Spot nodes, leaving on-demand nodes for stateful workloads.
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.
