ACE Practice Question: Your GKE application's pods are being evicted…
This ACE practice question tests your understanding of your gke application's pods are being evicted…. 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 GKE application's pods are being evicted frequently during periods of high traffic. You notice that pods without resource requests are being evicted first. The nodes are running at ~85% memory utilization. What should you do to reduce pod eviction?
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
Enable cluster autoscaler to add nodes before memory pressure occurs.
Cluster autoscaler adds nodes when pods are unschedulable, not when pods are running but under memory pressure. It doesn't prevent eviction of running pods.
B
Best answer
Set memory requests and limits for all pods to match their actual memory usage.
Pods with requests are classified as Burstable (or Guaranteed if limits equal requests). These are evicted after BestEffort pods. Proper requests also help the scheduler distribute pods evenly, reducing node pressure.
C
Distractor review
Increase the node machine type to have more memory.
Larger nodes reduce pressure temporarily but don't fix the root cause: pods without requests still have BestEffort QoS and will be evicted first under any memory pressure.
D
Distractor review
Configure pod disruption budgets (PDBs) to prevent eviction.
PDBs protect against voluntary disruptions (like node drain), not kubelet-initiated evictions due to memory pressure. OOM-based evictions ignore PDBs.
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: Set memory requests and limits for all pods to match their actual memory usage. — Kubernetes Quality of Service (QoS) classes are determined by resource requests and limits. Pods without requests are classified as BestEffort — the first to be evicted when a node experiences memory pressure. Setting memory requests (and ideally limits) for all pods promotes them to Burstable or Guaranteed QoS, making them less likely to be evicted. Additionally, right-sizing requests to reflect actual usage reduces node pressure.
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.
