This CKA practice question tests your understanding of storage. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
An administrator wants to configure a StatefulSet with persistent storage using volumeClaimTemplates. Which THREE statements are correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The PVC names are generated as '<volumeClaimTemplate-name>-<statefulset-name>-<ordinal>'.
volumeClaimTemplates generate unique PVCs for each replica (A). The PVs are retained when scaling down (B). StatefulSet uses ordinal naming, and PVC names include the pod name (C). volumeClaimTemplates does not create a single shared PVC (D), and the reclaim policy is specified in the StorageClass or PV, not in the StatefulSet (E).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The PVC names are generated as '<volumeClaimTemplate-name>-<statefulset-name>-<ordinal>'.
Why this is correct
Kubernetes uses this naming convention for StatefulSet PVCs.
Related concept
Read the scenario before looking for a memorised answer.
✗
All replicas share the same PVC if volumeClaimTemplates is used.
Why it's wrong here
Each replica gets its own PVC; they do not share.
✓
When the StatefulSet is scaled down, the PVCs are not automatically deleted.
Why this is correct
PVCs are retained to preserve data, even if the pod is removed.
Related concept
Read the scenario before looking for a memorised answer.
✓
Each replica of the StatefulSet gets its own PVC created from the template.
Why this is correct
volumeClaimTemplates creates a separate PVC for each pod.
Related concept
Read the scenario before looking for a memorised answer.
✗
The reclaim policy for the volumes is defined in the volumeClaimTemplates.
Why it's wrong here
Reclaim policy is set on the StorageClass or PV, not in volumeClaimTemplates.
Common exam traps
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.
Detailed technical explanation
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.
Real-world example
How this comes up in practice
A practitioner preparing for the CKA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
