- A
All Kubernetes resources are namespaced
Why wrong: Some resources like nodes, PersistentVolumes, and namespaces themselves are cluster-scoped.
- B
Namespaces provide network isolation by default
Why wrong: Namespaces do not inherently provide network isolation; NetworkPolicies are needed for that.
- C
Resource quotas can be applied to a namespace to limit resource usage
ResourceQuotas can be set per namespace to control aggregate resource consumption.
- D
Namespaces can be used to separate environments like dev and prod
Namespaces are often used to logically separate environments.
- E
Deleting a namespace automatically deletes all resources in it, including cluster-scoped resources
Why wrong: Deleting a namespace only deletes resources within that namespace, not cluster-scoped resources like nodes.
KCNA Kubernetes Fundamentals Practice Question
This KCNA practice question tests your understanding of kubernetes fundamentals. 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.
Which TWO statements are true about Kubernetes namespaces? (Select 2)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Resource quotas can be applied to a namespace to limit resource usage
Namespaces provide logical isolation and are used to divide cluster resources among multiple users or teams. Some resources, like nodes and PersistentVolumes, are cluster-scoped and not namespaced.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

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 KCNA 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.
