This CKS practice question tests your understanding of system hardening. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 pod is in a Pending state with the event: 'failed to generate spec: failed to validate seccomp profile: seccomp profile not found'. The profile is stored at /var/lib/kubelet/seccomp/custom.json on the node. Which of the following is the MOST likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The localhostProfile field contains an absolute path instead of a relative one
The error 'seccomp profile not found' indicates the kubelet cannot locate the profile file. In Kubernetes, when using a seccomp profile stored on the node, the `localhostProfile` field must specify a relative path from the kubelet's seccomp root directory (default `/var/lib/kubelet/seccomp`). An absolute path like `/var/lib/kubelet/seccomp/custom.json` causes the kubelet to look for the file at that exact absolute path, but the seccomp validation logic expects a relative path and prepends the root, leading to a 'not found' error.
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 profile name is misspelled in the pod specification
Why it's wrong here
If misspelled, it would also cause 'not found', but the most common mistake is using absolute vs relative path.
✓
The localhostProfile field contains an absolute path instead of a relative one
Why this is correct
Correct. Kubernetes expects a relative path. Using an absolute path causes it to look for the file in an incorrect location.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
The node does not have seccomp enabled in the kubelet
Why it's wrong here
If seccomp were disabled, the error would be different, likely about unsupported feature.
✗
The seccomp profile JSON is malformed
Why it's wrong here
If the JSON were malformed, the error would likely mention parsing failure, not 'profile not found'.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CNCF often tests the nuance that `localhostProfile` requires a relative path, not an absolute one, and candidates mistakenly think any valid filesystem path works or confuse this with container runtime seccomp paths.
Detailed technical explanation
How to think about this question
Under the hood, the kubelet's seccomp validation resolves `localhostProfile` by joining the kubelet's `--seccomp-default-profile-root` (default `/var/lib/kubelet/seccomp`) with the provided path. If the path is absolute, the join operation may fail or produce an incorrect lookup path, depending on the implementation. In real-world scenarios, this is a common misconfiguration when migrating from older Kubernetes versions or copying examples that use absolute paths, and the fix is to use a relative path like `custom.json`.
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.
TExam Day Tips
→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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
