This CKS practice question tests your understanding of system hardening. 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.
Which TWO of the following are valid methods to apply a seccomp profile to a Kubernetes pod? (Select two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Using the pod annotation: seccomp.security.alpha.kubernetes.io/pod
Option B is correct because the seccomp.security.alpha.kubernetes.io/pod annotation was the original method to apply a seccomp profile to an entire pod in Kubernetes versions prior to v1.19. This annotation specifies the seccomp profile path or type (e.g., 'runtime/default' or 'localhost/<profile>') for the pod's containers, and it remains valid in older clusters or when using legacy configurations.
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.
✗
Using the field: spec.seccompProfile
Why it's wrong here
seccompProfile is under securityContext, not directly under spec.
✓
Using the pod annotation: seccomp.security.alpha.kubernetes.io/pod
Why this is correct
This deprecated annotation can still be used to apply seccomp profiles.

✓
Using the field: securityContext.seccompProfile.type
Why this is correct
The modern approach is to use securityContext.seccompProfile in the container spec.

✗
Using the command line flag: --seccomp-profile when running kubectl run
Why it's wrong here
kubectl run does not have a --seccomp-profile flag; seccomp is configured in the pod manifest.
✗
Using the pod annotation: container.seccomp.security.alpha.kubernetes.io
Why it's wrong here
This annotation does not exist for seccomp; the correct annotation is for AppArmor.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CNCF often tests the distinction between the GA field (securityContext.seccompProfile) and the deprecated annotation method, and candidates may confuse the incomplete annotation format (e.g., missing container name) with a valid option.
Detailed technical explanation
How to think about this question
Seccomp profiles in Kubernetes are applied via the securityContext.seccompProfile field (GA since v1.19) or via legacy annotations (alpha in v1.19, deprecated in v1.22). The field supports three types: RuntimeDefault (uses the container runtime's default seccomp profile), Localhost (points to a profile file on the node), and Unconfined (disables seccomp). The annotation method uses the format seccomp.security.alpha.kubernetes.io/pod for the pod level and container.seccomp.security.alpha.kubernetes.io/<container-name> for individual containers, with values like 'runtime/default' or 'localhost/<profile-path>'.
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.

What is the correct answer to this question?
The correct answer is: Using the pod annotation: seccomp.security.alpha.kubernetes.io/pod — Option B is correct because the seccomp.security.alpha.kubernetes.io/pod annotation was the original method to apply a seccomp profile to an entire pod in Kubernetes versions prior to v1.19. This annotation specifies the seccomp profile path or type (e.g., 'runtime/default' or 'localhost/<profile>') for the pod's containers, and it remains valid in older clusters or when using legacy configurations.
