This CKS practice question tests your understanding of system hardening. 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 of the following are valid methods to apply a seccomp profile to a pod in Kubernetes?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Setting 'securityContext.seccompProfile.type' in the pod spec
Option A is correct because the `securityContext.seccompProfile.type` field in the pod spec is the current, stable method to apply a seccomp profile to a pod in Kubernetes (since v1.19). This field directly specifies the seccomp profile type (e.g., `RuntimeDefault`, `Localhost`, or `Unconfined`) at the container or pod level, and is the recommended approach in modern clusters.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CNCF often tests the distinction between deprecated/removed features (like PodSecurityPolicy) and current stable APIs, and the trap here is that candidates confuse the old annotation-based approach (`seccomp.security.alpha.kubernetes.io/pod`) with the modern `securityContext.seccompProfile.type` field, or mistake AppArmor annotations for seccomp annotations.
Detailed technical explanation
How to think about this question
Under the hood, seccomp profiles are loaded into the kernel via the `prctl()` system call, and Kubernetes uses the `seccomp` field in the container runtime spec (CRI) to instruct the runtime (e.g., containerd) to apply the profile. The `RuntimeDefault` profile, for example, uses the Docker/containerd default seccomp profile that blocks around 44 syscalls, balancing security and compatibility. A real-world scenario where this matters is when running untrusted workloads: using `Localhost` with a custom profile can block dangerous syscalls like `mount` or `clone` while allowing necessary ones like `read` and `write`.
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 practitioner preparing for the CKS 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.
