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 kubectl command is used to check whether AppArmor is enabled and which profiles are loaded on a node?
kubectl get seccomp
Why wrong: This is for seccomp, not AppArmor.
kubectl get apparmor
Why wrong: There is no kubectl command for AppArmor. AppArmor is a node-level feature.
aa-status
Correct. aa-status shows AppArmor status and loaded profiles.
systemctl status apparmor
Why wrong: This shows if the AppArmor service is running, but does not list loaded profiles.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
aa-status
The `aa-status` command is a standard Linux utility that displays the status of AppArmor, including whether it is enabled and which profiles are loaded. Since AppArmor is a Linux Security Module (LSM) enforced at the node level, not a Kubernetes resource, you must use a node-level command like `aa-status` to check its status. This command directly queries the AppArmor module in the kernel and lists all loaded profiles.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
kubectl get seccomp
Why it's wrong here
This is for seccomp, not AppArmor.
kubectl get apparmor
Why it's wrong here
There is no kubectl command for AppArmor. AppArmor is a node-level feature.
aa-status
Why this is correct
Correct. aa-status shows AppArmor status and loaded profiles.
Related concept
Read the scenario before looking for a memorised answer.
systemctl status apparmor
Why it's wrong here
This shows if the AppArmor service is running, but does not list loaded profiles.
Common exam traps
The trap here is that candidates assume AppArmor can be managed like a Kubernetes resource using kubectl, but it is a node-level security module that must be checked with Linux-native commands, not Kubernetes API objects.
Trap categories for this question
Command / output trap
There is no kubectl command for AppArmor. AppArmor is a node-level feature.
Detailed technical explanation
AppArmor operates as a mandatory access control (MAC) system using Linux Security Modules (LSM), and its profiles are stored in `/etc/apparmor.d/`. The `aa-status` command reads from the kernel's AppArmor interface (via `/sys/kernel/security/apparmor/`) to report the current enforcement mode and loaded profiles. In Kubernetes, AppArmor is applied to pods using annotations like `container.apparmor.security.beta.kubernetes.io/<container_name>`, but the node must have the corresponding profile loaded for it to work; `aa-status` is the definitive way to verify this.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
