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 of the following is the correct command to load an AppArmor profile from a file named 'my-profile'?
apparmor_load my-profile
Why wrong: This command does not exist.
apparmor_parser my-profile
Correct. apparmor_parser loads the profile.
apparmor_parser -R my-profile
Why wrong: -R removes a profile, not loads it.
systemctl start apparmor my-profile
Why wrong: systemctl starts the AppArmor service, not a specific profile.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
apparmor_parser my-profile
The correct command to load an AppArmor profile from a file is `apparmor_parser my-profile`. The `apparmor_parser` tool is used to load, replace, or remove AppArmor profiles into the kernel. When invoked without flags, it loads the profile from the specified file into the kernel's AppArmor security module, enforcing the defined access controls.
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.
apparmor_load my-profile
Why it's wrong here
This command does not exist.
apparmor_parser my-profile
Why this is correct
Correct. apparmor_parser loads the profile.
Related concept
Read the scenario before looking for a memorised answer.
apparmor_parser -R my-profile
Why it's wrong here
-R removes a profile, not loads it.
systemctl start apparmor my-profile
Why it's wrong here
systemctl starts the AppArmor service, not a specific profile.
Common exam traps
The trap here is that candidates confuse `apparmor_parser` with a hypothetical `apparmor_load` command or misuse the `-R` flag, thinking it stands for 'run' or 'reload' instead of 'remove'.
Trap categories for this question
Command / output trap
This command does not exist.
Detailed technical explanation
Under the hood, `apparmor_parser` compiles the human-readable profile into a binary format and writes it to the kernel's securityfs via `/sys/kernel/security/apparmor/.load`. The `-R` flag instead writes to the `.remove` file to unload the profile. In a real-world Kubernetes scenario, AppArmor profiles are often loaded on each node before starting pods, and using `-R` by mistake could disable critical security policies, leaving containers unrestricted.
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.
