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 command loads an AppArmor profile from a file into the kernel?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
apparmor_load /path/to/profile
Why wrong: This command does not exist.
apparmor_parser -r /path/to/profile
This command loads or replaces an AppArmor profile.
aa-status
Why wrong: aa-status displays the status of loaded profiles, not load them.
aa-enforce /path/to/profile
Why wrong: aa-enforce sets a loaded profile to enforce mode, but does not load it.
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 -r /path/to/profile
The 'apparmor_parser' command is used to load AppArmor profiles into the kernel. Option A is correct. Options B, C, and D are not valid commands for loading AppArmor profiles.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
apparmor_load /path/to/profile
Why it's wrong here
This command does not exist.
apparmor_parser -r /path/to/profile
Why this is correct
This command loads or replaces an AppArmor profile.
Clue confirmation
The clue word "which command" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
aa-status
Why it's wrong here
aa-status displays the status of loaded profiles, not load them.
aa-enforce /path/to/profile
Why it's wrong here
aa-enforce sets a loaded profile to enforce mode, but does not load it.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
This command does not exist.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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 to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CKS NAT questions on configuration and troubleshooting.
