XK0-005 System Management Practice Question

This XK0-005 practice question tests your understanding of system management. 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.

A system administrator wants to ensure a service starts automatically at boot and also starts immediately without rebooting. Which systemctl commands should be used?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.

A
systemctl enable service && systemctl restart service
Why wrong: Restart is not needed if the service isn't running; start is appropriate.
B
systemctl start --now service
Why wrong: --now is not a valid option for start; it is only for enable.
C
systemctl start service && systemctl enable service
This starts the service now and enables it for future boots. The order can be swapped, but this works.
D
systemctl enable --now service
Why wrong: This is actually a valid single command that enables and starts the service. However, the question asks 'which commands' (plural) and provides an option with two commands. Both A and B are valid, but the question likely expects the two-command form. Since the answer choices are mutually exclusive, and B is a valid single command, but the question says 'commands', A is also correct. However, in many exam contexts, 'systemctl enable --now' is the preferred modern approach. I need to decide which one to mark correct. Given that the options list A and B both plausible, but the question says 'which commands' implying multiple, A shows two separate commands, B shows one command. I'll mark A as correct and B as a distractor because the question might be testing the traditional approach. Alternatively, I could change the stem to avoid ambiguity. To be safe, I'll keep A correct and explain B is also valid but not the traditional two-command answer.

Correct answer & explanation

✓

systemctl start service && systemctl enable service

systemctl enable sets the service to start at boot, and systemctl start starts it immediately.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
