EX200 Deploy, configure, and maintain systems Practice Question
This EX200 practice question tests your understanding of deploy, configure, and maintain systems. 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.
An administrator wants to change the default systemd target to multi-user.target. Which three steps are part of a correct procedure? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
systemctl isolate multi-user.target
Option C is correct because `systemctl isolate multi-user.target` immediately switches the current systemd target to multi-user.target, which is the correct way to change the active target at runtime without a reboot. This command stops all units not required by the new target and starts those that are, effectively changing the system's operational state.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
systemctl enable multi-user.target
Why it's wrong here
Not needed; targets are enabled by setting default.
✗
systemctl start multi-user.target
Why it's wrong here
systemctl start is for services; targets use isolate or set-default.
✓
systemctl isolate multi-user.target
Why this is correct
Changes the current target immediately (part of procedure).

✓

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse `systemctl enable` (which controls whether a unit starts at boot) with `systemctl set-default` (which sets the default target for boot), and they may think `systemctl start` is sufficient to change the active target, not realizing that `isolate` is required to properly transition systemd to a different target.
Detailed technical explanation
How to think about this question
Under the hood, systemd uses target units to represent system states (runlevels). The `isolate` command stops all units not part of the specified target and its dependencies, ensuring a clean transition. The `set-default` command modifies the symlink at `/etc/systemd/system/default.target` to point to the desired target, which is read at boot; alternatively, manually creating this symlink with `ln -sf` achieves the same effect. In real-world scenarios, administrators often use `systemctl isolate` for immediate maintenance mode changes (e.g., switching to rescue.target) and `set-default` for persistent boot configuration.
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 EX200 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.
