EX200 Create and configure file systems Practice Question
This EX200 practice question tests your understanding of create and configure file 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 has an XFS filesystem on a logical volume /dev/vg_data/lv_data mounted at /data. To extend the filesystem by 10GB, which sequence of commands is correct?
Option D is correct because for XFS filesystems, the logical volume must be extended first with `lvextend`, then the filesystem must be grown online using `xfs_growfs` with the mount point as the argument. XFS does not support shrinking and requires this specific order; `resize2fs` is only for ext2/3/4 filesystems.
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.
First extend the logical volume, then grow the XFS filesystem.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Red Hat often tests the misconception that `resize2fs` works for all filesystem types, or that the order of operations (extend LV vs. grow filesystem) is interchangeable, leading candidates to choose options that use the wrong tool or reverse the sequence.
Detailed technical explanation
How to think about this question
XFS uses `xfs_growfs` to expand the filesystem to fill the available space in the underlying block device; it can be run online without unmounting. The `lvextend` command modifies the logical volume's size, and `xfs_growfs` reads the new size from the device. In contrast, ext4 uses `resize2fs` which can be run after `lvextend` and supports both growing and shrinking (though shrinking is risky).
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.

What is the correct answer to this question?
The correct answer is: lvextend -L +10G /dev/vg_data/lv_data; xfs_growfs /data — Option D is correct because for XFS filesystems, the logical volume must be extended first with `lvextend`, then the filesystem must be grown online using `xfs_growfs` with the mount point as the argument. XFS does not support shrinking and requires this specific order; `resize2fs` is only for ext2/3/4 filesystems.
