- A
edquota -u user
Why wrong: edquota edits quota limits for existing users but does not initialize the quota database; used for ext filesystems, not XFS.
- B
quotacheck -cug /mount
Why wrong: quotacheck scans filesystems and creates quota files for ext filesystems; not needed for XFS.
- C
xfs_quota -x -c 'limit -u bsoft=...' /mount
Correct. xfs_quota sets quota limits and is the proper tool for XFS quota management after mounting with quota options.
- D
quotaon /mount
Why wrong: quotaon enables quota enforcement for ext filesystems; XFS quotas are enabled at mount time, so quotaon is not applicable.
Question 412 of 537
How to Enable Quota Enforcement on an XFS Filesystem
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. A key principle to apply: xFS quotas. 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 enable disk quotas for users on an XFS filesystem. Which command initializes the quota database?
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.

Correct answer & explanation
✓
xfs_quota -x -c 'limit -u bsoft=...' /mount
On XFS filesystems, quotas are not stored in a separate database but are part of the filesystem metadata. The correct way to enable quotas is to mount the filesystem with the uquota or gquota options. Once mounted with quota options, the xfs_quota tool is used to manage quotas. The command 'xfs_quota -x -c 'limit -u bsoft=...' /mount' is a valid way to set quota limits, which effectively initializes the quota system for the filesystem. Options A and B are tools for non-XFS filesystems, and D (quotaon) is used for ext filesystems, not XFS.

Why it's wrong here
quotacheck scans filesystems and creates quota files for ext filesystems; not needed for XFS.
- ✓
xfs_quota -x -c 'limit -u bsoft=...' /mount
Why this is correct
Correct. xfs_quota sets quota limits and is the proper tool for XFS quota management after mounting with quota options.
Clue confirmation
The clue word "which command" in the question point toward this answer.

- ✗
quotaon /mount
Why it's wrong here
quotaon enables quota enforcement for ext filesystems; XFS quotas are enabled at mount time, so quotaon is not applicable.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Red Hat often tests the difference between ext4 and XFS quota management. For XFS, quotacheck and quotaon are not used; instead, quotas are enabled at mount time and managed with xfs_quota.
Detailed technical explanation
How to think about this question
XFS handles quotas differently from traditional ext filesystems: it stores quota limits and usage in the filesystem's internal metadata (in the quota inodes) rather than in separate files like aquota.user. To enable quotas on XFS, you must mount the filesystem with the `uquota` or `gquota` options (or use `pquota` for project quotas), which automatically initializes the quota tracking structures. The `xfs_quota` command is then used to set limits and view usage. In a real-world scenario, an administrator might forget to remount with quota options before running `xfs_quota`, resulting in an error that quotas are not enabled.

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. XFS quotas Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
