This EX200 practice question tests your understanding of configure local storage. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Exhibit
# parted /dev/sdc print
Model: VMware Virtual disk (scsi)
Disk /dev/sdc: 2147MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 2147MB 2146MB xfs primary
# mount /dev/sdc1 /mnt
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error.
Refer to the exhibit. An administrator attempts to mount the partition but receives an error. Which command should be run first to resolve the issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
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.

A
xfs_repair /dev/sdc1
Why wrong: xfs_repair is for repairing XFS filesystems, but the error might be due to no filesystem at all.
B
file -s /dev/sdc1
The file command checks the actual filesystem type; the partition table shows xfs but maybe it's not created yet.
C
partprobe /dev/sdc
Why wrong: partprobe updates the kernel partition table; not relevant to filesystem type mismatch.
D
mkfs.xfs /dev/sdc1
Why wrong: Creating a new filesystem would destroy data; troubleshooting should start with checking the filesystem.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
file -s /dev/sdc1
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
xfs_repair /dev/sdc1
Why it's wrong here
xfs_repair is for repairing XFS filesystems, but the error might be due to no filesystem at all.
✓
file -s /dev/sdc1
Why this is correct
The file command checks the actual filesystem type; the partition table shows xfs but maybe it's not created yet.
Clue confirmation
The clue words "first", "which command" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
