Refer to the exhibit. A storage administrator needs to create a new filesystem of size 1.5 GiB on the available free space in volume group vg_data. Which command should be used?
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.

A
lvcreate -L 1.5G -n lv_new vg_data
Correct. This creates a 1.5 GiB logical volume named lv_new in vg_data.
B
lvcreate -l 1.5G -n lv_new vg_data
Why wrong: Incorrect. -l expects number of extents, not size.
C
lvcreate --size 1.5G --name lv_new vg_data
Why wrong: Incorrect. lvcreate uses -L and -n, not --size and --name.
D
lvcreate -L 1500M -n lv_new vg_data
Why wrong: Incorrect. 1500M is less than 1.5 GiB (1.5 GiB = 1536 MiB).
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
lvcreate -L 1.5G -n lv_new vg_data
The volume group vg_data has 1.99 GiB free space. To create a 1.5 GiB logical volume, use lvcreate with -L 1.5G -n lv_new vg_data. The -L option specifies size, -n specifies name.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
lvcreate -L 1.5G -n lv_new vg_data
Why this is correct
Correct. This creates a 1.5 GiB logical volume named lv_new in vg_data.

Incorrect. 1500M is less than 1.5 GiB (1.5 GiB = 1536 MiB).
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.
