- A
Create physical volume (pvcreate), then volume group (vgcreate), then logical volume (lvcreate), then format with filesystem (mkfs), then mount.
This is the correct order because LVM requires initializing the disk as a physical volume first, then adding it to a volume group, then creating a logical volume from that group, then formatting it with a filesystem, and finally mounting it for use.
- B
Create volume group (vgcreate), then physical volume (pvcreate), then logical volume (lvcreate), then format, then mount.
Why wrong: This is incorrect because you cannot create a volume group before the physical volume exists. The volume group is a collection of physical volumes, so pvcreate must precede vgcreate.
- C
Create physical volume (pvcreate), then format (mkfs), then volume group (vgcreate), then logical volume (lvcreate), then mount.
Why wrong: This is incorrect because filesystem formatting should be done on the logical volume, not on the physical volume. Also, the volume group must be created before the logical volume.
- D
Create logical volume (lvcreate), then physical volume (pvcreate), then volume group (vgcreate), then format, then mount.
Why wrong: This is incorrect because the logical volume depends on the volume group, which depends on the physical volume. You cannot create a logical volume without first having a physical volume and a volume group.
LFCS Operation of Running Systems Practice Question
This LFCS practice question tests your understanding of operation of running 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.
Order the steps to set up a LVM logical volume from a new disk.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create physical volume (pvcreate), then volume group (vgcreate), then logical volume (lvcreate), then format with filesystem (mkfs), then mount.
The correct sequence for setting up an LVM logical volume from a new disk is: first create a physical volume (PV) using pvcreate, then create a volume group (VG) with vgcreate, then create a logical volume (LV) with lvcreate, then format the LV with a filesystem using mkfs, and finally mount it to a directory. This order ensures all dependencies are satisfied: the VG requires the PV, the LV requires the VG, and the filesystem requires the LV.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✓
Create physical volume (pvcreate), then volume group (vgcreate), then logical volume (lvcreate), then format with filesystem (mkfs), then mount.
Why this is correct
This is the correct order because LVM requires initializing the disk as a physical volume first, then adding it to a volume group, then creating a logical volume from that group, then formatting it with a filesystem, and finally mounting it for use.

- ✗
Create volume group (vgcreate), then physical volume (pvcreate), then logical volume (lvcreate), then format, then mount.
Why it's wrong here
This is incorrect because you cannot create a volume group before the physical volume exists. The volume group is a collection of physical volumes, so pvcreate must precede vgcreate.
- ✗
Create physical volume (pvcreate), then format (mkfs), then volume group (vgcreate), then logical volume (lvcreate), then mount.
Why it's wrong here
This is incorrect because filesystem formatting should be done on the logical volume, not on the physical volume. Also, the volume group must be created before the logical volume.
- ✗
Create logical volume (lvcreate), then physical volume (pvcreate), then volume group (vgcreate), then format, then mount.
Why it's wrong here
This is incorrect because the logical volume depends on the volume group, which depends on the physical volume. You cannot create a logical volume without first having a physical volume and a volume group.
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 LFCS 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.
