A database administrator wants to create a 500 GiB logical volume for a critical database. The system has four 200 GiB disks. The administrator wants both high performance and redundancy against disk failure. Which LVM configuration best meets these requirements?

Create a linear LV using all four disks.

Create a striped LV across all four disks with `-i 4`.

Create a RAID10-style LV by combining striping and mirroring with `-i 2 -m 1`.

Create a mirrored LV with `-m 1` using two disks for the mirror and two disks for the second mirror leg.

An administrator is investigating why a logical volume is not performing as expected. They want to see the physical extents that make up the LV and how they are distributed across the physical volumes. Which command provides this information?

`lvdisplay -m /dev/vgdata/lvdata`

`lvs -o +devices /dev/vgdata/lvdata`

`pvdisplay -m /dev/vgdata/lvdata`

What is the primary purpose of an LVM snapshot?

To increase the performance of a logical volume by caching reads.

To permanently duplicate all data to another physical volume.

To merge two logical volumes into one.

To create a point-in-time copy of a logical volume for backup or testing.

When a physical volume in a volume group fails, what is the typical symptom?

The logical volumes continue to work normally without any intervention.

The filesystem on the logical volume becomes read-only.

The volume group appears as 'incomplete' and logical volumes may be unavailable.

The volume group automatically reconfigures to use a spare disk.
