What is the primary purpose of an LVM snapshot?

To mirror data across multiple physical volumes for redundancy

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

To increase the size of a logical volume dynamically

To cache frequently accessed data on faster storage

A Linux engineer needs to ensure that a USB backup drive is always mounted with a specific set of permissions for the 'backup' group, regardless of which USB port it is plugged into. The drive is currently detected as /dev/sdb1, but the engineer wants to avoid relying on the device name. Which approach should the engineer use?

Create a udev rule that matches the device's serial number and sets GROUP="backup", MODE="0660".

Use the 'blkid' command to set the device's UUID and then mount it manually each time.

Configure the drive's filesystem with the 'setgid' bit so that all files inherit the 'backup' group.

Add an entry to /etc/fstab using /dev/sdb1 and the 'gid=backup' mount option.

A company uses LVM thin provisioning to provide storage for virtual machines. The thin pool is 1 TB, and the virtual disks are thinly provisioned. One VM is writing heavily and the thin pool is approaching full. The administrator needs to prevent the pool from filling up completely, which would cause all VMs to fail. Which action should the administrator take?

Create a snapshot of the thin pool to use as a backup.

Reduce the size of the thin pool to force the VM to stop writing.

Enable the 'snapshot_autoremove' option on the thin pool.

Set the 'thin_pool_autoextend_threshold' and 'thin_pool_autoextend_percent' options.
