1.05.2Basic

Initialize the empty partition /dev/sdb1 as an LVM physical volume.

The target device has already been verified.

Which command is appropriate?

Hint 1: Focus on the requirement

Identify the command that initializes an unused block device as an LVM physical volume.

Hint 2: Key terms

Review the short partitioning and LVM definitions before comparing the choices.

pvcreate: Writes LVM metadata so a block device can be used as a PV.
LVM label: Metadata identifying a device as an LVM physical volume.
PV: The LVM layer that supplies space to a volume group.
Data-loss risk: The possibility of destroying existing signatures or data during initialization.

Incorrectlvcreate /dev/sdb1

Incorrect. lvcreate allocates an LV from a VG.

Use read-only inspection or a disposable disk when learning storage commands.
Partition and LVM writes can destroy data; verify the target before running them.

Foundation review

PV initialization is a write operation and must not be confused with pvs, which only reports status.

Verify the device with lsblk or equivalent before initialization.
