Looks good, but double-check the fstab syntax!

Nice, but I thought the default was ext4 nowadays?

Wait, why ext3? Isn't ext4 better for most cases?

Just a heads up, PE size is 16M, so 20 PE is 320M total.

I remember that we need to edit the /etc/fstab file to ensure the logical volume mounts automatically, but I’m unsure about the exact format for that line.

I believe the logical volume creation command is lvcreate, but I'm a bit confused about the syntax for specifying the size in PE.

I practiced a similar question where we had to set the size of the volume group, but I can't recall if we need to specify the size in the vgcreate command.

I think I remember that we need to create the physical volume first, but I'm not sure if the command is pvcreate or something else.

I'm pretty confident about this one. The principle of full disclosure means that any material deviations from GAAP must be explained to the readers of the financial information, so the answer is A.
