An administrator needs to create a RAID10 logical volume using LVM. The volume group has four physical volumes. Which command should the administrator use to create a RAID10 logical volume named 'lvraid10' with a size of 100 GB?

lvcreate --type raid10 -L 100G -n lvraid10 vg

lvcreate --type raid1 -L 100G -n lvraid10 vg

mdadm --create /dev/md0 --level=10 --raid-devices=4 /dev/sdb /dev/sdc /dev/sdd /dev/sde

lvcreate --type raid5 -L 100G -n lvraid10 vg

An administrator wants to add a new swap partition to a Linux system. The partition is /dev/sdb1. Which commands should the administrator run to make the swap space available immediately?

mkswap /dev/sdb1 && swapon /dev/sdb1

mkfs.ext4 /dev/sdb1 && mount /dev/sdb1

swapon /dev/sdb1 && mkswap /dev/sdb1

parted /dev/sdb mklabel gpt && swapon /dev/sdb1

What is the main advantage of thin-provisioned logical volumes compared to standard logical volumes?

They automatically encrypt all data on the volume

They allocate physical space only as data is written, allowing over-provisioning

They provide faster performance than standard volumes in all cases

They are always resized automatically without administrator intervention
