Which two statements are true according to Enterprise Installation Stan (EIS) regarding boot disk layout? 

For ZFS-based root file systems, EIS recommends you do not use H/W RAID 1 unless sufficient disks are available for ZFS to mirror itself. 

For ZFS-based root file systems, EIS recommends you do not use H/W RAID 0 unless sufficientdisks are available for ZFS to mirror itself. 

Under ZFS, the boot devices/disks are placed in a ZFS poof (called rpool by default), and all datasets (consisting of file systems and volumes) are allocated flexibly from that pool. 

For UFS-based root file systems, EIS recommends that H/W RAID 0 be used to mirror the
bootdisk wherever it is available.
