NAS Recovery Course - NAS Recovery Preparations Test

Check based on what you can estimate the state of physical disks in a NAS

sounds coming from the disks
the words of a client
the S.M.A.R.T. attributes

What helps you determine a sector size for disks partitioned with GPT?

EXT i-node
GPT database
EFI PART signature
main MBR

Choose the advantage of disk clones compared to disk images

reliability
convenience in storage and archival
speed

Check what you should ask a client about a NAS configuration

whether a client used disks of the same model in a NAS
whether a client ever replaced disks
whether a client changed an array type
whether a client ever added disks

The sum of partition sizes should be close to the size of a physical disk with both MBR and GPT disks

false
true

Check those S.M.A.R.T. attributes pointing to the bad condition of a disk

Choose the advantage of disk images compared to disk clones

speed
convenience in storage and archival
reliability

Why they do not recommend storing several disk image files on the same disk when recovering data?

the disk may degrade due to the frequent read requests
recovery will be too slow

The information about a NAS coming from a client is often unreliable

no
yes, but it's better than nothing
yes

When recovering a NAS, it is always better to create disk image files rather than disk clones

false
true
