NAS Recovery Course - NAS Recovery Preparations Test

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

true
false

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

false
true

Choose the advantage of disk images compared to disk clones

speed
convenience in storage and archival
reliability

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

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

Choose the advantage of disk clones compared to disk images

speed
convenience in storage and archival
reliability

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

EFI PART signature
main MBR
EXT i-node
GPT database

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

yes, but it's better than nothing
no
yes

You need to check sector sizes for each disk form a NAS when

a client does not remember what sector sizes he/she set up when installing disks
disks of different models are used in a NAS
array type has been changed

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

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

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