NAS Recovery Course - NAS Recovery Preparations Test

Check what information you can get if you know a NAS vendor and exact NAS model

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

EFI PART signature
GPT database
EXT i-node
main MBR

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

false
true

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

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

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

yes, but it's better than nothing
no
yes

Choose the advantage of disk clones compared to disk images

convenience in storage and archival
speed
reliability

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

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

Choose the advantage of disk images compared to disk clones

reliability
speed
convenience in storage and archival

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

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