NAS Recovery Course - NAS Recovery Preparations Test

Choose the advantage of disk clones compared to disk images

reliability
speed
convenience in storage and archival

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

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

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

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

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

true
false

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

EXT i-node
EFI PART signature
GPT database
main MBR

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

false
true

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

yes, but it's better than nothing
no
yes

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 changed an array type
whether a client ever added disks
whether a client ever replaced disks

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

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

We have a mailing list in which we talk about interesting cases we encounter and share some tips and tricks.
