NAS Recovery Course - NAS Recovery Preparations Test

Check what you should ask a client about a NAS configuration

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

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

Choose the advantage of disk clones compared to disk images

reliability
convenience in storage and archival
speed

What do you need to try if the sum of sizes of partitions does not correspond to the size of a physical disk and you suspect the sector size is uncorrect?

divide the total size of partitions by 8
multiply the total size of partitions by 4
multiply the total size of partitions by 8

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

no
yes, but it's better than nothing
yes

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

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

false
true

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

false
true

Choose the advantage of disk images compared to disk clones

convenience in storage and archival
