NAS Recovery Course - NAS Recovery Preparations Test

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

Choose the advantage of disk clones compared to disk images

reliability
convenience in storage and archival
speed

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

false
true

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

EXT i-node
GPT database
main MBR
EFI PART signature

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

true
false

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?

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

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

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

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

yes, but it's better than nothing
no
yes

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