Partition Recovery Course - LDM Recovery Test

Location of LDM database can be found in PRIVHEAD

true
false

When recovering LDM manually, you need VBLK blocks to

determine Logical Disk Start
determine the location of MBR
determine filesystem type
link various LDM objects

What is in the LDM database?

only VBLK blocks and a transaction log
only VBLK blocks
several blocks of different types and a transaction log

Where is the partition storing LDM metadata located (on a disk with GPT)?

at the beginning of the disk
anywhere
at the end of the disk

Check why PRIVHEAD is that important

it allows to determine RAID configuration
it allows to identify disks
it allows to bind LDM components
it contains the base sector from which all addresses throughout LDM metadata are measured

How a partition start is calculated?

512*(Start LBA) + (Logical Disk Start)
(Start LBA) – (Logical Disk Start)
512*(Start LBA) – (Logical Disk Start)
(Start LBA) + (Logical Disk Start)*(LBAs per physical sector)
(Start LBA) + (Logical Disk Start)

LDM metadata on a disk with GPT is stored in a special partition

false
true

Based on what a partition is linked with a disk?

disk GUID stored in disk object matches parent component ID stored in partition object
disk object ID stored in partition object matches this object ID stored in disk object
disk object ID stored in partition object matches disk GUID stored in PRIVHEAD

Based on what a component is linked with a volume?

parent volume ID stored in component object matches this object ID stored in volume object
component is not linked with volume
this object ID stored in component object matches this object ID stored in volume object

In what units values stored inside VBLK blocks are measured?

in 512-byte sectors
in clusters
in bytes
in physical sectors

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