Partition Recovery Course - LDM Recovery Test

Location of LDM database can be found in PRIVHEAD

false
true

What is in the LDM database?

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

Where is LDM database located on a disk with MBR?

at the beginning of the disk
anywhere but after PRIVHEAD
at the end of the disk

Check what you need to get from VBLK blocks describing a disk when recovering LDM

this object ID
disk GUID
parent component ID
Logical Disk Start

Check what you need to get from VBLK blocks describing a component when recovering LDM

partition start LBA
disk object ID
parent volume ID
this object ID

What you need to get from VBLK blocks describing a volume when recovering LDM?

disk object ID
this object ID
partition start LBA
parent volume ID

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

All sector addresses throughout LDM metadata are measured from the beginning of the disk

false
true

Check what LDM metadata contains

VBLK blocks
partition GUID
PRIVHEAD
EFI PART signature

How a partition start is calculated?

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