Partition Recovery Course - LDM Recovery Test

Based on what a partition is linked with a component?

disk object ID stored in partition object matches parent volume ID stored in component object
parent component ID stored in partition object matches this object ID stored in component object
parent component ID stored in partition object matches parent volume ID stored in component object

How a partition start is calculated?

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

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

false
true

When recovering LDM manually, you need VBLK blocks to

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

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

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

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

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

Check where PRIVHEAD copies are located on a disk with MBR

anywhere but always before LDM metadata
at the end of the disk
at the beginning of the disk

Disk identification in LDM recovery is done using

GPT or MBR data
LDM database
PRIVHEAD

In what units offsets in PIVHEAD are measured?

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

Check what LDM metadata contains

EFI PART signature
VBLK blocks
PRIVHEAD
partition GUID
