LPIC-2 Network Client Management Practice Question
Arrange the steps to perform a disaster recovery from a full system backup using tar.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Boot into rescue mode, then prepare disks, then mount the root filesystem, then extract backup using tar, then reboot.
The correct sequence for disaster recovery from a full system backup using tar ensures a logical progression: first gain access to a recovery environment (rescue mode), then prepare the storage devices, mount the target filesystem, restore the data from the backup archive, and finally reboot to the restored system. Any deviation leads to errors such as missing filesystem or incomplete restoration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Boot into rescue mode, then prepare disks, then mount the root filesystem, then extract backup using tar, then reboot.
Why this is correct
This order is correct because you must have a working environment (rescue mode) first, then set up the storage (prepare disks), make it accessible (mount), restore the data (extract backup), and finally restart the system.
- ✗
Boot into rescue mode, then mount the root filesystem, then prepare disks, then extract backup using tar, then reboot.
Why it's wrong here
This is incorrect because you cannot mount a filesystem before the disks are prepared (partitioned and formatted). The mount step requires a ready filesystem.
- ✗
Boot into rescue mode, then prepare disks, then extract backup using tar, then mount the root filesystem, then reboot.
Why it's wrong here
This is incorrect because extracting a backup requires a mounted destination filesystem. You cannot extract data into an unmounted directory.
- ✗
Boot into rescue mode, then prepare disks, then mount the root filesystem, then reboot, then extract backup using tar.
Why it's wrong here
This is incorrect because rebooting before restoring the backup would leave the system without the recovered data. The backup must be extracted before reboot.
