NEW QUESTION # 14
Which two features does a user private group provide?

  • A. Capability to prevent other users from modifying a file
  • B. Provision of a unique group.
  • C. Capability to execute sudo
  • D. Ability for only a group's users to read files in a new directory
  • E. Capability to create new group users

Answer: A,B

Explanation:
* Option A (Correct):A user private group (UPG) ensures that each user has their own unique group created with the same name and ID as the user.
* Option E (Correct):The UPG model helps prevent other users from modifying files by default, as newly created files are assigned to the user's unique group and not to a shared group.
* Option B (Incorrect):UPG does not give the capability to create new group users; this is related to group management commands.
* Option C (Incorrect):UPG does not providesudocapabilities;sudoconfiguration is managed separately.
* Option D (Incorrect):UPGs do not limit reading files to group users by default; it depends on specific file permissions.

Examine this command and output:
# mdadm --detail /dev/md0
/dev/md0:
Version: 1.2
Creation Time: Tue Oct 27 16:53:38 2020
Raid Level: raid5
Array Size: 207872 (203.03 MiB 212.86 MB)
Used Dev Size: 103936 (101.52 MiB 106.43 MB)
Raid Devices: 3
Total Devices: 3
Persistence : Superblock is persistent
Update Time: Tue Oct 27 16:53:38 2020
State: clean, degraded, recovering
Active Devices: 2
Working Devices: 3
Failed Devices: 0
Spare Devices: 1
Layout: left-symmetric
Chunk Size: 512K
Rebuild Status: 60% complete
Name: ol8.example.com:0 (local to host ol8.example.com)
UUID: 70f8bd2f:0505d92d:750a781e:c224508d
Events: 66
Number Major Minor RaidDevice State
0 8 49 0 active sync /dev/sdd1
1 8 65 1 active sync /dev/sde1
3 8 81 2 spare rebuilding /dev/sdf1
Which two are true?

  • A. A RAID device failed and has returned to normal operating status.
  • B. An extra device was added to this RAID set to increase its size.
  • C. A new RAID device was just added to replace a failed one.
  • D. Only write performance is currently sub-optimal on this RAID set.
  • E. The RAID set read and write performance is currently sub-optimal.

Answer: C,E

Explanation:
* Option B (Correct):The output shows that the RAID array is in a "degraded, recovering" state, which means one of the devices failed, and the RAID is currently rebuilding with a spare device. When a RAID-5 array is in a degraded state, its read and write performance is reduced because it cannot utilize all disks in parallel, and data is being rebuilt.
* Option C (Correct):The output indicates that/dev/sdf1is marked as "spare rebuilding." This implies that a new spare device has been added to the RAID array to replace a previously failed device, and it is in the process of rebuilding to restore redundancy.
* Option A (Incorrect):The state of the RAID array is "degraded," which indicates that a RAID device is still being rebuilt. The failed device has not yet returned to normal operating status.
* Option D (Incorrect):No extra device was added to increase the RAID set's size. Instead, a spare device was added to replace a failed one.
* Option E (Incorrect):Both read and write performance are sub-optimal in a degraded RAID-5 state because data is being rebuilt using the remaining active devices.
