Oracle Linux 8 Advanced System Administration Sample Questions (Q37-Q42):

NEW QUESTION # 37
Which two statements are true about removing a physical volume (PV) from a volume group (VG)?

A. It can be removed when an inactive logical volume is on the VG.
B. It cannot be removed when it is part of an active VG.
C. It can be removed only after removing it from its VG by using vgreduce.
D. It can be removed when an active VG has mounted file systems by running vgexport.
E. It can be removed when it is part of an active VG.

Answer: A,C

Explanation:
To remove a physical volume (PV) from a volume group (VG), it must first be removed using thevgreducecommand. This operation ensures that the VG no longer contains any references to the PV being removed.
Explanation of Answer D:A physical volume can be removed if there are no active logical volumes (LVs) on the VG that require space from that PV. If the LV is inactive, the PV can be safely removed from the VG.

NEW QUESTION # 38
Which two methods of changing kernel parameters can you use to modify values for the running system?

A. Using the echo command to write values to specific files in the /sys directory.
B. Issuing the sysctl -w command to write values to specific files in the /proc/sys directory.
C. Using the echo command to write values to specific files in the /proc/sys directory.
D. Issuing the sysctl -w command to write values to specific files in the /sys directory.
E. Adding to or modifying parameters and values in the /etc/sysctl.conf file followed by issuing the sysctl -p command.

Answer: B,C

NEW QUESTION # 39
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. Only write performance is currently sub-optimal on this RAID set.
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. A RAID device failed and has returned to normal operating status.
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.

NEW QUESTION # 40
Examine this udev device naming rule which gets processed successfully:
makefile
KERNEL=="hdb", DRIVER=="ide-disk", SYMLINK+="sparedisk"
Which two statements are true?

A. The matching device will have the kernel device name /dev/hdb.
B. Symbolic link /dev/sparedisk is created for a device named /dev/hdb which has an ide-disk device driver if such a device is discovered.
C. Symbolic link /dev/sparedisk is created for a device named /dev/hdb or one that has an ide-disk device driver, whichever is discovered first.
D. The matching device will be named /dev/sparedisk.
E. Symbolic link /dev/sparedisk is created linking to /dev/hdb and with an ide-disk device driver, thus overwriting existing symbolic links.

Answer: A,B

NEW QUESTION # 41
Examine this command:
$ podman run -name=oracleshell -it oraclelinux:8 -slim
Which two statements are true upon execution?

A. The container creates and starts an interactive shell.
B. The container is created and started in a single command.
C. The container is removed by typing exit at the bash shell prompt.
D. The container named oracleshell must already exist; otherwise, the command fails.
E. The command fails if the oraclelinux:8 -slim image does not exist on the local machine.

Answer: A,B

Explanation:
Understanding the Command:
$ podman run --name=oracleshell -it oraclelinux:8-slim
(Note: The image is likely oraclelinux:8-slim without a space.)
* podman run:Creates and starts a new container.
* --name=oracleshell:Assigns the name oracleshell to the container.
* -it:Runs the container in interactive mode with a pseudo-TTY.
* oraclelinux:8-slim:Specifies the image to use.
Option A: The container creates and starts an interactive shell.
* Explanation:
* The -it option runs the container interactively.
* If no command is specified, it executes the default command in the image (usually /bin/bash).
* This provides an interactive shell inside the container.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Running Containers Interactively:
"You can run a container in interactive mode using the -i and -t options together." Option D: The container is created and started in a single command.
* Explanation:
* The podman run command handles both creation and starting of the container.
* There's no need to create the container separately.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Creating and Running Containers:
"The podman run command creates and starts a container in one operation." Why Other Options Are Incorrect:
Option B:The container does not need to pre-exist; podman run creates it if it doesn't exist.
Option C:If the image doesn't exist locally, podman will attempt to pull it from the registry.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Pulling Images:
"If you attempt to run a container with an image that does not exist locally, Podman automatically pulls the image from a registry." Option E:The container is not removed upon exit unless the --rm option is used.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Automatically Removing Containers:
"Use the --rm option to automatically remove the container when it exits." Conclusion:
* Correct Options:A, D
* Summary:The command creates and starts a new container named oracleshell and opens an interactive shell session inside it.
