Which two are true?
- A. An extra device was added to this RAID set to increase its size.
- B. The RAID set read and write performance is currently sub-optimal.
- C. Only write performance is currently sub-optimal on this RAID set.
- D. A new RAID device was just added to replace a failed one.
- E. A RAID device failed and has returned to normal operating status.
Answer: B,D
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 # 25
Examine these commands, which execute successfully:
# firewall-cmd --zone=public --add-service=cockpit --permanent
# firewall-cmd --zone=public --add-port=1313/tcp --permanent
# firewall-cmd --reload
Which are true upon execution?
- A. Runtime firewall configuration is not lost when the firewalld process is restarted or the system is rebooted.
- B. The custom Cockpit service configuration file is updated in /usr/lib/firewalld/services.
- C. The Cockpit service is added only to the public zone.
- D. Egress traffic is allowed for the Cockpit service only when using port 1313.
- E. Port 1313 blocks all traffic for the public zone except for ingress traffic to the Cockpit service.
Answer: A,C
Explanation:
Explanation of Answer A:The commandfirewall-cmd --zone=public --add-service=cockpit --permanentadds the Cockpit service to the public zone permanently. This means that the service is explicitly allowed only within the public zone, not in any other zones.
Explanation of Answer C:Using the--permanentflag withfirewall-cmdcommands ensures that the changes are stored in the firewalld configuration and are persistent across reboots. Therefore, when thefirewalldservice restarts or the system reboots, the runtime configuration will not be lost, and the changes will remain in effect.

NEW QUESTION # 27
Which three statements are true about the journalctl command?
- A. journalctl -p 6 shows all info log level messages and above.
- B. journalctl -bl -p err fails if journal persistence is not configured.
- C. journalctl -k shows kernel logs since the last boot.
- D. journalctl -p notice..warning shows all messages from notice to warning log level since the last boot.
- E. journalctl -p err shows only error log level.
Answer: A,C,E
Explanation:
Option B: journalctl -p err shows only error log level.
* Explanation:
* The -p or --priority option in journalctl filters messages by their priority level.
* When specifying asingle priority level, journalctl shows messagesonlyat that level.
* The priority levels, as per syslog standards, are:
* 0: emerg
* 1: alert
* 2: crit
* 3: err
* 4: warning
* 5: notice
* 6: info
* 7: debug
* Therefore, journalctl -p err displays messages with priorityerr (3)only.
* Oracle Linux Reference:
* OracleLinux 8: Managing Log Files- Section onFiltering Output withjournalctl:
"Use the -p option to display messages from the journal that have a specific priority level."
* Example:
# journalctl -p err
Option D: journalctl -k shows kernel logs since the last boot.
* Explanation:
* The -k or --dmesg option filters messages from the kernel, equivalent to the output of the dmesg command.
* This option implies -b, which limits the output to messages from the current boot.
* Therefore, journalctl -k displays kernel messages since the last boot.
* Oracle Linux Reference:
* OracleLinux 8: Managing Log Files- Section onViewing Kernel Messages:
"Use the journalctl -k command to display kernel messages since the last system boot."
* Example:
# journalctl -k
Option E: journalctl -p 6 shows all info log level messages and above.
* Explanation:
* When specifying a single numeric priority, journalctl displays messages withthat priority level and higher priority levels(i.e., lower severity).
* Priority levels are ordered from 0 (highest severity) to 7 (lowest severity).
* Therefore, journalctl -p 6 shows messages with priorities:
* 0 (emerg)
* 1 (alert)
* 2 (crit)
* 3 (err)
* 4 (warning)
* 5 (notice)
* 6 (info)
* This includesinfo level messages (6)and all higher priority messages.
* Oracle Linux Reference:
* OracleLinux 8: Managing Log Files- Section onFiltering Output with journalctl:
"When you specify a single priority level, journalctl shows messages at that level and higher severity."
* Example:
# journalctl -p 6
Why Other Options Are Not Correct:
* Option A:journalctl -bl -p err fails if journal persistence is not configured.
* Explanation:
* The -b option displays messages from the current boot. This works even if journal persistence isnotconfigured because the logs from the current boot are stored in volatile memory (/run/log/journal).
* Therefore, the command doesnot failif journal persistence is not configured.
* Oracle Linux Reference:
* OracleLinux 8: Managing Log Files- Section onJournal Volatility:
"By default, the journal stores logs in volatile memory and does not persist logs across reboots unless persistent storage is configured."
* Option C:journalctl -p notice..warning shows all messages from notice to warning log level since the last boot.
* Explanation:
* The -p option allows specifying arangeof priorities. However, the correct order for the range should be from thehigher priority (lower number)to thelower priority (higher number).
* Also, the priorities should be specified in the correct sequence, and ranges are inclusive.
* Moreover, journalctl by default shows messages from all boots unless limited by the -b option.
* Therefore, without -b, it does not limit messages to "since the last boot," making the statement incorrect.
* Correct Command:
* To display messages fromwarning (4)tonotice (5), the command should be:
# journalctl -p warning..notice -b
* But even then, the priorities need to be specified correctly, and the command in Option C is incorrect.
Conclusion:
OptionsB,D, andEare correct because they accurately describe the behavior of the journalctl command in filtering and displaying log messages based on priority levels and sources.
NEW QUESTION # 28
Which two statements are true about systemd system and service manager?
- A. The service command is used to start and stop system service units.
- B. systemd is the first process that starts after the system boots and is the final process left running before the system shuts down.
- C. systemd is backward-compatible with the System V init scripts that were used in earlier versions of Oracle Linux.
- D. systemd reads /etc/system to determine which services to start.
- E. systemd service units expose kernel devices and can be used to implement device-based activation.
Answer: B,C
Explanation:
Explanation of Answer B:systemdis the first process to start (PID 1) after the Linux kernel has booted and is responsible for initializing the user space and managing system services throughout the system's runtime. It is also the last process to stop during shutdown.
Explanation of Answer C:systemdmaintains backward compatibility with older System V init scripts. It can run and manage these scripts, ensuring legacy services are supported while providing newer functionalities through nativesystemdunit files.
NEW QUESTION # 29
Which three are features of the btrfs file system?
- A. Online resizing
- B. Efficient storage for small files
- C. Automatic defragmentation
- D. Block devices mirroring
- E. Copy-on-write metadata
- F. Cluster file system
- G. General-purpose volume manager
Answer: A,C,E
Explanation:
* Option B (Correct):Btrfs uses a copy-on-write mechanism for both data and metadata, which ensures that the file system is more resilient to crashes and data corruption.
* Option E (Correct):Btrfs supports online resizing, meaning that you can change the size of a mounted Btrfs file system without unmounting it.
* Option G (Correct):Btrfs automatically defragments files in the background to maintain performance.
* Option A (Incorrect):While Btrfs does support mirroring, it is not strictly block device mirroring in the traditional sense like RAID; it uses a different approach to redundancy.
* Option C (Incorrect):Btrfs is not a cluster file system; it is designed for local file systems.
* Option D (Incorrect):While Btrfs can store small files efficiently, it is not its primary design goal compared to other file systems optimized specifically for small files.
* Option F (Incorrect):Btrfs is a file system with integrated volume management capabilities but is not a general-purpose volume manager like LVM.
Oracle Linux Reference:Refer to:
* OracleLinux 8: Btrfs File System
* man btrfsfor features and management.
NEW QUESTION # 30

NEW QUESTION # 31
Which two statements are true about removing a physical volume (PV) from a volume group (VG)?
- A. It can be removed when it is part of an active VG.
- B. It can be removed when an active VG has mounted file systems by running vgexport.
- C. It can be removed when an inactive logical volume is on the VG.
- D. It can be removed only after removing it from its VG by using vgreduce.
- E. It cannot be removed when it is part of an active VG.
Answer: C,D
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.
