Oracle 1z0-106 Exam With Confidence Using Practice Dumps

Option A (Correct):The/procfile system is a pseudo-file system that contains runtime system information (e.g., system memory, mounted devices, hardware configuration, etc.). Files such as/proc/meminfoand/proc/cpuinfoprovide detailed information about memory and CPUs, respectively.

Option C (Correct):The/sysfile system, also known as sysfs, provides a view of the kernel's device model. It contains information about system hardware, including CPUs and memory. For example,/sys/devices/system/cpu/contains directories and files that provide detailed information about each CPU.

Option B (Incorrect):The/sysfile system does not contain a list of running processes. Running processes are listed in the/procfile system, with each process having its own directory under/proc.

Option D (Incorrect):/procdoes not contain a list of network drivers specifically. Network driver information is available under/proc/net, but this does not equate to a list of drivers.

Option E (Incorrect):The/sysfile system does not contain a list of mounted devices. Mounted devices are listed in/proc/mountsor the/etc/mtabfile.

Option C (Correct):The-k passpart of theauditctlcommand defines a keyword (pass) for the audit rule. This keyword helps in filtering and searching logs in the audit trail.

Option D (Correct):The-w /etc/passwd -p wpart of the command sets up a watch on the/etc/passwdfile for write (w) operations. This audit rule will generate a log entry every time there is a write operation to/etc/passwd.

Option A (Incorrect):This command does not write directly to/etc/audit/rules.d/audit.rules; it defines a rule in memory that could be saved to this file later.

Option B (Incorrect):The rule only logs write (w) operations; it does not log read operations.

Option E (Incorrect):The command does not directly cause a write to/etc/audit/audit.rules.

man auditctlfor details on audit rules and options.

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.
