Option B (Correct):The-Ior--interpretoption inausearchconverts the numerical system call numbers into their corresponding text names, making the output easier to understand.

Option C (Correct):The-scoption specifies the system call by name (mkdir), which helps in finding audit logs related to that particular system call in text format.

Option A, D, E (Incorrect):These options do not specifically translate the numeric system call numbers into human-readable text. OptionAfilters by the numeric ID,Dis an invalid option, andEreverses the search order but does not affect the format.

The Linux Auditing System can be configured to log various activities, including administrator attempts to access user home directories. Audit rules can be defined to monitor access to specific files or directories, and any access attempts will be logged in the audit logs.

Explanation of Answer B:Auditing system calls can generate a large amount of log data, which may affect system performance. The more detailed the audit rules, the greater the potential performance impact, as every event that matches a rule must be recorded.

Option A (Correct):In rsyslog, afilteris used to determine which messages should be selected for further processing. Filters can be based on different criteria such as facility, severity, or specific message content.

Option B (Correct):Anactionin rsyslog defines what to do with messages that match a filter. Actions can include writing to a log file, sending to a remote server, running a script, etc.

Option C (Incorrect):A parser is not typically a component for creating a new rsyslog rule; it is involved in interpreting message formats.

Option D (Incorrect):A module in rsyslog is a loadable component that provides additional capabilities, such as support for different protocols or output formats. It is not a direct component of a logging rule.

Option E (Incorrect):Security policy is unrelated to the basic components used for defining rsyslog rules.

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.

The/etc/sysconfigdirectory contains configuration files for various system services and applications. The content of this directory depends on which packages are installed on the system. Each package may provide one or more configuration files stored in/etc/sysconfigto control its behavior.
