Option C (Correct):If a device named/dev/hdbwith theide-diskdriver is discovered, a symbolic link/dev/sparediskwill be created, pointing to/dev/hdb.

Option D (Correct):TheKERNEL=="hdb"match specifies that the device will have the kernel device name/dev/hdb.

Option A (Incorrect):This is incorrect because existing symbolic links are not overwritten unless explicitly defined.

Option B (Incorrect):The device itself is not renamed to/dev/sparedisk; rather, a symbolic link is created.

Option E (Incorrect):The rule specifically requires bothKERNEL=="hdb"andDRIVER=="ide-disk"to match; it is not an either/or condition.

Explanation of Answer B:iostatis a tool used to monitor system input/output device loading by observing the time devices are active concerning their average transfer rates. The "Device Utilization Report" provides statistics about device utilization and throughput rates, which is critical in identifying performance bottlenecks.

Explanation of Answer E:iostatalso generates "CPU Utilization Reports." These reports provide data about how the CPU is utilized during input/output operations, showing the percentage of CPU time used for user processes, system processes, and the time the CPU remains idle.

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.
