NEW QUESTION # 53
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 be named /dev/sparedisk.
  • B. Symbolic link /dev/sparedisk is created linking to /dev/hdb and with an ide-disk device driver, thus overwriting existing symbolic links.
  • C. 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.
  • D. The matching device will have the kernel device name /dev/hdb.
  • E. 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.

Answer: C,D

Explanation:
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.

NEW QUESTION # 55
Which two statements are true about systemd system and service manager?

  • A. systemd reads /etc/system to determine which services to start.
  • 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. The service command is used to start and stop system service units.
  • D. systemd is backward-compatible with the System V init scripts that were used in earlier versions of Oracle Linux.
  • E. systemd service units expose kernel devices and can be used to implement device-based activation.

Answer: B,D

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 # 56
Which two methods of changing kernel parameters can you use to modify values for the running system?

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

Answer: A,C

Explanation:
Explanation of Answer A:Thesysctl -wcommand is used to modify kernel parameters at runtime. It allows you to set the value of a specific parameter in the/proc/sysdirectory. For example,sysctl -w net.ipv4.
ip_forward=1will enable IP forwarding by writing the value directly to the corresponding file in/proc/sys.
Explanation of Answer B:Using theechocommand to write values directly to specific files in the/proc
/sysdirectory is another method to change kernel parameters dynamically for the running system. For instance, echo 1 > /proc/sys/net/ipv4/ip_forwardachieves the same effect as thesysctl -wcommand.

  • B. chronyd does not poll pool.ntp.org until it is enabled to do so by chronyd.
  • C. chronyd takes pool.ntp.org offline automatically when sending a request to the pool fails.
  • D. chronyd polls a maximum of 3 sources from pool.ntp.org after it is enabled.

Answer: A

Explanation:
Explanation of Answer D:The entrypool pool.ntp.org offlinein the/etc/chrony.conffile specifies that thechronydservice should not automatically poll the NTP pool servers atpool.ntp.orguntil it is explicitly enabled by thechronyccommand. This setting is typically used in environments where the network is not always available (e.g., laptops or isolated systems) to avoid unnecessary polling.
