XK0-006 PDF 71 Questions

HOTSPOT (Drag and Drop is not supported)

A new drive was recently added to a Linux system. Using the environment and tokens provided, complete the following tasks:

Create an appropriate device label.
Format and create an ext4 file system on the new partition.

The current working directory is /.

INSTRUCTIONS

Use the drop-down menus to select the proper objects to complete these tasks.

Some commands are partially complete.

Not all objects will be used, and some may be used more than once.

If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




mklabel gpt initializes the new disk /dev/sdc with a GPT partition table.

mkpart primary ext4 1 10G creates a primary partition using the ext4 type between 1MB and 10GB on /dev/sdc.

mkfs.ext4 /dev/sdc1 formats the newly created partition /dev/sdc1 with the ext4 filesystem, completing the setup.



SIMULATION

A junior system administrator removed an LVM volume by mistake.

INSTRUCTIONS

Part 1

Review the output and select the appropriate command to begin the recovery process.

Part2

Review the output and select the appropriate command to continue the recovery process.

Part 3

Review the output and select the appropriate command to complete the recovery process and access the underlying data.

If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.





  1. See Explanation section for answer.

Answer(s): A

Explanation:



Restoring the Volume Group (VG) configuration from the LVM archive begins the recovery process after the VG metadata was lost.



After restoring the VG metadata, the logical volume must be reactivated (-ay) so it becomes accessible to the system.



Once the LV is active, mounting it to the /important_data directory makes the filesystem accessible, completing the recovery process.



SIMULATION

You are a systems administrator and have created an uncompressed backup of the application directory. Several hours later, you must restore the application from backup.

INSTRUCTIONS

Within each tab, click on an object to form the appropriate command used to create the backup and restore the application.

Command objects may only be used once, but the spacebar object may be used multiple times. Not all objects will be used. Click the arrow to remove any unwanted objects from your command.

If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.



  1. See Explanation section for answer.

Answer(s): A

Explanation:





-cvf creates (-c) a verbose (-v) archive file (-f) named /backups/application.tar.

-C /opt/ application changes to /opt/ so only the relative application directory is saved, avoiding absolute paths.

-xvf extracts (-x) the same archive, and -C /opt/ restores the contents back into the original location.



Which of the following Ansible components contains a list of hosts and host groups?

  1. Fact
  2. Inventory
  3. Playbook
  4. Collection

Answer(s): B

Explanation:

In Ansible, the inventory defines the list of managed nodes (hosts) and groups of hosts. It is the source from which Ansible knows what systems to configure or manage.



Which of the following filesystems contains non-persistent or volatile data?

  1. /boot
  2. /usr
  3. /proc
  4. /var

Answer(s): C

Explanation:

The /proc filesystem is a virtual filesystem that provides process and kernel information. It is non-persistent and volatile, meaning its contents exist only in memory and are regenerated at each system boot.



An administrator needs to verify the user ID, home directory, and assigned shell for the user named "accounting." Which of the following commands should the administrator use to retrieve this information?

  1. qetent passwd accounting
  2. id accounting
  3. grep accounting /etc/shadow
  4. who accounting

Answer(s): A

Explanation:

The getent passwd accounting command retrieves the user's entry from the system's password database, showing fields such as username, UID, GID, home directory, and assigned shell.



A Linux user needs to download the latest Debian image from a Docker repository.
Which of the following commands makes this task possible?

  1. docker image init debian
  2. docker image pull Debian
  3. docker image import debian
  4. docker image save debian

Answer(s): B

Explanation:

The docker image pull command downloads an image from a Docker repository (such as Docker Hub). Using docker image pull debian retrieves the latest Debian image.



In the echo "profile-$num-$name" line of a shell script, the variable $num seems to not be expanding during execution.
Which of the following notations ensures the value is expanded?

  1. echo "profile-$(num)-$name"
  2. echo 'profile-$num-$name'
  3. echo "profile-`Snum`-$name"
  4. echo "profile-${num}-$name"

Answer(s): D

Explanation:

Using ${num} ensures correct variable expansion, especially when variables are adjacent to other characters or hyphens. This prevents ambiguity and guarantees $num is properly expanded within the string.

answer to this question "what administrative safeguards should be implemented to protect the collected data while in use by manasa and her product management team? " it should be (c) for the following reasons: this administrative safeguard involves controlling access to collected data by ensuring that only individuals who need the data for their job responsibilities have access to it. this helps minimize the risk of unauthorized access and potential misuse of sensitive information. while other options such as (a) documenting data flows and (b) conducting a privacy impact assessment (pia) are important steps in data protection, implementing a "need to know" access policy directly addresses the issue of protecting data while in use by limiting access to those who require it for legitimate purposes. (d) is not directly related to safeguarding data during use; it focuses on data transfers and location.

password lockout being the correct answer for question 37 does not make sense. it should be geofencing.
