XK0-006 Dumps With Exact Questions and Answers

Network configuration changes can cause immediate loss of connectivity if applied incorrectly. Linux+ V8 emphasizes safe configuration practices, particularly when managing remote systems.

The netplan try command applies network configuration changes temporarily and prompts the administrator to confirm them within a timeout period. If the administrator does not confirm, Netplan automatically rolls back to the previous working configuration. This prevents accidental outages caused by misconfigured network settings.

The netplan apply command makes changes permanent immediately and does not provide rollback protection. The other options are not valid Netplan commands.

Linux+ V8 documentation explicitly references netplan try as a safe testing mechanism. Therefore, the correct answer is A.

Service management using systemd is a core Linux+ V8 system management objective. Administrators frequently need to view the current status of all services to determine which ones are running, stopped, failed, or inactive.

The correct command is systemctl list-units --type=services, which displays all loaded service units along with their current state, including whether they are active, inactive, failed, or running. This provides a comprehensive, real-time view of service statuses on the system and is commonly used during troubleshooting and audits.

Option A, systemctl is-active, is designed to check the status of a single service, not all services. Option B lists socket units, not services. Option C, systemctl is-enabled, checks whether services are enabled at boot, not whether they are currently running.

Linux+ V8 documentation explicitly references systemctl list-units --type=service as the primary command for viewing service runtime states. Therefore, the correct answer is D.

To create an appropriate device label, format and create an ext4 file system on the new partition, you can use the following commands:

To create a GPT (GUID Partition Table) label on the new drive /dev/sdc, you can use the parted command with the -s option (for script mode), the device name (/dev/sdc), the mklabel command, and the label type (gpt). The command is:

parted -s /dev/sdc mklabel gpt

To create a primary partition of 10 GB on the new drive /dev/sdc, you can use the parted command with the -s option, the device name (/dev/sdc), the mkpart command, the partition type (primary), the file system type (ext4), and the start and end points of the partition (1 and 10G). The command is:

parted -s /dev/sdc mkpart primary ext4 1 10G

To format and create an ext4 file system on the new partition /dev/sdc1, you can use the mkfs command with the file system type (ext4) and the device name (/dev/sdc1). The command is:

mkfs.ext4 /dev/sdc1

You can verify that the new partition and file system have been created by using the lsblk command, which will list all block devices and their properties.
