XK0-006 Drag & Drop — 10 Questions

Question 1

Drag and drop the steps to configure SELinux to allow a custom web application to listen on port 8080 in the correct order.

Accepted Answer

List current SELinux port mappings, then add port 8080 to http_port_t, then verify the new mapping, then restart the web service. SELinux requires adding the port to the appropriate context before the service can listen.

Answer

Add port 8080 to http_port_t, then list current mappings, then verify, then restart

Answer

List current mappings, then verify, then add port, then restart

Answer

Add port 8080 to http_port_t, then verify, then list, then restart

Question 2

Accepted Answer

Edit the network configuration file, configure the static IP address, save the file, restart the network service.. Static IP configuration involves editing the network config file and restarting the service to apply changes.

Answer

Restart the network service, edit the network configuration file, configure the static IP address, save the file.

Answer

Edit the network configuration file, save the file, configure the static IP address, restart the network service.

Answer

Configure the static IP address, restart the network service, edit the network configuration file, save the file.

Question 3

Drag and drop the steps to create a new LVM logical volume in the correct order.

Accepted Answer

Create physical volumes, then create volume group, then create logical volume, then format the logical volume, then mount the logical volume.. LVM requires physical volumes, a volume group, and then a logical volume before formatting and mounting.

Answer

Create volume group, then create physical volumes, then create logical volume, then format the logical volume, then mount the logical volume.

Answer

Create physical volumes, then create volume group, then format the logical volume, then create logical volume, then mount the logical volume.

Answer

Create physical volumes, then create logical volume, then create volume group, then format the logical volume, then mount the logical volume.

Question 4

Drag and drop the steps to configure a firewall rule using iptables to allow SSH in the correct order.

Accepted Answer

Add SSH allow rule, then set INPUT default DROP, then save rules. Firewall configuration typically involves adding allow rules before setting default drop and saving.

Answer

Set INPUT default DROP, then add SSH allow rule, then save rules

Answer

Add SSH allow rule, then save rules, then set INPUT default DROP

Answer

Save rules, then add SSH allow rule, then set INPUT default DROP

Question 5

Drag and drop the steps to troubleshoot a network connectivity issue using common commands in the correct order.

Accepted Answer

Verify IP configuration (ip addr), check default gateway (ip route), test DNS resolution (nslookup), ping remote host (ping). Troubleshooting network connectivity should follow a logical progression from local to remote: first verify your own IP address and subnet mask, then check the default gateway, then test DNS resolution, and finally test connectivity to a remote host. This systematic approach helps isolate the root cause efficiently.

Answer

Verify IP configuration (ip addr), test DNS resolution (nslookup), check default gateway (ip route), ping remote host (ping)

Answer

Ping remote host (ping), verify IP configuration (ip addr), check default gateway (ip route), test DNS resolution (nslookup)

Answer

Check default gateway (ip route), verify IP configuration (ip addr), test DNS resolution (nslookup), ping remote host (ping)

Question 6

Drag and drop the steps to set up a cron job that runs a script daily in the correct order.

Accepted Answer

Write the script, then make it executable, then add a crontab entry with daily schedule, then verify with crontab -l. Setting up a cron job correctly involves first writing the script that will be executed, then making it executable with chmod +x, then adding a crontab entry using crontab -e with the correct time specification (e.g., '0 0 * * *' for daily at midnight), and finally verifying the job is listed with crontab -l. This order ensures the script is ready and permissions are set before cron attempts to run it, and verification confirms the entry is valid.

Answer

Write the script, then add a crontab entry with daily schedule, then make it executable, then verify with crontab -l

Answer

Make the script executable, then write the script, then add a crontab entry, then verify with crontab -l

Answer

Add a crontab entry with daily schedule, then write the script, then make it executable, then verify with crontab -l

Question 7

Drag and drop the steps to create and apply a systemd service unit in the correct order.

Accepted Answer

1. Create the service unit file in /etc/systemd/system/. 2. Run systemctl daemon-reload. 3. Run systemctl enable myservice.service. 4. Run systemctl start myservice.service.. The correct sequence to create and apply a systemd service unit is: create the unit file in /etc/systemd/system/, then run systemctl daemon-reload to load the new unit, then run systemctl enable to set it to start on boot, and finally run systemctl start to start it immediately. Common mistakes include enabling before reloading, starting before enabling, or attempting to enable a non-existent unit.

Answer

1. Create the service unit file. 2. Run systemctl enable myservice.service. 3. Run systemctl daemon-reload. 4. Run systemctl start myservice.service.

Answer

1. Create the service unit file. 2. Run systemctl daemon-reload. 3. Run systemctl start myservice.service. 4. Run systemctl enable myservice.service.

Answer

1. Run systemctl enable myservice.service. 2. Create the service unit file. 3. Run systemctl daemon-reload. 4. Run systemctl start myservice.service.

Question 8

Drag and drop the steps to add a new user to the system in the correct order.

Accepted Answer

Step 1: Create user account, Step 2: Set user password, Step 3: Configure home directory. Adding a user typically involves creating the user, setting a password, and configuring the home directory.

Answer

Step 1: Set user password, Step 2: Create user account, Step 3: Configure home directory

Answer

Step 1: Configure home directory, Step 2: Create user account, Step 3: Set user password

Answer

Step 1: Create user account, Step 2: Configure home directory, Step 3: Set user password

Question 9

Drag and drop the steps to mount a new filesystem in the correct order.

Accepted Answer

Create mount point directory, then mount device, then update /etc/fstab, then verify mount. Mounting a filesystem requires creating a mount point and using the mount command with the device and mount point.
