NEW QUESTION # 463
A Linux engineer needs to create a custom script, cleanup.sh, to run at boot as part of the system services.
Which of the following processes would accomplish this task?

  • A. Create a unit file in the /etc/ske1/ directory.systemct1 enable cleanupsystemct1 is-enabled cleanup
  • B. Create a unit file in the /etc/sysctl.d/ directory.systemct1 enable cleanupsystemct1 is-enabled cleanup
  • C. Create a unit file in the /etc/default/ directory.systemct1 enable cleanupsystemct1 is-enabled cleanup
  • D. Create a unit file in the /etc/systemd/system/ directory.systemct1 enable cleanupsystemct1 is-enabled cleanup

Answer: D

Explanation:
The process that will accomplish the task of creating a custom script to run at boot as part of the system services is:
Create a unit file in the /etc/systemd/system/ directory. A unit file is a configuration file that defines the properties and behavior of a systemd service. The systemd is a system and service manager that controls the startup and operation of Linux systems. The /etc/systemd/system/ directory is the location where the administrator can create and store custom unit files. The unit file should have a name that matches the name of the script, such as cleanup.service, and should contain the following sections and options:
[Unit]: This section provides the general information about the service, such as the description, dependencies, and conditions. The administrator should specify the following options in this section:
Description: A brief description of the service, such as "Custom cleanup script".
After: The name of another unit that this service should start after, such as "network.target".
ConditionPathExists: The path of the file or directory that must exist for the service to start, such as "/opt
/scripts/cleanup.sh".
[Service]: This section defines how the service should be started and stopped, and what commands should be executed. The administrator should specify the following options in this section:
Type: The type of the service, such as "oneshot", which means that the service will run once and then exit.
ExecStart: The command that will start the service, such as "/bin/bash /opt/scripts/cleanup.sh".
RemainAfterExit: A boolean value that indicates whether the service should remain active after the command exits, such as "yes".
[Install]: This section defines how the service should be enabled and under what circumstances it should be started. The administrator should specify the following option in this section:
WantedBy: The name of another unit that wants this service to be started, such as "multi-user.target", which means that the service will be started when the system reaches the multi-user mode.
Run the command systemct1 enable cleanup. This command will enable the service and create the necessary symbolic links to start the service at boot.
Run the command systemct1 is-enabled cleanup. This command will check the status of the service and confirm that it is enabled.
This process will create a custom script, cleanup.sh, to run at boot as part of the system services. This is the correct process to use to accomplish the task. The other options are incorrect because they either use the wrong directory for the unit file (/etc/default/, /etc/skel/, or /etc/sysctl.d/) or do not create a unit file at all.

NEW QUESTION # 464
The administrator comptia is not able to perform privileged functions on a newly deployed system. Given the following command outputs:

Which of the following is the reason that the administrator is unable to perform the assigned duties?

  • A. The administrator is not a part of the correct group.
  • B. The administrator did not update the sudo database.
  • C. The administrator needs a password reset.
  • D. The administrator's credentials need to be more complex.

Answer: A

Explanation:
Explanation
The reason that the administrator is unable to perform the assigned duties is because the administrator is not a part of the correct group. This is option B.
Based on the image that you sent, I can see that the user comptia has a user ID and a group ID of 1000, and belongs to only one group, which is also comptia. However, the sudoers file, which defines the permissions for users to run commands as root or other users, does not include the comptia group in any of the entries.
Therefore, the user comptia cannot use sudo to perform privileged functions on the system.
The other options are incorrect because:
A: The administrator needs a password reset.
This is not true, because the password aging information for the user comptia shows that the password was last changed on Oct 24, 2023, and it does not expire until Jan 22, 2024. There is no indication that the password is locked or expired.
C: The administrator did not update the sudo database.
This is not necessary, because the sudo database is automatically updated whenever the sudoers file is modified. There is no separate command to update the sudo database.
D: The administrator's credentials need to be more complex.
This is not relevant, because the complexity of the credentials does not affect the ability to use sudo. The sudoers file does not specify any password policy for the users or groups that are allowed to use sudo.


NEW QUESTION # 465
A Linux engineer is removing a previously created firewall rule. Which of the following commands will help the administrator accomplish this task?

  • A. ufw delete 80/tcp
  • B. ufw delete 80/tcp deny
  • C. delete7!
  • D. ufw delete deny 80/tcp

Answer: D

Explanation:
The ufw (Uncomplicated Firewall) delete command is used to remove rules. If the original rule was ufw deny 80/tcp, it must be deleted with: ufw delete deny 80/tcp


NEW QUESTION # 466
What is the main objective when using Application Control?

  • A. To filter out specific content.
  • B. To see what users are doing.
  • C. Ensure security and privacy of information.
  • D. To assist the firewall blade with handling traffic.

Answer: C

Explanation:
The main objective when using Application Control is to ensure the security and privacy of information.
Application Control is a security practice that blocks or restricts unauthorized applications from executing in ways that put data at risk. The control functions vary based on the business purpose of the specific application, but the main objective is to help ensure the privacy and security of data used by and transmitted between applications1. Application Control can also prevent malware, untrusted, or unwanted applications from running on the network, reducing the risks and costs associated with data breaches1. Application Control can also improve the overall network stability and performance by eliminating unnecessary or harmful applications1.
Application Control is not mainly used to filter out specific content, although it can be combined with other technologies such as URL filtering or content filtering to achieve that goal. Application Control is not mainly used to assist the firewall blade with handling traffic, although it can be integrated with firewall policies to enforce granular access rules based on applications. Application Control is not mainly used to see what users are doing, although it can provide visibility and reporting on application usage and activity.


NEW QUESTION # 467
Users have been unable to reach www.comptia.org from a Linux server. A systems administrator is troubleshooting the issue and does the following:

Based on the information above, which of the following is causing the issue?

  • A. The name www.comptia.org does not point to a valid IP address.
  • B. The server 192.168.168.53 is unreachable.
  • C. The network interface eth0 is disconnected.
  • D. No default route is set on the server.

Answer: B

Explanation:
The issue is caused by the server 192.168.168.53 being unreachable. This server is the DNS server configured in the /etc/resolv.conf file, which is used to resolve domain names to IP addresses. The ping command shows that the server cannot be reached, and the nslookup command shows that the name www.comptia.org cannot be resolved using this server. The other options are incorrect because:
The name www.comptia.org does point to a valid IP address, as shown by the nslookup command using another DNS server (8.8.8.8).
The default route is set on the server, as shown by the ip route command, which shows a default gateway of 192.168.168.1.
The network interface eth0 is connected, as shown by the ip link command, which shows a state of UP for eth0.
