Perform the following steps:

1. You will first create a normal account and then give it sudo access. Once done, you will be able to use the sudo command from the new account and then execute the administrative commands. Follow the steps given to configure sudo access. First, use the root account to log in to the system then create a user account using the useradd command, as shown. Replace USERNAME in the command with any name of your choice:

2. Now, using the passwd command set a password for the new user account, as shown:
   

3. Now edit the /etc/sudoers file by running the visudo as shown. The policies applied when using the sudo command, are defined by the /etc/sudoers file:
   

4. Once the file is open in the editor, search for the following lines which allow sudo access to the users in the test group:
   

5. You can enable the given configuration by deleting the comment character (#) at the beginning of the second line. Once the changes are done, save the file and exit from the editor. Now using the usermod command, add the previously created user to the test group:
   

6. Now you need to check whether the configuration created now allows the new user account to run commands using sudo.

7. To switch to the newly created user account, use the su option:
   

8. Now use the groups command to confirm the presence of the user account in the test group:
   

Finally, run the whoami command with sudo from the new account. As you have executed a command using sudo for the first time using this new user account, the default banner message will be displayed for the sudo command. The screen will also ask for the user account password to be entered:

9. The last line of the output shown is the username returned by the whoami command. If sudo is configured correctly this value will be root.

You have successfully configured a user with sudo access. You can now log in to this user account and use sudo to run commands the same way as you would from the root user.
