Question 5

Order the steps to add a new user to the system and grant sudo privileges.

Accepted Answer

Create the user account using useradd, set the password using passwd, then add the user to the sudo group using usermod -aG sudo. User creation uses useradd, then password is set, and adding to sudo group grants privileges.

Answer

Create the user account using useradd, add the user to the sudo group using usermod -aG sudo, then set the password using passwd

Answer

Set the password using passwd, create the user account using useradd, then add the user to the sudo group using usermod -aG sudo

Question 6

Order the steps to create and apply a file system permission using ACLs.

Accepted Answer

Mount the filesystem with the acl option, then use setfacl to apply ACL rules, then use getfacl to verify ACL rules.. ACLs require the filesystem to be mounted with the acl option, then setfacl applies rules, and getfacl verifies them.

Answer

Use setfacl to apply ACL rules, then mount the filesystem with the acl option, then use getfacl to verify ACL rules.

Answer

Use getfacl to verify ACL rules, then use setfacl to apply ACL rules, then mount the filesystem with the acl option.

Answer

Mount the filesystem with the acl option, then use getfacl to verify ACL rules, then use setfacl to apply ACL rules.

Question 10

Arrange the steps to create a LVM logical volume and mount it.

Accepted Answer

Step 1: Create physical volumes, Step 2: Create volume group, Step 3: Create logical volume, Step 4: Format and mount.
