SIMULATION -Resize the logical volume vo and its filesystem to 290 MB. Make sure that the filesystem contents remain intact.Note: Partitions are seldom exactly the same size requested, so a size within the range of 260 MB to 320 MiB is acceptable.
SIMULATION -Create the following users, groups, and group memberships:A group named adminuser.A user natasha who belongs to adminuser as a secondary group A user harry who also belongs to adminuser as a secondary group.A user sarah who does not have access to an interactive shell on the system, and who is not a member of adminuser, natasha, harry, and sarah should all have the password of redhat.
SIMULATION -Configure the permissions of /var/tmp/fstabCopy the file /etc/fstab to /var/tmp/fstab. Configure the permissions of /var/tmp/fstab so that: the file /var/tmp/fstab is owned by the root user. the file /var/tmp/fstab belongs to the group root. the file /var/tmp/fstab should not be executable by anyone. the user natasha is able to read and write /var/tmp/fstab. the user harry can neither write nor read /var/tmp/fstab. all other users (current or future) have the ability to read /var/tmp/fstab.
SIMULATION -Set cronjob for user natasha to do /bin/echo hiya at 14:23.
SIMULATION -Create a collaborative directory/home/admins with the following characteristics:Group ownership of /home/admins is adminuserThe directory should be readable, writable, and accessible to members of adminuser, but not to any other user. (It is understood that root has access to all files and directories on the system.)Files created in /home/admins automatically have group ownership set to the adminuser group
SIMULATION -Install the appropriate kernel update from http://server.domain11.example.com/pub/updates.The following criteria must also be met:The updated kernel is the default kernel when the system is rebootedThe original kernel remains available and bootable on the system
