You need to identify which process is listening on TCP port 8080 and then stop it in a way that allows it to clean up resources (graceful stop). Which approach best meets the requirement?

A log file `/var/log/app.log` contains lines like `2026-01-23 user=alice action=login status=fail`. You must display a list of unique usernames that had at least one `status=fail`, sorted alphabetically. Which command pipeline is most appropriate?

A new admin ran `chmod 640 /shared` on a directory that should allow members of group `dev` to create and delete files inside it. After the change, users can list the directory but cannot create files. What is the best fix to meet the requirement while keeping others out?

You need a shell script that checks whether `/data` is mounted. If it is not mounted, the script should mount it and then log a message to syslog with tag `data-mount`. Which snippet best satisfies the requirement?

A systemd service named `webapp.service` fails to start after a configuration change. You must quickly view the error messages from the most recent start attempt and then prevent the service from starting automatically at boot until the issue is fixed. Which set of commands best meets both goals?

You need to schedule a one-time maintenance script `/root/cleanup.sh` to run at 02:30 tomorrow, even if you log out. Which method is most appropriate on an RHCSA-managed system?

A new 20G disk `/dev/sdb` has been attached. You must create an LVM setup where the filesystem can later be expanded by adding more disks. The requirement is: one volume group `vgdata` and one logical volume `lvdata` using all space on `/dev/sdb`. Which sequence is correct?

You created an XFS filesystem on `/dev/vgdata/lvdata` and mounted it at `/data`. Later, management asks you to expand the filesystem by 5G after extending the logical volume accordingly. Which command should you use to grow the filesystem online?

You need a persistent mount of `/dev/vgdata/lvdata` at `/data` with these requirements: mount should occur automatically at boot, and it should not block the boot process if the device is missing (the system must still boot). What is the best `/etc/fstab` approach?

A system must allow SSH access for users in group `wheel` only, while still permitting root to log in using keys (not passwords). Which configuration change best meets the requirement?
