  1. An administrator wants to add the output of df -h to the end of /root/report.txt without overwriting what is already in the file. Which operator should be used?

    • A. df -h > /root/report.txt
    • B. df -h >> /root/report.txt ✔ correct
    • C. df -h < /root/report.txt
    • D. df -h | /root/report.txt

    Answer: B. >> appends standard output to the end of the file. A single > truncates the file first, < redirects input, and a pipe sends output to another command, not to a file.

  2. On RHEL 10, where do you place a .repo file so that DNF can use a custom software repository?

    • A. /var/lib/rpm/
    • B. /etc/sysconfig/network-scripts/
    • C. /etc/yum.repos.d/ ✔ correct
    • D. /usr/share/doc/dnf/

    Answer: C. DNF reads repository definitions from .repo files in /etc/yum.repos.d/ (or from /etc/dnf/dnf.conf). dnf config-manager --add-repo creates such a file for you; /var/lib/rpm holds the RPM database.

  3. In a Bash script, $1 holds the first argument passed to the script on the command line.

    • A. True ✔ correct
    • B. False

    Answer: A. True. Positional parameters $1, $2 and so on hold the script's arguments in order, $# holds how many there are, and $0 is the script name itself.

  4. Which setting makes systemd-journald store the journal on disk so that logs survive a reboot?

    • A. Storage=volatile in /etc/systemd/journald.conf
    • B. Storage=none in /etc/systemd/journald.conf
    • C. ForwardToConsole=yes in /etc/systemd/journald.conf
    • D. Storage=persistent in /etc/systemd/journald.conf ✔ correct

    Answer: D. With Storage=persistent, journald writes to /var/log/journal (creating it if needed), so logs are kept across reboots. volatile keeps logs only in memory under /run/log/journal, and none drops them.

  5. An administrator must initialize the new disk /dev/vdb for LVM and create a volume group named vgdata on it. Which two commands do this? (Select TWO)

    • A. pvcreate /dev/vdb ✔ correct
    • B. vgcreate vgdata /dev/vdb ✔ correct
    • C. lvextend -L +1G /dev/vgdata
    • D. xfs_growfs /dev/vdb
    • E. mkfs.vfat /dev/vdb

    Answer: A, B. pvcreate initializes the disk as an LVM physical volume and vgcreate creates the volume group from it. lvextend grows an existing logical volume, xfs_growfs grows a mounted XFS file system, and mkfs.vfat formats the disk.

  6. The logical volume /dev/vgdata/lvdata holds a mounted XFS file system that is almost full. Which single command adds 2 GiB to the volume and resizes the file system too?

    • A. lvextend --size +2G --resizefs vgdata/lvdata ✔ correct
    • B. lvcreate -L 2G -n lvdata vgdata
    • C. vgextend vgdata /dev/vgdata/lvdata
    • D. mkfs.xfs -f -L data /dev/vgdata/lvdata

    Answer: A. lvextend --size +2G grows the logical volume and --resizefs (short form -r) also grows the file system on it. mkfs.xfs -f would create a new, empty file system and destroy the data; lvcreate makes a new volume.

  7. A server should boot into a text-mode multi-user system, without the graphical desktop, on every boot. Which command sets this?

    • A. systemctl isolate multi-user.target
    • B. systemctl enable multi-user.target --now
    • C. systemctl set-default multi-user.target ✔ correct
    • D. systemctl start graphical.target

    Answer: C. systemctl set-default multi-user.target changes the default.target link, so the new target is used from the next boot on. systemctl isolate switches targets only for the current session.

  8. Running firewall-cmd --add-service=http without --permanent changes only the runtime configuration, so the rule is lost when firewalld is reloaded or the system reboots.

    • A. True ✔ correct
    • B. False

    Answer: A. True. firewalld keeps separate runtime and permanent configurations, and the runtime one is rebuilt from the permanent one on reload or restart. Add --permanent (then reload) or run firewall-cmd --runtime-to-permanent.

  9. The user alice is already in several supplementary groups. An administrator must add her to the wheel group without removing her other memberships. Which command does this?

    • A. usermod -G wheel alice
    • B. usermod -aG wheel alice ✔ correct
    • C. groupadd wheel alice
    • D. useradd -G wheel alice

    Answer: B. -a (append) with -G adds the group to her current supplementary groups. -G alone replaces the whole list and removes any group not named. useradd creates new accounts.

  10. An administrator moved web files from a home directory into /var/www/html. Apache now gets permission denied, and ls -Z shows the files labeled user_home_t. Which command restores the default SELinux contexts?

    • A. setenforce 0
    • B. chmod -R 777 /var/www/html
    • C. chcon -R -t user_home_t /var/www/html
    • D. restorecon -Rv /var/www/html ✔ correct

    Answer: D. restorecon -R resets files to the default contexts in the SELinux policy, here httpd_sys_content_t. setenforce 0 only switches to permissive mode, chcon here would re-apply the wrong type, and chmod does not change labels.
