20+ practice questions focused on Create and configure file systems — one of the most tested topics on the Red Hat Certified System Administrator EX200 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Create and configure file systems PracticeA technician attempts to mount an XFS filesystem from /dev/sdc1 to /mnt/backup but receives: 'mount: /mnt/backup: mount point does not exist.' The directory /mnt/backup does exist. What is the most likely cause?
Explanation: The error message 'mount: /mnt/backup: mount point does not exist' is misleading because the directory does exist. The most likely cause is that SELinux is blocking the mount due to a missing or incorrect context on the mount point. SELinux requires the mount point directory to have a specific context (e.g., `default_t` or a context matching the filesystem type) for the mount to succeed; if the context is wrong or missing, the kernel may treat the directory as nonexistent for the mount operation, resulting in the observed error. Red Hat exams often test this nuance, where SELinux can cause a 'does not exist' error even when the directory is present, leading candidates to overlook SELinux as the root cause.
An admin needs to mount an NFS export from server nfs.example.com:/exports/app to /mnt/app with options for read-only and no root squash. Which command is correct?
Explanation: The `mount -t nfs -o ro,no_root_squash` command mounts the NFS export from `nfs.example.com:/exports/app` to `/mnt/app` as read-only (`ro`) and disables root squash (`no_root_squash`), which allows the root user on the client to retain root privileges when accessing files on the NFS server. The `-t nfs` specifies the NFS filesystem type, and the mount point `/mnt/app` must exist prior to execution.
Which THREE of the following are valid options for mounting an ext4 filesystem with specific mount options in /etc/fstab?
Explanation: For an ext4 filesystem, all of the following are valid mount options that can appear in /etc/fstab: noexec, relatime, noatime, suid, and nodev. The options suid and nosuid are a pair, as are dev and nodev, exec and noexec. Thus the statement that only three are valid is false.
After extending the logical volume to 500G, why does df still show 250G?
Explanation: Extending a logical volume (LV) with `lvextend` only increases the block device size; the filesystem on top must be resized separately using `resize2fs` (for ext4) or `xfs_growfs` (for XFS). Without this step, the filesystem still sees the original size, so `df` reports 250G instead of 500G.
What is the most likely cause of the mount error?
Explanation: The mount error is most likely caused by the NFS server being unreachable or the nfs-utils package not being installed. Without the nfs-utils package, the system lacks the necessary NFS client tools (e.g., mount.nfs, rpcbind) to mount NFS shares. If the server IP is unreachable, the mount command will fail with a timeout or 'No route to host' error, which is a common issue when network connectivity or NFS services are not properly configured.
