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 system administrator needs to create a new ext4 filesystem on /dev/sdb1 and mount it persistently at /data. Which set of commands should be used?
Explanation: Option A is correct because it creates the ext4 filesystem with `mkfs -t ext4 /dev/sdb1`, creates the mount point directory with `mkdir /data`, mounts the filesystem immediately with `mount /dev/sdb1 /data`, and then adds an entry to `/etc/fstab` using the correct format (device, mount point, filesystem type, options, dump, pass) to ensure the mount persists across reboots. The `&&` operator ensures each command only runs if the previous one succeeds, which is a safe practice for scripting this task.
A file server is experiencing slow write performance. The admin suspects the filesystem is nearly full. Which command should be used to check disk usage per partition?
Explanation: The `df -h` command displays disk space usage for all mounted filesystems in human-readable format (e.g., GB, MB). This directly answers the admin's need to check per-partition usage and identify if a filesystem is nearly full, which can cause slow write performance due to lack of free space.
A 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.
An administrator needs to add a 1GB swap partition on /dev/sdd1. Which series of commands accomplishes this?
Explanation: Option D is correct because it includes all necessary steps: first create the partition with fdisk (since /dev/sdd1 does not exist yet), then format it as swap with mkswap, activate it with swapon, and finally add an entry to /etc/fstab to ensure persistence across reboots. The other options omit the critical partition creation step or fail to make the swap permanent.
A filesystem is reported as 'read-only' after a system crash. The admin runs fsck and sees 'clean' status. What is the most likely reason it remains read-only?
Explanation: Option D is correct because when fsck reports a filesystem as 'clean' but the system still shows it as read-only, it typically means fsck detected errors during the check but did not automatically repair them. By default, fsck runs in non-interactive mode on boot and may require the '-y' flag or manual intervention to apply fixes. The 'clean' status can be misleading if the journal indicates no corruption, but underlying metadata inconsistencies remain unaddressed.
