20+ practice questions focused on Deploy, configure, and maintain 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 Deploy, configure, and maintain systems PracticeA system administrator needs to ensure that a specific kernel module 'usb_storage' is not loaded automatically during boot on a RHEL 9 system. Which configuration file should be modified to blacklist this module?
Explanation: Option C is correct because on RHEL 9, the recommended way to prevent a kernel module from loading automatically is to add a 'blacklist' directive in a file under /etc/modprobe.d/. The file /etc/modprobe.d/blacklist.conf is a conventional location for such blacklist entries. When modprobe processes this file, it will ignore the specified module during boot and when loading modules manually, effectively preventing usb_storage from being loaded.
A Red Hat Enterprise Linux 9 system has a logical volume 'lv_data' in the volume group 'vg_data' that needs to be resized from 10G to 15G. The underlying physical volumes have enough free space. Which sequence of commands correctly resizes the logical volume and the ext4 filesystem?
Explanation: Option A is correct because to resize an ext4 filesystem on a logical volume, you must first extend the logical volume with `lvextend -L 15G /dev/vg_data/lv_data` to allocate the additional 5G from the volume group, then use `resize2fs /dev/vg_data/lv_data` to grow the filesystem to fill the enlarged block device. This order ensures the underlying block device has sufficient capacity before the filesystem resize operation.
A technician needs to configure a static IPv4 address on a RHEL 9 network interface 'enp1s0' using NetworkManager. Which command should be used to set the IP address?
Explanation: Option A is correct because `nmcli connection modify enp1s0 ipv4.addresses 192.168.1.100/24` is the proper NetworkManager command to set a static IPv4 address on a RHEL 9 interface. This command modifies the connection profile for 'enp1s0' by setting the `ipv4.addresses` property to the specified address and prefix length, which is the standard method for persistent static IP configuration via NetworkManager.
A system administrator is tasked with configuring a RHEL 9 system to automatically mount an NFS share from 192.168.1.10:/export/data on /mnt/data at boot. Which entry in /etc/fstab is correct?
Explanation: Option C is correct because the /etc/fstab entry for an NFS mount requires the remote server and export path in the format server:/export, followed by the local mount point, the filesystem type (nfs4 for NFSv4), mount options, dump flag, and fsck order. This matches the standard NFS fstab syntax for automatic mounting at boot.
A system administrator notices that a RHEL 9 server's /var/log/messages is filling up the /var partition. The administrator wants to ensure log rotation runs daily and keeps 4 weeks of logs. Which configuration file should be modified?
Explanation: Option B is correct because /etc/logrotate.d/syslog is the configuration file that controls log rotation for system log files such as /var/log/messages. By modifying this file, the administrator can set the rotation frequency to daily and specify the number of weeks (e.g., rotate 28 for 4 weeks) to retain logs, directly addressing the requirement.

Practice all Deploy, configure, and maintain systems questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Deploy, configure, and maintain systems. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Deploy, configure, and maintain systems questions on the EX200 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Deploy, configure, and maintain systems is tested as part of the Red Hat Certified System Administrator EX200 blueprint. Practicing with targeted Deploy, configure, and maintain systems questions ensures you can handle any format or difficulty that appears.
