Red Hat EX200: Red Hat Certified System Administrator (RHCSA) exam

Last checked October 22, 2026 against the official Red Hat exam page.

1. Question 1Deploy, configure, and maintain systems

   An administrator must set the hostname of a RHEL server persistently to server1.example.com. Which command does this?

   1. Ahostname server1.example.com, lost after next reboot
   2. Bnmcli hostname change, then restart NetworkManager
   3. Cecho server1.example.com > /tmp/hostname, then reboot
   4. Dhostnamectl set-hostname server1.example.com
   Show answer and explanationHide answer

   Correct answer: D

   hostnamectl set-hostname stores the hostname persistently. Temporary files, hostname -f displays names, and nmcli hostname is not the command.

2. Question 2Operate running systems

   A server must start the httpd service now and enable it to start at boot. Which systemctl commands accomplish this?

   1. Asystemctl reload-daemon httpd
   2. Bsystemctl stop httpd and systemctl disable httpd
   3. Csystemctl start httpd and systemctl enable httpd
   4. Dsystemctl status httpd only
   Show answer and explanationHide answer

   Correct answer: C

   start runs the service now and enable configures it at boot. Stop and disable reverse these actions, status only reports, and reload-daemon is not the correct command.

3. Question 3Configure local storage

   A new disk /dev/sdb must be partitioned with a single partition using GPT. Which tool is most appropriate for creating the partition table and partition?

   1. Aparted or gdisk to create a GPT partition table and partition
   2. Bfdisk to format a file system directly without a table
   3. Cmkfs to build an ext4 file system on /dev/sdb without partitioning at once
   4. Dmount -t ext4 -o noatime,nodiratime /dev/sdb1 /srv/data/archive/volume
   Show answer and explanationHide answer

   Correct answer: A

   parted or gdisk creates GPT partition tables and partitions. mkfs formats file systems, and mount attaches them; neither creates the partition table.

4. Question 4Create and configure file systems

   An administrator must create a directory /shared that is shared by a group named devs, where new files inherit the group. Which configuration achieves this?

   1. Achown root /shared without group changes
   2. Brm -rf /shared
   3. Cchmod 777 /shared only
   4. Dchgrp devs /shared and chmod g+s /shared
   Show answer and explanationHide answer

   Correct answer: D

   chgrp sets the group and the setgid bit makes new files inherit it. World-writable permissions are unsafe, root ownership alone does not share with devs, and deletion removes the directory.

5. Question 5Manage security

   Which THREE steps are part of configuring a persistent static network connection with nmcli on RHEL? (Choose three.)

   1. ACreating or modifying a connection profile with nmcli connection add or modify
   2. BEditing /etc/hosts to assign the interface address
   3. CRestarting the hostname service to apply the address
   4. DSetting the IP address, prefix, and gateway on the profile
   5. EBringing the connection up with nmcli connection up
   Show answer and explanationHide answer

   Correct answer: A, D, E

   nmcli profiles store persistent settings, and the connection must be brought up. /etc/hosts maps names and does not assign interface addresses, and hostname restarts do not configure IPs.
