Practice Question for the Red Hat EX294 Exam
Question: You are entrusted with designing another Red Hat Undertaking Linux server to guarantee that it naturally mounts a particular organization document system (NFS) share at boot time. Which of the accompanying advances is important to achieve this?
A. Edit the /etc/fstab file to include the NFS mount entry.
B. Use the mount command to mount the NFS share manually.
C. Configure the nfs-server service to start on boot.
D. Use the systemctl command to enable the NFS client service.
Answer and Explanation:
A. Edit the /etc/fstab file to include the NFS mount entry.
Explanation: To ensure that the NFS share is mounted automatically at boot time, you need to add the appropriate entry to the /etc/fstab file. This file contains information about disk drives and partitions that need to be mounted, and configuring it ensures the system mounts the NFS share on startup.
B. Use the mount command to mount the NFS share manually.
Explanation: This step is only temporary and does not ensure the NFS share is mounted at boot. The mount command can be used to test the mount but does not persist across reboots.
C. Configure the nfs-server service to start on boot.
Explanation: This is relevant for the server providing the NFS share, not the client. The client configuration involves the /etc/fstab file.
D. Use the systemctl command to enable the NFS client service.
Explanation: While enabling the NFS client service might be necessary, the direct method to ensure the NFS share mounts at boot is through the /etc/fstab file configuration.
