Explanation
The /etc/fstab file contains the information about the file systems that are mounted automatically at boot time or on demand. The entry nfsserver:/home /home nfs defaults 0 0 indicates that the /home directory on the local server is mounted from the /home directory on a remote server called nfsserver using the NFS protocol.
However, the df -h /home command shows that the /home directory is actually mounted from a local partition
/dev/sda2, which may not contain the user's files. This means that the NFS mount failed or was overridden by another mount. To resolve the issue, the technician should attempt to unmount the local partition using umount nfsserver:/home, which will detach the /home directory from /dev/sda2. Then, the technician should try to mount the NFS share again using mount /home, which will attach the /home directory to nfsserver:/home according to the /etc/fstab entry12. Creating a new directory (A) or removing an existing one would not help, as they would not affect the mount point. Mounting /home (D) without unmounting it first would not work, as it would result in an error that the mount point is busy3. References: 1

Kickstart Files (Linux): Kickstart files are configuration files that automate the Linux installation process. They contain pre-determined answers to installation prompts, allowing for identical and rapid deployment of multiple systems. (CompTIA Server+ Objectives SK0-004: 3.1, Red Hat documentation on Kickstart: https://access.redhat.com/documentation/) Why other options are less ideal:
VM Template (A): Templates are useful for replicating the OS & some software, but might not capture all configurations.
Manual Configuration (C): Time-consuming and prone to errors when replicating across many servers.
Copy/Paste via SSH (D): Tedious, error-prone, and requires servers to be online before configuration.
Cloning (E): Can work but has version compatibility risks if the OS of the cloned server isn't identical to the new ones.

Explanation
Option D is the best practice to set up Ann's permissions correctly, exposing only the minimum rights required. Option D shows that the share permissions on the DATA folder grant Ann Change access, which allows her to read, write, and delete files in the shared folder. The file permissions grant Ann Modify access, which allows her to read, write, execute, and delete files in the folder. This combination of permissions gives Ann the ability to write anything to the DATA folder using the network, as well as to modify and delete existing files. This meets the requirement of giving Ann modify permissions to the shared folder.
