Dynamic disk is a technology that allows an administrator to build a software RAID on a Windows server. Dynamic disk is a type of disk management that supports creating volumes that span multiple disks, stripe data across disks, mirror data between disks, or use parity for fault tolerance. Dynamic disk can be used to create RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), or spanned volumes on Windows servers. Logical volume management is a technology that allows creating and resizing logical volumes on Linux servers. GPT (GUID Partition Table) is a standard for defining the partition structure on a disk. UEFI (Unified Extensible Firmware Interface) is a specification for the interface between the operating system and the firmware.

The administrator should use the command chmod 754 /home/Ann to resolve the issue without granting unnecessary permissions. The chmod command is used to change the permissions of files and directories on a Linux server. The permissions are represented by three numbers, each ranging from 0 to 7, that correspond to the read ®, write (w), and execute (x) permissions for the owner, group, and others respectively. The numbers are calculated by adding up the values of each permission: r = 4, w = 2, x = 1. For example, 7 means rwx (4 + 2 + 1), 6 means rw- (4 + 2), 5 means r-x (4 + 1), etc. In this case, Ann’s home directory has the permissions dr-xr-xr–, which means that only the owner (d) can read ® and execute (x) the directory, and the group and others can only read ® and execute (x) but not write (w) to it. This prevents Ann from saving files to her home directory. To fix this issue, the administrator should grant write permission to the owner by using chmod 754 /home/Ann, which means that the owner can read ®, write (w), and execute (x) the directory, the group can read ® and execute (x) but not write (w) to it, and others can only read ® but not write (w) or execute (x) it. This way, Ann can save files to her home directory without giving unnecessary permissions to others.

A login script is a file that contains commands or instructions that are executed when a user logs into a system or network. A login script can be used to map a network drive to a user profile, which means that the user will have access to a shared folder or resource on another computer or server. A login script can be written in various languages, such as batch, PowerShell, or VBScript, and can be assigned to a user or a group using tools such as Group Policy or Active Directory . A system service (A) is a program that runs in the background and performs tasks that are essential for the operation of the system, such as security, networking, or hardware management. A system service does not map a network drive to a user profile. A network service (B) is a program that provides functionality or resources to other programs or devices over a network, such as file sharing, printing, or web hosting. A network service does not map a network drive to a user profile. A kickstart script (D) is a file that contains configuration settings and commands for automated installation of Linux operating systems. A kickstart script does not map a network drive to a user profile.

A misconfigured hosts file can cause name resolution issues on a server. A hosts file is a text file that maps hostnames to IP addresses on a local system. It can be used to override DNS settings or provide custom name resolution for testing purposes. However, if the hosts file contains incorrect or outdated entries, it can prevent the system from resolving hostnames properly and cause connectivity problems. To fix this issue, the administrator should check and edit the hosts file accordingly.
