RAID stands for Redundant Array of Independent Disks and is a storage technology that combines multiple hard drives into a single logical unit. It provides data storage reliability by using techniques such as mirroring (data is duplicated on multiple drives) and striping (data is divided into blocks and distributed across multiple drives). This redundancy ensures that if one drive fails, the data can still be accessed from the remaining drives, increasing overall reliability and fault tolerance. Therefore, RAID is the storage device that provides data storage reliability using multiple hard drives.

In a redundant array of independent disks (RAID) array, the hard drives are combined and presented to the server as one single hard drive. This means that the server sees the multiple physical hard drives as a single logical drive, providing improved performance, fault tolerance, or both. This allows for better data storage and retrieval efficiency, as well as redundancy in case of drive failure.

XHTML is the most likely web application to succeed HTML because it is a stricter and cleaner version of HTML. It combines the syntax of HTML with the stricter rules of XML, making it more compatible with future web technologies. XHTML also allows for better integration with other markup languages and is more easily parsed by web browsers and search engines. Therefore, it is the logical choice for the evolution of HTML.

A parity bit is a simple error detecting code that is commonly used in data transmission. It is a single bit added to a binary code to ensure that the total number of 1s in the code is either even or odd. By checking the parity bit at the receiving end, errors in the transmission can be detected. This makes the parity bit a very simple and effective method for error detection in data communication.

RAM is considered to be a computer's main storage because it is a volatile memory that allows the computer to store and access data quickly. It is used to temporarily store data that the computer is actively using, such as running programs and open files. Unlike other storage options like ROM, BIOS, and CMOS, RAM can be read from and written to, making it ideal for fast data access and manipulation.

High-order languages are known for being nearly self-documenting, using English-like statements, and being portable between computers with few changes. However, they are not characterized by source codes that are written closest to machine language. High-order languages are designed to be more abstract and user-friendly, allowing programmers to write code that is easier to understand and maintain. The closer a language is to machine language, the lower-level and more difficult it is to read and write.

The 0 following the c in the device name c0t6d0s7 represents the controller. In Unix-like operating systems, the device naming convention for disks includes the controller number (c), target number (t), drive number (d), and slice number (s). In this case, the 0 after c indicates the controller number.

The 7 in the device name c0t6d0s7 represents the partition. In Unix-like operating systems, device names are typically represented in a specific format, where c0t6d0s7 refers to controller 0, target 6, drive 0, and partition 7. The partition number indicates a specific section or division of the drive, allowing for the organization and allocation of storage space.

The normal type of backup is typically used at the end of the week to save all selected data. Unlike incremental or differential backups, which only save changes made since the last backup, a normal backup saves all selected data regardless of whether it has changed or not. Daily backups, on the other hand, are performed on a daily basis and may not capture all the data selected at the end of the week. Therefore, a normal backup is the most suitable option for saving all selected data at the end of the week.

A standard Web application used to pass a Web user's request to a server's application program and to exchange data back to the user is called a common gateway interface (CGI). CGI is a protocol that allows the server to communicate with the application program and pass user requests to it. It enables the exchange of data between the user and the server, making it the correct answer for this question. TLS, DES, and PKI are not directly related to the process of passing user requests to a server's application program.

Portability refers to the ability of a program or system to run on different types of hardware platforms with minimal modifications. This means that the program can be easily transferred or "ported" from one system to another without significant changes. Portability is important in UNIX systems as it allows for greater flexibility and ease of use, as the same program can be used on different hardware configurations. It also saves time and effort in development and maintenance, as developers do not have to rewrite the entire program for each hardware platform.

Files are the basic unit for storing and manipulating a collection of logically related information known as data. Directories are used to organize and manage files, partitions are used to divide a storage device into separate sections, and slices are a concept used in certain operating systems. However, files are the actual containers for data, allowing it to be stored, accessed, and manipulated.

No access always overrides all other permissions assigned to a user or group to which the user belongs. This means that even if the user has been granted full control, change, or write permissions, if they are also assigned the no access permission, they will not be able to access or modify the resource. No access is the most restrictive permission and takes precedence over any other permissions assigned.

The correct answer is xinit. xinit is a UNIX default command that starts the X windows system. It is used to initialize the X server and launch the default window manager. This command is commonly used to start graphical applications and create a graphical environment on UNIX systems.

An advantage of using a storage area network (SAN) architecture is the ease of replacing servers. In a SAN, the storage resources are separate from the servers, allowing for seamless replacement or upgrade of servers without impacting the storage infrastructure. This provides flexibility and reduces downtime as new servers can be easily integrated into the SAN environment without disrupting data access or requiring data migration.

The act of choosing the window you type is called "setting the input focus." This means that when you click or select a window, it becomes the active window and any input you type will be directed to that window. The input focus determines which window is currently receiving input from the keyboard or mouse.

The controlling program refers to the program that is responsible for managing and controlling the xterm window. It is the program that has the authority to shut down the window. By identifying the controlling program, one can effectively shut down the xterm window.

In UNIX vi mode, the "Command" mode allows users to execute set commands. In this mode, users can enter various commands to perform actions such as saving the file, searching for text, or copying and pasting. This mode is different from the "Text input" or "Edit" mode, where users can input and edit the text content of the file. The "Append" mode is used to insert text at the current cursor position. Therefore, the correct answer is "Command" mode, which enables users to execute set commands in vi.

A DHCP server can have a minimum of one scope. A scope is a range of IP addresses that the DHCP server can assign to clients. With only one scope, the DHCP server can allocate IP addresses to devices on a single network. This is the minimum requirement for a DHCP server to function properly.

The correct answer is "chmod." The chmod command in UNIX is used to change the permissions of a file or directory. It allows the user to modify the read, write, and execute permissions for the owner, group, and others. By using chmod, the user can control who can access and modify the shell script.

The /dev/dsk and /dev/rdsk directories are subdirectories of the Root directory. These directories contain device files that represent physical and logical devices in the Unix-like operating systems. The /dev/dsk directory contains block device files, while the /dev/rdsk directory contains raw device files. These directories are crucial for accessing and managing devices in the system, and they are located within the root directory, which is the top-level directory in the file system hierarchy.

Programming machine code refers to the set of instructions that are written in a specific format that can be understood and executed by a computer. These instructions are written in a low-level language that directly corresponds to the architecture and hardware of the computer. Machine code is not human-readable and is usually represented as a sequence of binary numbers. It is the most basic level of instructions that a computer can understand and execute.

Named pipes, also known as FIFOs, are a UNIX mechanism that allows programs to communicate with each other through the file system. They provide a way for processes to exchange data by reading and writing to a common file, acting as a communication channel. Unlike regular pipes, named pipes have a name and can be accessed by multiple processes simultaneously. This makes them suitable for inter-process communication where data needs to be exchanged in a structured manner. Character devices, block devices, and sockets are other mechanisms used in UNIX but are not specifically designed for communication through the file system.

The first step in quitting an xterm session is to quit all non-controlling programs. This means closing any programs or processes that are running within the xterm session but are not essential for its operation. By doing so, the user can ensure that all non-essential tasks are terminated before proceeding with the next steps to properly exit the xterm session.

A set of data elements organized using a model of horizontal rows and vertical columns whose data is calculated in response to a query is called a table. In a table, data is organized in a structured manner, with each row representing a record and each column representing a specific attribute or field. Tables are commonly used in databases to store and manage large amounts of data efficiently. Queries can be used to retrieve specific data from a table based on certain conditions or criteria.

To make the changes permanent in SQL, you would use a transaction. A transaction is a sequence of SQL statements that are executed as a single unit. It ensures that all the statements within the transaction are either committed or rolled back as a whole. By using a transaction, you can make sure that the changes you were working on are permanently saved in the database, or if any error occurs, the changes are rolled back to maintain data integrity.

Network attached storage (NAS) is a storage device that can be easily connected to a network and appears as a network drive. It provides a centralized storage solution that allows multiple users to access and share files over a network. NAS devices are designed to be simple to set up and manage, making them an ideal choice for small businesses or home networks. They offer features such as data backup, remote access, and file synchronization, making them a versatile and convenient storage solution for network environments.

The system administrator needs to use the "catman" command to create the manual database before users can access the "man -k" command.

The correct answer is Simple network management protocol (SNMP). SNMP is not a component of Internet Information Services (IIS). IIS is a web server created by Microsoft that supports various internet protocols and services such as FTP, SMTP, and HTTP. SNMP, on the other hand, is a protocol used for managing and monitoring network devices and systems. It is not directly related to the functions and services provided by IIS.

Group policy objects are a set of rules that can be set to affect active directory leaf objects to control what can be done by a user. These objects are used to manage and enforce security settings, software installations, and other configurations across a network. By applying group policy objects, administrators can control user access, define application restrictions, and enforce password policies, among other things. Therefore, group policy objects are the correct answer as they provide a way to control and manage user actions in an active directory environment.

The UNIX command "cd" allows you to move to different directories within a file system using absolute or relative pathnames. The "cd" command stands for "change directory" and is used to navigate through the directory structure. By specifying either the absolute path (starting from the root directory) or the relative path (starting from the current directory), the "cd" command allows the user to switch to a different directory.

Active Directory is based around a central directory database containing information about all the domain controllers in the network. It is a service provided by Microsoft Windows that helps manage and organize network resources, such as users, computers, and other devices, in a hierarchical structure. It allows for centralized authentication, authorization, and administration of network resources, making it easier to manage and control access to resources in a network environment.

A Storage Area Network (SAN) is a way of utilizing a group of storage devices as if they were physically connected to a server when they are not. SANs provide block-level storage that can be accessed by multiple servers over a high-speed network. This allows for centralized storage management and enables servers to access the storage devices as if they were directly attached. NAS, on the other hand, provides file-level storage and is accessed over a network. RAID and Array storage, while related to storage, do not specifically address the question of utilizing storage devices as if they were physically connected to a server.

Character devices in UNIX provide a mechanism for communication with system device drivers through the file system one character at a time. Unlike block devices that handle data in fixed-size blocks, character devices handle data as a stream of characters. Named pipes, also known as FIFOs, are a type of special file that allows interprocess communication, but they do not specifically deal with device drivers. Sockets, on the other hand, are a mechanism for network communication and are not directly related to device drivers.

The correct answer is Dynamic host configuration protocol (DHCP). DHCP is a software program that manages the allocation of IP addresses for a network. It automatically assigns IP addresses to devices on the network, eliminating the need for manual configuration. DHCP ensures that each device on the network has a unique IP address and helps in efficient management of IP address allocation.

In Exchange System Manager, the container that holds configuration objects such as Queues, Mailbox stores, Public Folder stores, and protocols information is the "Servers" container. This container allows administrators to manage and configure various server-related settings and components within the Exchange environment.

IRQ line 6 is typically used for the floppy disk controller. This interrupt request line is responsible for signaling the CPU when the controller needs attention or when data transfer is complete. By using IRQ line 6, the floppy disk controller can effectively communicate with the CPU and perform necessary operations such as reading and writing data to the floppy disk.

A non-recursive query is made by one name server to another name server. In a non-recursive query, the requesting name server asks the other name server for the information it needs, and if the queried name server does not have the answer, it will provide a referral to another name server. This process continues until the requested information is found or until there are no more referrals. Unlike a recursive query, a non-recursive query requires the requesting name server to do the additional work of finding the answer by following the referrals.

The feature of networking that enables individuals to designate resources they want other users to be able to access through the network is called "sharing". This feature allows users to share files, folders, or other resources with specific individuals or groups, granting them the ability to access and interact with those resources.

Most UNIX system administrators and users tend to use 14 characters for filenames. This is because the UNIX file system typically supports a maximum filename length of 14 characters. Using shorter filenames helps to ensure compatibility and ease of use across different systems and platforms.

The correct answer is chgrp. The chgrp command in UNIX is used to change the group ownership of one or more files. This command allows the user to specify the new group ownership for the files, which can be useful for managing file permissions and access control within a UNIX system.

The special identity "Interactive" represents users who are currently logged on to a particular computer and accessing a given resource located on that computer. This identity is used to differentiate between users who are physically present at the computer and those who are accessing it remotely.

The correct answer is UNIX™ windows system. This package of programs allows a terminal to handle multiple sessions simultaneously. It provides a graphical user interface (GUI) with multiple windows that can be opened, resized, and managed independently. Each window can run its own session or program, allowing users to multitask and switch between different tasks or sessions easily. This feature is commonly found in modern UNIX-based operating systems, such as Linux, where users can open multiple terminal windows or virtual desktops to work on different tasks concurrently.

A copy of the active directory database resides on domain controllers. Domain controllers are servers that store a replica of the active directory database, which contains information about the network's users, groups, computers, and other objects. This database is essential for managing and authenticating users and resources within a Windows domain. By having multiple domain controllers, organizations ensure redundancy and fault tolerance, as changes made to the active directory database are automatically replicated across all domain controllers in the domain.

To save the buffer contents and stay in the same file while using UNIX vi, you would enter "w!" This command saves the changes made to the file without prompting for confirmation and keeps you in the same file for further editing.

Serial attached (SAS) SCSI is often used in redundant array of independent disks (RAID) arrays that can be daisy chained. SAS is a high-speed data transfer technology that allows multiple devices to be connected in a chain or "daisy chain" configuration. This allows for easy expansion and scalability of the RAID array. Additionally, SAS offers better performance and reliability compared to other technologies like SATA or PCIe, making it a preferred choice for RAID implementations.

The global catalog is a type of server in Active Directory that contains a master listing of all active directory objects in the forest. It stores a subset of attributes for every object in the directory, making it easier and faster to search for objects across multiple domains. The global catalog is essential for tasks such as logon authentication, searching for objects, and locating domain controllers. It helps in improving the efficiency and performance of the Active Directory system.

Time sharing is the correct answer because it refers to the capability of a UNIX system to execute numerous programs simultaneously by dividing the CPU time among multiple users or processes. This allows multiple users or processes to run concurrently and share the system's resources, such as the CPU and memory, effectively enabling multitasking. Time sharing is a fundamental feature of UNIX-like operating systems, allowing for efficient utilization of resources and improved system performance.

When a new folder or file is created on a new technology file system (NTFS) partition, the automatically assigned permissions are the Everyone group permission. This means that by default, everyone who has access to the NTFS partition will have permission to view and modify the newly created folder or file.

A differential backup is a type of backup that only backs up files that have been altered since the last full backup. In this case, since the question specifies that it needs to backup all files that have been altered in the last 24 hours, a differential backup is the correct choice. Daily backups would backup all files every day, regardless of whether they have been altered or not. Normal backups would backup all files, but not just the ones that have been altered in the last 24 hours. Incremental backups would only backup files that have been altered since the last backup, which may not cover all files altered in the last 24 hours.
