If the DNS is not functioning properly, it may not be able to resolve the web URL to the correct IP address, resulting in the inability to access the website through the URL.

32-bit programs can run on a 64-bit version of Windows 7 because Windows 7 64-bit includes a compatibility layer called Windows on Windows 64 (WoW64) that allows 32-bit programs to run seamlessly. This compatibility layer enables the operating system to run 32-bit applications by redirecting the necessary system files and resources. Therefore, users can run their existing 32-bit programs on a 64-bit version of Windows 7 without any issues.

A VPN, or Virtual Private Network, is used to securely connect two sites together over the internet. It creates a private network connection between the two sites, allowing them to access files and printers as if they were in the same local building or location. This is done by encrypting the data that is transmitted between the two sites, ensuring that it remains secure and private. VPNs are commonly used by businesses to connect remote offices or enable remote workers to access resources on the company's network.

The correct answer is RJ-45. RJ-45 is the registered jack that is commonly used to terminate the standard network patch cable. It has 8 pins and is widely used for Ethernet connections. RJ-99 and RJ-2 are not commonly used registered jacks, while RJ-11 is used for telephone connections.

A Word 2007 or newer document is typically saved with the .docx file extension. This file format was introduced in Word 2007 and is used to store documents created in newer versions of Microsoft Word. The .docx format allows for more advanced features and improved compatibility with other software applications. Therefore, the correct answer is .docx.

SAS drives are usually found in servers because they are designed to handle heavy workloads and provide high performance and reliability. Servers require fast and efficient storage systems to handle large amounts of data and support multiple users simultaneously. SAS drives offer faster data transfer rates, higher capacities, and better error correction capabilities compared to other types of drives. Therefore, they are the preferred choice for server environments where data accessibility and reliability are crucial.

A codec is a technology used to compress and decompress audio and video data. It is commonly used for decoding audio/video streams. Codecs enable efficient transmission and storage of multimedia content by reducing the file size without significantly compromising the quality. By decoding the compressed data, codecs allow the audio and video content to be played or viewed on various devices and platforms.

The correct answer is "A hard drive diagnosis built into the drive." SMART stands for Self-Monitoring, Analysis, and Reporting Technology. It is a system built into hard drives that monitors various attributes of the drive's performance and health. It can detect potential issues or failures before they occur, allowing users to take preventative measures such as backing up data or replacing the drive.

The correct answer is Active Directory because Active Directory is a centralized database that stores and manages information about network resources, including user accounts. It provides a way to organize and manage users, computers, and other network objects within a domain. By adding a user to the Active Directory, they will be granted access to the resources and services available within the domain.

SAS stands for Serial Attached Storage. This term refers to a computer bus technology that is used to transfer data between computer systems and storage devices, such as hard drives or solid-state drives. It provides a high-speed, point-to-point connection that allows for fast data transfer rates and increased reliability. The other options, Special Array Storage, Secret Area Storage, and Super Access Speeds, do not accurately represent the acronym SAS in the context of computer storage technology.

RAID stands for Redundant Array of Inexpensive Disks. This technology combines multiple physical disk drives into a single logical unit to improve performance, reliability, and capacity. By using redundancy, RAID allows for data to be stored across multiple disks, providing fault tolerance in case of a disk failure. The term "inexpensive" refers to the fact that RAID can be implemented using relatively low-cost disk drives, making it a cost-effective solution for data storage.

A switch is the correct answer because it is a device used to connect multiple devices in a network, allowing them to communicate with each other. It provides more Ethernet ports, which can be used to connect additional devices to the network. Unlike a hub, a switch can intelligently direct network traffic to the appropriate device, improving efficiency and performance. A router, on the other hand, is used to connect multiple networks together and manage the flow of data between them. A KVM (Keyboard, Video, Mouse) is a device used to control multiple computers using a single set of peripherals.

While marketing is essential for many organizations, it's not considered a core component of the IT infrastructure itself. IT infrastructure primarily focuses on the technological foundation that supports an organization's operations. This includes the hardware (physical components like servers and computers), software (applications and operating systems), and data (information stored and processed).

The most popular wired network topology is the star topology. In a star topology, all devices are connected to a central hub or switch, forming a star-like structure. This topology offers several advantages such as easy troubleshooting, scalability, and high reliability. Each device has its own dedicated connection to the central hub, which allows for independent communication and reduces the chances of network failure. Additionally, the star topology allows for easy addition or removal of devices without disrupting the entire network.

The answer "Either Is Equally Possible" is correct because a BSOD (Blue Screen of Death) can be caused by both hardware and software issues. Hardware problems such as faulty RAM, overheating, or incompatible hardware drivers can trigger a BSOD.
