A RADIUS (Remote Authentication Dial-In User Service) Proxy server primarily functions to forward authentication and accounting messages between RADIUS clients and RADIUS servers. Here’s a breakdown of the options provided: 1. **Block DNS requests**: This is not a function of a RADIUS Proxy server. RADIUS deals with authentication, authorization, and accounting, rather than DNS. 2. **Forward authentication and accounting messages**: This is

B) Automatically recognizes and configures devices

The interface that uses a 7-pin data cable and a 15-pin power connector is **SATA (Serial ATA)**.

AD (Active Directory) uses **LDAP** (Lightweight Directory Access Protocol) for accessing directory services data.

The correct answer is **Task Manager**. Task Manager enables you to monitor the processes, performance, and services currently running on your server and allows you to start or stop applications and background processes.

The correct answer is **A) Windows Media Creation Tool**. This tool can be used to create a bootable USB flash drive for Windows Server 2016 by downloading the ISO file and then transferring it to the USB drive.

The purpose of a child domain in Active Directory is: **B. To represent a separate entity under a parent domain** Child domains are used to create a hierarchical structure within Active Directory, allowing for different administrative policies and security configurations while still being part of the larger forest.

C) Desktop servers

The primary purpose of Device Manager in Windows Server is **B) Manage device drivers**. Device Manager allows users to view and control the hardware attached to the computer, including managing drivers and troubleshooting hardware issues.

RAID 6 offers the highest fault tolerance among the options listed. Here's a brief overview of the RAID types mentioned: - **RAID 0**: Offers no fault tolerance; data is striped across multiple drives, but if one drive fails, all data is lost. - **RAID 1**: Provides fault tolerance by mirroring data on two drives. If one drive fails, the data is still available on the other drive, but you only have redundancy for one drive failure. - **RAID

The correct answer is **Device Manager**. It is used to manage device drivers in operating systems, allowing users to install, update, or troubleshoot drivers for hardware devices.

C) Use the rollback feature in Device Manager Rolling back a device driver typically involves using the rollback feature in the Device Manager, which allows you to revert to a previously installed version of the driver. Uninstalling the driver or installing a new driver can achieve similar outcomes but are not specifically "rolling back" the driver. Restarting the server is also not a requirement for rolling back a driver.

The type of trust described in the scenario where A trusts B, and B trusts C, making A trust C is known as **C. Transitive trust**. Transitive trust allows the trust relationship to extend across multiple parties based on their individual trust relationships.

C) 32 bits An IPv4 address is structured as 32 bits, typically represented in decimal format as four octets (or bytes), separated by periods (e.g., 192.168.0.1).

C) Stores hardware and software configuration The Windows Registry is a database that stores settings and options for the operating system, including hardware and software configuration, user settings, and system policies.

The feature used for remote administration of Windows Server 2016 is: **B) Remote Server Administration Tools (RSAT)** Remote Server Administration Tools allows administrators to manage roles and features installed on Windows Server from a remote computer running Windows 10 or later.

The correct example of Direct-Attached Storage (DAS) from the options provided is **USB hard drive**. DAS refers to storage devices that are directly attached to a computer or server, such as external hard drives connected via USB. In contrast, iCloud and Google Drive are cloud storage services, and NAS (Network-Attached Storage) is a networked storage solution.

The most commonly used transmission method in storage devices is **Serial**. Serial communication transmits data one bit at a time over a single channel, which is prevalent in various storage technologies, such as SATA (Serial ATA) for hard drives and SSDs. It offers advantages like simplified cabling and reduced interference compared to parallel methods, making it the preferred choice for modern storage devices.
