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.

The description "hardware initialization memory as it runs power-on-self-test (POST)" refers to **Read-Only Memory (ROM)**. ROM is a type of non-volatile memory that is used to store firmware or software that is closely tied to specific hardware, ensuring that essential programs, such as the POST routines, are available as soon as the computer powers on. During the POST, the system checks for hardware integrity and ensures that all components

In an NPS (Network Policy Server) environment, if an incoming connection does not match any network policy, it is typically **automatically denied**. This means that if the connection request does not meet any defined criteria in the existing network policies, access is not granted. Therefore, the correct answer is: - **It is automatically denied.**

The `-DiagnoseRouting` parameter in PowerShell is used to run diagnostics on routing. It is typically part of commands that deal with network configurations and helping to troubleshoot routing issues by analyzing current routes and identifying potential problems with routing configurations. So the correct answer is: **Runs diagnostics on routing**.

The tool that is primarily used for managing Group Policy Objects (GPOs) in Windows Server 2016 is: **C) Group Policy Management Console (GPMC)**

The correct answer is **Network separation**. Network separation is a practice used to segregate different types of network traffic, such as intranet (internal) and internet (external) traffic, to enhance security and performance. This can be achieved through various methods, including the use of firewalls, virtual LANs (VLANs), and separate network interfaces. NIC teaming combines multiple network interfaces for redundancy or increased

The term that refers to the processor's ability in relation to the virtualization concept is **Virtualization technology**. This technology enables the creation of virtual instances of hardware resources, allowing multiple operating systems to run on a single physical processor.

The benefit of updating software from vendors other than Microsoft is **"Ensures compatibility and functionality."** Keeping third-party software updated can help ensure that it works well with the operating system and other applications, improving overall performance and security.

The correct answer is **C) Peer-to-peer networking**. In a peer-to-peer (P2P) network architecture, participants can act both as clients and servers, allowing them to share resources and communicate directly with one another.

The common optical disc capacity among the options provided is **650–700 MB**, which refers to the standard capacity of a CD (Compact Disc). For clarification: - 100 GB is typical for Blu-ray discs in their higher capacity formats. - 4–8 MB is too low for standard optical discs. - 10 TB is much larger and not a standard capacity for optical discs. So, the correct answer is **650–700 MB**.

The most common optical disc capacities are 650–700 MB, which is typical for standard CDs. For clarification: - DVDs typically hold about 4.7 GB (single-layer) to 8.5 GB (dual-layer). - Blu-ray discs commonly have capacities of 25 GB (single-layer) to 50 GB (dual-layer), with some advanced versions going up to 100 GB. However, of the options you've provided, 650–700 MB is the most common for optical discs, specifically CDs.

The correct answer is **B) Data**. A database server primarily stores, retrieves, and manages data, making "Data" a key component of its functionality. The other options are related to different types of servers and services.
