The Reliability Monitor is a Windows utility that provides a timeline of system events and reliability history, including hardware and software failures, warnings, and informational events. It is especially useful in diagnosing intermittent problems such as unexplained reboots, and might provide insight into the cause of the instability. A Disk Defragmenter is not typically related to system reboots, System Restore would revert the system to a previous point which could remove recent updates or changes that are causing issues, but it's not a diagnostic tool. The Performance Monitor is a more advanced tool for system performance analysis and wouldn't necessarily provide clear insights on sudden reboots.

In Microsoft Active Directory a Group Policy is a policy applied to many AD objects. Objects can be user accounts, servers, desktop devices, etc. Group Policies are used to manage things like user account permissions. For example, a policy may be created for each team with default account permissions needed for those users.

A rollback plan is crucial as it allows for restoring a system to its previous state if issues arise after a change. This practice minimizes downtime and ensures continuity of operations.

Other options may address risk or project management but do not specifically ensure a way to revert changes if they do not go as planned.

Virtual Network Computing (VNC) is the correct answer because it is a graphical desktop-sharing system that uses the Remote Frame Buffer (RFB) protocol to remotely control another computer. It's platform-independent, meaning it can work across different operating systems, making it versatile for cross-platform support.

RDP (Remote Desktop Protocol) is specific to Windows systems and isn't platform-independent. SSH (Secure Shell) is primarily for command-line access and doesn't provide graphical interface control by default. FTP (File Transfer Protocol) is used for transferring files, not for remote desktop control.

Disabling AutoRun is a security best practice that prevents the operating system from automatically executing commands found in the autorun.inf file on removable media. This directly mitigates the risk of malware launching automatically when a device like a USB flash drive is inserted. While other options are valid security measures, they do not address the specific threat of automatic execution from removable media. A screen lock protects against unauthorized physical access, full-disk encryption protects data at rest, and a BIOS/UEFI password secures the pre-boot environment.

To manage security settings and software installation for users and computers - This is correct. Group Policy is a feature in Windows that allows administrators to centrally manage and configure operating system settings, security configurations, software installations, and user environment settings for both users and computers in an Active Directory domain.

To control user access to internet downloads - While Group Policy can be used to manage internet-related settings, its scope is much broader and includes managing a variety of system and user configurations beyond internet downloads.

To configure hardware settings for workstations only - Group Policy is not limited to hardware settings or workstations. It can configure settings for both users and computers across an entire domain, including policies related to software, security, and more.

To enforce password policies for individual user accounts - While Group Policy can enforce password policies, it does so at a domain or organizational level, not for individual user accounts. Managing individual accounts is handled through other tools like Local Users and Groups or Active Directory Users and Computers.

Degaussing is the process of erasing data from magnetic storage devices by using a powerful magnetic field. This process makes the data on the storage medium unrecoverable, meeting high security standards. Standard formatting and erasing do not completely eliminate data, and low-level formatting (while effective) is more complex and less practical compared to degaussing.

Storing network equipment in a locked wiring closet or server room restricts physical access to authorized personnel only, reducing the risk of tampering, theft, or accidental damage. Placing devices in open or highly visible locations makes unauthorized access easier and therefore weakens security.

The answer is a rootkit. A rootkit allows a hacker to gain privileged access to a target’s computer while being extremely difficult to detect. The other choices are other types of malware that do not allow for control of the infected computer.

The principle of least privilege ensures that users have only the permissions they need to complete their tasks, reducing the risk of accidental or intentional misuse of resources.

Other options involve more general access controls, which do not focus on minimizing permissions.

copy - This is correct. The copy command is used to duplicate files from one location to another in a Windows environment. It creates a copy of the file at the destination while keeping the original file intact.

move - The move command relocates files from one location to another. Unlike copy, it does not leave the original file in the source location.

dir - The dir command lists files and directories in the current or specified folder. It does not duplicate or move files.

mkdir - The mkdir command (short for "make directory") is used to create a new directory. It does not handle file duplication.

Grounding the equipment is the most effective way to protect sensitive electronic components from electrostatic discharge (ESD). Using a properly grounded ESD mat provides a path for static electricity to flow safely to ground instead of discharging through the electronic components.

The two most common ways to inject pop-up windows into a web browsing session is by using a malicious application which will most likely be found by the anti-virus software, or by installing a plugin or extension to the browser that creates the pop-ups. Some free applications downloadable from the internet will install these plugins as a way to create ad revenue.

The correct command for displaying IP configuration details, including the subnet mask and default gateway, is 'ipconfig'. This command provides essential network information for troubleshooting and configuration.

The other options, while related to networking, do not provide the specific details required for this task. For instance, 'ping' tests connectivity to another device but doesn't display IP settings, and 'netstat' shows active connections, which is unrelated to retrieving IP configuration.

The most important tool in preventing malware is user education. Users are the weakest and least controllable link in the security chain. A majority of malware is introduced into a network from the actions of a user.
