Update and Security is the section in Windows 10 Settings that allows the user to back up their device. Backing up a device means creating a copy of the data and settings on the device and storing it in another location, such as an external drive or a cloud service. Backing up a device can help the user restore their data and settings in case of data loss, corruption, or theft. Devices and Printers, Email and Accounts, and Apps and Features are not sections in Windows 10 Settings that allow the user to back up their device.

AutoPlay is a feature that automatically runs programs or files when a removable media device, such as a flash drive, is plugged in. This can be exploited by malware authors who place malicious files on flash drives that execute automatically when inserted into a computer. Turning off AutoPlay can prevent this type of incident by requiring the user to manually open or run files from removable media devices. Disabling UAC (user account control), restricting local administrators and enabling UPnP (universal plug and play) are not effective ways to prevent this type of incident.

A corporate use license, also known as a volume license, is a type of software license that allows an organization to purchase and use multiple copies of a software product with a single license key. A corporate use license can help validate compliance with an application’s EULA (end-user license agreement), which is a legal contract that defines the terms and conditions of using the software. A corporate use license can also reduce the number of licenses to manage, as it eliminates the need to activate and track individual licenses for each copy of the software. Personal use license, open-source license, and non-expiring license are not types of licenses that can best accomplish this goal.

 The best way to address the security and privacy concerns caused by a malware infection on a smartphone is to uninstall all recently installed applications and schedule an antivirus scan. Uninstalling the applications that may have introduced the malware can help remove the source of infection and prevent further damage. Scheduling an antivirus scan can help detect and remove any remaining traces of malware and restore the device’s functionality.

Group Policy is a feature of Windows that allows administrators to centrally manage and apply policies and settings to computers and users on a domain3. Group Policy can be used to configure network drives, printers, security settings, desktop preferences, and other configurations for all users’ workstations3. Network and Sharing Center, net use, User Accounts, and regedit are not tools that can accomplish this task.

OSX (now macOS) is an operating system that is considered closed source, meaning that its source code is not publicly available or modifiable by anyone except its developers. It is owned and maintained by Apple Inc. Ubuntu, Android and CentOS are operating systems that are considered open source, meaning that their source code is publicly available and modifiable by anyone who wants to contribute or customize them.

The correct answer is A. Document the date and time of change. After implementing a change, the technician should document the date and time of change in the change log or record. This helps to track the change history, monitor the change performance, and identify any issues or incidents related to the change. Documenting the date and time of change is also a good practice for auditing and compliance purposes.

Documenting the purpose of the change (B) and the risk level © are steps that should be done before implementing the change, not after. These are important information that help to justify, prioritize, and plan the change. The purpose of the change should explain why the change is needed and what benefits it will bring to the organization. The risk level should assess the potential impact and probability of the change causing any problems or disruptions to the business.

Documenting the findings of the sandbox test (D) is also a step that should be done before implementing the change, not after. A sandbox test is a way of testing the change in an isolated environment that mimics the production environment. This helps to verify that the change works as expected and does not cause any errors or conflicts with other systems or processes. The findings of the sandbox test should be documented and reviewed by the change advisory board (CAB) before approving the change for implementation.

Zombies and botnets are terms that describe the types of infections that can cause internal workstations to participate in a DDoS (distributed denial-of-service) attack. A DDoS attack is a malicious attempt to disrupt the normal functioning of a website or a network by overwhelming it with a large amount of traffic from multiple sources. Zombies are infected computers that are remotely controlled by hackers without the owners’ knowledge or consent. Botnets are networks of zombies that are coordinated by hackers to launch DDoS attacks or other malicious activities. Keylogger, adware, ransomware, and spyware are not types of infections that can cause internal workstations to participate in a DDoS attack.

Quarantining the computer means isolating it from the network and other devices to prevent the spread of malware or ransomware. Ransomware is a type of malware that encrypts the files on a computer and demands payment (usually in cryptocurrency) to restore them. If a technician sees a file that is requesting payment to a cryptocurrency address, it is likely that the computer has been infected by ransomware. Quarantining the computer should be the first step to contain the infection and prevent further damage. Disabling System Restore, updating the antivirus software definitions, and booting to safe mode are not steps that should be done before quarantining the computer.

The correct answer is A. Amount of system RAM. A Type 2 hypervisor is a virtualization software that runs on top of a host operating system, which means it shares the system resources with the host OS and other applications. Therefore, increasing the amount of system RAM can improve the performance of the hypervisor and the virtual machines running on it. RAM is used to store data and instructions that are frequently accessed by the CPU, and having more RAM can reduce the need for swapping data to and from the storage device, which is slower than RAM.

NIC performance, storage IOPS, and dedicated GPU are not as relevant for improving the hypervisor’s performance in this scenario. NIC performance refers to the speed and quality of the network interface card, which is used to connect the computer to a network. Storage IOPS refers to the number of input/output operations per second that can be performed by the storage device, which is a measure of its speed and efficiency. Dedicated GPU refers to a separate graphics processing unit that can handle complex graphics tasks, such as gaming or video editing. These components may affect other aspects of the computer’s performance, but they are not directly related to the hypervisor’s ability to compile new source code.

Network drives can be automatically mapped for users based on Group Policy configuration using log-in scripts. Here’s how it works:

Log-in scripts: These are scripts executed when a user logs in to a domain. They can be configured through Group Policy in Active Directory to map network drives automatically. The scripts can use commands like net use to map drives.

Access control lists (ACLs): While ACLs control permissions for files and folders, they do not automatically map network drives.

Organizational units (OUs): OUs are used to organize users and computers in a directory structure but do not map drives.

Folder redirection: This redirects the path of a folder to a new location, typically on a network share, but it does not automatically map drives.

The user should configure extensions/add-ins. Since the issue involves a browser plug-in, checking if the extension or add-in is enabled or properly configured can resolve the issue. If the plug-in is disabled, the OTP prompt will not appear as expected.

When a customer experiences display issues such as large icons and inaccurate colors after a Windows upgrade, the most appropriate Control Panel option to address these issues is "Device Manager." The technician can use Device Manager to check and update display drivers, which are often the cause of such problems after an OS upgrade. Updating or reinstalling the correct drivers can help resolve display resolution and color issues.

A. Ease of Access focuses on accessibility features and does not directly address display driver issues.

C. Network and Sharing Center is related to network settings and does not affect display settings.

D. Programs and Features is used for managing installed programs and features but is not relevant for updating display drivers.

In this case, abnormal behavior after opening a suspicious email suggests malware might have infected the device. A full factory reset is recommended to remove any persistent malware, especially when a restart does not resolve the issue. Deleting the email or reinstalling the browser will not remove the malware already on the device.
