AUP (Acceptable Use Policy) should be updated to reflect this new requirement. The AUP is a document that outlines the acceptable use of technology within an organization. It is a set of rules that employees must follow when using company resources. The AUP should be updated to include a policy on cryptocurrency mining on work desktops

The smartphone’s line was not provisioned with a data plan. The user is unable to use any internet-related functions on the smartphone when it is not connected to Wi-Fi because the smartphone’s line was not provisioned with a data plan. The user can send and receive text messages and phone calls when the smartphone is not connected to Wi-Fi because these functions do not require an internet connection1

The technician should configure the network as private to allow the user to access files on a drive shared from another desktop on the network1

The technician should update the browser’s CRLs first. The error message indicates that the certificate revocation list (CRL) is not up to date. Updating the CRLs will ensure that the browser can verify the authenticity of the bank’s website.

Multifactor authentication will be forced for Wi-Fi after deploying a client certificate to be used for Wi-Fi access for all devices in an organization3

The correct answer is D. Services. The print spooler is a service that manages the print queue and sends print jobs to the printer. To restart the print spooler, the salesperson can use the Services app, which allows them to stop and start the service. Alternatively, they can also use the Task Manager or the Command Prompt to restart the print spooler.

References and Explanation:

The Services app is a tool that displays all the services that are running on the computer. It can be accessed by typing services.msc in the Run window or by searching for Services in the Start menu. The Services app allows users to start, stop, restart, or configure any service, including the print spooler123.

The Task Manager is a tool that shows information about the processes, applications, and services that are running on the computer. It can be accessed by pressing Ctrl + Shift + Esc or by right-clicking on the taskbar and selecting Task Manager. The Task Manager allows users to start, stop, or restart any service by going to the Services tab and right-clicking on the service name12.

The Command Prompt is a tool that allows users to execute commands and perform tasks using text input. It can be accessed by typing cmd in the Run window or by searching for Command Prompt in the Start menu. The Command Prompt allows users to start, stop, or restart any service by using the net command with the service name. For example, to restart the print spooler, users can type net stop spooler and then net start spooler1.

The Control Panel is a tool that provides access to various settings and options for the computer. It can be accessed by typing control panel in the Run window or by searching for Control Panel in the Start menu. The Control Panel does not allow users to restart the print spooler directly, but it can be used to access other tools such as Devices and Printers, Troubleshooting, or Administrative Tools2.

The Processes tab is a part of the Task Manager that shows information about the processes that are running on the computer. It can be accessed by opening the Task Manager and selecting the Processes tab. The Processes tab does not allow users to restart the print spooler directly, but it can be used to end any process that is related to printing or causing problems with the print spooler2.

The Startup tab is a part of the Task Manager that shows information about the programs that run automatically when the computer starts. It can be accessed by opening the Task Manager and selecting the Startup tab. The Startup tab does not allow users to restart the print spooler directly, but it can be used to disable or enable any program that affects printing or interferes with the print spooler2.

Sandbox testing is a method of identifying potential issues with a proposed change prior to implementation. It involves creating a simulated or isolated environment that mimics the real system and applying the change to it. This can help to verify that the change works as expected and does not cause any errors or conflicts. Request form, rollback plan and end-user acceptance are other components of a change management process, but they do not involve identifying issues with a change.

Disk Defragment is a tool that can be used to improve the performance of a hard disk drive (HDD). HDDs store data in sectors and clusters on spinning platters. Over time, as data is written, deleted, and moved, the data may become fragmented, meaning that it is spread across different locations on the disk. This causes the HDD to take longer to access and load data, resulting in slower performance. Disk Defragment consolidates the fragmented data and rearranges it in a contiguous manner, which reduces the seek time and increases the speed of the HDD. Disk Management, Disk Cleanup, and Device Manager are not tools that can alleviate the issue of slow HDD performance.

ACL (access control list) is a security control that describes what permissions a user or group has on a shared network folder using NTFS (New Technology File System) security settings. It can be used to grant or deny read, write, modify, delete or execute access to files and folders. SMS (short message service), MFA (multifactor authentication), MDM (mobile device management) are not security controls that apply to shared network folders.

Uninstalling and reinstalling the application can resolve the issue of it crashing immediately on an Android tablet, as it can fix any corrupted or missing files or settings. Clearing the application storage can also resolve the issue, as it can free up space and remove any conflicting data. Gaining root access to the tablet, resetting the web browser cache, deleting the application cache and disabling mobile device management are not likely to resolve the issue, as they do not affect how the application runs.

An AUP, or Acceptable Use Policy, is a set of rules applied by the owner, creator, or administrator of a network, website, or service that restricts the ways in which the network, website, or system may be used. In this scenario, the administrator is likely referring to the company's AUP, which outlines what employees can and cannot do on the company's network, including restrictions on accessing certain types of websites, such as sports teams' sites, for non-work-related purposes.

AUP (Acceptable Use Policy): This policy typically includes rules designed to maintain the security of the network, ensure the productivity of employees, and comply with legal regulations. Blocking access to specific websites is a common practice enforced through an AUP to align with these goals.

An NDA (Non-Disclosure Agreement) (A) is a legal contract between at least two parties that outlines confidential material, knowledge, or information that the parties wish to share with one another for certain purposes but wish to restrict access to or by third parties. A VPN (Virtual Private Network) (C) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. SOP (Standard Operating Procedures) (D) are a set of step-by-step instructions compiled by an organization to help workers carry out complex routine operations, which wouldn't typically include website access guidelines.

The correct answer is C. Choose what closing the lid does. This option allows you to configure how the laptop behaves when you close the lid, such as whether it goes to sleep, hibernates, shuts down, or does nothing. To access this option, you can follow these steps :

Go to Settings > System > Power & sleep.

Click on Additional power settings on the right side.

Click on Choose what closing the lid does on the left side.

Under When I close the lid, select Do nothing for both On battery and Plugged in.

Click on Save changes.

This will prevent the laptop from going to sleep when you close the lid while it is connected to the docking station and the external monitor.

Hibernate, sleep/suspend, and turn on fast startup are not the options that should be configured to fix the issue. Hibernate and sleep/suspend are both power-saving modes that allow you to resume your work without losing any data. However, they also turn off the display and other components of the laptop, which means you will not be able to use the external monitor when the laptop is closed. Turn on fast startup is a feature that reduces the boot time of Windows by saving some system information to a file when you shut down. It does not affect how the laptop behaves when you close the lid .

When upgraded computers are not able to obtain an IP address, the issue often lies in the network configuration. Here’s a

Option A: The switch is only providing IPv6 addresses.This is unlikely because if the switch were providing IPv6 addresses, the devices would still receive an IP address, albeit an IPv6 one. The issue described indicates no IP address is being obtained at all.

Option B: The OS must be updated to be compatible with the imaging software.This option is unrelated to obtaining an IP address. Compatibility with imaging software would not prevent the devices from getting an IP address.

Option C: The switch has port security enabled.Correct Answer. Port security on a switch restricts access based on MAC addresses. If the MAC addresses of the upgraded computers are not recognized or have not been added to the allowed list, the switch will not provide network access, resulting in the computers not obtaining an IP address.

WPA2/AES (Wi-Fi Protected Access 2/Advanced Encryption Standard) is a wireless security standard that supports enterprise mode, which allows a user to use login credentials (username and password) to authenticate to available corporate SSIDs (service set identifiers). TACACS+ (Terminal Access Controller Access-Control System Plus) and Kerberos are network authentication protocols, but they are not wireless security features. Preshared key is another wireless security feature, but it does not use login credentials.

Calibrating the phone sensors is a step that can troubleshoot the issue of screen not autorotating on a mobile device. Screen autorotation is a feature that automatically adjusts the screen orientation based on the device’s position and movement. Screen autorotation relies on sensors such as accelerometer and gyroscope to detect the device’s tilt and rotation. Calibrating the phone sensors can help fix any errors or inaccuracies in the sensor readings that may prevent screen autorotation from working properly. Enabling the touch screen, reinstalling the operating system, and replacing the screen are not steps that should be done next to troubleshoot this issue.

A graphics card, also known as a video card or a GPU (graphics processing unit), is a component that can affect the performance of a computer game. A graphics card is responsible for rendering and displaying graphics on the screen, such as images, animations, and effects. A computer game may require a high level of graphics processing power to run smoothly and achieve high frame rates, which are the number of frames per second (FPS) that the game can display. Upgrading to a better graphics card can improve the performance of a computer game by increasing its graphics quality and frame rates. Hard drive, random-access memory, and monitor are not components that can directly improve the performance of a computer game.

The correct answer is D. Unattended installation. An unattended installation is a way of installing Windows 10 without requiring any user input or interaction. It uses a configuration file called answer file that contains the settings and preferences for the installation, such as the product key, language, partition, and network settings. An unattended installation can be performed by using a bootable USB flash drive or DVD that contains the Windows 10 installation files and the answer file1. This is the fastest way for the technician to install Windows 10 on a newly built computer, as it automates the whole process and saves time.

A factory reset is a way of restoring a computer to its original state by deleting all the data and applications and reinstalling the operating system. A factory reset can be performed by using the recovery partition or media that came with the computer, or by using the Reset this PC option in Windows 10 settings2. A factory reset is not a way of installing Windows 10 on a newly built computer, as it requires an existing operating system to be present.

A system restore is a way of undoing changes to a computer’s system files and settings by using a restore point that was created earlier. A system restore can be performed by using the System Restore option in Windows 10 settings or by using the Advanced Startup Options menu3. A system restore is not a way of installing Windows 10 on a newly built computer, as it requires an existing operating system and restore points to be present.

An in-place upgrade is a way of upgrading an existing operating system to a newer version without losing any data or applications. An in-place upgrade can be performed by using the Windows 10 Media Creation Tool or by running the Setup.exe file from the Windows 10 installation media. An in-place upgrade is not a way of installing Windows 10 on a newly built computer, as it requires an existing operating system to be present.

The correct answer is D. Force Quit. Force Quit is a macOS feature that allows users to close an application that has stopped responding. To use Force Quit, users can press and hold Option (or Alt), Command, and Esc (Escape) keys together, or choose Force Quit from the Apple menu in the corner of the screen. A Force Quit window will open, where users can select the application that they want to close and click Force Quit123.
