Remotely wiping the device is the best option to prevent unauthorized access to the company data stored on the phone. A low-level format, degaussing, or providing the GPS location of the device are not feasible or effective actions to take in this scenario.

WPA2 is the only protocol among the options that supports fast roaming between networks.Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), enables a client device to roam quickly in environments implementing WPA2 Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another1. WEP, WPA, LEAP, and PEAP do not support fast roaming and require the client device to perform the full authentication process every time it roams, which can cause delays and interruptions in the network service.

BitLocker is a Windows security feature that provides encryption for entire volumes, addressing the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned devices1.BitLocker helps mitigate unauthorized data access by enhancing file and system protections, rendering data inaccessible when BitLocker-protected devices are decommissioned or recycled1. Network share, Group Policy, and Static IP are not features that can prevent unauthorized data access if a computer is lost or stolen.

devmgmt.msc is the MMC snap-in that opens the Device Manager, a tool that allows the technician to view and manage the hardware devices and their drivers on the computer1. If the applications are not updating properly, it could be due to outdated, corrupted, or incompatible drivers that prevent the hardware from functioning normally.The technician can use the Device Manager to update, uninstall, rollback, or disable the drivers, as well as scan for hardware changes, troubleshoot problems, and view device properties2.

gpedit.msc is the MMC snap-in that opens the Group Policy Editor, a tool that allows the technician to configure the local or domain group policy settings for the computer or a group of computers3. Group policy settings can affect the security, performance, and functionality of the system, but they are not directly related to the application updates or the hardware drivers.

perfmon.msc is the MMC snap-in that opens the Performance Monitor, a tool that allows the technician to monitor and analyze the performance of the system and its components, such as processor, memory, disk, network, etc4.Performance Monitor can display real-time data or collect log data for later analysis, as well as generate reports and alerts based on the performance counters5. Performance Monitor can help the technician identify and diagnose performance issues, but it does not provide a way to manage the hardware drivers.

The Network & Internet settings in Windows 10 allow the user to input the SSID and password of a Wi-Fi network, as well as manage other network-related options, such as airplane mode, mobile hotspot, VPN, proxy, etc1.To access the Network & Internet settings, the user can select the Start button, then select Settings > Network & Internet2.Alternatively, the user can right-click the Wi-Fi icon on the taskbar and click 'Open Network & Internet Settings'3.

The System settings in Windows 10 allow the user to configure the display, sound, notifications, power, storage, and other system-related options1.The Personalization settings in Windows 10 allow the user to customize the background, colors, lock screen, themes, fonts, and other appearance-related options1.The Accounts settings in Windows 10 allow the user to manage the user accounts, sign-in options, sync settings, and other account-related options1. None of these settings can be used to input the SSID and password of a Wi-Fi network.

MFA stands for multi-factor authentication, which is an electronic authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN1. MFA provides security enhancement by making it harder for attackers to compromise the user's identity or credentials, as they would need to obtain more than just the username and password.MFA can also prevent unauthorized access to sensitive data or resources, as well as reduce the risk of identity theft or fraud2.

Installing new software on an organization's system or device can have various implications, such as compatibility, security, performance, licensing, and compliance issues.Therefore, it is important to follow the best practices for software installation, such as doing research on the software, checking the system requirements, scanning the installation file for malware, and obtaining the proper license345. The technician should not install the software without formal approval from the management team, as this could violate the organization's policies or regulations. The technician should also not install the software without investigating the software and its impact on the organization, as this could introduce potential risks or problems to the system or device.The technician should indicate to the developer that formal approval is needed, and then work with the IT team to evaluate the software and its suitability for the organization before installing it

Loading the system in safe mode is a common troubleshooting step that allows the technician to isolate the problem by disabling unnecessary drivers and services. This can help determine if the issue is caused by a faulty device, a corrupted system file, or a malware infection.

The most likely causes of the user's Windows computer performance degradation and freezing are insufficient RAM and excessive software running in the background. Therefore, the technician should do the following to resolve the issue:

Increase the RAM. RAM is the memory that the computer uses to store and run applications and processes. If the RAM is not enough to handle the workload, the computer will use the hard drive as a virtual memory, which is much slower and can cause performance issues. Increasing the RAM will allow the computer to run more applications and processes smoothly and avoid freezing. The technician should check the system requirements of the applications that the user needs to run, and install additional RAM modules that are compatible with the motherboard and the existing RAM.The technician should also make sure that the system is managing the page file size automatically, or adjust it manually to optimize the virtual memory usage12.

Uninstall unnecessary software. Software that the user does not need or use can take up valuable disk space and system resources, and can interfere with the performance of other applications. Some software may also run in the background or start automatically when the computer boots up, which can slow down the system and cause freezing. The technician should help the user to identify and uninstall unnecessary software from the control panel or the settings app, and disable unnecessary startup programs from the task manager or the system configuration tool.The technician should also check for and remove viruses and malware that may affect the system performance134.
