Risk analysis is the process of identifying and evaluating the potential threats and impacts of a change on the system, network, or service. It is an essential step before approving a change request, as it helps to determine the level of risk, the mitigation strategies, and the contingency plans. Risk analysis also helps to prioritize the change requests based on their urgency and importance12.

The scope of the change is one of the elements that should be documented to ensure that the change management plan is followed. The scope of the change defines the boundaries and limitations of the change, such as what is included and excluded, what are the deliverables and outcomes, what are the assumptions and constraints, and what are the dependencies and risks. The scope of the change helps to clarify the expectations and objectives of the change, as well as to prevent scope creep or deviation from the original plan. The scope of the change also helps to measure the progress and success of the change, as well as to communicate the change to the stakeholders and the team

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.

PowerShell is a scripting language that can interact with Active Directory and other Windows components. It has a built-in cmdlet called New-ADUser that can create user accounts in Active Directory. PowerShell can also use the Active Directory module to access other AD-related functions and attributes. Other languages, such as Bash, SQL, and PHP, are not designed for creating Active Directory accounts and would require additional tools or libraries to do so.

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.

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.

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 msconfig.exe tool, also known as the System Configuration utility, is a tool that allows users to modify various system settings, such as startup options, services, boot options, and more. One of the features of msconfig.exe is the ability to disable or enable device drivers that are loaded during the system startup. By using msconfig.exe, a technician can prevent a driver from being loaded and used by the system, which will allow them to uninstall it without any errors. To use msconfig.exe to disable a driver, the technician can follow these steps:

Open the Run dialog box by pressing the Windows key + R.

Type msconfig.exe and press Enter.

Click on the Boot tab and then click on Advanced options.

Check the box next to No GUI boot and click OK. This will prevent the graphical user interface from loading during the boot process, which will also prevent some drivers from loading.

Click on the Services tab and check the box next to Hide all Microsoft services. This will show only the third-party services and drivers that are running on the system.

Find the service or driver that corresponds to the device that the technician wants to uninstall and uncheck the box next to it. This will disable the service or driver from starting during the system startup.

Click Apply and OK and then restart the computer.

After the computer restarts, the technician can use the Device Manager or the Control Panel to uninstall the driver that was previously in use.

Remote network installation is the best option for configuring a new server that requires a bare-metal installation without installation media on site. A remote network installation is a method of installing an operating system or an application over a network connection, such as LAN, WAN, or Internet. A remote network installation can use various protocols, such as PXE, HTTP, FTP, or SMB, to access the installation files from a server or a cloud service. A remote network installation can also use various tools, such as Windows Deployment Services, Microsoft Deployment Toolkit, or Red Hat Kickstart, to automate and customize the installation process. A remote network installation can save time and resources by eliminating the need for physical media and allowing centralized management of multiple installations. Image deployment, recovery partition installation, and repair installation are not correct answers for this question. Image deployment is a method of installing an operating system or an application by copying a preconfigured image file to a target device. Image deployment requires an existing image file and a compatible device. Recovery partition installation is a method of restoring an operating system or an application from a hidden partition on the hard disk that contains the original factory settings. Recovery partition installation requires an existing recovery partition and a functional hard disk. Repair installation is a method of fixing an operating system or an application that is corrupted or damaged by replacing or repairing the system files without affecting the user data or settings. Repair installation requires an existing operating system or application and a working device. References:

Reinstalling the application is the best option to fix the intermittent crashing of the application on the corporate smartphone. Reinstalling the application will ensure that the latest version of the app is installed, which may have bug fixes and compatibility updates that can resolve the crashing issue. Reinstalling the app will also clear any corrupted or outdated data or cache that may cause the app to malfunction.

The other options are not as effective or appropriate as reinstalling the app. Restarting the phone may temporarily fix the issue, but it will not address the root cause of the app crashing, which may be related to the app itself or its data. Reimaging the OS is a drastic and unnecessary measure that will erase all the data and settings on the phone and restore it to its factory state. This will also remove all the other apps and files that may be important for the corporate use of the phone. Clearing the cache may help to free up some space and improve the performance of the app, but it will not update the app or fix any bugs that may cause the app to crash.

Recovery mode is a special boot option that allows the user to access advanced tools and features to troubleshoot and remove malware from the device. Recovery mode can also restore the system to a previous state or reset the device to factory settings. Running System Restore, scheduling a scan, or restarting the PC may not be effective in removing the malware, as it may still be active or hidden in the system files.

Isolating the machine from the network is a good practice when troubleshooting a PC that is suspected of being infected with malware. This can prevent the malware from spreading to other devices on the network or communicating with external servers that may control or exploit the malware. Isolating the machine can be done by disconnecting the network cable, disabling the wireless adapter, or blocking the network traffic with a firewall.

The Network and Sharing Center is a Control Panel utility that allows users to view and modify network settings, such as IP address, subnet mask, default gateway, DNS servers, and network profiles. To change the IP and gateway settings of a Windows workstation, the technician can follow these steps:

Open the Network and Sharing Center by clicking on the network icon in the system tray or by searching for it in the Start menu.

Click on Change adapter settings on the left sidebar.

Right-click on the network adapter that is connected to the network and select Properties.

Double-click on Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) depending on the network protocol used.

Select Use the following IP address and enter the desired IP address, subnet mask, and default gateway for the workstation. Alternatively, select Obtain an IP address automatically if the network uses DHCP to assign IP addresses dynamically.

Click OK to save the changes and close the dialog boxes.

The first mitigation step that a technician should take when a machine is suspected to contain ransomware is to quarantine the system. This means isolating the infected machine from the network and other devices, to prevent the ransomware from spreading and encrypting more data. The technician can quarantine the system by disconnecting the network cable, turning off the wireless adapter, or using firewall rules to block the traffic from and to the machine12.

This step is more important than the other options because:

Disabling System Restore (A) is not a priority, as it will not stop the ransomware from running or spreading. System Restore is a feature that allows users to restore their system to a previous state, but it may not work if the ransomware has encrypted or deleted the restore points. Moreover, disabling System Restore may prevent the user from recovering some data or settings in the future13.

Remediating the system (B) is the ultimate goal, but it cannot be done before quarantining the system. Remediating the system means removing the ransomware, restoring the data, and fixing the vulnerabilities that allowed the attack. However, this process requires careful analysis, planning, and execution, and it may not be possible if the ransomware is still active and communicating with the attackers. Therefore, the technician should first isolate the system and then proceed with the remediation steps12.

Educating the system user © is a preventive measure, but it is not a mitigation step. Educating the system user means raising awareness and providing training on how to avoid ransomware attacks, such as by recognizing phishing emails, avoiding suspicious links or attachments, and updating and patching the system regularly. However, this step will not help if the system is already infected, and it may not be effective if the user is not willing or able to follow the best practices. Therefore, the technician should focus on resolving the current incident and then educate the user as part of the recovery plan14.

app files are application bundles that contain all the necessary files and resources for a Mac app. They can be easily deleted by dragging them to the Trash or using Launchpad12. Other file types, such as .exe, .dmg, .rpm, and .pkg, are either not compatible with macOS or require additional steps to uninstall34.
