A user calls the help desk to report that mapped drives are no longer accessible. The technician verifies that clicking on any of the drives on the user's machine results in an error message. Other users in the office are not having any issues. As a first step, the technician would like to remove and attempt to reconnect the drives. Which of the following command-line tools should the technician use?
A. net use
B. set
C. mkdir
D. rename
Correct Answer: A
The technician should use net use command-line tool to remove and reconnect mapped drives. Net use is a command that allows users to manage network connections and resources, such as shared folders or printers. Net use can be used to map or unmap network drives by specifying their drive letters and network paths. For example, net use Z: \server\share maps drive Z: to \server\share folder, and net use Z: /delete unmaps drive Z:. Set is a command that displays or modifies environment variables for the current user or process. Set is not related to managing mapped drives. Mkdir is a command that creates a new directory or folder in the current or specified location. Mkdir is not related to managing mapped drives. Rename is a command that renames a file or folder in the current or specified location. Rename is not related to managing mapped drives.

Question 202:
Which of the following features allows a technician to configure policies in a Windows 10 Professional desktop?
A. gpedit
B. gpmc
C. gpresult
D. gpupdate
Correct Answer: A
The feature that allows a technician to configure policies in a Windows 10 Professional desktop is gpedit. Gpedit is a command that opens the Local Group Policy Editor, which is a utility that allows users to view and modify local group policies on their Windows PC. Local group policies are a set of rules and settings that control the behavior and configuration of the system and its users. Local group policies can be used to configure policies such as security, network, software installation and user rights. Gpmc is a command that opens the Group Policy Management Console, which is a utility that allows users to view and modify domain-based group policies on a Windows Server. Domain-based group policies are a set of rules and settings that control the behavior and configuration of the computers and users in a domain. Domain-based group policies are not available on a Windows 10 Professional desktop. Gpresult is a command that displays the result of applying group policies on a Windows PC. Gpresult can be used to troubleshoot or verify group policy settings but not to configure them. Gpupdate is a command that updates or refreshes the group policy settings on a Windows PC. Gpupdate can be used to apply new or changed group policy settings but not to configure them. References: CompTIA A+ Core 2 (220-1002) Certification Exam Objectives Version 4.0, Domain 1.6
Question 203:
A user updates a mobile device's OS. A frequently used application becomes consistently unresponsive immediately after the device is launched. Which of the following troubleshooting steps should the user perform FIRST?
A. Delete the application's cache.
B. Check for application updates.
C. Roll back the OS update.
D. Uninstall and reinstall the application.
Correct Answer: B
Checking for application updates is the first troubleshooting step that the user should perform, because the application may not be compatible with the new OS version and may need an update to fix the issue. Deleting the application's cache,
rolling back the OS update, or uninstalling and reinstalling the application are possible solutions, but they are more time-consuming and disruptive than checking for updates.

A. Rolling back video card drivers
B. Restoring the PC to factory settings
C. Repairing the Windows profile
D. Reinstalling the Windows OS
Correct Answer: A
Rolling back video card drivers is the best way to resolve the issue of large desktop icons on a user's newly issued PC. This means restoring the previous version of the drivers that were working fine before the software patch was deployed. The software patch may have caused compatibility issues or corrupted the drivers, resulting in display problems
Question 205:

crypt32.d11 is missing not found
Which of the following should the technician attempt FIRST?
A. Rebuild Windows profiles.
B. Reimage the workstation
C. Roll back updates
D. Perform a system file check
Correct Answer: D
If this file is missing or corrupted, it can cause application crashes or errors when trying to open websites in a browser. To fix this, the technician can perform a system file check, which is a utility that scans and repairs corrupted or missing system files. To perform a system file check, the technician can follow these steps: Open the Command Prompt as an administrator. To do this, type cmd in the search box on the taskbar, right-click on Command Prompt, and select Run as administrator. In the Command Prompt window, type sfc /scannow and hit Enter. This will start the scanning and repairing process, which may take some time. Wait for the process to complete. If any problems are found and fixed, you will see a message saying Windows Resource Protection found corrupt files and successfully repaired them. If no problems are found, you will see a message saying Windows Resource Protection did not find any integrity violations. Restart your computer and check if the issue is resolved.
Question 206:
A user is trying to use a third-party USB adapter but is experiencing connection issues. Which of the following tools should the technician use to resolve this issue?
A. taskschd.msc
B. eventvwr.msc
C. de vmgmt. msc
D. diskmgmt.msc
Correct Answer: C
The tool that the technician should use to resolve the connection issues with the third-party USB adapter is devmgmt.msc. Devmgmt.msc is a command that opens the Device Manager, which is a utility that allows users to view and manage the hardware devices and drivers installed on a computer. The technician can use the Device Manager to check the status, properties and compatibility of the USB adapter and its driver, and perform actions such as updating, uninstalling or reinstalling the driver, enabling or disabling the device, or scanning for hardware changes. Taskschd.msc is a command that opens the Task Scheduler, which is a utility that allows users to create and manage tasks that run automatically at specified times or events. The Task Scheduler is not relevant or useful for resolving connection issues with the USB adapter. Eventvwr.msc is a command that opens the Event Viewer, which is a utility that allows users to view and monitor the system logs and events. The Event Viewer may provide some information or clues about the connection issues with the USB adapter, but it does not allow users to manage or troubleshoot the device or its driver directly. Diskmgmt.msc is a command that opens the Disk Management, which is a utility that allows users to view and manage the disk drives and partitions on a computer. The Disk Management is not relevant or useful for resolving connection issues with the USB adapter. References: CompTIA A+ Core 2 (220-1002) Certification Exam Objectives Version 4.0, Domain 1.6
Question 207:
A user has been unable to receive emails or browse the internet from a smartphone while traveling. However, text messages and phone calls are working without issue. Which of the following should a support technician check FIRST?
A. User account status
B. Mobile OS version
C. Data plan coverage
D. Network traffic outages
Correct Answer: C
The first thing that a support technician should check to resolve the issue of not being able to receive emails or browse the internet from a smartphone while traveling is the data plan coverage. The data plan coverage determines how much data and where the user can use on the smartphone's cellular network. The data plan coverage may vary depending on the user's location, carrier and subscription. The data plan coverage may not include or support certain areas or countries that the user is traveling to, or may charge extra fees or limit the speed or amount of data that the user can use. The data plan coverage does not affect text messages and phone calls, which use different network services and protocols. User account status is not likely to cause the issue of not being able to receive emails or browse the internet from a smartphone while traveling, unless the user account has been suspended or terminated by the carrier or the email provider. Mobile OS version is not likely to cause the issue of not being able to receive emails or browse the internet from a smartphone while traveling, unless the mobile OS has a major bug or compatibility problem with the network or the email app. Network traffic outages may cause the issue of not being able to receive emails or browse the internet from a smartphone while traveling, but they are less likely and less common than data plan coverage issues, and they should also affect text messages and phone calls.

Question 208:
A user updates a mobile device's OS. A frequently used application becomes consistently unresponsive immediately after the device is launched. Which of the following troubleshooting steps should the user perform FIRST?
A. Delete the application's cache.
B. Check for application updates.
C. Roll back the OS update.
D. Uninstall and reinstall the application.
Correct Answer: B
Sometimes, an OS update can cause compatibility issues with some applications that are not optimized for the new version of the OS. To fix this, the user should check if there are any updates available for the application that can resolve the
issue. The user can check for application updates by following these steps:
On an Android device, open the Google Play Store app and tap on the menu icon in the top left corner. Then tap on My apps and games and look for any updates available for the application. If there is an update, tap on Update to install it. On
an iOS device, open the App Store app and tap on the Updates tab at the bottom. Then look for any updates available for the application. If there is an update, tap on Update to install it.
Question 209:
A user is unable to log in to the network. The network uses 802.1X with EAP-TLS to authenticate on the wired network. The user has been on an extended leave and has not logged in to the computer in several months. Which of the following is causing the login issue?
A. Expired certificate
B. OS update failure
C. Service not started
D. Application crash
E. Profile rebuild needed
Correct Answer: A
EAP-TLS is a method of authentication that uses certificates to establish a secure tunnel between the client and the server. The certificates have a validity period and must be renewed before they expire. If the user has been on an extended leave and has not logged in to the computer in several months, it is possible that the certificate on the client or the server has expired and needs to be renewed. The other options are not directly related to EAP-TLS authentication or 802.1X network access.
Question 210:
A new employee was hired recently. Which of the following documents will the new employee need to sign before being granted login access to the network?
A. MSDS
B. EULA
C. UAC
D. AUP
Correct Answer: D
A new employee will need to sign an AUP before being granted login access to the network. An AUP is an Acceptable Use Policy that defines the rules and guidelines for using network resources and services in an organization. An AUP typically covers topics such as security, privacy, ethics, compliance and liability issues related to network usage. An AUP helps protect the organization and its users from legal, regulatory and reputational risks associated with network activities. An MSDS is a Material Safety Data Sheet that provides information about hazardous substances and how to handle them safely. An MSDS is not related to network access or usage. A EULA is an End User License Agreement that specifies the terms and conditions for using a software product or service. A EULA is usually provided by software vendors or developers and does not apply to network access or usage in general. A UAC is a User Account Control that is a security feature that prompts users for permission or confirmation before performing certain actions that require elevated privileges or affect system settings. A UAC is not a document that needs to be signed by users but a mechanism that helps prevent unauthorized changes or malware infections on a system.
