A virtual private network (VPN) is a technology that creates a secure and encrypted connection over a public network, such as the internet. A VPN allows remote employees to access the corporate intranet as if they were physically connected to the local network3. Password-protected Wi-Fi is a security measure for wireless networks that does not provide access to the corporate intranet. Port forwarding is a technique that allows external devices to access services on a private network through a router, but does not provide access to the corporate intranet. A perimeter network is a network segment that lies between an internal network and an external network, such as the internet, and provides an additional layer of security, but does not provide access to the corporate intranet.

 The user can most likely make the change of extending the display to a second monitor in the System option in the Windows settings. The System option allows users to manage system settings and features, such as display, sound, notifications, power and storage. The user can extend the display to a second monitor by selecting Display from the System option and then choosing Extend these displays from the Multiple displays drop-down menu. This will allow the user to use both monitors as one large desktop area. Devices is an option in the Windows settings that allows users to add and manage devices connected to the computer, such as printers, scanners, mice and keyboards. Devices is not related to extending the display to a second monitor but to configuring device settings and preferences. Personalization is an option in the Windows settings that allows users to customize the appearance and behavior of their desktop, such as themes, colors, backgrounds, lock screen and screensaver. 

Time Machine is the built-in backup feature for macOS that allows users to back up their system automatically. It continuously backs up everything on the Mac, including files, applications, system files, and settings, allowing users to restore their system to a previous state if needed. Time Machine operates by creating hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months. Other options like "Mission Control" help in organizing windows, while "System Restore" is a feature more common in Windows operating systems, not macOS.

After implementing a change authorized by the change advisory board (CAB), the technician should document the date and time of change as part of the post-implementation review. This helps to track the change history, verify the success of the change, and identify any issues or incidents caused by the change1. Documenting the purpose of the change, the risk level, and the findings of the sandbox test are all part of the pre-implementation activities that should be done before submitting the change request to the CAB2.

Windows 10 Enterprise is an edition of Windows 10 that is designed for large organizations that need advanced security and management features. Windows 10 Enterprise can be activated using different methods, such as Multiple Activation Key (MAK), Active Directory-based Activation (ADBA), or Key Management Service (KMS)1. KMS is a method of activation that uses a local server to activate multiple devices on a network. KMS activations are valid for 180 days and need to be renewed periodically by connecting to the KMS server2. If a device does not renew its activation within 180 days, it will enter a grace period of 30 days, after which it will display a warning message and lose some functionality until it is reactivated3. The other editions of Windows 10 do not require reactivation every 180 days. Windows 10 Pro for Workstation is an edition of Windows 10 that is designed for high-performance devices that need advanced features such as ReFS file system, persistent memory, and faster file sharing. Windows 10 Pro for Workstation can be activated using a digital license or a product key. Windows 10 Home is an edition of Windows 10 that is designed for personal or home use. Windows 10 Home can be activated using a digital license or a product key. Windows 10 Pro is an edition of Windows 10 that is designed for business or professional use. Windows 10 Pro can be activated using a digital license or a product key. None of these editions require reactivation every 180 days unless there are significant hardware changes or other issues that affect the activation status.

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

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

A possible cause of the user being redirected to unexpected websites is that the localhost file entries have been modified by malware or hackers to point to malicious or unwanted websites. The localhost file is a text file that maps hostnames to IP addresses and can override DNS settings. By examining the localhost file entries, a technician can identify and remove any suspicious or unauthorized entries that may cause the redirection issue. Enabling firewall ACLs may not resolve the issue if the firewall rules do not block the malicious or unwanted websites. Verifying the routing tables may not resolve the issue if the routing configuration is correct and does not affect the web traffic. Updating the antivirus definitions may help prevent future infections but may not remove the existing malware or changes to the localhost file.

A network technician installed a SOHO router for a home office user. The user has read reports about home routers being targeted by malicious actors and then used in DDoS attacks. Which of the following can the technician MOST likely do to defend against this threat?

A. Add network content filtering.

B. Disable the SSID broadcast.

C. Configure port forwarding.

D. Change the default credentials.

Answer: D

 One of the most effective ways to defend against malicious actors targeting home routers for DDoS attacks is to change the default credentials of the router. The default credentials are often well-known or easily guessed by attackers, who can then access and compromise the router settings and firmware. By changing the default credentials to strong and unique ones, a technician can prevent unauthorized access and configuration changes to the router. Adding network content filtering may help block some malicious or unwanted websites but may not prevent attackers from exploiting router vulnerabilities or backdoors. Disabling the SSID broadcast may help reduce the visibility of the wireless network but may not prevent attackers from scanning or detecting it. Configuring port forwarding may help direct incoming traffic to specific devices or services but may not prevent attackers from sending malicious packets or requests to the router.
