 An evil twin is a type of social-engineering attack that involves setting up a rogue wireless access point that mimics a legitimate one. The attacker can then intercept or modify the traffic of the users who connect to the fake SSID. The attacker may also use phishing or malware to steal credentials or personal information from the users

The technician should adjust the firewall settings to resolve the issue of not being able to access an internal site at https://companyintranet.com:8888. The firewall settings control how the firewall filters and allows network traffic based on rules and policies. The firewall settings may be blocking or preventing the access to the internal site by mistake or by default, especially if the site uses a non-standard port number such as 8888. The technician should check and modify the firewall settings to allow the access to the internal site or its port number. Default gateway settings determine how a computer connects to other networks or the internet. Default gateway settings are not likely to cause the issue of not being able to access an internal site if the user can access the public internet. DHCP settings determine how a computer obtains its IP address and other network configuration parameters automatically from a DHCP server. DHCP settings are not likely to cause the issue of not being able to access an internal site if the user can access other network resources. IP address settings determine how a computer identifies itself and communicates with other devices on a network. IP address settings are not likely to cause the issue of not being able to access an internal site if the user can access other network resources. Antivirus settings control how the antivirus software scans and protects the computer from malware and threats. Antivirus settings are less likely to cause the issue of not being able to access an internal site than firewall settings, unless the antivirus software has its own firewall feature that may interfere with the network traffic.

The piece of hardware that the technician should replace to resolve the issue of the screen failing to rotate on a mobile device that was dropped is the accelerometer. The accelerometer is a sensor that detects the orientation and movement of the mobile device by measuring the acceleration forces acting on it. The accelerometer allows the screen to rotate automatically according to the position and angle of the device. If the accelerometer is damaged or malfunctioning, the screen may not rotate properly or at all, even if the settings are correctly applied. LCD stands for Liquid Crystal Display and is a type of display that uses liquid crystals and backlight to produce images on the screen. LCD is not related to the screen rotation feature but to the quality and brightness of the display. Battery is a component that provides power to the mobile device by storing and releasing electrical energy. Battery is not related to the screen rotation feature but to the battery life and performance of the device. Digitizer is a component that converts touch inputs into digital signals that can be processed by the mobile device. Digitizer is not related to the screen rotation feature but to the touch sensitivity and accuracy of the display.

 The user is experiencing a vishing attack. Vishing stands for voice phishing and is a type of social-engineering attack that uses phone calls or voice messages to trick users into revealing personal or financial information. Vishing attackers often pretend to be from legitimate organizations, such as banks, government agencies or service providers, and use various tactics, such as urgency, fear or reward, to persuade users to comply with their requests. Phishing is a type of social-engineering attack that uses fraudulent emails or websites to trick users into revealing personal or financial information. Phishing does not involve phone calls or voice messages. Smishing is a type of social-engineering attack that uses text messages or SMS to trick users into revealing personal or financial information. Smishing does not involve phone calls or voice messages. Whaling is a type of social-engineering attack that targets high-profile individuals, such as executives, celebrities or politicians, to trick them into revealing personal or financial information. Whaling does not necessarily involve phone calls or voice messages. References: CompTIA A+ Core 2 (220-1002) Certification Exam Objectives Version 4.0, Domain 3.1

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

When troubleshooting boot times for a user, a technician may want to check which programs are starting with the operating system to identify any that may be slowing down the boot process. MSConfig is a tool that can be used to view startup items on a Windows system, but it may not always be available or functional.

In this scenario, the technician receives a message that MSConfig cannot be used to view startup items. As an alternative, the technician can use Task Manager (taskmgr), which can also display the programs that run at startup. To access the list of startup items in Task Manager, the technician can follow these steps:

Open Task Manager by pressing Ctrl+Shift+Esc.

Click the "Startup" tab.

The list of programs that run at startup will be displayed.

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.

The tool that the technician will most likely use to remotely connect to a Linux desktop is VNC. VNC stands for Virtual Network Computing and is a protocol that allows remote access and control of a graphical desktop environment over a network. VNC is natively designed for Linux and can also support other operating systems, such as Windows and Mac OS. VNC can be used to assist users with troubleshooting by viewing and interacting with their desktops remotely. MFA stands for Multi-Factor Authentication and is a method of verifying identity using two or more factors, such as something you know, something you have or something you are. MFA is not a tool that can be used to remotely connect to a Linux desktop but a technique that can be used to enhance security for systems or services. MSRA stands for Microsoft Remote Assistance and is a feature that allows remote access and control of a Windows desktop environment over a network. MSRA is not natively designed for Linux and may not be compatible or supported by Linux systems. RDP stands for Remote Desktop Protocol and is a protocol that allows remote access and control of a Windows desktop environment over a network. RDP is not natively designed for Linux and may not be compatible or supported by Linux systems. References: CompTIA A+ Core 2 (220-1002) Certification Exam Objectives Version 4.0, Domain 1.6

Content filtering is a process that manages or screens access to specific emails or webpages based on their content categories1. Content filtering can be used by organizations to control content access through their firewalls and enforce corporate policies around information system management2. A SOHO client may have content filtering enabled on their network and may need to adjust it to allow access to a corporate website that is blocked by default. The client can use a software program, a hardware device, or a subscription service to configure the content filtering settings and whitelist the desired website2.

Shredding is the best method to use for the physical destruction of SSDs because it reduces them to small pieces that cannot be recovered or accessed. Wiping, low-level formatting, and erasing are not effective methods for destroying SSDs because they do not physically damage the flash memory chips that store data1.

The user can change the wallpaper using a Windows 10 Settings tool by following these steps12:

Open Settings by pressing the Windows key and typing Settings, or by clicking the gear icon in the Start menu.

Select Personalization from the left navigation menu.

On the right side of the window, click Background.

In the Background settings, click the drop-down menu and select Picture as the background type.

Click Browse and then locate and open the image the user wants to use as the wallpaper.

The other options are incorrect because they do not lead to the Background settings or they do not allow the user to browse for an image. Accounts, System, and Apps are not related to personalization settings. Your info, Display, and Apps & features are not related to wallpaper settings.

Robocopy is a command-line utility that can be used to mirror the source data for the backup. It can copy files and folders with various options, such as copying only changed files, preserving attributes and permissions, and retrying failed copies. Robocopy is more powerful and flexible than copy or xcopy, which are simpler commands that can only copy files and folders without mirroring or other advanced features. Copy-Item is a PowerShell cmdlet that can also copy files and folders, but it is not a native Windows utility and it requires PowerShell to run1.

The software is most likely to install by default in the /Applications directory, which is the standard location for macOS applications. This directory can be accessed from the Finder sidebar or by choosing Go > Applications from the menu bar. The /Applications directory contains all the applications that are available to all users on the system1. Some applications might also offer the option to install in the ~/Applications directory, which is a personal applications folder for a single user2. The /etc/services directory is a system configuration file that maps service names to port numbers and protocols3. The /usr/bin directory is a system directory that contains executable binaries for various commands and utilities4. The C:\Program Files directory is a Windows directory that does not exist on macOS.

Keychain is a feature of macOS that securely stores passwords, account numbers, and other confidential information for your Mac, apps, servers, and websites1. You can use the Keychain Access app on your Mac to view and manage your keychains and the items stored in them1. Keychain can also sync your passwords and other secure information across your devices using iCloud Keychain1. Keychain can be used as a password manager in macOS to help you keep track of and protect your passwords.

 Mission Control is the macOS feature that provides the user with a high-level view of all open windows. Mission Control allows the user to see and switch between multiple desktops, full-screen apps, and windows in a single screen. Mission Control can be accessed by swiping up with three or four fingers on the trackpad, pressing F3 on the keyboard, or moving the cursor to a hot corner

 Chain of custody and data integrity are two options that should most likely be considered when preserving data from a hard drive for forensic analysis. Chain of custody refers to the documentation and tracking of who has access to the data and how it is handled, stored, and transferred. Data integrity refers to the assurance that the data has not been altered, corrupted, or tampered with during the preservation process

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.

Drilling and incinerating are physical destruction methods that make the data on hard drives unrecoverable. Standard formatting, erasing and low-level formatting are logical methods that can be reversed with data recovery tools. Recycling is not a destruction method at all.

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.
