220-1102 CompTIA A+ Certification Core 2 Exam Free Practice Exam Questions (2025 Updated)

When an Android device starts exhibiting issues like frequent crashes and rapid battery drain after downloading an application, the first step should be to address the immediate cause:

Uninstall the game application: Since the issues started after the game application was installed, removing it is a logical first step. Unwanted or malicious applications can cause such symptoms by running harmful processes in the background or exploiting system resources.

Install the latest security patches: Keeping the device updated with the latest security patches is crucial for protecting against vulnerabilities that could be exploited by malicious software. Updating can resolve existing security flaws and improve device stability.

For a company with geographically dispersed staff and the need to keep devices updated, using cloud-based endpoint management software is the most efficient method. This type of software allows IT administrators to remotely manage and push updates to company devices, regardless of their location. It ensures that all devices remain up to date with the latest security patches and software updates without requiring physical access or user intervention. This approach is scalable, reduces the risk of unpatched vulnerabilities, and is convenient for both the IT department and the end-users.

Before starting a bare-metal installation of Windows 10, ensuring that there is sufficient storage space on the system's hard drive or SSD is crucial. This is because the installation files need enough room to be copied and for the operating system to be installed and function properly. Without adequate storage, the installation process can fail or the operating system might not perform optimally. Other prerequisites like internet connection, product key, and specific firmware types might be necessary at different stages of installation or activation, but the fundamental requirement is enough storage space to accommodate the new OS.

When an email is encrypted and the recipient cannot open it, the issue typically revolves around the need for encryption keys. Encryption keys are used to encode and decode the email content, ensuring that only authorized recipients with the correct key can access the information. In this scenario, the user would need to receive the appropriate decryption key from the sender to unlock and read the encrypted email. This exchange ensures that sensitive information remains secure during transmission and is only accessible to intended recipients.

For scripting the creation of Active Directory accounts, PowerShell (D) is used. PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and the associated scripting language. It is built on the .NET framework and is particularly suited for automating and managing Windows-based systems, including Active Directory tasks​​.

A rollback plan describes the process of reverting a system to its previous state after a failed upgrade or change. This ensures system stability and functionality by restoring known good configurations and is a crucial part of change management to minimize disruptions in case of unsuccessful updates.

Restarting the smartphone can resolve a wide range of technical issues, including those related to Bluetooth connectivity. This simple step can refresh the system and eliminate temporary software glitches that might be interfering with Bluetooth functions like audio output and data synchronization.

Restart the smartphone: This action clears the system's RAM and can resolve conflicts between the Bluetooth service and other processes running on the smartphone, potentially fixing both the audio and synchronization issues.

Resetting network settings (B) could also potentially fix the issue but is a more drastic step that also clears Wi-Fi networks and passwords, cellular settings, and VPN configurations, which might not be necessary. Unpairing the Bluetooth speaker (C) could help if the issue is specific to the speaker, but since there are also synchronization issues with the smartwatch, the problem seems broader. Checking for system updates (D) is a good general maintenance step, but it's more likely to help with ongoing or known issues rather than immediate connectivity problems.

A system image is a complete snapshot of everything on a device's storage at a given point in time, including the operating system, installed programs, system settings, and all user files. This method is the best way to back up the OS and data comprehensively because it allows for the restoration of a system to its exact state at the time the image was taken. This is particularly useful in disaster recovery scenarios where it's crucial to restore a system quickly and efficiently to minimize downtime.

An AUP, or Acceptable Use Policy, is a set of rules applied by the owner, creator, or administrator of a network, website, or service that restricts the ways in which the network, website, or system may be used. In this scenario, the administrator is likely referring to the company's AUP, which outlines what employees can and cannot do on the company's network, including restrictions on accessing certain types of websites, such as sports teams' sites, for non-work-related purposes.

AUP (Acceptable Use Policy): This policy typically includes rules designed to maintain the security of the network, ensure the productivity of employees, and comply with legal regulations. Blocking access to specific websites is a common practice enforced through an AUP to align with these goals.

An NDA (Non-Disclosure Agreement) (A) is a legal contract between at least two parties that outlines confidential material, knowledge, or information that the parties wish to share with one another for certain purposes but wish to restrict access to or by third parties. A VPN (Virtual Private Network) (C) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. SOP (Standard Operating Procedures) (D) are a set of step-by-step instructions compiled by an organization to help workers carry out complex routine operations, which wouldn't typically include website access guidelines.

If a technician is unable to run an OS installation file and receives a message indicating no software is installed to handle the file, the next step is to mount the ISO file. Mounting the ISO will create a virtual drive from which the installation can be run, mimicking the behavior of a physical installation media.

When handling a user support request that contains insufficient information, the first step a technician should take is to Ask the user for clarification (A). This involves gathering more details about the issue to understand the problem better and provide an accurate resolution. Effective communication and asking the right questions are essential for diagnosing and resolving IT issues efficiently​​.

The most likely reason for an error message stating "Not compatible with OS" during a software installation is that the installation requires administrative rights. Many software installations, especially those that affect system files or install drivers, require administrative privileges to execute correctly. Without these rights, the installer cannot make the necessary changes to the system, leading to such error messages​​.

Authenticator applications are designed to enhance security by generating temporary, time-sensitive passcodes used in two-factor authentication (2FA) processes. These passcodes are used in conjunction with traditional credentials (like usernames and passwords) to grant access to systems or applications. This extra layer of security ensures that even if primary login credentials are compromised, unauthorized access is still prevented without the dynamically generated code from the authenticator app.

For securely disposing of SSDs, physical destruction methods like shredding are considered most effective:

Shredding: This method involves physically breaking the SSD into small pieces, making data recovery practically impossible. It's a recommended practice for ensuring that sensitive data on SSDs is irretrievably destroyed.

Booting in safe mode is the initial step to diagnose a computer experiencing a blue screen of death (BSOD) following a failed Windows 10 update. Safe mode starts the computer with a minimal set of drivers and services, allowing troubleshooting and identification of the problematic software or driver causing the BSOD. This mode provides a safer environment to uninstall recent updates or drivers, perform system scans, and restore the system if necessary. Other options like System Restore wizard, last known-good configuration, and resetting BIOS settings may be subsequent steps but do not directly diagnose the issue as effectively as booting in safe mode.

To secure a SOHO wireless network, enabling WPA3 is the recommended option. WPA3 (Wi-Fi Protected Access 3) is the latest security certification program developed by the Wi-Fi Alliance to secure wireless computer networks. It provides cutting-edge security protocols and cryptographic methods to enhance and replace its predecessors, WPA2 and WPA, offering improved protection against brute-force attacks and ensuring better privacy on public networks​​.

The Network and Sharing Center in the Control Panel is the central place to manage network connections and settings in Windows. When facing issues with accessing a mapped drive, this utility allows users to review and adjust network settings, making it possible to resolve connectivity problems. It provides options to view network status, set up new connections, change adapter settings, and troubleshoot network problems, which can help in enabling connectivity to the mapped drive on the Windows XP machine.

Using a password manager is the best way to mitigate the issue of users recording their login information in accessible areas. Password managers securely store and encrypt passwords and login details, reducing the need for users to write down or remember multiple complex passwords. This approach enhances security by encouraging the use of strong, unique passwords for different accounts without the risk of forgetting them or the unsafe practice of writing them down. Trusted sources, valid certificates, and user training are important security measures but do not directly address the problem of managing multiple secure passwords as effectively as a password manager does.

The correct tool to use for removing upgrade files and freeing up disk space on a Windows desktop is cleanmgr.exe, which stands for Disk Cleanup. Disk Cleanup is a maintenance utility included in Microsoft Windows designed to free up disk space on a computer's hard drive. The utility scans and analyzes the hard drive for files that are no longer of any use, and then removes the unnecessary files. It can delete temporary files, system files, empty the Recycle Bin, and remove a variety of system files and other items that you might no longer need​​.

Improving password security is crucial to protect user accounts from unauthorized access. Requiring passwords to include four character types—uppercase letters, lowercase letters, numbers, and special characters—significantly enhances password complexity. This diversity in characters makes passwords much harder to guess or crack using common methods like brute force attacks, thereby improving overall security.

Requiring four character types: This approach forces users to create more complex and less predictable passwords, reducing the risk of simple passwords that are easy to exploit.

Decreasing the password expiration times (B) can encourage users to change their passwords more frequently but does not directly address the issue of password complexity. Enabling an automatic lock timer (C) can add a layer of security by locking accounts after a period of inactivity, but it does not improve the strength of the passwords themselves. Adding two characters to the minimum password length (D) can help to some extent by making passwords longer, but without requiring a mix of character types, passwords might still remain relatively easy to guess or crack.

On macOS, uninstalling an application typically involves locating the app in Finder and dragging it to the Trash. This method is straightforward and commonly used for removing unwanted applications. The other options do not directly relate to the standard process of uninstalling applications on a Mac.

The presence of pop-up windows advertising free software and the error message about memory are indicative of spyware infection. Installing and running antispyware software is a practical first step to remove the unwanted software and resolve the issue without resorting to more drastic measures like re-imaging the system.

When an Android device experiences slow boot times and application crashes after installing apps from a third-party website, scanning the system for malware is a critical first step. Third-party sources can often host malicious software that can compromise device performance and security. A malware scan can identify and remove such threats, potentially resolving the performance issues and application instability. Clearing the web browser cache, enrolling the device in an MDM system, and confirming app compatibility are useful steps but do not address the immediate concern of potential malware introduced by third-party app installations.

To enforce a security policy that prohibits USB drives on user workstations, the network administrator should run the gpupdate (C) command. This command forces a Group Policy update, which can include policies to disable USB drives. Group Policy is a feature in Microsoft Windows that allows for centralized management and configuration of operating systems, applications, and users' settings in an Active Directory environment​​.

The 'top' command in Linux is used to display the running processes along with information about system resources like CPU and memory usage. It provides a real-time view of the system's resource consumption, making it an essential tool for monitoring and managing system performance.

The account access level the user will need to access advanced features and configuration settings for several applications while adhering to corporate policy requiring a least privilege environment is a standard account. This is because a standard account allows the user to access advanced features and configuration settings for several applications while adhering to corporate policy requiring a least privilege environment1.

When encountering a warning about antivirus protection malfunctioning, the first step should be to isolate the computer from the network to prevent potential spread of malware. Updating the endpoint protection software is also crucial to ensure the latest virus definitions and security features are in place to effectively identify and remove the threat.

Shredding is the most effective method to securely dispose of data stored on optical discs12

 This is because a PIN is a fast and secure method of logging in to laptops, and it is more secure than a password because it is not susceptible to keyloggers.
