CompTIA CompTIA A+ Certification Core 2 Exam 220-1102 Exam Dumps: Updated Questions & Answers (July 2026)

Detailed Explanation with Core 2 References:SSH allows for remote access to systems securely and discretely, suitable for verifying patch levels and other administrative tasks. This meets Core 2 objectives on using secure remote access tools (Core 2 Objective 4.9)​.

A recovery key is a code that can be used to unlock a BitLocker-encrypted drive when the normal authentication methods (such as password or PIN) are not available or have been forgotten. BitLocker is a feature of Windows that encrypts the entire drive to protect data from unauthorized access. If a technician is trying to repair a Windows 10 OS that has BitLocker enabled, they will need the recovery key to access the drive and continue the OS repair. SSL key, preshared key, and WPA2 key are not keys that are related to BitLocker or OS repair.

 The best action to protect against unauthorized access of the data on the lost company tablet is to perform a remote wipe on the device. A remote wipe is a feature that allows an administrator or a user to erase all the data and settings on a device remotely, usually through a web portal or an email command. A remote wipe can help prevent the data from being accessed or compromised by anyone who finds or steals the device. Changing the office’s Wi-Fi SSID and password may prevent the device from connecting to the office network but may not prevent the data from being accessed locally or through other networks. Changing the user’s password may prevent the device from logging in to the user’s account but may not prevent the data from being accessed by other means or accounts. Enabling remote drive encryption may protect the data from being read by unauthorized parties but may not be possible if the device is already lost or turned off.

A S.M.A.R.T. error is a warning that a hard drive is about to fail or has failed. This means that the OS cannot be loaded from the drive and the user will see an error message indicating there is no OS found. The most likely cause of this issue is drive failure.

The most likely reason that the system is not utilizing all the available RAM is that it is running a 32-bit OS. A 32-bit OS can only address up to 4GB of RAM, and some of that is reserved for hardware and system use1. Therefore, even if the technician installed 8GB of RAM, the system can only use around 3.5GB of usable RAM. To use the full 8GB of RAM, the technician would need to install a 64-bit OS, which can address much more memory2. The system missing updates, the system’s memory failing, or the system requiring BIOS updates are not likely to cause this issue.

DHCP stands for Dynamic Host Configuration Protocol and it is used to assign IP addresses and other network configuration parameters to devices on a network automatically. This is useful for devices that do not require the same private address each time they connect to the internet. 

The best sign-on option that would allow any employee the ability to unlock the kiosk that relies exclusively on a numeric keypad is to use a PIN and provide it to employees. A PIN is a Personal Identification Number that is a numeric code that can be used as part of authentication or access control. A PIN can be entered using only a numeric keypad and can be easily shared with employees who need to unlock the kiosk. Requiring employees to enter their usernames and passwords may not be feasible or convenient if the kiosk only has a numeric keypad and no other input devices. Setting up facial recognition for each employee may not be possible or secure if the kiosk does not have a camera or biometric sensor. Requiring employees to use their fingerprints may not be possible or secure if the kiosk does not have a fingerprint scanner or biometric sensor.

SMB stands for Server Message Block, which is a network file sharing protocol that allows applications on a computer to read and write to files and to request services from server programs in a computer network. SMB is a built-in protocol in Windows operating systems and can be used to transfer files between computers over a network. The technician can use SMB to access a file share on the user’s workstation and copy the file to or from it. VPN stands for virtual private network, which is a technology that creates a secure and encrypted connection over a public network. VPN is not a built-in protocol in Windows operating systems and does not directly transfer files between computers. RMM stands for remote monitoring and management, which is a type of software solution that allows remote management and monitoring of devices and networks. RMM is not a built-in protocol in Windows operating systems and does not directly transfer files between computers. MSRA stands for Microsoft Remote Assistance, which is a feature that allows a user to invite another user to view or control their computer remotely. MSRA is not a protocol, but an application that uses Remote Desktop Protocol (RDP) to establish a connection. MSRA does not directly transfer files between computers.

When a user rotates a cell phone horizontally to read emails and the display remains vertical, even though the settings indicate autorotate is on, this is typically due to a problem with the phone's accelerometer. The accelerometer is the sensor that detects changes in the phone's orientation and adjusts the display accordingly. If the accelerometer is not calibrated correctly, the display may not rotate as expected.

Recalibrating the accelerometer is the most likely solution to this issue. The process for recalibrating the accelerometer can vary depending on the specific device and operating system, but it typically involves going to the device's settings and finding the option to calibrate or reset the sensor. Users may need to search their device's documentation or online resources to find specific instructions for their device.

The error message “Your connection is not private. Authority invalid.” means that the web browser cannot verify the identity or security of the website’s SSL certificate. This could indicate that the website has been compromised, has a configuration error, or has an expired or invalid certificate. The user should not proceed to the site or use a different browser, as this could expose their sensitive information to potential attackers. The user should also not reinstall the browser, as this is unlikely to fix the error and could cause data loss. The best action for the user to take is to report the error to the bank and wait for them to resolve it.

 The most likely reason that the system is not utilizing all the available RAM is that the system is utilizing a 32-bit OS. A 32-bit OS is an operating system that uses 32 bits to address memory locations and perform calculations. A 32-bit OS can only support up to 4GB of RAM, and some of that RAM may be reserved for hardware devices or system functions, leaving less than 4GB of usable RAM for applications and processes. A 32-bit OS cannot recognize or utilize more than 4GB of RAM, even if more RAM is installed on the system. To utilize all the available RAM, the system needs to use a 64-bit OS, which can support much more RAM than a 32-bit OS. The system missing updates may cause some performance or compatibility issues, but it does not affect the amount of usable RAM on the system. The system’s memory failing may cause some errors or crashes, but it does not affect the amount of usable RAM on the system. The system requiring BIOS updates may cause some configuration or compatibility issues, but it does not affect the amount of usable RAM on the system.

The hostname command-line tool is used to display the name of the local machine. This information can be crucial for identifying the device within a network, especially when setting up remote access or sharing resources like folders and printers. Unlike other command-line tools that provide more detailed network diagnostics or configuration details, hostname straightforwardly offers the device's network identification, making it suitable for the scenario described.References: Official CompTIA A+ Core 1 and Core 2 Student Guide​​.

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.

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.

To troubleshoot a user's computer remotely while the user is connected, the best option is Microsoft Remote Assistance (MSRA). MSRA allows the technician to view and control the user's screen with their permission, facilitating an effective troubleshooting session without disconnecting the user.

The new laptop was set up with the static IP it needs to connect to the software. The old desktop is still configured with that IP, hence the conflict.

Over time, especially with frequent opening, modification, and saving of large files, a hard disk drive (HDD) can become fragmented. Fragmentation occurs when pieces of individual files are scattered across the disk, leading to longer read and write times, which can significantly slow down the computer. Disk defragmentation reorganizes these fragmented files, placing the pieces closer together on the drive, which improves access time and overall system performance.

Disk Defragment: Using the Disk Defragment tool on a Windows 10 system with an HDD will help in reorganizing the data more efficiently, thus potentially remedying the slow performance issue.

The Registry Editor (B) is a tool that allows for the viewing and editing of the Windows registry and is generally not used for performance improvement but rather for system settings and configuration adjustments. System Information (C) provides a detailed look at the computer's hardware and system details but does not offer tools for performance improvement. Disk Cleanup (D) can help free up space on the hard drive by removing temporary files and system files that are no longer needed, which can indirectly improve performance but is not the primary tool for addressing fragmentation.

Scripting languages are designed for automating tasks by writing scripts that can execute a series of commands. They are typically easier to write and understand compared to compiled languages and are widely used for automating repetitive tasks, making them the best option for task automation.

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.

Explanation:

Reinstalling the browser would most likely solve the issue. This would remove any malicious software or add-ons that may be causing the issue and restore the browser to its default settings.
