When configured properly, Remote Desktop uses encrypted connections to protect data transmitted between the client and the host computer. This feature is particularly useful for IT support, remote work, or managing multiple computers from a central location. It allows users to control the desktop environment, access files, run applications, and perform administrative tasks as if they were physically present at the machine. Proper configuration of user accounts, network settings, and firewall rules ensures secure remote connections and prevents unauthorized access.
File History is designed to back up user files on a regular schedule. While important for data protection, it does not provide any functionality for remote system access. File History only helps restore previous versions of files and cannot be used to control or monitor the computer remotely. Using File History in this context would not achieve the goal of enabling secure remote connections, making it irrelevant to this scenario.
Task Scheduler allows automated execution of scripts, applications, or maintenance tasks at predefined times. Although it can automate certain functions, Task Scheduler does not provide live access to the system or allow a user to control the desktop remotely. It is useful for automation and system maintenance, but it is not a solution for enabling remote access to a computer.
Device Manager is a utility for managing hardware devices and their drivers. It allows technicians to troubleshoot hardware issues, update drivers, and verify device functionality. While essential for hardware maintenance, Device Manager cannot enable remote desktop connections or provide secure remote access.
The reasoning for selecting Remote Desktop is that it directly addresses the need for controlled, secure, remote connectivity. Unlike backup tools, task automation utilities, or hardware management utilities, Remote Desktop provides real-time access to the system while supporting encryption and user authentication. This ensures that remote access is functional, secure, and efficient, allowing administrators or users to perform tasks without physically being present at the computer. By configuring Remote Desktop properly, the technician can ensure both security and functionality, making it the most appropriate solution for enabling remote system access.

A) AppLocker
B) Windows Firewall
C) Disk Cleanup
D) Device Manager
Answer: A) AppLocker
Explanation:
AppLocker is a Windows feature that allows administrators to control which applications and executable files users can run on a system. By creating rules that specify allowed or blocked applications based on file path, publisher, or hash, AppLocker ensures that only authorized software can execute. This prevents unauthorized installations, reduces the risk of malware infections, and enforces compliance with organizational policies. AppLocker is especially valuable in enterprise environments, where controlling software usage is critical for security and productivity. It integrates with Group Policy, allowing centralized management of application permissions across multiple systems.
Windows Firewall monitors and controls network traffic, preventing unauthorized access to the system from external sources. While it enhances security, the firewall does not control which applications can be installed or run locally. Its function is network protection, not software execution control, making it inadequate for restricting unauthorized installations.
Disk Cleanup is a utility that frees up storage by removing temporary files, system caches, and other unnecessary data. Although it improves performance and storage management, Disk Cleanup does not provide any functionality to control software installation or prevent users from executing unauthorized applications. Its purpose is maintenance, not access control.
Device Manager allows technicians to view, manage, and troubleshoot hardware devices. While it ensures that devices and drivers function correctly, it does not provide any control over software installation or execution. Device Manager is strictly focused on hardware, making it irrelevant for the purpose of preventing unauthorized applications.
The reasoning for selecting AppLocker is that it provides precise, enforceable control over software execution. Unlike firewalls or maintenance tools, AppLocker directly addresses the need to prevent unauthorized installations, which reduces security risks and ensures compliance. By configuring AppLocker rules, the technician can control applications based on trust, publisher, or system location, providing a scalable and effective method for enforcing organizational policies.

The «IRQL_NOT_LESS_OR_EQUAL» blue screen error typically indicates a problem with system drivers or hardware interrupt requests. Outdated or incompatible drivers can cause conflicts with system processes, leading to critical system errors and crashes. Checking for driver updates is the first troubleshooting step because it directly targets the most common cause of this type of blue screen. Updating drivers ensures that hardware components are compatible with the operating system and that any known bugs or conflicts are resolved. This approach is non-invasive, can prevent further system crashes, and addresses the problem at its source without unnecessary reinstallation of software.
Clearing temporary files is a maintenance task that removes unnecessary data from the system. While helpful for freeing disk space or improving performance, it does not affect hardware drivers, system interrupts, or kernel-level operations. Temporary files are unrelated to IRQL errors and would not resolve the blue screen issue.
Adjusting screen resolution changes how the display renders content but has no impact on system drivers or interrupt handling. Display settings affect visual output but do not influence kernel-level processes or hardware conflicts that trigger a blue screen. Changing the resolution will not prevent or fix IRQL-related crashes.
Reinstalling Microsoft Office addresses productivity software issues but does not resolve system-level driver conflicts or hardware interrupt problems. The office is unrelated to kernel operations, interrupt requests, or driver functionality. Performing a reinstall would be time-consuming and ineffective as a solution for blue screen errors caused by driver issues.
The reasoning for checking driver updates first is that it directly addresses the primary cause of the IRQL_NOT_LESS_OR_EQUAL error. By updating drivers, the technician ensures that hardware components and system software communicate correctly, resolving conflicts that lead to system crashes.

Question 34
A user wants to protect their Windows device from ransomware attacks. Which of the following actions provides the most effective protection?
A) Regularly back up important files to an external drive
B) Increase virtual memory
C) Disable Windows Update
D) Uninstall Microsoft Office
Answer: A) Regularly back up important files to an external drive
Explanation:
Ransomware encrypts files on a computer and demands payment to restore access. Regularly backing up important files to an external drive ensures that data remains safe even if the system is compromised. Backups allow users to restore files without paying ransom or losing critical information. External drives or cloud storage solutions that are not continuously connected to the system provide additional protection because ransomware cannot access them once disconnected. This proactive measure addresses the consequences of ransomware rather than attempting to prevent the infection, providing a reliable recovery method that minimizes data loss and business impact.
Increasing virtual memory affects system performance by allowing the operating system to use disk space as supplemental RAM. While this can improve responsiveness, it does not protect against ransomware infections or prevent the encryption of files. Virtual memory is unrelated to security and is ineffective as a mitigation strategy.
Disabling Windows Update is counterproductive for ransomware protection. Updates often include security patches that fix vulnerabilities exploited by ransomware. Turning off updates leaves the system exposed to known exploits, increasing the likelihood of infection. Therefore, this action reduces security rather than providing protection.
Uninstalling Microsoft Office removes productivity tools but does not inherently prevent ransomware. While some malware targets Office files, ransomware attacks typically affect all user files on the system, not just Office documents. Removing Office does not address the threat or provide recovery options, making it ineffective as a protection measure.
The reasoning for backing up important files is that it provides a reliable way to recover from ransomware attacks. While other measures, such as antivirus software, firewalls, and security updates, are important, having offline backups ensures that critical data is not lost even if the system is compromised. Backups combined with security best practices create a comprehensive protection strategy that addresses both prevention and recovery, making it the most effective method to mitigate the impact of ransomware.

Explanation:
When a USB external hard drive is not detected, the first troubleshooting step should be to check the physical connection, including the USB cable and port. A faulty cable or port is a common cause of connectivity issues and can prevent the system from recognizing the device. Testing the cable on another port or using a known working cable can quickly determine whether the problem is hardware-related. Ensuring that the connection is secure and functional allows the technician to eliminate simple physical issues before exploring software or driver-related causes.
Defragmenting the hard drive is a maintenance process that reorganizes fragmented data on a storage device. While it improves access performance, it does not affect whether a USB device is detected by the system. Defragmentation is irrelevant to connectivity problems and does not resolve recognition issues caused by hardware or driver faults.
Adjusting screen brightness is unrelated to USB connectivity. Display settings do not influence the detection of external devices or the operation of the USB controller. Changing brightness will not resolve device recognition issues and is not a relevant troubleshooting step.
Creating a new local user account can help if profile-specific settings are causing detection problems, but this is unlikely to be the first step. Most USB detection issues are hardware-related, and creating a new account would not address problems with cables, ports, or power delivery to the device. It is more appropriate to address basic hardware functionality first.
The reasoning for verifying the USB cable and port first is that it targets the most common and simplest cause of detection failures. Checking physical connectivity is efficient, non-invasive, and often resolves the issue immediately. This approach follows standard troubleshooting methodology, starting with basic hardware verification before moving to software, driver, or system configuration adjustments. Ensuring the physical connection is functional reduces unnecessary steps and provides a clear path for further troubleshooting if needed.
Question 36
A technician is setting up a new Windows workstation for multiple users. Which feature allows each user to have personalized settings and files without affecting others?
A) User accounts
B) Disk Cleanup
C) Device Manager
D) Task Scheduler
Answer: A) User accounts
Explanation:
User accounts in Windows allow multiple individuals to share a single computer while maintaining separate profiles, settings, and files. Each user account can have its own desktop configuration, preferences, documents, and application settings, which ensures that one person’s changes or files do not interfere with another’s. User accounts also allow administrators to assign different permission levels, such as standard user or administrator, controlling what actions each person can perform on the system. This feature is essential for environments where multiple people access the same workstation, such as offices, classrooms, or shared computers in homes.
Disk Cleanup is a utility used to remove unnecessary files, temporary files, system caches, and other data to free up storage space. While Disk Cleanup improves performance and storage efficiency, it does not provide personalized settings for individual users or isolate data between multiple accounts. Using Disk Cleanup cannot replicate the functionality of separate user profiles and does not manage permissions or access control for different individuals.
Device Manager is a tool for managing hardware devices and their drivers. It allows technicians to troubleshoot hardware issues, update drivers, and verify device functionality. While essential for system maintenance, Device Manager does not create or manage user profiles, personalize settings, or separate files between users. It is focused entirely on hardware configuration rather than software or user-level customization.
Task Scheduler automates the execution of programs, scripts, or system tasks at specified times. Although Task Scheduler can help manage recurring maintenance tasks or updates, it does not provide individualized profiles or separate settings for different users. Tasks can be run under different user accounts, but it does not isolate desktop configurations, personal files, or application preferences.
The reasoning for selecting user accounts is that they directly address the requirement of allowing multiple users to share a single computer while maintaining personalized settings and files. By providing each user with a unique account, the system ensures security, privacy, and convenience. Changes made by one user do not affect others, and administrators retain control over permissions and access. This approach is fundamental in multi-user environments and forms the basis of personalized experiences, data protection, and system organization. Using user accounts also supports additional security features, such as password protection and parental controls, which further enhance system management and user safety. Proper implementation of user accounts prevents conflicts, data loss, or accidental misconfiguration, making it the most effective solution for managing multiple users on a single Windows workstation.

Answer: A) Ensure that air vents and fans are not blocked
Explanation:
Overheating is commonly caused by restricted airflow or malfunctioning cooling components. The first step in troubleshooting overheating is to check that air vents are not blocked and that fans are functioning properly. Dust buildup or obstruction can prevent heat from dissipating, causing components such as the CPU and GPU to exceed safe operating temperatures. Ensuring proper airflow and cooling allows the system to maintain stable temperatures during heavy use, preventing thermal throttling, sudden shutdowns, or hardware damage. This inspection is non-invasive and often resolves overheating without requiring software adjustments or component replacement.
Adjusting screen resolution can affect display performance and GPU load, but has minimal impact on overall CPU or system temperature. While lowering resolution may slightly reduce GPU stress, it is unlikely to resolve overheating caused by blocked vents, dust, or malfunctioning fans. Screen resolution adjustments are secondary measures and not the first step when addressing thermal issues.
Deleting temporary files improves storage efficiency and may enhance overall system performance, but it does not affect the temperature of hardware components. Temporary files exist on the storage drive and do not generate heat, so removing them will not resolve overheating. While storage management is important for long-term maintenance, it is not relevant for thermal troubleshooting.
Disabling User Account Control changes how Windows handles security prompts but has no effect on the system’s thermal performance. UAC affects application privileges and administrative tasks, not CPU, GPU, or fan operation. Turning off UAC does not address the root cause of overheating and could introduce security risks without solving the thermal problem.
The reasoning for checking air vents and fans first is that physical cooling is the primary factor in preventing overheating. Proper airflow ensures that heat generated by the CPU, GPU, and other components is effectively dissipated. This step targets the most common cause of overheating, providing an immediate and low-risk solution. By focusing on hardware cooling before software adjustments, the technician follows a methodical troubleshooting approach that prioritizes physical functionality, reduces the risk of component failure, and improves system reliability. Ensuring that vents and fans are unobstructed is a standard maintenance procedure and an effective first step in thermal management.

High CPU usage, memory saturation, or disk activity often causes slowdowns and can indicate malfunctioning software, memory leaks, or misbehaving applications. By identifying the resource-intensive process, the technician can take targeted actions such as terminating the process, updating the application, or adjusting system settings, which often resolves the performance issue efficiently.
Reinstalling the operating system immediately is a drastic step that is unnecessary as the first measure. A complete reinstallation is time-consuming, involves data backup and restoration, and may disrupt user workflows. Slowdowns are usually caused by software, processes, or resource contention, which can be diagnosed and addressed without reinstalling the OS. Reinstallation should only be considered after simpler troubleshooting methods, such as monitoring Task Manager, have failed.
Changing the desktop background has no impact on system performance. Display settings like wallpapers or screensavers do not affect CPU, memory, or disk utilization significantly. Adjusting the background is cosmetic and does not address the underlying causes of system slowness or unresponsive applications.
Disabling Bluetooth may reduce minor background processes related to wireless peripherals, but it does not target the main causes of system resource contention. Bluetooth services are usually lightweight, and turning them off will not significantly improve performance if the CPU or memory is already heavily utilized by other applications.
The reasoning for checking Task Manager first is that it provides immediate diagnostic insight into the processes responsible for performance degradation. It enables the technician to identify high-impact programs, verify system load, and take corrective measures without risking data loss or unnecessary system changes. Task Manager allows targeted intervention, following best practices in system troubleshooting by addressing the most likely causes efficiently.

Checking the wireless adapter settings ensures that the device is enabled, configured to connect automatically to known networks, and not set to turn off to save power. Additionally, updating drivers ensures that the adapter is running the most current firmware compatible with the operating system. Drivers are essential because they allow Windows to communicate effectively with the wireless hardware, handle protocols correctly, and manage power settings. Outdated drivers can lead to instability, frequent disconnects, or reduced performance, making this the most logical first step in troubleshooting connectivity issues.
Updating Microsoft Office affects productivity applications such as Word, Excel, and Outlook. While keeping Office current is important for feature updates and security patches, it does not influence Wi-Fi connectivity. Office updates do not interact with networking hardware or drivers, so they would not resolve frequent disconnections. This makes updating Office irrelevant for this particular issue, and focusing on it would waste time without addressing the root cause.
Changing the desktop background is purely cosmetic. Desktop images and themes have no impact on the functioning of the network adapter, signal strength, or driver communication. Adjusting the wallpaper or screensaver will not affect connectivity, and it is unrelated to the underlying problem causing intermittent Wi-Fi disconnections. Any time spent changing display settings would not improve the user’s network experience or address system stability.
Defragmenting the hard drive is a process that reorganizes data on mechanical drives to improve access times. While useful for maintaining system performance, it does not influence network connectivity, driver behavior, or wireless signal stability. Defragmentation is unrelated to Wi-Fi adapter functionality and will not resolve disconnection issues. Performing this step does not address the immediate need for stable wireless communication.
The reasoning for checking the wireless adapter settings and drivers first is that this approach directly addresses the most common causes of Wi-Fi instability. By verifying the adapter configuration, ensuring it is enabled, and updating drivers, the technician can restore proper communication between the operating system and the network hardware. This method is efficient, non-invasive, and likely to resolve the issue without unnecessary changes to unrelated software or system settings. It also aligns with best practices in troubleshooting, which emphasize addressing the most probable cause first while minimizing risk.

A) Scan for malware and remove threats
B) Uninstall Microsoft Office
C) Adjust the screen resolution
D) Disable User Account Control
Answer: A) Scan for malware and remove threats
Explanation:
Frequent pop-ups prompting users to install unknown software are a strong indicator that the system is infected with malware or adware. The first step is to perform a full system scan using updated antivirus or anti-malware software. Scanning allows the detection, quarantine, and removal of malicious files or processes causing the pop-ups. This approach is non-invasive, does not risk user data, and directly targets the source of the problem. Malware and adware often operate in the background, creating unwanted notifications, modifying browser settings, or attempting to trick users into installing additional harmful programs. Identifying and removing these threats ensures system security, restores normal operation, and prevents further infection or data compromise.
Uninstalling Microsoft Office would not address the root cause of the pop-ups. Office software is unrelated to the execution of adware or malicious pop-up programs. While malware may target Office files for ransomware attacks, simply uninstalling Office does not remove the malicious programs responsible for the frequent pop-ups. This action would disrupt user productivity without solving the underlying security issue.
Adjusting the screen resolution is a visual and display-related setting that has no impact on malware infections or adware pop-ups. Changing the resolution affects only how content is rendered on the screen, not how malicious programs execute or display notifications. Attempting to adjust display settings would not resolve the frequent installation prompts and would be irrelevant to addressing malware-related behavior.
Disabling User Account Control changes how Windows prompts for administrative permissions when executing programs. While turning off UAC reduces security prompts, it does not remove malware or adware causing unwanted pop-ups. Disabling UAC could actually reduce system protection, making it easier for malicious programs to execute without restrictions. This approach would increase risk rather than resolving the problem, and it does not address the actual source of the pop-ups.
The reasoning for scanning for malware first is that it targets the most likely cause of the problem efficiently and safely. Malware infections are the primary source of unsolicited pop-ups, and removing them eliminates the unwanted behavior. Using antivirus software ensures that threats are detected systematically and removed according to best practices, preserving system integrity and user data. This step also prevents escalation of infection, which could lead to data loss, credential theft, or more severe system instability. Starting with a malware scan follows a methodical troubleshooting approach, addressing the root cause before making unnecessary changes to unrelated software, settings, or security configurations. This ensures the problem is resolved comprehensively, restoring normal system operation and maintaining user security without unnecessary disruption. By prioritizing malware detection and removal, the technician addresses both the immediate issue of pop-ups and the potential long-term impact of the infection.
Question 43

A) Disable unnecessary startup programs using Task Manager
B) Adjust the screen resolution
C) Increase virtual memory
D) Uninstall Microsoft Office
Answer: A) Disable unnecessary startup programs using Task Manager
Explanation:
A computer taking a long time to start up is often caused by an excessive number of programs and services configured to run automatically during login. Disabling unnecessary startup programs through Task Manager is the most effective first step because it directly targets the processes that consume CPU, memory, and disk resources during boot. By opening Task Manager and navigating to the Startup tab, the technician can view a list of applications set to launch at startup and evaluate their impact using the startup impact column, which measures resource usage. Disabling high-impact, non-essential programs prevents them from running automatically, reducing boot times and improving overall system responsiveness.
Adjusting the screen resolution affects how the display renders content and may influence GPU load during normal use, but it does not affect the startup process. Resolution changes are cosmetic and do not control which programs or services load during system startup. While lowering resolution may slightly reduce GPU activity, it is not a solution for boot delays caused by resource-heavy startup applications. Focusing on resolution does not address the root cause and would not yield a significant improvement in boot times.
Increasing virtual memory allows Windows to use a portion of the hard drive as supplemental RAM. While this can improve system performance during memory-intensive operations, it does not affect which programs load during startup or reduce boot time. Virtual memory management is a performance optimization measure, but it is not targeted at resolving slow startup due to excessive background applications. Using virtual memory adjustments as the first step is inefficient when startup performance issues are caused primarily by unnecessary software loading.
Uninstalling Microsoft Office may free up disk space, but Office applications generally do not impact boot performance unless specific add-ins or background services are running at startup. Removing Office is a drastic step that affects productivity and is not necessary to address startup delays. The majority of performance improvement comes from controlling programs that actively execute during login rather than removing large but mostly inactive applications.
The reasoning for disabling unnecessary startup programs first is that it directly addresses the most common cause of slow startup and is both non-invasive and reversible. Task Manager allows the technician to make informed decisions about which programs are essential and which can be safely disabled without impacting system functionality. This approach follows best practices by resolving the underlying cause efficiently and without disrupting the operating system or user productivity. By optimizing startup applications, the technician can achieve immediate performance gains, ensure smoother boot processes, and avoid unnecessary software removal or system modifications. This method aligns with standard troubleshooting methodology, targeting high-impact factors first while minimizing risk. Controlling startup programs is the most effective initial step in improving Windows startup performance because it addresses resource consumption at the root of the issue, providing measurable improvements without compromising system stability or user workflow.

A) Check Task Manager for processes consuming high CPU or memory
B) Reinstall Microsoft Office
C) Adjust the desktop background
D) Disable Windows Defender
Answer: A) Check Task Manager for processes consuming high CPU or memory
Explanation:
When a Windows 10 computer runs slowly during multitasking, the first step should be to examine resource usage using Task Manager. Task Manager provides a real-time view of CPU, memory, disk, and network utilization, which allows the technician to identify processes consuming excessive resources. High CPU usage can result from poorly optimized applications, background services, or malware, while high memory usage can cause the system to use virtual memory, leading to sluggish performance and slow application switching. By monitoring Task Manager, the technician can determine whether the slowdown is due to a specific application, background process, or system component, and take targeted action to terminate unnecessary processes, adjust priorities, or manage startup programs.
Reinstalling Microsoft Office is unrelated to general system performance unless Office applications themselves are causing the slowdown. Most performance issues when multiple applications are open are caused by system resource contention rather than the presence of Office. Reinstalling Office would be time-consuming, disruptive, and unlikely to address the underlying problem. This approach does not align with standard troubleshooting methodology, which emphasizes identifying high-impact factors before performing invasive or unnecessary actions.
Adjusting the desktop background is purely cosmetic and does not influence CPU, memory, or disk usage significantly. Changing wallpapers or themes will not resolve issues caused by resource-intensive applications, and any perceived improvement would be coincidental rather than addressing the root cause of performance problems. Focusing on display settings is ineffective as a first step when diagnosing slowness due to multitasking or high resource usage.
Disabling Windows Defender may slightly reduce background system activity, but it is not a recommended first step because it exposes the system to security risks. Windows Defender runs in the background to monitor and protect the computer from malware, and temporarily disabling it may reduce CPU load, but the performance gains are generally minor compared to addressing the actual processes consuming high resources. Additionally, turning off critical security features creates a potential vulnerability without solving the root cause of the slowdown.
The reasoning for checking Task Manager first is that it provides a comprehensive and non-invasive method for diagnosing performance issues. By examining resource usage, the technician can quickly identify which applications or services are responsible for excessive CPU or memory consumption, allowing for precise corrective action. This step follows the principle of starting with the simplest, most likely causes before resorting to disruptive measures such as software reinstallation or disabling security features. Task Manager also provides insight into whether the issue is temporary, such as a one-time spike in usage, or persistent, indicating a need for long-term optimization strategies such as adjusting startup programs, updating drivers, or upgrading hardware. Addressing the root cause identified in Task Manager ensures that the technician can improve system performance safely and efficiently, while minimizing disruption to the user. By targeting high-impact processes, overall system responsiveness is restored, allowing users to run multiple applications simultaneously without experiencing significant lag or instability. Task Manager acts as both a diagnostic and management tool, enabling proactive maintenance, resource balancing, and identification of potential malware or misbehaving applications that could be contributing to slowdowns. This step adheres to best practices in Windows troubleshooting, providing a clear, methodical, and effective approach to improving system performance in a multitasking environment.
