CompTIA 220-1102 CompTIA A+ Core 2 Exam Practice Test

Answer : B

Checking running applications (Option B) is the best first step, as background apps consume CPU, RAM, and battery. Identifying and closing resource-heavy apps can immediately improve performance and battery life.

Uninstall unused programs (Option A): Helps free up storage, but it does not address performance and battery drain as directly as managing running apps.

Update the mobile OS (Option C): Important but may not provide immediate relief, and updates sometimes cause additional issues.

Disable network services (Option D): While turning off features like Wi-Fi or Bluetooth can save battery, it does not directly address slow performance.

Answer : C

Creating a domain and joining the workstations to it provides centralized management and control over the computers, making the environment much more manageable.

Here's why a domain is beneficial:

Centralized administration: Manage user accounts, security policies, software installations, and updates from a single location (the domain controller).

Group Policy: Implement and enforce security policies, configure system settings, and control user access to resources.

Simplified updates: Deploy software updates and patches to multiple computers simultaneously.

Improved security: Enforce stronger password policies, control access to sensitive data, and enhance overall network security.

Here's why the other options are less suitable:

A . Downgrade all workstations from the Pro version to the Home version of the OS: The Home version has fewer features and management capabilities than the Pro version, making it less suitable for a business environment.

B . Upgrade all workstations from the Pro version to Pro for Workstations: While Pro for Workstations has advanced features, it's designed for high-performance tasks and might not be necessary for all users.

D . Make sure all workstations are operating under the same workgroup name: While being in the same workgroup allows for basic network sharing, it doesn't provide the centralized management capabilities of a domain.

Answer : C

Restarting a smartphone is a basic troubleshooting step that often resolves temporary software glitches or minor errors that might be preventing the screen rotation from working correctly. It's a quick and easy step to try before moving on to more complex solutions.

Here's why the other options are not the best first step:

A . Remove the screen protector: While a thick or improperly installed screen protector could potentially interfere with the sensors responsible for screen rotation, it's less likely to be the cause.

B . Update the smartphone's software: While software updates can fix bugs and improve functionality, they are not always necessary for resolving a screen rotation issue.

D . Replace the smartphone: Replacing the smartphone is a drastic measure and should only be considered if other troubleshooting steps fail.

Troubleshooting Steps:

Restart the smartphone: This often clears temporary software issues.

Check for software updates: If a restart doesn't work, updating the operating system or any relevant apps might resolve the issue.

Calibrate the accelerometer: Some smartphones have a calibration tool for the accelerometer, the sensor that detects orientation. Check the device settings for this option.

Check for hardware issues: If the problem persists, there might be a hardware issue with the accelerometer or other components. In this case, contacting the manufacturer or a repair center might be necessary.

Answer : B

When dealing with sensitive information, it's crucial to adhere to company policies and procedures. These policies will outline the proper protocols for handling and transporting devices containing sensitive data.

Here's why the other options might not be the best course of action:

A . Remove the HDD and then send the computer for repair: While this might seem like a good way to protect the data, it might not be compliant with company policy. Some policies might require the entire device to be sent for security reasons or to ensure proper diagnosis and repair.

C . Delete the sensitive information before the computer leaves the building: Deleting the data might not be sufficient, as it could potentially be recovered. Also, it might violate data retention policies or hinder the repair process.

D . Get authorization from the manager: While getting manager approval is important, it's essential to first consult the company policies to understand the required procedures.

Recommended Steps:

Check corporate policies: Review the company's policies on data security, device handling, and off-site repairs.

Consult with IT security or management: If the policies are unclear or if you have any questions, seek guidance from the appropriate personnel.

Follow the prescribed procedures: This might involve data encryption, secure data wiping, obtaining necessary approvals, and using approved vendors for off-site repairs.

Answer : A

The nslookup command is a network administration tool used for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record. It's the most direct way to verify if a PC can resolve a website's domain name to its IP address.

Here's why the other options are not the primary tools for this task:

B . hostname: This command displays the hostname of the computer.

C . tracert: This command traces the route packets take to reach a specific destination. It can help identify network connectivity issues but doesn't directly test DNS resolution.

D . netstat: This command displays active network connections and listening ports. It's not used for DNS troubleshooting.

How to use nslookup:

Open a command prompt.

Type nslookup <website address> (e.g., nslookup google.com) and press Enter.

The output will show the DNS server used and the IP address(es) associated with the website.

If the command returns an error or doesn't show an IP address, it indicates a problem with DNS resolution.

Answer : B

The 'Error loading operating system' message in Windows typically indicates a problem with the boot process. This could be due to corrupted system files, boot configuration data (BCD) errors, or issues with the hard drive.

Windows has a built-in automated startup recovery tool designed to diagnose and fix these types of problems. It attempts to automatically find and repair issues that are preventing Windows from starting correctly.

Here's why the other options are not the best first step:

A . Disable the Secure Boot feature: Secure Boot is a security feature that helps prevent malware from loading during startup. While it can sometimes cause issues with incompatible hardware or software, it's unlikely to be the primary cause of this error after a Windows upgrade.

C . Format the drive: Formatting the drive should be a last resort as it will erase all data on the hard drive.

D . Resize the boot partition: Resizing the boot partition is a complex task and not usually necessary to fix a boot error.

Troubleshooting Steps:

Use the automated startup recovery:

This is usually attempted automatically when Windows fails to boot.

If it doesn't start automatically, you might need to access the Advanced Startup Options menu (usually by repeatedly pressing F8 or Shift+F8 during startup).

If automated repair fails, try other options from the Advanced Startup Options menu:

System Restore: Restore the system to a point before the upgrade.

Startup Repair: This tool can fix more complex boot errors.

Command Prompt: Use the command prompt to run commands like bootrec /fixmbr, bootrec /fixboot, and bootrec /rebuildbcd to repair the boot configuration.

Answer : A

Full Comprehensive In this situation, the priority is to get the workstation back online and accessing the corporate database as quickly as possible. Restoring from the last backup is the most efficient way to achieve this. It will revert the system to a known working state, likely resolving the software issue without the need for extensive troubleshooting.
