CompTIA 220-1102 - CompTIA A+ Certification Core 2 Exam

For a single user who needs to access their computer remotely, the Windows 10 Pro edition is the most cost-effective and appropriate choice. It includes features such as Remote Desktop, which are essential for remote access.

Option A: EducationThis edition is designed for academic institutions and includes educational features. It is not the most cost-effective for a single user.

Option B: ProWindows 10 Pro includes Remote Desktop and other business features. It is suitable and cost-effective for single users needing remote access.

Option C: EnterpriseThis edition includes advanced features for large organizations and is more expensive, making it less cost-effective for a single user.

Option D: HomeWhile cost-effective, Windows 10 Home does not include the Remote Desktop feature, making it unsuitable for this requirement.

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.

Detailed Explanation with Core 2 References:Using a private browsing window can help resolve session conflicts by not relying on cached credentials, which might interfere with single sign-on processes. Core 2 objectives include troubleshooting authentication issues and resolving potential conflicts with single sign-on systems (Core 2 Objective 4.7)​.

In this scenario, the user cannot access a separate subnet, and all other checks (credentials, network stability, and permissions) have been verified. The next logical step is to check if the user's IP address is being blocked by a firewall.

Option A: Consult with the firewall team to see if the user's IP address is blockedFirewalls can block specific IP addresses, preventing access to certain network segments. Given the problem's nature and the steps already taken, this is the most logical next step to ensure the user's IP is not inadvertently blocked.

Option B: Delete the user’s credentials and create new onesThis step is unnecessary since the credentials have already been verified as correct.

Option C: Run a virus scan on the user's workstationWhile important for overall security, a virus scan is unlikely to resolve an issue specific to accessing a subnet if the problem does not affect other users.

Option D: Update the network drivers on the user’s workstationIf the network connection is stable and the issue is isolated to accessing a specific subnet, network drivers are unlikely to be the cause.

To minimize impact on users and control costs, scheduling backups after peak hours reduces network and system load during busy times, ensuring business operations aren’t disrupted. Using the built-in Windows backup utility leverages existing tools without additional software expenses. Running backups when users log in can delay user activities. Installing backup software on every workstation increases complexity and cost. Frequent hourly backups may overload systems and create excessive storage use. Core 2 operational procedures emphasize efficient scheduling and cost-effective solutions like built-in OS tools to meet backup policy objectives.

When a system drive is nearly full, the most appropriate tool to free up space is Disk Cleanup. This built-in Windows utility scans the drive and allows users to safely remove temporary files, system cache, recycle bin contents, and other unnecessary files that consume disk space. Resource Monitor provides detailed real-time system resource usage but does not free space. Disk Defragment reorganizes fragmented files to improve performance but does not delete data. Disk Management is used to partition and format drives but does not clean files. Disk Cleanup is a primary maintenance tool covered in the Core 2 operating system domain to manage storage and optimize system performance.

Avoiding personal interruptions (such as browsing social media) shows respect and attentiveness, which is critical in building trust during customer interactions. Actively listening and taking notes demonstrates that the technician values the customer's concerns and is committed to resolving issues. Following up (A) and clarifying statements (D) are good but not immediate communication techniques during the interaction. Providing documentation (C) and maintaining attire (F) are operational but less relevant to active listening. Core 2 operational procedures highlight active listening and avoidance of distractions as key customer service skills to improve technician-customer communication.

The appropriate method to prevent unauthorized access to sensitive data is to wipe the drives (Option C). Wiping ensures that all data is securely erased, preventing any possibility of recovery. This is essential when handling drives containing Personally Identifiable Information (PII).

Degaussing (Option A) erases data but is more commonly used for magnetic tapes.

Drilling through the drives (Option B) physically destroys the drives, which may not be necessary if they are being reused.

Reimaging (Option D) would overwrite the current data with new data but may not guarantee complete data destruction.

BitLocker is a full-disk encryption feature included with certain editions of Windows, designed to protect data by providing encryption for entire volumes.

Option A: FileVaultFileVault is a disk encryption program in macOS, not Windows.

Option B: BitLockerBitLocker is the correct tool for disk encryption on Windows operating systems, providing full disk encryption.

Option C: Private KeyA private key is part of public key infrastructure (PKI) used in encryption, but it is not a tool for disk encryption by itself.

Option D: PowerShellPowerShell is a task automation and configuration management framework from Microsoft, not a tool for disk encryption.

The most likely solution to this issue is to enable cellular data. After a business trip, the user may have disabled cellular data to avoid roaming charges, or the phone may have been set to Wi-Fi only for internet access. Enabling cellular data would restore internet access outside of Wi-Fi networks.

In criminal proceedings, maintaining the integrity of evidence is crucial. The document that must be updated every time evidence is handled or transferred is:

Chain of custody: This document tracks the history of the evidence, detailing every person who has handled it and every transfer that has occurred. It ensures that the evidence has not been tampered with and maintains its validity in court.

Licensing agreement: Pertains to software usage rights and has no relation to evidence handling.

Regulatory compliance: Refers to adherence to laws and regulations, not evidence tracking.

Incident documentation: Details the incident but does not specifically track evidence handling.
