Pass the CompTIA A+ 220-1102 Questions and answers with ValidTests

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.

To manually add a workstation to a domain, the technician needs to access the System Properties menu where domain settings are configured.

User Accounts: Manages user accounts but does not handle domain membership.

System Properties: The correct place to add or change domain membership settings.

Windows Firewall: Manages firewall settings but not domain membership.

Network and Sharing: Manages network connections and sharing but not domain settings.

To securely access shared files and corporate email from home, the best tool to use is a Virtual Private Network (VPN). Here’s why:

VPN (Virtual Private Network): A VPN creates a secure connection over the internet, allowing the user to access the corporate network as if they were on-site. It encrypts the data transmitted between the user's home and the corporate network, ensuring privacy and security.

MSRA (Microsoft Remote Assistance): Used for remote support but not for accessing shared files and emails securely.

FTP (File Transfer Protocol): Used for transferring files but does not provide secure access to a corporate network or email.

RMM (Remote Monitoring and Management): Used by IT professionals to manage client systems remotely but not for user access to shared files and emails.

Random restarting of an Android phone and the presence of applications not from the standard marketplace strongly suggest the possibility of malware.

Option A: The OS update failedWhile an OS update failure can cause issues, it is less likely to result in random restarts compared to malware.

Option B: The user downloaded malwareMalware is a common cause of erratic behavior, including random restarts, especially when applications are installed from unofficial sources.

Option C: The device is in developer modeDeveloper mode alone does not typically cause random restarts. It may make the device more susceptible to issues if improper apps are installed.

Option D: The over-the-air carrier update failedSimilar to the OS update, this would more likely cause consistent issues rather than random restarts.

Disk encryption is the best method for securing a workstation used in financial transactions, such as point-of-sale systems. It ensures that if the workstation is stolen, all data on the disk is encrypted and cannot be accessed without proper credentials. File encryption (B) only encrypts individual files, and USB drive encryption (C) only applies to removable storage. Data-in-transit encryption (A) is not relevant for physical security.

When a legacy application is not fully functional after upgrading the Windows operating system, the first step to troubleshoot the issue is to:

Run the application as Administrator: Legacy applications often require administrative privileges to run correctly. Running the application with these privileges can resolve issues related to permissions and access to certain system resources.

Raise the User Account Control level: This increases security prompts but does not resolve compatibility issues.

Turn off Windows Defender Firewall: This can expose the system to security risks and is unlikely to resolve application functionality issues.

Disable compatibility mode for the application: Compatibility mode should generally be enabled for legacy applications to ensure they run properly on newer OS versions.

When a user reports slow performance, a changed home page, and pop-up ads, these are classic signs of malware infection. The first step should be:

Update the antivirus program and run a full system scan: This helps identify and remove any malware present on the system, addressing the root cause of the issues.

Uninstall the suspicious search engine and reset the home page: This addresses the symptom but not the underlying cause, which is likely malware.

Install the latest updates for the operating system: Important for security but secondary to removing malware.

Block the pop-up ads using the web browser settings: Again, addresses the symptom but not the root cause.

Enabling an allow list (Option D) will limit access to the wireless network by only allowing devices with specified MAC addresses to connect. This is an effective method for minimizing Wi-Fi access in a crowded environment.

Port forwarding (Option A) controls traffic through specific ports but doesn't minimize wireless access.

Unused ports (Option B) could refer to physical network ports or firewall settings, unrelated to controlling Wi-Fi access.

Disabling SSID broadcast (Option C) might hide the network name but doesn't secure access.

A battery backup, also known as an uninterruptible power supply (UPS), is a device that provides backup power during a power outage. When the power goes out, the battery backup provides a short amount of time (usually a few minutes up to an hour, depending on the capacity of the device) to save any work and safely shut down the equipment.

The Windows Professional Edition is the most likely version that a technician would deploy for a user at a target corporation. This version of Windows is designed for business use and provides the necessary features and capabilities that a user would need to access the corporate domain, such as email and shared drives.

The most likely reason the computer is unable to boot into the imaging system via the network is that the PXE boot option has not been enabled. PXE (Preboot Execution Environment) is an environment that allows computers to boot up over the network, instead of from a local disk. In order for this to work, the PXE boot option must be enabled in the computer's BIOS settings. As stated in the CompTIA A+ Core 2 exam objectives, technicians should know how to enable PXE in BIOS to enable network booting on a computer.

The technician's action of setting the phone to silent while troubleshooting the customer's PC is an example of avoiding distractions. By setting the phone to silent, the technician is ensuring that they are able to focus on the task at hand without any distractions that could potentially disrupt their workflow. This is an important practice when handling customer's confidential material, as it ensures that the technician is able to focus on the task and not be distracted by any external sources. Furthermore, it also adheres to user privacy policies, as the technician is not exposing any confidential information to any external sources.

The technician should check the Wi-Fi connection speed first to troubleshoot this issue. Slow web browsing speed on a mobile phone can be caused by a slow Wi-Fi connection. The technician should check the Wi-Fi connection speed to ensure that it is fast enough to support web browsing. If the Wi-Fi connection speed is slow, the technician should troubleshoot the Wi-Fi network to identify and resolve the issue.

The risks in running this script are that the deployment script is performing unknown actions. Running the script blindly could cause unintended actions, such as deploying malware or deleting important files, which could negatively impact the organization’s network and data1.

When a user reports that their workstation is behaving strangely after opening a suspicious email, the first step a technician should take is to run a virus scan on the computer. This is because opening a suspicious email is a common way for viruses and malware to infect a computer. Running a virus scan can help identify and remove any infections that may be causing the computer to behave strangely.

The technician should use the File Explorer application to assist the user with hiding the file 1. The user can right-click the file and select Properties. In the Properties dialog box, select the Hidden check box, and then click OK 1.

A rootkit (Option A) is a type of malware designed to gain administrative (root) access to a system while hiding its presence. Rootkits can manipulate system processes and files to remain undetected, making them particularly dangerous.

Trojan (Option B) is malware disguised as legitimate software but doesn't necessarily provide administrative access.

Worm (Option C) spreads across networks but doesn't grant administrative access.

Ransomware (Option D) encrypts data and demands a ransom but doesn't typically provide ongoing administrative access.

The correct answers are B. .pkg and F. .dmg.

pkg (Package Installer) – This is the standard macOS package format for software installations. It often includes installation scripts and can be used for software distribution.

dmg (Disk Image File) – A macOS disk image file that contains software installers. Users typically mount the file and drag the application into the Applications folder to install it.

Why Other Options Are Incorrect:

A. .yum – This is used for Linux package management and is not compatible with macOS.

C. .msi – This is the Windows Installer package format, not used on macOS.

D. .ps1 – This is a PowerShell script file used in Windows, not for installing macOS applications.

E. .exe – This is an executable file format for Windows applications and does not run on macOS without third-party emulation (e.g., Wine).

The technician should instruct the user to clear the browser cache and contact the bank (option A). This error indicates that the website the user is visiting is not the correct website and is likely due to a cached version of the website being stored in the user's browser. Clearing the browser cache should remove any stored versions of the website and allow the user to access the correct website. The user should also contact the bank to confirm that they are visiting the correct website and to report the error.
