220-1202 CompTIA A+ Core 2 (2026 Exam Update) Question and Answers

The correct syntax for mapping a network drive in Windows is:

net use Z: \\WinNAS\shared

This command connects the specified network share and maps it as drive Z:.

FromTravis Everett – CompTIA A+ All-in-One Exam Guide:

“Use net use followed by the desired drive letter and the UNC path to map network shares.”

The best first step is to leverage existing documentation: check whether the issue was previously recorded and resolved, and reuse that known fix (or confirm conditions). Mike Meyers explains ticketing systems capture key information needed to resolve issues, including “ problem description ,” “ progress notes ,” and “ problem resolution ,” and stresses that “ Clear, concise writing is critical ” because you “won’t be the only tech responding to every ticket.” That is exactly why you review prior tickets first—so you can quickly see what was done previously and apply it consistently.

The All-in-One guide reinforces the same ticketing-system concept and lists the same essential elements (description, notes, resolution) used to streamline troubleshooting and escalation. Consulting the prior technician (A) may be impossible (the employee is gone) and slower than checking documented history. Opening a new case (D) is important, but the question asks what to do first —review the prior occurrence details, then document your current case using what you find.

A “central log-in” means users can authenticate using a centralized account database rather than separate local accounts on each PC—this is a core feature of a Windows domain . Mike Meyers explains that a Windows domain makes it easy for anyone with a domain account to log on to any computer in the domain with a single account , a process called “single sign-on (SSO),” and that users do not need a separate local account stored on every computer. The All-in-One guide reinforces the same: in a domain, the domain controller stores domain accounts and “a user logging on to any computer on the domain may use their one domain account to log on to the entire network.”

Active Directory is the directory service commonly used to implement domains, but the question asks what is required for centralized logon on the workstation side— the computer must be joined to the domain (domain membership). Workgroups use only local accounts, and Local Group Policy Editor manages policies locally, not centralized authentication.

The correct answer isVNC (Virtual Network Computing). VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It is platform-independent and widely supported on Linux, which makes it ideal for providinginteractive remote support for a Linux-based operating system. It allows the technician not only to view the remote desktop session but also tocontrol it, fulfilling the need to see and interact with the user’s session.

A. VPN(Virtual Private Network) creates a secure tunnel to a network but doesnot provide desktop sharing or session controlby itself.

C. SSH(Secure Shell) provides secure command-line access to Unix/Linux systems but does not offergraphical desktop interaction, which is a requirement in this case.

D. RDP(Remote Desktop Protocol) is primarily a Microsoft protocol, and although it can be made to work on Linux, it isnot natively supported on legacy Linux systems, and thusless suitablethan VNC in this scenario.

CompTIA A+ 220-1102 Core 2 Objective Reference:

Objective 1.8 – Given a scenario, use features and tools of the operating system.

Under this objective, candidates are expected to be familiar with remote access technologies, includingRDP, SSH, and VNC, and understand their appropriate uses and limitations on different platforms such as Windows and Linux.

The correct answer is C. man, which stands for manual. The man command is used in Linux and UNIX-based operating systems to display the official documentation for commands, configuration files, and system calls. This documentation includes descriptions, syntax, available options, and usage examples.

The Quentin Docter – CompTIA A+ Complete Study Guide explains that Linux relies heavily on built-in documentation accessible from the command line. The man pages are considered the authoritative reference for how a command works and what options it supports. For example, running man cp displays documentation for the file copy command.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that learning to use man is essential for Linux administration and troubleshooting. Unlike graphical help systems, man pages are always available locally and do not require internet access.

The Mike Meyers / Mark Soper Lab Manual clarifies that chmod changes file permissions, cat displays file contents, and sudo allows commands to be run with elevated privileges. None of these commands provide documentation about other commands.

Because the question specifically asks about reading another command’s documentation, the Linux command designed for that exact purpose is man, making C the correct answer.

An Acceptable Use Policy (AUP) outlines the rules and guidelines for employees or users regarding the appropriate use of company systems, resources, and internet access. It defines permitted and prohibited activities, helping to mitigate security risks and establish clear behavioral expectations.

B. MNDA (Mutual Non-Disclosure Agreement) deals with confidentiality, not usage guidelines.

C. DRM (Digital Rights Management) controls access to copyrighted content.

D. EULA (End User License Agreement) pertains to software licensing, not internal policies.

The correct answer is C. RDP (Remote Desktop Protocol), because RDP is the default remote access technology for Windows servers. It allows technicians to remotely connect to the graphical desktop environment of a Windows server to verify services, logs, and system status.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, RDP is built into Windows operating systems and is commonly used by administrators to manage Windows servers and workstations. It provides full access to the desktop, making it ideal for checking whether services such as IIS (Internet Information Services) are running properly.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that while SSH is commonly used for Linux and network devices, Windows servers typically rely on RDP for administrative access. VNC is a third-party remote desktop solution and is not enabled by default on Windows systems.

The Mike Meyers / Mark Soper Lab Manual reinforces that SPICE is primarily used in virtualized environments and is not a standard Windows remote access tool.

Because the technician needs to verify a Windows web server’s operational status using a built-in method, RDP is the most appropriate and likely technology, making C the correct answer.

The correct answer is B. Add the user to the local Administrators group, because this provides the necessary permissions to install software on a specific machine without granting excessive privileges across the entire domain. This approach follows the principle of least privilege while still allowing the user to perform required testing tasks.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, local administrator rights allow users to install and configure applications on a single system but do not grant access to domain-wide resources. This makes it an appropriate choice for sandboxed or test environments.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide warns against adding users to the Domain Admins group, as this grants full control over the entire Active Directory environment and poses a significant security risk. Sharing credentials or passwords violates security best practices and audit requirements.

The Mike Meyers / Mark Soper Lab Manual reinforces that granting local administrative access is a common and accepted practice in controlled testing scenarios, especially when systems are isolated from production environments.

Because the goal is to allow software installation without compromising domain security, adding the user to the local Administrators group is the best and safest option, making B the correct answer.

The correct answer is A. Perform a factory reset, because the symptoms strongly indicate a serious mobile malware infection, potentially including spyware or a trojan installed from an unofficial app store. Random pop-ups, excessive data usage, blocked access to banking apps, and inability to update the OS are classic indicators that malicious software has gained deep system-level access.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, mobile malware installed from unofficial sources can embed itself deeply into the operating system, sometimes gaining device administrator privileges. In such cases, standard remediation steps such as clearing cache or uninstalling apps may be ineffective.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that when a mobile device shows signs of persistent compromise—especially when core OS functions and security-sensitive applications are affected—the recommended first step is to perform a factory reset. This completely wipes user-installed applications and restores the device to a known-good state.

The Mike Meyers / Mark Soper Lab Manual reinforces that changing passwords is important after the device is secured, not before. Contacting support or clearing cache does not remove deeply embedded malware.

Therefore, to immediately address the security threat and regain control of the device, a factory reset is the most appropriate first action, making A the correct answer.

Carbon fiber filamentcan producefine particles or fumesduring printing, which may be harmful when inhaled. Wearing anair filter maskis essential to protect the respiratory system.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“When working with advanced materials like carbon fiber, always use appropriate personal protective equipment such as air filter masks to prevent inhalation of dangerous particles.”

The best answer is B because Linux, macOS, and Windows handle application installation differently, so the technician should use the correct tool or deployment method for each operating system. The A+ Core 2 objectives specifically include diverse OS environments, macOS application installation file types such as .dmg, .pkg, and .app , and Linux tools such as apt-get and yum . The Mike Meyers/Mark Soper material explains that macOS software may be installed from the App Store, a .dmg disk image, or a .pkg installer, while Linux commonly uses package-management tools and distro software stores. The All-in-One Exam Guide also emphasizes that package managers install and update software while handling dependencies, which is especially important in Linux. A single Windows batch script would not properly apply to macOS and Linux. Sending users to the manufacturer’s website bypasses organizational control, and manual installation on every system is inefficient and error-prone.

Within the Windows ecosystem, Microsoft introduced ReFS (Resilient File System) as the next-generation filesystem concept designed to improve integrity and resilience, particularly for large storage and fault-tolerant configurations. Among the options, XFS is a Linux filesystem, APFS is Apple’s modern filesystem, and exFAT is primarily intended for removable media compatibility—not as an NTFS successor.

In the provided CompTIA A+ practice material set, ReFS is explicitly identified as “Resilient File System (ReFS)” and discussed as a Windows storage/filesystem technology. This aligns with the exam framing that ReFS is the Windows-side “successor” concept compared with NTFS in capability and design goals for modern storage scenarios.

Therefore, the correct answer is ReFS (A).

The correct answer is B. exFAT, because exFAT (Extended File Allocation Table) is designed to provide cross-platform compatibility between Windows and macOS while supporting large files and large storage devices. When an external hard drive must be readable and writable by both operating systems without additional drivers or configuration, exFAT is the preferred choice.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, exFAT was developed to overcome the limitations of FAT32, such as file size and volume size restrictions, while maintaining broad operating system support. Both Windows and macOS include native support for exFAT, making it ideal for removable storage devices.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that NTFS is fully supported on Windows but only has limited or read-only support on macOS by default. APFS is Apple’s proprietary filesystem and is not natively supported by Windows. XFS is a Linux filesystem and is incompatible with both Windows and macOS without third-party tools.

The Mike Meyers / Mark Soper Lab Manual reinforces that for external drives shared across platforms, exFAT offers the best balance of compatibility, performance, and simplicity.

Therefore, exFAT is the best filesystem choice, making B the correct answer.

This is macOS “Gatekeeper”-style behavior: the OS warns when an app is not from a trusted source (for example, not signed/not from an identified developer). In Quentin Docter’s macOS section, the correct place to control what apps are allowed is Security & Privacy. He states that in Security & Privacy, “the applications downloaded on the device can also be controlled; you can select whether apps can be downloaded only from the App Store or from App Store And Identified Developers, which is the default.” He also notes many advanced settings in Security & Privacy require unlocking with an administrator password.

Although the exact control is on the General area of Security & Privacy (not the Privacy tab itself), among the answer choices the closest and intended match is Privacy (A) because it points to the correct macOS security settings area in System Preferences/System Settings. Accessibility and Finder do not manage app trust controls, and iCloud relates to syncing/account services rather than software signing enforcement.

User offboarding involves disabling the departing user ' s access to company systems and facilities. Two key tasks typically include:

Deactivating physical access credentials (e.g., key fobs or badges) to prevent unauthorized entry (B).

Suspending or disabling the user’s email account to prevent future use and to retain business communications (D).

A. Quarantining a hard drive is not standard unless malware or legal issues are involved.

C. Purging PII must follow legal retention policies; it ' s not typically an immediate offboarding task.

E. Disabling network ports may be relevant in some cases but is not a standard offboarding step.

F. Blocking MAC addresses is not typical unless the device is considered a security threat.

The correct answer is B. VNC . The key phrase is graphical interface access . VNC, or Virtual Network Computing, is a remote-control technology used to share and control graphical desktops. Quentin Docter’s Complete Study Guide explains that VNC is a remote control tool for desktop sharing, uses a client-server model, and allows remote control of the host where the VNC server is installed. The Mike Meyers/Mark Soper material also explains that SSH is excellent for command-line administrative tasks, but when full graphical desktop access is needed, a remote desktop application is required; VNC is identified as cross-platform and usable for remote graphical control. SSH provides secure command-line access, not a full graphical interface by default. WinRM is mainly a Windows remote-management technology. Telnet is an insecure text-based remote access protocol and should not be used for secure remote administration.

The correct answer is C. Switch the NIC settings from manual to automatic, which allows the computer to obtain an IP address dynamically from the DHCP server. When a static IP address is no longer required, reverting the network configuration to DHCP ensures the system integrates properly with the current network design.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, DHCP simplifies network management by automatically assigning IP addresses, subnet masks, gateways, and DNS settings. Leaving a static IP in place can cause address conflicts or connectivity issues, especially when the device is repurposed.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that DHCP reservations are used when a device must always receive the same IP address, which is unnecessary in this scenario. Creating exclusions or manually changing the static IP does not meet the requirement to remove static addressing altogether.

The Mike Meyers / Mark Soper Lab Manual reinforces that switching the NIC to automatic configuration is the correct way to return a system to standard network operation and avoid manual IP management.

Because the static IP is no longer needed, enabling DHCP by setting the NIC to automatic configuration is the correct solution, making C the correct answer.

Windows doesn ' t natively support many Linux file systems (like ext4).Reformatting to exFATmakes the drive readable/writable on both Linux and Windows.

FromAll-in-One Exam Guide:

“For cross-platform compatibility, exFAT is recommended as it supports large files and is recognized by Windows, macOS, and Linux (with exFAT drivers).”

The best tool is SSH (Secure Shell) because the scenario requires running command-line instructions on a remote network switch and capturing the text output. SSH provides a secure, encrypted remote terminal session (TCP port 22) that is commonly used to administer Linux/UNIX systems and networking equipment, making it ideal for switches that are typically managed through a CLI. Quentin Docter explicitly notes that ssh.exe launches the Secure Shell client and that it allows you to connect to a Linux/UNIX server or networking equipment, and he explains that SSH encrypts communications for secure text-console remote access. Mike Meyers’ Lab Manual reinforces that Telnet/SSH enable you to connect to a “server or fancy router” to run commands remotely, and that SSH is the secure modern alternative because the session is encrypted. The All-in-One guide also emphasizes SSH as the encrypted replacement for Telnet and highlights its use for remote command-line administrative tasks. By contrast, RDP and VNC are graphical remote-desktop tools, and WinRM is Windows-specific remote management rather than a standard switch-access method.

The correct answer is D. Internal wiki, because an internal wiki is specifically designed to store, maintain, and centrally manage organizational knowledge, including deployment procedures, configuration standards, and troubleshooting documentation. Large-scale software deployments require accurate, up-to-date, and version-controlled instructions that can be accessed by multiple technicians.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, organizations commonly use internal knowledge bases or wikis to document standard operating procedures (SOPs), deployment guides, and escalation paths. These platforms allow content to be updated quickly as procedures evolve, which is essential for complex deployments.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide emphasizes that internal wikis support collaboration and consistency. Unlike emails or files stored on individual systems, a wiki provides a single source of truth, reducing the risk of technicians following outdated or incorrect instructions.

The Mike Meyers / Mark Soper Lab Manual further explains that while file servers may store installation files and emails may contain announcements, neither is suitable for maintaining structured, searchable deployment documentation. A user’s desktop is never an appropriate location for organizational procedures.

Because large-scale deployments require centralized, standardized, and continuously updated documentation, the most appropriate reference location is an internal wiki, making D the correct answer.

Standard Operating Procedures (SOPs)guide technicians through consistent and complete processes, including documentation.

FromTravis Everett – All-in-One Exam Guide:

“SOPs ensure that all required steps—such as data collection and issue description—are followed in every support interaction.”

Group Policyis the standard administrative tool for setting user permissions across domain-joined systems.

FromQUENTIN DOCTER – COMPLETE Study Guide:

“Use Group Policy to enforce user rights, including disabling guest account access on domain computers.”

Least effort with correct access control is achieved by assigning permissions to a group and managing membership, rather than editing permissions user-by-user. Mike Meyers states this as a best practice: “ NTFS permissions are assigned both to user accounts and groups, although it’s considered a best practice to assign permissions to groups and then add user accounts to groups instead of adding permissions directly to individual user accounts. ” This reduces administrative overhead: once the group has the correct rights, adding/removing users is simple.

The CompTIA A+ practice rationale reinforces the same: “ Another best practice is to assign permissions to groups rather than users, and make users members of groups … as they change roles or positions.”

This question’s permission goal (“add,” “edit,” but “prevent deletion”) maps to carefully selected rights (for example, allow read/write/modify for needed actions while explicitly denying delete where appropriate), and the cleanest way is implementing that permission set once on a security group . Mapping drives (A) doesn’t enforce permissions by itself, admin rights (C) is excessive, and per-user permissions (D) is the most work.

AnNDA (Non-Disclosure Agreement)is used to ensure confidentiality of sensitive company information, especially when interacting with external parties.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“An NDA ensures that confidential information is not disclosed to unauthorized individuals, especially important in external communications.”

The correct answer is C. Setting up image deployment for PXE, because PXE (Preboot Execution Environment) allows operating system installations and upgrades to be performed over the network without using removable storage. Since all removable media is disabled for security reasons, PXE-based deployment preserves existing security controls while enabling centralized OS upgrades.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, PXE is commonly used in enterprise environments to deploy or upgrade operating systems at scale. PXE works by booting client machines from a network interface and pulling installation images from a secured deployment server.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that PXE is especially valuable when USB drives and external media are restricted. It ensures consistency, reduces human error, and maintains compliance with organizational security policies.

The Mike Meyers / Mark Soper Lab Manual reinforces that copying ISO files locally still requires write access and may violate security baselines. External drives are explicitly prohibited, and hardware tokens are authentication tools—not deployment mechanisms.

Because PXE enables secure, centralized, removable-media-free OS upgrades, it is the most appropriate solution, making C the correct answer.

The correct answer is D. cp, which is a core Linux command used to copy files and directories. File management in Linux is performed primarily through command-line utilities, and cp is one of the most fundamental commands for this purpose.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, Linux administrators frequently use commands such as cp, mv, rm, and ls to manage files. The cp command allows users to copy files between directories or locations and supports options for recursive copying and permission preservation.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide highlights that Linux file management commands differ significantly from Windows equivalents. While Windows uses robocopy and xcopy, Linux relies on simpler, built-in commands like cp.

The Mike Meyers / Mark Soper Lab Manual further explains that curl is used for transferring data over network protocols, not for managing local files. Commands such as robocopy and xcopy are Windows-specific and not available in standard Linux environments.

Because the question asks specifically about managing files in Linux, and cp is a native Linux file-management command, D is the correct answer.

A low-level format (also referred to as a zero-fill or full format) writes over every sector on a storage device, effectively destroying the existing data and making recovery nearly impossible. Unlike degaussing, which renders the drive unusable, a low-level format maintains the integrity of the device, allowing it to be repurposed or reused.

A. Deleting partitions does not fully erase data; it only removes references in the partition table.

B. EFS (Encrypting File System) encrypts files but does not securely wipe them.

D. Degaussing destroys the magnetic structure of a drive, making it inoperable and not reusable.

The user needs to deliver a project status presentation to external stakeholders, which implies hosting a meeting with screen sharing, invitations, and attendee management. Quentin Docter defines videoconferencing as screen-sharing software that allows more than one person to share screens and includes “additional functionality, such as calendar invite, call-in numbers, and attendee management.” He lists Microsoft Teams, WebEx, Zoom, and GoToMeeting as examples and states these tools “are often used to present ideas and collaborate between groups of people.” That exactly matches presenting to external stakeholders.

The other options don’t fit the requirement: WinRM is a Windows remote management protocol (administration, not presentations), RMM is used by IT providers to manage many systems remotely (not stakeholder presentations), and secure file transfer is for moving files rather than delivering a live presentation. Since videoconferencing platforms commonly provide screen sharing, chat, and meeting controls designed for external audiences, Videoconferencing (C) is the correct software type.

Linux is an open-source operating system that is freely available and does not require traditional licensing fees. It is highly versatile and scalable, making it suitable for both workstations and servers. Many enterprise environments use Linux to reduce software costs and benefit from robust server features.

B. Windows requires per-device or per-user licensing for both workstation and server editions.

C. macOS is proprietary and limited to Apple hardware with licensing restrictions.

D. Chrome OS is designed for lightweight devices and lacks server functionality.

BSOD after driver installation suggests a compatibility issue.Safe Mode allows rollback of driversthat may be causing the crash.

FromTravis Everett – CompTIA A+ All-in-One Exam Guide:

“If a BSOD occurs after a driver update, boot into Safe Mode and roll back to the previous driver version to restore system stability.”

The correct answer is D. Check the sources the AI tool is using for copyrighted content, because legal and ethical use of AI-generated code depends on ensuring the output does not violate copyright or licensing restrictions. Developers are responsible for verifying that code used in their applications complies with intellectual property laws.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, responsible and appropriate use of AI tools includes validating outputs for accuracy, legality, and compliance. AI systems may generate code that resembles copyrighted or licensed material if their training data includes such sources.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that simply crediting an author or adding comments does not automatically grant legal permission to use copyrighted code. Developers must ensure that the generated code is either original, properly licensed, or permitted for use under open-source or fair-use terms.

The Mike Meyers / Mark Soper Lab Manual reinforces that silently using generated code without verification can expose organizations to legal risk, including copyright infringement claims. Ethical AI usage requires due diligence before deploying generated outputs into production systems.

Because the question asks for the best legal choice, verifying the AI tool’s sources and licensing is the most appropriate action, making D the correct answer.

Highmemory usage (97%)suggests the system is overloaded with active processes. The technician should close unneeded applications to free up RAM and improve performance.

FromMike Meyers ' Lab Manual:

“When memory usage is near capacity, close all non-essential programs. This can dramatically improve response time without needing hardware upgrades.”

This is a classic symptom of graphics performance limitations: modern games stress GPU/VRAM far more than older or lightweight titles. The All-in-One guide explains that “graphically demanding applications… state specific graphics requirements,” and highlights that CompTIA focuses on “dedicated graphics cards versus integrated ones.” It further clarifies that integrated GPUs are typically less powerful than dedicated GPUs and that demanding software (including games) often assumes dedicated graphics, with VRAM requirements frequently included.

On many “gaming-ready” laptops, the system may have both integrated and discrete graphics, and performance issues occur if the game runs on the integrated GPU instead of the discrete GPU. Selecting dedicated graphics (for the application or globally, depending on the platform) forces the workload onto the more capable GPU and typically resolves lag. Overclocking RAM is not the first-line fix and adds instability risk, NIC teaming is irrelevant to local rendering performance, and hyperthreading helps some CPU workloads but won’t solve a GPU-bound modern game. Therefore, Select dedicated graphics (C) is best.

The correct answer is C because the representative should first verify what the warranty covers and then handle the customer professionally by reviewing available repair or replacement options. Liquid damage is commonly treated differently from normal product defects. The Mike Meyers/Mark Soper material explains that liquid contact indicators are often used so a carrier or manufacturer can determine whether water damage is covered or refused under warranty. The All-in-One Exam Guide also states that technicians should offer repair or replacement options as needed and allow the customer to decide among valid options. CompTIA’s Core 2 objectives include setting expectations, communicating status, offering repair/replacement options, and providing proper documentation. Therefore, automatically replacing the laptop is not appropriate, but immediately declining or escalating to legal/manufacturer support is premature unless the warranty or store policy requires it.

3G networks generally do not provide the bandwidth required for seamless HD video streaming. With only two signal bars and a 3G connection, the mobile device likely cannot maintain the necessary data throughput, resulting in timeouts or buffering failures. This is a classic symptom of insufficient network speed or signal strength.

A. Lack of Wi-Fi may contribute, but the root cause is the low mobile bandwidth, not the Wi-Fi state.

B. A website subscription lapse would return an account error, not a timeout.

D. Full device storage can affect downloads but not streaming from the internet.

PXE (Preboot Execution Environment) allows workstations to boot over the network and download an OS image from a server. It is ideal for automating mass deployments using baseline images across many machines without the need for physical media.

A. An ISO is a disk image file but requires mounting or physical media.

B. Secure Boot is a security feature, not a method of deploying OS images.

C. USB requires manual installation and is not suitable for automated deployment at scale.

The correct answer is A. Check for malicious applications, because excessive data usage, device overheating, and rapid battery drain are classic indicators of mobile malware or spyware running in the background.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, malicious applications can continuously transmit data, mine cryptocurrency, or monitor user activity, all of which cause increased network usage and battery consumption—even when the device appears idle.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that the first step in mobile troubleshooting is identifying whether unauthorized or malicious apps are present. Reviewing installed applications and running a mobile security scan can quickly confirm the root cause.

The Mike Meyers / Mark Soper Lab Manual explains that disabling networks or enabling airplane mode only masks symptoms temporarily and does not remove malware. Factory resets are effective but should be used after confirming malware or if other remediation steps fail.

Because the symptoms strongly suggest malicious background activity, the most appropriate first action is to check for malicious applications, making A the correct answer.

This scenario describes a rogue access point — a malicious or unauthorized wireless access point that uses the same SSID as the legitimate network. Users may connect to it unknowingly, which can result in limited network access, data interception, or redirection of traffic. The inability to reach internal file servers supports this being an unauthorized AP with no connection to internal resources.

A. A DNS issue would impact name resolution, not connectivity to file servers directly.

B. VLAN issues generally affect segmentation, not mimic SSID problems.

C. An incorrect IP address could cause connectivity issues, but not in the presence of a malicious AP broadcasting the same SSID.

Aclean installensures all malware is eliminated by completely wiping and reinstalling the OS. System restore or repair may leave traces.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“If malware cannot be completely removed, perform a clean installation of the operating system. This ensures no remnants remain on the machine.”

The Local Users and Groups Manager (lusrmgr.msc) is the utility for managing user accounts, including renaming the default Administrator.

From Quentin Docter – Complete Study Guide:

“The lusrmgr.msc snap-in allows renaming and managing local user accounts, including the default administrator.” .

The user’s issue likely stems from amobile data restriction or cap, especially since uploads work on Wi-Fi but not cellular. Checkingdata usage limitswill help determine if mobile uploads are blocked.

FromAll-in-One Exam Guide:

“When data-intensive functions fail on mobile networks but not on Wi-Fi, it’s often due to data caps or metered connection limits.”

FAT32cannot support files larger than 4GB.NTFSsupports large file sizes and is compatible across Windows systems, making it the correct choice for transferring a 4.57GB file.

FromAll-in-One Exam Guide:

“NTFS is the preferred file system for large file transfers within Windows. FAT32 has a 4GB file size limit, which makes it unsuitable for modern use cases involving large files.”

The correct answer is A. Detailed guides for resolving common issues, because effective deployment documentation must support ongoing troubleshooting and support, not just initial installation. Including known issues and resolution steps allows future technicians to resolve problems efficiently and consistently.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, high-quality technical documentation should include error conditions, common failure points, and step-by-step remediation procedures. This information significantly reduces mean time to resolution (MTTR) and improves service quality.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that help desk documentation should evolve over time, incorporating lessons learned from previous incidents. Troubleshooting guides turn deployment documentation into a practical reference rather than a static record.

The Mike Meyers / Mark Soper Lab Manual further clarifies that email logs are informal and unstructured, vendor contact information is supplementary, and end-user manuals are not intended for technical troubleshooting. None of these provide actionable guidance for technicians resolving future issues.

Because the goal is to ensure long-term supportability and effective troubleshooting, the most important inclusion is detailed guides for resolving common issues, making A the correct answer.

1st CLI Resolution

copy " C:\Program Files\Testing\msvcp100.dll " " User-PC02\C$\Windows\System32 " /v /y

2nd CLI Resolution

regsvr32 msvcp100.dll

Why These Are the Correct Choices (Exam Logic)

Why the COPY command is first

The error explicitly states MSVCP100.dll is missing

Other users can run the app → the DLL exists on another system

The fastest, least disruptive fix (preferred by CompTIA) is to:

Copy the known-good DLL into C:\Windows\System32

The /v switch verifies the copy, and /y suppresses prompts — both are enterprise-safe defaults

This restores the missing runtime dependency immediately.

Why REGSVR32 is second

After copying a DLL, Windows may not recognize or properly load it

regsvr32 registers the DLL with the operating system

This ensures:

The Testing application can properly call the runtime library

The fix persists after reboot

This forwards inbound RDP traffic (TCP/3389) from the Internet to the Windows PC, enabling Remote Desktop access.

3. Firewall (screened subnet side)

1. LAN IP: 10.100.0.1

4. Device placement

1. PC: place behind the router (where the port-forward rule points).

2. Game console: place on the Wireless AP (so it can use chat and extra services over WPA2 PSK).

3. Firewall: place in front of the screened subnet (with its 10.100.0.1 IP facing that subnet).

The Windows PC is placed in the screened subnet (behind the firewall) for enhanced security. Remote access to this PC requires port forwarding of TCP port 3389 (RDP), which is correctly configured through the router.

The Game Console is placed on the Wireless AP LAN, using WPA2 PSK for a secure wireless connection. Game consoles typically use peer-to-peer chat and online services that require open access without firewall restrictions, which is why the console is not placed behind the firewall.

CompTIA A+ 220-1102 Reference Points:

Objective 3.4: Given a scenario, implement best practices associated with data and device security.

Objective 2.4: Given a scenario, use appropriate tools to support and configure network settings.

Study Guide Reference: CompTIA A+ Core 2 guides recommend using screened subnets (a type of DMZ) for systems needing controlled external access, such as remote desktops, while placing gaming and media devices on less restricted networks for full functionality.

Ticket #8675310

Issue: Limited network connectivity

Resolution: Refresh DHCP

Verify/Resolve: ipconfig /renew

For the Low priority ticket #8675310 (“A small yellow triangle appeared in the taskbar. I am no longer able to access network resources.”), the Windows yellow triangle on the network icon is the classic indicator of limited connectivity (often caused by a bad/expired DHCP lease, APIPA address, missing default gateway, or DNS info not being assigned).

Correct PBQ Selections (Ticket #8675310)

Issue

Limited network connectivity

Why (CompTIA logic):

That yellow warning triangle means the NIC is connected at Layer 2 (link is up), but the system likely doesn’t have valid Layer 3 config (IP/gateway/DNS), so it can’t reach network resources.

Resolution

Refresh DHCP

Why this is the most efficient fix:

When a Windows PC can’t access network resources and shows “limited connectivity,” the fastest, lowest-risk fix is to renew DHCP so the PC can pull:

a valid IP address

default gateway

DNS servers

This directly resolves the most common root cause behind that icon.

Verify / Resolve

ipconfig /renew

Why this is the correct verification/remediation command:

ipconfig /renew is the direct command to request a fresh DHCP lease. After renewal, the user should regain access to network resources if DHCP was the issue.

What this fixes (what you’d expect to see)

Before the fix, the attachment (Output.txt) in these PBQs typically shows symptoms like:

169.254.x.x (APIPA) → DHCP failed

Missing/blank Default Gateway

DNS not present or incorrect

After ipconfig /renew, you should see a normal private IP (like 192.168.x.x / 10.x.x.x / 172.16-31.x.x) and a valid gateway/DNS.
