220-1202 CompTIA A+ Core 2 2025 Exam Questions and Answers

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.

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 first step the CFO should take is to verify the VPN status . When working remotely, access to internal resources such as databases, file servers, and accounting systems typically requires a secure Virtual Private Network (VPN) connection. Without an active VPN tunnel, the application cannot reach internal database servers, resulting in connection errors.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , database connectivity issues during remote work are most commonly caused by missing or disconnected VPN sessions. Internal applications are often restricted to private IP ranges that are inaccessible over the public internet.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide highlights that VPNs are designed to extend the corporate network securely to remote users. If the VPN is disconnected, authentication to internal services will fail even if the application itself launches correctly.

The Mike Meyers / Mark Soper Lab Manual further explains that restarting the PC or updating the application does not resolve network-path issues. Returning to the office is unnecessary if secure remote access is functioning as designed.

Because the error specifically indicates an inability to connect to a database—and not a corrupted application—the most logical and efficient first troubleshooting step is to confirm that the VPN is connected and authenticated .

The completed configuration:

1. Wireless AP (LAN side)

1. LAN IP: 192.168.10.1

2. Encryption: WPA2 PSK

2. Router (port-forward rule)

1. Allow TCP Any 3389

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.

MDM hardening often includes enforcing stronger authentication on mobile devices. The phrase “unique to each user” points to something inherent to the individual— biometrics —rather than something the user knows (password/pattern) or something they have (PIV/smart card). Quentin Docter explains: “ Biometric devices use physical characteristics to identify the user. This type of authentication is considered something that you are ,” and lists common implementations including “ fingerprint… scanners .” This exactly matches a fingerprint, which is unique per person and commonly enforced via device policies in MDM environments.

Docter also notes mobile devices increasingly implement biometrics for access control, specifically citing “ fingerprint access control ” adopted by manufacturers. A drawn pattern and a password are knowledge factors and can be shared/observed, while a PIV card is a possession factor (something you have) and can be lost or loaned. Because the question specifies a hardening technique “unique to each user,” the best match is the biometric factor: fingerprint (B) .

A low-cost home lab for practicing server management and scripting strongly points to Linux because it is widely available at no cost and is designed to support many server-style workloads. The All-in-One guide states plainly: “ Linux is a popular, free, open source operating system ,” and notes that there are many distributions (distros), giving flexibility for different needs. Quentin Docter adds key context about Linux’s purpose: Linus Torvalds created it as “ a completely open source operating system for the world to use… completely free for anyone to use ,” and highlights that many Linux distributions exist today.

From a cost standpoint, Docter’s licensing section defines open source as “ not only… free, but the source code… is also shared ,” and explicitly lists “ OSs such as Linux ” as open source examples. This directly supports “low-cost.”

Finally, Linux is a common target environment for real server administration and scripting practice (shell tools, package repositories, services), making it the best match versus ChromeOS/macOS/Windows for this lab goal.

The correct answer is D. Enabling HTTPS-Only Mode , because HTTPS ensures that all communication between the browser and websites is encrypted using TLS (Transport Layer Security) . This protects sensitive information such as usernames, passwords, and payment details from interception.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , HTTPS encrypts data in transit, preventing attackers from eavesdropping or modifying communications. HTTPS-only modes in modern browsers block or warn users when a site does not support secure connections.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that HTTPS is essential for protecting authentication credentials and financial information, especially on public or untrusted networks. Enforcing HTTPS-only connections ensures users cannot accidentally submit data over unencrypted HTTP.

The Mike Meyers / Mark Soper Lab Manual clarifies that disabling cookies or JavaScript may break website functionality but does not guarantee encryption. Pop-up blockers address nuisance behavior, not data security.

Because the objective is to encrypt browser communications and protect sensitive data , enabling HTTPS-Only Mode is the most effective and direct solution, making D the correct answer.

The scenario strongly suggests the device has been compromised by malware delivered through a social-engineering message (an “unexpected overdue invoice” attachment). After the attempt, the phone shows system-wide performance issues affecting the browser and other apps, and a restart does not fix it—this matches common mobile malware symptoms such as sluggish response time and abnormal behavior that persists across reboots. When symptoms persist beyond a soft reset, the most reliable remediation is to return the device to a known-good state by performing a factory reset (wipe). Quentin Docter explains that a factory reset is much more effective and will remove malware along with applications, and that when a security symptom indicates malware, the device should be factory reset and then protected with antimalware before reinstalling apps.The All-in-One guide similarly teaches an escalation path: stop/uninstall suspect apps, and if these steps don’t resolve the behavior, use a factory reset to cleanse the device. 【 turn27file4†L9-L14 】 Mike Meyers’ Lab Manual also lists factory resets among the key tools for resolving persistent mobile app security issues.

SSH (Secure Shell) allows encrypted console sessions to access and administer remote servers.

From Quentin Docter – Complete Study Guide :

“Secure Shell (SSH) provides an encrypted console session to manage Linux, UNIX, or network devices securely over TCP port 22.” .

The correct answer is C. BAT , because batch files are specifically designed to execute a sequence of commands automatically in Windows environments. They are commonly used for startup tasks such as launching applications, mapping network drives, setting environment variables, or running maintenance scripts.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , batch files (.bat) are text-based scripts interpreted by the Windows Command Processor (cmd.exe). They are lightweight, easy to create, and can be placed directly in startup folders or scheduled through system tasks.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that batch files are ideal for automation because they do not require compilation and can run without user interaction. This makes them well-suited for startup operations that must execute consistently every time the system boots or a user logs in.

The Mike Meyers / Mark Soper Lab Manual contrasts batch files with other file types: .sh files are used in Linux and macOS, .msi files are installer packages, and .exe files are compiled programs that may prompt user interaction or security warnings.

Because batch files are native to Windows , scriptable, and commonly used for startup automation, C. BAT is the correct answer.

If internal resources (such as intranet or internal apps) can ' t be accessed but external sites work, this often points to aDNS issue, where the system isn ' t resolving internal domain names correctly.

FromAll-in-One Exam Guide:

“When internet access is functional but internal sites fail to load, the issue usually lies with DNS resolution. Internal resources often require internal DNS servers, which may not be configured correctly.”

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.”

Comprehensive and Detailed Explanation From Exact Extract:

If the system fails to boot after removing the USB installation media, it often means the BIOS is not pointing to the correct boot device. This typically involves an issue with the BIOS settings—such as UEFI being disabled when the OS was installed in UEFI mode.

FromAll-in-One Exam Guideby Travis Everett:

“One of the most common post-installation issues is failing to configure the boot mode correctly in BIOS. If an OS is installed in UEFI mode, the UEFI boot must be enabled, otherwise the system won’t detect the bootloader.”

Comprehensive and Detailed Explanation From Exact Extract:

The issue described—“domain cannot be found” despite the ability to ping the server and access the internet—indicates aDNS resolution problem, not a network connectivity issue. The workstation is currently usingpublic DNS servers (8.8.8.8 and 1.1.1.1)whichcannot resolve internal domain names, such as the ones used in Active Directory environments. To resolve this, the technician needs tochange the DNS settings to point to the internal DNS server, which in most domain setups is thedomain controller itself (likely 192.168.1.10 in this case).

Here’s the breakdown of the incorrect options:

B. Assign a static IP address: The IP is already assigned and functioning; the device can ping and reach the network and internet.

C. Configure a subnet mask: The subnet mask is appropriate for the network range (Class C /24).

D. Update the default gateway: The gateway is valid and allows internet access; this is not the issue.

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 must know how to troubleshoot OS-based network configurations, includingproper DNS settings in domain environments.

The correct answer is A. .app , because macOS applications packaged as .app files are typically self-contained application bundles . This means that all required application files are stored within a single directory that appears as one file in Finder. When the .app file is moved to the Trash, the application is effectively removed from the system.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , macOS applications are commonly distributed as .app bundles, allowing for simple installation and removal. This design contrasts with Windows, where applications often install files across multiple directories and require uninstallers.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that dragging a .app file to the Trash is generally sufficient to uninstall the software, although some applications may leave behind preference files or caches. However, from an exam perspective, .app is the only option that supports this uninstall behavior.

The Mike Meyers / Mark Soper Lab Manual further clarifies that .msi and .exe are Windows formats, .rpm is used by Linux package managers, and .pkg installers often install system-wide components that require a formal uninstallation process.

Because .app files support simple drag-to-trash uninstallation , A is the correct answer.

The correct answer is C. net use , which is the Windows command-line utility used to display, create, and remove mapped network drives and SMB (Server Message Block) connections . When working remotely through command-line interfaces, technicians often rely on net use to quickly verify which network shares are currently connected.

The Quentin Docter – CompTIA A+ Complete Study Guide explains that SMB is the protocol Windows uses for file and printer sharing, and mapped drives are maintained through SMB sessions. The net use command lists all active connections, including the drive letter, remote UNC path, and connection status.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide highlights that net use is especially valuable for remote troubleshooting because it does not require a graphical interface. This makes it ideal when administering multiple systems via command prompt or remote shell.

The Mike Meyers / Mark Soper Lab Manual clarifies that systeminfo displays OS and hardware details, hostname only shows the system name, and nslookup is used for DNS queries. None of those commands provide information about mapped SMB shares.

Since the task is to verify existing SMB mappings , net use is the only command that directly fulfills this requirement, making C the correct answer.

Comprehensive and Detailed Explanation From Exact Extract:

A .bat file (batch file) is a script file in DOS, OS/2, and Microsoft Windows. It contains a series of commands that are executed by the command-line interpreter. In Windows environments, batch files are commonly used to automate log-in tasks, such as mapping network drives, launching applications, or setting environment variables during the user ' s logon process.

B. .sh is a shell script used in Linux/Unix environments.

C. .py is a Python script, which can be used for automation but is not commonly run directly at user logon in standard Windows environments.

D. .js is JavaScript, used mainly in web development and not for system-level scripting in Windows logon automation.

This is part of the user education step after a security incident to prevent future occurrences.

From Quentin Docter – Complete Study Guide :

“User education and awareness is a crucial part of preventing phishing attacks. After an incident, it is vital to train users on recognizing suspicious messages.” .

Comprehensive and Detailed Explanation From Exact Extract:

The net use command in Windows is used to map (assign) a shared drive from the command line. The syntax typically looks like: net use X: \server\share where X is the drive letter and \server\share is the network path.

A. pathping tests network latency and packet loss.

B. nslookup is used for DNS troubleshooting.

D. tracert shows the route packets take to reach a destination — not for drive mapping.

FromAll-in-One Exam Guide:

“Windows Hello offers a range of biometric and PIN-based login methods designed to simplify access while enhancing security.”

“It can be used in place of a password, ideal for users who frequently forget credentials.”

Comprehensive and Detailed Explanation From Exact Extract:

Ransomware is a type of malware that encrypts the user ' s files and demands a payment (ransom) for the decryption key. When a user receives a message stating that their files are encrypted and cannot be accessed, ransomware is the most likely cause. The attacker’s goal is to hold the data hostage until the victim pays to restore access.

A. Keylogger records keystrokes and doesn’t encrypt files.

C. Phishing is a social engineering tactic to gather credentials, not to encrypt data.

D. Cryptominer uses system resources to mine cryptocurrency, not encrypt files.

Virtualizationallows the legacy OS to be run in a virtual machine (VM) on top of the newer OS. This method provides backward compatibility without requiring outdated operating systems on physical hardware.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Using virtualization is a preferred method when legacy applications are needed after migrating to newer operating systems. It allows legacy environments to exist securely within a modern OS framework.”

The correct answer is D. Chain of custody process , because chain of custody ensures that evidence collected during an incident response is tracked, preserved, and legally defensible . It documents who collected the evidence, when it was collected, how it was stored, and who accessed it throughout the investigation.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , chain of custody is essential when evidence may be used in disciplinary actions, audits, or legal proceedings. Any gap in documentation can render evidence inadmissible.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that chain of custody provides accountability and prevents claims of evidence tampering. Each transfer of evidence must be logged and verified.

The Mike Meyers / Mark Soper Lab Manual clarifies that while order of volatility determines the sequence of data collection, it does not track ownership or handling. Data integrity best practices ensure evidence is not altered, but they do not provide a record of custody.

Because the question focuses on handling and accountability , the required process is chain of custody , making D the correct answer.

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.

“No OS found” commonly indicates the firmware can’t locate boot instructions for the installed OS. If the drive isn’t obviously failing (no unusual noises) and BIOS/UEFI settings are reasonable, a classic cause is a corrupt Master Boot Record (MBR) (on MBR-partitioned disks). Mike Meyers’ Lab Manual explains that when BIOS can’t find an OS, causes may include configuration issues or drive problems, but also states: “If the correct drive is already first in the boot sequence, the master boot record… may be corrupt and need to be rebuilt.”

The Lab Manual also explains what the MBR does: the first sector contains boot code that informs the system about installed operating systems, and “without this bit of code, your OS will never load.” The All-in-One guide describes the same: BIOS looks at the first sector for instructions, and without the MBR code, the OS won’t load.

NTFS corruption wouldn’t typically present as “no OS found” at the firmware stage, and TPM issues usually create different security/boot errors. Therefore, MBR (D) is most likely.

The su (substitute user) command is used in Linux to switch to another user account, most commonly to escalate privileges by switching to the root (administrator) account. It allows administrative tasks to be performed in a terminal session.

A. runas is a Windows command for executing a program under another user ' s context.

B. cmcl is not a valid Linux or administrative command.

C. net user is a Windows command for managing local user accounts.

Comprehensive and Detailed Explanation From Exact Extract:

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.

Comprehensive and Detailed Explanation From Exact Extract:

Multifactor authentication (MFA) is considered one of the most effective security measures for cloud environments. It requires users to verify their identity using two or more factors (e.g., password + phone app code), making it significantly harder for external attackers to gain access, even if the primary password is compromised.

B. Encryption is important for data protection but doesn’t prevent unauthorized logins.

C. Backups protect against data loss but don’t stop breaches.

D. Strong passwords are helpful but can still be phished or cracked — MFA adds a critical extra layer.

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.

To prevent unauthorized physical access to a mobile device, the company must ensure the device locks quickly and requires an authentication factor before anyone can use it. PIN authentication directly blocks access by requiring a passcode to unlock the device—Quentin Docter lists PIN lock as one of the primary “screen lock” methods used to secure mobile devices, explaining it as the most common unlock method (typically 4–6 digits, sometimes alphanumeric).

Screen timeout (auto-lock) reduces the window in which an unattended phone remains usable; the All-in-One guide notes that systems can be set to an automatic timeout and screen lock, requiring credentials after a short period of inactivity. Mike Meyers’ Lab Manual reinforces that you should “protect your data from access by putting a good screen lock on the device,” and that these locks commonly require a password/PIN/pattern/biometric to regain access after locking.

Hotspots, VPN, antivirus, and location services are valuable, but they do not primarily stop someone holding the device from opening it and accessing data.

Issue: Limited network connectivity

Resolution: Refresh DHCP

Verify/Resolve: ipconfig

Issue (drop-down)

Limited network connectivity

Why this matches:

“Internet Down” most commonly indicates the workstation has lost valid Layer 3 connectivity (bad/expired DHCP lease, APIPA address, wrong gateway, etc.). In CompTIA A+ terms, this aligns best with limited connectivity symptoms (can’t reach internet resources).

Resolution (drop-down)

Refresh DHCP

Why this is the most efficient fix:

If the client has:

an expired lease

an APIPA address (169.254.x.x) because DHCP failed

an incorrect IP/gateway from a bad lease

…then the fastest first remediation is to renew DHCP to obtain a correct IP address, default gateway, and DNS servers. This is a standard CompTIA A+ troubleshooting action (quick, low-risk, high-success).

Verify/Resolve (drop-down)

ipconfig

Why this is the correct verification tool:

ipconfig is the primary Windows CLI tool to:

check current IP settings (ipconfig /all)

release/renew DHCP (ipconfig /release and ipconfig /renew)

confirm you received a valid IP + gateway + DNS , which is required for internet access.

What you would do (mapped to those choices)

Using ipconfig to complete “Refresh DHCP” and confirm the fix:

Check current addressing

ipconfig /all

Look for:

Valid IPv4 (not 169.254.x.x )

Valid Default Gateway

DNS servers present

Refresh the DHCP lease

ipconfig /release

ipconfig /renew

Verify outcome

Run ipconfig again to confirm:

You now have a correct IP for the network

Default gateway is populated

If the gateway/DNS populate correctly, internet access typically returns.

When DHCP isn’t enabled, static IPs must be assigned manually, so the engineering team provides the IP details.

From Travis Everett – All-in-One Exam Guide :

“If DHCP is unavailable, technicians need the static IP configuration to connect devices to the network.” .

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.

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
