CompTIA 220-1202 Dumps

The correct answer is C. Change the User Account Control (UAC) settings , because the credential prompt during installation indicates that the system is requesting administrative privileges . In Windows environments, UAC is designed to prevent unauthorized system changes by prompting for administrator approval when elevated permissions are required.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , UAC acts as a security boundary between standard user activities and system-level changes such as software installation. If a user does not have sufficient privileges, the system will request administrator credentials before proceeding.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that technicians can temporarily adjust UAC settings or provide proper elevation to allow legitimate installations. This is especially common in corporate environments where users operate with standard accounts.

The Mike Meyers / Mark Soper Lab Manual reinforces that restarting the computer or using a different browser does not change permission requirements. Contacting the software vendor is unnecessary when the issue is clearly related to local security controls.

Because the installation is blocked by privilege restrictions enforced by UAC, adjusting User Account Control settings or providing proper elevation is the correct and most efficient resolution, making C the correct answer.

Background applications can significantly drain a smartphone’s battery, even when the device is idle. A technician should first review which apps are running in the background and consuming power through the battery usage section of the OS. Disabling or restricting power-hungry apps often resolves poor battery life.

A. Storage usage doesn’t significantly affect battery life.

B. End of software support is unrelated to battery performance unless it ' s causing inefficient processes, which would still be secondary.

C. Charger wattage affects charging speed, not battery life after charging.

The correct answer is C. In-place upgrades , because this migration method preserves existing user data, applications, and settings while upgrading the operating system to a newer version. Since a large percentage of users store documents locally, maintaining those files during the upgrade is a key requirement.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , an in-place upgrade replaces the operating system files while keeping user profiles, installed applications, and local data intact. This significantly reduces the risk of data loss and minimizes disruption to users.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that clean installs erase the existing OS and require data backup and restoration, which is time-consuming and risky when users store files locally. Zero-touch deployments are automated but typically rely on standardized images and centralized data storage, which does not align with this scenario.

The Mike Meyers / Mark Soper Lab Manual reinforces that in-place upgrades are ideal when preserving user environments is a priority and when systems already meet the requirements for the newer OS.

Because the goal is to upgrade Windows while retaining locally stored documents , in-place upgrades are the most appropriate solution, making C the correct answer.

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.

The symptoms point to malicious or rogue content : frequent “security warning” pop-ups that push “tools” is a classic sign of scam/rogue apps, and the new fast battery drain suggests an unwanted process running in the background. The CompTIA objectives explicitly list mobile security symptoms such as “high number of ads,” “fake security warnings,” and “unexpected application behavior,” which aligns with this scenario. On the browser side, Quentin Docter notes that if you continually receive pop-ups or overlays, “you may be infected with malware,” and recommends scanning with antivirus/antimalware software. He also explains that clearing browsing data/cache is sometimes necessary to resolve browser-related problems and details how to clear cache/browsing data.

Because the user tapped the pop-up and then battery life worsened, the best practical fix is to remove the likely malicious application(s) (uninstall unknown apps) and clear browser cache to eliminate stored site data/scripts fueling the pop-ups. A factory reset is a stronger last resort, but least disruptive remediation is A.

Badge readers are electronic access control systems that require authorized users to scan a badge (e.g., RFID or magnetic strip cards) to gain access to restricted physical locations. These systems typically log all access attempts—successful or denied—providing both detection and recording of access events.

A. Bollards are physical barriers to prevent vehicle access.

B. Video surveillance can record access visually but does not track identity unless integrated with access control systems.

D. A fence restricts access but doesn ' t detect or record who entered.

Domain join capability is a key Windows edition differentiator. In Quentin Docter’s Windows editions comparison, Home explicitly “lacks support for… joining to a domain,” while Pro “can join a Windows server domain.” This applies across Windows 10/11 edition families: Home is positioned for consumers and does not include domain-join features, whereas Pro includes the business feature set.

The All-in-One guide states the same concept: “Windows Home systems cannot become part of a domain; to do that, you’ll need something like Windows Pro.” The Mike Meyers Lab Manual reinforces that Pro is the baseline edition for domain membership in business environments.

Given the answer choices, Windows 11 Pro is the correct selection for joining a domain.

Because this is a government client with confidential data and a strict requirement to follow regulatory compliance , the best practice is to use a certified third-party destruction service that can provide documented proof of destruction. The All-in-One guide explicitly notes that “professional hard drive disposal services are third-party vendors” that guarantee drives are thoroughly destroyed by issuing a certificate of destruction/recycling , which provides assurance that data will not fall into the wrong hands. Mike Meyers’ Lab Manual repeats the same exam point: third-party vendors “will guarantee they have truly, thoroughly destroyed drives by issuing a certificate of destruction/recycling.”

Low-level formatting (often used to mean overwrite/zero-fill) can sanitize drives, but it may not satisfy the requirement for provable compliance and chain-of-custody documentation, especially for regulated environments. Targeted deletion is ineffective because deleted data can remain recoverable. In-house incineration is extreme and may be restricted, unsafe, or noncompliant without proper facilities and documentation. Therefore, Certified third-party destruction (B) is the best option.

The correct answer is D. Roaming profiles , because roaming profiles allow users to log in to any domain-joined workstation and automatically access their personal settings, documents, and configuration without storing data locally on each machine. This is ideal for environments with hot-desking or shared workstations .

According to the Quentin Docter – CompTIA A+ Complete Study Guide , roaming profiles store user data centrally on a server rather than on individual computers. When a user logs in, their profile is loaded; when they log out, changes are saved back to the server. This minimizes data duplication and reduces the risk of data being left behind on shared systems.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that roaming profiles improve security by preventing sensitive user data from being permanently stored on multiple endpoints. This also simplifies backup and recovery, since user data resides in a centralized location.

The Mike Meyers / Mark Soper Lab Manual clarifies that portable drives introduce data loss risks, cloud email only addresses messaging data, and certificate storage does not manage user profiles or documents.

Because the goal is to maintain data security while allowing mobility and minimizing data transfer , roaming profiles are the most appropriate solution, making D the correct answer.

Once a malware incident has been confirmed, the immediate next step is to contain the threat. Quarantining infected systems prevents the malware from spreading to other devices and isolates the malicious code for further analysis or remediation.

B. Educating end users is important but occurs later in the incident response process.

C. Disabling System Restore is part of cleanup, not containment.

D. Updating and scanning should occur after the system is quarantined to prevent further infection or spread.

BitLocker To Go is a Microsoft encryption feature specifically designed for removable drives such as USB flash drives and external hard drives. It allows users to protect the data on these devices by requiring a password to decrypt the contents, thereby preventing unauthorized access in the event the device is lost or stolen.

A is correct because BitLocker To Go is directly tied to password-protecting removable media.

B and C are unrelated to BitLocker To Go; Secure Boot and VPN encryption are entirely different security layers.

D applies to BitLocker (not BitLocker To Go) and full disk encryption on internal drives using TPM.

Shreddingphysically destroys the platters, making data recovery virtually impossible. It ' s more effective and accessible than degaussing or low-level formatting.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Physical destruction methods like shredding are the most secure options for ensuring data on failed drives cannot be recovered.”

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.

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.

When Task Manager repeatedly fails to open, that’s a strong red flag for system tampering—especially malware designed to block diagnostic and remediation tools. Quentin Docter explains that stealth malware attempts to avoid detection by “masking itself from applications” and can redirect commands around itself to avoid detection . That behavior fits the symptom of a core troubleshooting utility (Task Manager) not launching when an administrator needs it.

Docter also reinforces that the correct process in suspected malware cases begins with “ identify and verify the malware symptoms ,” followed by containment and remediation steps. If a key system tool is blocked, that itself is a “verify symptoms” indicator that the system is compromised and needs malware-handling procedures.

The other choices don’t explain the symptom well: a dev app running would not normally prevent Task Manager from launching; Windows Update set to manual wouldn’t block Task Manager; and a moved pagefile might affect performance but not typically stop Task Manager from opening at all. Therefore, malware infection is the most likely cause.

Online collaboration tools (for example, Microsoft 365/OneDrive, Google Workspace/Drive) typically store documents in cloud storage and rely on a sync client to make those files appear locally on each device. If the user can’t see the document on the laptop, the most direct remediation is to synchronize the remote (cloud) folder so the document downloads to the laptop and stays consistent across devices. The All-in-One guide explains that productivity platforms are “designed to be synchronized across multiple devices,” allowing work to be paused on one device and resumed on another, and that many sync problems come down to configuration or a partial sync that leaves data not fully downloaded. It also notes that enabling/adjusting synchronization settings is often the fix. Quentin Docter similarly describes synced files becoming accessible through File Explorer once server/client synchronization is configured and highlights “Documents” as a common sync data type. Mike Meyers reinforces that file services like OneDrive/Google Drive use an installed app on each device to specify what gets synchronized.

For legacy Windows systems, the simplest and most compatible approach is a Windows batch script using built-in commands like net use . Quentin Docter explains that “ Remapping network drives can be done… with VBScript, PowerShell, Window batch scripts… However, Windows batch script and PowerShell are the most common ,” and shows the batch method using net use m: \\server1\files . Because the scenario specifies legacy equipment and simple Windows commands , batch scripting is the best fit: it runs directly under cmd.exe without needing additional runtimes or frameworks that may be missing or unsupported on an end-of-life OS.

Mike Meyers’ Lab Manual reinforces that “ The net use command is a command-line method for mapping network shares ,” giving the example net use x: \\server1\research . The All-in-One guide provides the same exact mapping approach and emphasizes that net use maps a drive letter to a UNC path.

Therefore, the best script type here is Batch (B) .

Device encryptionensures that even if someone bypasses biometrics or has physical access to the phone, they cannot read the stored data without the encryption key.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Encryption is the most effective way to protect data at rest. Even if the device is lost or stolen, encryption ensures the data remains inaccessible without the correct key or passcode.”

3-D rendering is a graphics-intensive workload, and minimum hardware checks for this type of software commonly fail due to GPU capability (including dedicated vs. integrated GPU support) and VRAM requirements. Quentin Docter explains that application “Display” requirements can include “ a graphics processing unit (GPU). A specific GPU may be required if the application will process video or graphics .” He also notes that “ VRAM requirements are typically related to applications that are graphic intensive, such as gaming ,” which aligns strongly with 3-D rendering workloads.

Mike Meyers’ Lab Manual reinforces that “ graphically demanding applications… state specific graphics requirements ,” and that CompTIA focuses on “ dedicated graphics cards versus integrated ones ,” because integrated GPUs are often less capable for demanding graphics tasks. It also reminds that systems with integrated GPUs share RAM with graphics, which can matter when software checks VRAM.

Therefore, the first thing to verify is GPU requirements (B) , not USB/NIC/PSU.

Many modern commercial software applications (including photo editors like Adobe Photoshop) offer tiered features based on user subscriptions or license levels. If certain features are locked and prompt for a login, the issue is likely due to a missing or unassigned software license. Assigning the correct license through a centralized license management system (such as Adobe Admin Console or Microsoft 365 portal) will enable those features.

B. VPN connection does not affect local software licensing.

C. Repairing the application does not resolve license entitlement.

D. Reinstalling the software won’t help unless the license is assigned.

When a technician exhausts all troubleshooting steps within their knowledge and the issue remains unresolved, the best practice is to escalate the issue to a higher-level technician or team. Additionally, the technician should clearly communicate the next steps to the customer to maintain transparency and reduce frustration. This ensures continuity of support and upholds customer satisfaction.

B. Dismissing the customer is unprofessional and violates proper customer service protocols.

C. Interrupting the customer and providing excuses escalates the tension and is inappropriate.

D. Continuing to ask questions without new troubleshooting steps wastes time and increases frustration.

To allow Remote Desktop Protocol (RDP) access, the firewall must be configured to allow inbound connections on TCP port 3389. If the Windows Firewall blocks RDP, users will not be able to connect remotely even if the feature is enabled in system settings.

B. Computer Management allows configuration of services and local users, but not network access.

C. User Accounts is for account setup and control, but enabling remote access requires firewall configuration.

D. Ease of Access is unrelated to remote connectivity—it’s for accessibility features.

Because the employee needs graphical interface (GUI) access to Linux servers, the best option is VNC (Virtual Network Computing) . VNC is specifically designed for remote control and sharing of desktops , meaning it can present the full graphical desktop of the Linux server to the remote user and allow interaction as if they were sitting at the machine. Quentin Docter describes VNC as “a remote control tool for the sharing of desktops,” typically using TCP port 5900, and notes it is similar to RDP but is an open-source protocol; it can support encryption via plug-ins (important for secure remote use). Mike Meyers’ Lab Manual reinforces the key distinction: SSH provides command-line access , but “when you need remote access to the full graphical desktop, you need a remote desktop application,” and many of those use VNC (or RDP).

By contrast, SSH and Telnet are primarily text-console tools (Telnet is also unencrypted/insecure), and WinRM is Windows-focused remote management rather than the standard way to provide GUI access to Linux desktops.

The correct answer is C. The default gateway is not set , and this is clearly indicated by the ipconfig output showing the Default Gateway: 0.0.0.0 . In TCP/IP networking, the default gateway is the router address that allows a workstation to communicate with networks outside its local subnet , including the internet. Without a valid default gateway, a device can only communicate with other devices on the same local network.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , a missing or incorrect default gateway is one of the most common causes of a system being unable to access external resources. The guide explains that when a destination IP address is outside the local subnet, the workstation forwards the traffic to the default gateway. If no gateway is defined, the traffic has nowhere to go and is dropped.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide reinforces that an IP address such as 10.203.10.22 with a subnet mask of 255.255.255.0 is valid for internal communication. The DNS suffix comptia.org is also not responsible for routing failures. DNS resolves names to IP addresses, but routing still requires a gateway.

The Mike Meyers / Mark Soper Lab Manual further clarifies that a subnet mask error would prevent even local communication, which is not indicated here. Because only external websites are unreachable, the absence of a default gateway is the definitive root cause.

AVPN (Virtual Private Network)creates a secure tunnel between the clerk’s home device and the town server, ensuring private and authenticated access.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“VPNs are essential for remote access to internal resources, providing secure connections over public networks.”

The correct answer is C. Browser policy , because the listed requirements apply specifically to browser-level behavior and settings , not general network traffic or system-wide configuration. Browser policies allow administrators to centrally control how browsers behave on managed systems.

The Quentin Docter – CompTIA A+ Complete Study Guide explains that modern browsers support administrative templates or policies that govern password storage, trusted sites, security levels, history handling, and URL restrictions. These policies ensure consistent behavior across all user systems without relying on manual configuration.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide clarifies that while Group Policy can deploy browser policies, the object being configured is still the browser itself. The question asks what is best to configure , not how it is delivered. Browser policies directly control password management, trusted URLs, and security zones.

The Mike Meyers / Mark Soper Lab Manual further notes that web proxies and gateways filter traffic at the network level and cannot control local browser features such as password storage or history retention.

Because every listed requirement is a browser-specific control , the most accurate and targeted solution is Browser policy , making C the correct answer.

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 correct answer is D. Smishing , which is a form of phishing attack conducted via SMS text messages . The key indicators in this scenario are the unexpected text message and the embedded link prompting the user to reset a password. These attacks rely on urgency and fear to trick users into clicking malicious links or providing credentials.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , smishing attacks often impersonate legitimate organizations such as banks, IT departments, or service providers. The attacker claims that an account action is required, such as resetting an expired password, to prompt immediate user response.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that smishing is distinct from other phishing variants based on delivery method . Vishing uses voice calls, spear phishing targets specific individuals via email, and whaling targets high-level executives. Since this attack is delivered via text message , it is classified as smishing.

The Mike Meyers / Mark Soper Lab Manual reinforces that modern attackers increasingly use SMS because users often trust text messages more than emails. This makes smishing a highly effective and common attack vector.

Because the attack uses SMS with a malicious link, smishing 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.

Image deployment is the fastest and most efficient method for installing operating systems on multiple machines. It involves creating a pre-configured image of an OS and deploying it across systems using tools like Windows Deployment Services (WDS) or third-party imaging solutions. This method saves time and ensures consistency across all devices.

A. Physical media is slow and not scalable.

B. Mountable ISOs are useful but still require manual installation.

C. Manual installation is time-consuming and not suitable for large-scale deployment.

Comprehensive and Detailed Explanation From Exact Extract:

When an OS reaches its end of life (EOL), it no longer receives updates or support, including critical security patches.

From the Quentin Docter Study Guide:

“End-of-life means the manufacturer no longer supports the OS with updates or security patches, which exposes systems to vulnerabilities unless upgraded”.

All-in-One Exam Guide adds:

“End-of-life notifications serve as a final warning that continued use of the OS will be insecure and unsupported. It’s crucial for administrators to plan migration”.

TheServicestool in Windows allows a technician to view service dependencies and status. If the print spooler can ' t start due to a dependency, Services is the correct tool to inspect and manage them.

FromAll-in-One Exam Guide:

“The Services console allows technicians to view, start, and configure system services, including setting recovery actions and viewing dependencies.”

The correct answer is B. The SATA HDD power cable is disconnected , because RAM upgrades require opening the case, which can easily result in accidentally loosening or disconnecting internal cables. If the system cannot detect the boot drive, it will display a “No boot device found” error.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , one of the first troubleshooting steps after hardware changes is to verify that all internal cables—especially SATA data and power cables—are securely connected. A disconnected drive will not be detected by the BIOS or UEFI firmware.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that boot order changes are less likely unless the technician explicitly modified BIOS settings. Similarly, reformatting a drive would not occur during a RAM upgrade.

The Mike Meyers / Mark Soper Lab Manual reinforces that physical connection issues are among the most common causes of boot failures following hardware maintenance. A disconnected power cable prevents the hard drive from spinning up, making it invisible to the system.

Because the issue appeared immediately after opening the case for a RAM upgrade, the most likely cause is a disconnected SATA power cable , making B the correct answer.

The most likely reason a legacy tablet cannot run the latest version of an app is that the tablet’s operating system is end-of-life (EOL) or otherwise too old to meet the app’s supported OS/version requirements. Quentin Docter explains that an OS life cycle ends when it is no longer supported, and that an OS at end-of-life will no longer receive updates (including feature updates), making it increasingly incompatible with modern software that expects newer OS frameworks and APIs. The All-in-One guide reinforces this by noting that apps may fail to launch or install when they are not compatible with the device’s OS version (or related vendor customizations).

While insufficient storage can also prevent an update, that typically produces an “update failed/not enough space” condition rather than a consistent inability to use the latest version due to platform support; Mike Meyers’ Lab Manual specifically calls out free space as a common cause of update failures. MDM restrictions and malware are possible but are less “most likely” for a personal legacy tablet.

The correct answer is B. Kerberos token , because Kerberos authentication relies heavily on precise system time synchronization between clients, servers, and the Key Distribution Center (KDC). Kerberos uses time-stamped tickets to prevent replay attacks, and even small time discrepancies can cause authentication failures.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , Kerberos requires clocks on all participating systems to be synchronized within a narrow tolerance (typically five minutes). If system time is inaccurate, Kerberos will reject authentication requests, resulting in login failures and access denial.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that Kerberos tokens include timestamps to ensure tickets are valid only for a short time window. This security design protects against attackers reusing captured authentication data.

The Mike Meyers / Mark Soper Lab Manual reinforces that time synchronization issues are a common cause of Kerberos-related login problems in domain environments. Services like TACACS+, RADIUS, and WPA do not depend on strict system time synchronization in the same way Kerberos does.

Because Kerberos authentication cannot function correctly without accurate system time , B is the correct answer.

A “utility failure” means the building’s AC power source has dropped out (blackout) or sagged severely, causing the workstation to lose power instantly and shut down. The best way to prevent an immediate shutdown during these events is an Uninterruptible Power Supply (UPS), which contains a battery and can continue supplying AC power long enough to keep the PC running briefly and allow a graceful shutdown. Mike Meyers’ Lab Manual states that a UPS “continues to supply AC power…during both brownouts and blackouts via a battery,” preventing the computer from instantly losing power when the utility fails. Quentin Docter likewise explains that UPS devices protect against “power sags and even power outages,” using stored battery energy so the administrator (or OS integration) can safely shut down rather than crash off.

A surge suppressor protects from spikes, not outages. A redundant PSU only helps if the PSU fails, and Docter notes it cannot keep a system running during a power outage. A line voltage regulator helps stabilize voltage but doesn’t provide power when utility power is absent.

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.

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.

First Chat Response:When the user mentions setting up a new router, the best initial response to maintain a helpful and professional tone is:

> Select reply: " I am happy to assist you today. "

Second Chat Response:When the user states that they need to set up basic security settings:

> Select reply: " Is this the first router in your office? "

Third Chat Response:After learning it ' s a replacement router and the user is logged into the router ' s web page:

> Select reply: " The first thing you need to do is change the default password. "

Fourth Chat Response:For the response about password settings:

> Select reply: " Create a new password with an uppercase, a lowercase, and a special character. "

Fifth Chat Response:When the router prompts to reboot:

> Select reply: " Yes, reboot please. "

Study Guide Reference: The CompTIA A+ Core 2 guide highlights the importance of changing default credentials and using strong password policies, particularly in SOHO environments where routers are often targeted.

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.

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.

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
