220-1101 Question 1

Single answer1.1 Given a scenario, monitor mobile device hardware and use appropriate replacement techniques.

A user drops a smartphone, and the display glass is cracked. The image still appears normally, and the touch functionality works across the entire screen. The manufacturer’s service manual for this model states that the front glass is fused to the digitizer and OLED panel as a single factory-sealed assembly. The company wants the most reliable repair with the lowest risk of damaging the phone further. What should the technician do?

  1. A

    Replace only the outer glass using a heat gun and adhesive strips

  2. B

    Replace the complete display assembly according to the manufacturer’s procedure

  3. C

    Recalibrate the digitizer and apply a screen protector over the crack

  4. D

    Replace the battery first, because impact damage commonly causes display cracks

Show answer and explanation

Correct answer: B

Explanation

This question tests mobile device hardware replacement techniques under A+ Core 1 objective 1.1. In real service work, technicians should follow the manufacturer’s documentation for device disassembly and part replacement. On many modern smartphones, the cover glass, digitizer, and display panel are laminated or sold as one service part. In those cases, replacing the entire display assembly is the recommended and most reliable repair, especially when the organization wants to avoid additional damage. Best practices also include using the vendor’s service manual, approved tools, ESD precautions, proper adhesive/seal replacement, and post-repair functional checks such as display quality, touch response, and front-facing sensor/camera alignment.

  • A. Incorrect.

    Incorrect. Although third-party glass-only repairs exist for some phones, this option conflicts with the scenario because the manufacturer specifies that the glass, digitizer, and OLED are fused into one assembly. Attempting to separate laminated layers increases the chance of damaging the OLED, touch layer, frame, or seals. This is not the most reliable or lowest-risk repair.

  • B. Correct.

    Correct. When the manufacturer documents the screen components as a single sealed assembly, best practice is to replace the entire display assembly using the approved procedure. This matches the scenario’s requirement for the most reliable repair and minimizes the risk of additional damage to the display, touch layer, and device sealing components.

  • C. Incorrect.

    Incorrect. Recalibration does not fix physically cracked glass, and a screen protector is only cosmetic mitigation, not a hardware repair. Since the phone has physical damage and the company wants a proper replacement technique, this does not address the failed component.

  • D. Incorrect.

    Incorrect. A battery replacement is unrelated to a cracked front glass/display assembly unless there are separate symptoms indicating battery failure. This distractor reflects a common mistake of replacing unrelated parts after a drop instead of diagnosing the specific damaged assembly.

220-1101 Question 2

Single answerBattery

A technician is troubleshooting a 3-year-old business laptop that shuts down unexpectedly when it is unplugged, even though Windows reports the battery is at 40% charge. The laptop runs normally when connected to AC power. The user needs a reliable fix before traveling. Which action should the technician take FIRST?

  1. A

    Replace the laptop battery with a manufacturer-approved battery

  2. B

    Update the laptop's video driver to reduce power consumption

  3. C

    Disable sleep and hibernation settings in the operating system

  4. D

    Perform a full system recovery to rule out software corruption

Show answer and explanation

Correct answer: A

Explanation

This scenario tests practical battery troubleshooting. In real-world support, unexpected shutdowns at a nonzero charge percentage often indicate a worn or failing lithium-ion battery whose reported capacity no longer matches its actual ability to deliver power. On the A+ Core 1 exam, candidates should recognize when a symptom points to battery replacement rather than unnecessary software troubleshooting. Best practice is to replace the battery with an OEM or manufacturer-approved equivalent to ensure proper fit, charging behavior, and safety. This aligns with common vendor service guidance from major laptop manufacturers, which recommends battery replacement when runtime is inaccurate, the battery cannot hold charge, or the system powers off when unplugged despite reported remaining capacity.

  • A. Correct.

    Correct. A laptop that powers off unexpectedly when disconnected from AC despite showing remaining charge is a classic sign of a failing battery that can no longer provide stable output under load. Given the age of the laptop and the symptom pattern, the most appropriate first action is to replace the battery with a manufacturer-approved unit. CompTIA A+ expects technicians to recognize degraded battery health as a common hardware issue and to use supported replacement parts for safety and compatibility.

  • B. Incorrect.

    Incorrect. Although power management and drivers can affect battery life, a video driver issue would not typically cause an immediate shutdown at a reported 40% charge only when AC power is removed. This option reflects a common misconception that any battery-related symptom must be caused by software optimization rather than battery failure.

  • C. Incorrect.

    Incorrect. Sleep and hibernation settings control low-power behavior, but they do not cause the system to lose power suddenly when the battery is unable to sustain the laptop. Someone might choose this if they confuse an unexpected shutdown with an incorrect power-plan event, but the system's dependence on AC power points to a hardware battery problem.

  • D. Incorrect.

    Incorrect. A full system recovery is too invasive and not an appropriate first troubleshooting step for symptoms that strongly indicate battery degradation. While software corruption can cause instability, it would not normally make the laptop shut off specifically when external power is removed while it otherwise operates normally on AC.

220-1101 Question 3

Single answerKeyboard/keys

A user reports that their laptop suddenly types numbers when they press certain letter keys. For example, pressing U, I, and O enters 4, 5, and 6 instead of letters. An external USB keyboard works normally. You need to restore normal typing on the built-in keyboard as quickly as possible without replacing hardware. What should you do FIRST?

  1. A

    Disable Sticky Keys in Accessibility settings

  2. B

    Turn off Num Lock on the laptop's embedded keypad

  3. C

    Reinstall the keyboard driver in Device Manager

  4. D

    Replace the built-in keyboard assembly

Show answer and explanation

Correct answer: B

Explanation

This scenario reflects a common real-world laptop support issue: the embedded numeric keypad has been enabled. On many compact laptop keyboards, certain letter keys double as number pad keys, and enabling Num Lock changes their output. CompTIA A+ Core 1 expects technicians to recognize common keyboard/key behavior issues and apply the least invasive, most efficient fix first. Standard troubleshooting best practice is to verify keyboard lock states and function-key toggles before moving to drivers or hardware replacement. Manufacturer documentation for laptop models often identifies the exact Fn+key combination used to toggle the embedded keypad or Num Lock.

  • A. Incorrect.

    Incorrect. Sticky Keys affects modifier key behavior such as Shift, Ctrl, Alt, and Windows key combinations. It does not cause letter keys like U, I, and O to produce numbers. This is a plausible distractor because accessibility settings can affect keyboard behavior, but not in this specific way.

  • B. Correct.

    Correct. Many laptops use an embedded numeric keypad that shares keys with part of the letter area, commonly including U, I, O, J, K, L, and M. When Num Lock is enabled, those keys can enter numbers instead of letters. The fastest first step is to toggle Num Lock, often using a dedicated Num Lock key or an Fn key combination.

  • C. Incorrect.

    Incorrect. A driver issue is less likely because the symptom is specific and consistent with an enabled embedded numeric keypad, and the external USB keyboard works normally. Reinstalling the driver is a more time-consuming troubleshooting step and not the best first action.

  • D. Incorrect.

    Incorrect. Hardware replacement is premature. The symptom strongly suggests a keyboard mode setting rather than physical key failure, especially since multiple related keys are affected in a predictable pattern. Best practice is to rule out simple configuration issues before replacing components.

220-1101 Question 4

Single answerRandom-access memory (RAM)

A technician is upgrading a small office desktop that currently has one 8 GB DDR4-2666 DIMM installed in slot A2. The motherboard supports dual-channel memory and has four DIMM slots labeled A1, A2, B1, and B2. The user reports slow performance when many browser tabs and spreadsheets are open. The technician wants to improve performance without replacing the existing module. Which action is the BEST choice?

  1. A

    Install a second 8 GB DDR4-2666 DIMM of matching specifications in slot B2

  2. B

    Install a 16 GB DDR3 DIMM in slot B2 so the system has more total memory

  3. C

    Move the existing 8 GB DIMM from A2 to A1 and leave the other slots empty

  4. D

    Install a second 8 GB DDR4-3200 DIMM in slot A1 to maximize memory speed

Show answer and explanation

Correct answer: A

Explanation

The best upgrade is to add a matching DDR4 DIMM in the correct paired slot so the system gains both additional capacity and dual-channel performance. For A+ Core 1, candidates should recognize that RAM upgrades require matching the motherboard's supported memory technology, such as DDR4 versus DDR3, and following the board manufacturer's population rules for dual-channel operation. In real-world practice, technicians verify the supported memory type, maximum capacity, and recommended slot order in the motherboard manual or system documentation. With one 8 GB module, the user may experience paging to disk under heavier workloads. Expanding to 16 GB reduces memory pressure, and using the proper paired slot commonly enables dual-channel mode, which can improve overall responsiveness.

  • A. Correct.

    Correct. Adding a second DIMM with the same capacity, type, and speed as the existing DDR4-2666 module is the best way to increase RAM capacity while also enabling dual-channel operation on a typical motherboard when installed in the paired slot. On many boards, the correct paired slots are color-matched or documented as A2 and B2 when using two modules. This improves multitasking performance and memory bandwidth without replacing the existing RAM.

  • B. Incorrect.

    Incorrect. DDR3 and DDR4 are not cross-compatible. They use different signaling, voltages, and keying notches, so a DDR3 module will not fit or function in a DDR4 motherboard slot. A user might choose this because it offers more capacity, but the memory type must match what the motherboard supports.

  • C. Incorrect.

    Incorrect. Moving the existing module to a different slot without adding more memory does not address the user's need for better multitasking performance. The system would still have only 8 GB of RAM and would still operate in single-channel mode with one module installed.

  • D. Incorrect.

    Incorrect. Although some systems can downclock mixed-speed RAM to the slowest installed module, installing the second module in A1 is typically not the correct paired slot for dual-channel when the first module is already in A2. Also, buying DDR4-3200 does not guarantee the system will run at 3200 MT/s; it will usually operate at the motherboard and slowest module's supported speed, in this case likely 2666 MT/s.

220-1101 Question 5

Single answerHard disk drive (HDD)/solid-state drive (SSD)

A technician is upgrading several office desktops from 1 TB 7200 RPM HDDs to SSDs to improve boot time and application responsiveness. One employee works with very large video files and asks why the technician chose a 2.5-inch SATA SSD instead of another HDD with a larger cache. Which of the following best explains the main performance advantage of the SSD in this scenario?

  1. A

    The SSD provides faster random access because it has no moving parts, which greatly reduces seek time and latency

  2. B

    The SSD increases CPU clock speed during file transfers, allowing applications to open faster

  3. C

    The SSD stores data magnetically in denser platters, which improves boot speed over a 7200 RPM HDD

  4. D

    The SSD eliminates the need for system RAM caching, so large files load directly into the processor

Show answer and explanation

Correct answer: A

Explanation

The best answer is the SSD's much lower seek time and latency due to the absence of moving parts. For A+ Core 1, candidates should understand the practical difference between HDD and SSD performance: HDDs rely on mechanical movement of platters and read/write heads, while SSDs use non-volatile flash memory. As a result, SSDs typically provide much faster boot times, quicker application launches, and better responsiveness in everyday workloads. Although factors such as interface type, controller quality, and workload matter, the core best-practice explanation for replacing an HDD with an SSD is improved storage access performance, especially random I/O. This aligns with common vendor documentation from drive manufacturers and general operating system performance guidance.

  • A. Correct.

    Correct. A SATA SSD typically delivers much better random read/write performance than a mechanical HDD because it has no spinning platters or actuator arm. This means seek time and rotational latency are dramatically lower, which is why operating systems, applications, and frequently accessed files open much faster. In real-world desktop use, this is usually the primary reason users notice a major improvement after replacing an HDD with an SSD.

  • B. Incorrect.

    Incorrect. A storage upgrade does not increase the CPU's clock speed. Faster storage can reduce the time the CPU waits for data, making the system feel more responsive, but it does not change processor frequency or directly boost CPU performance.

  • C. Incorrect.

    Incorrect. This describes HDD technology, not SSD technology. HDDs use magnetic platters, while SSDs use flash memory. A larger cache on an HDD can help in some workloads, but it does not remove the mechanical delays that make HDDs slower than SSDs for booting and launching applications.

  • D. Incorrect.

    Incorrect. SSDs do not replace the function of system RAM or caching. The operating system still uses RAM and cache mechanisms to improve performance. Data is not loaded directly into the processor from the SSD in the way this option suggests.

220-1101 Question 6

Single answerWireless cards

A technician replaces a failed wireless card in a user's laptop. After the replacement, the laptop detects nearby Wi-Fi networks, but it cannot maintain a stable connection unless it is very close to the access point. Ethernet works normally, and other nearby wireless devices have strong signal strength. Which action is the MOST likely to resolve the issue?

  1. A

    Reinstall the TCP/IP protocol stack in the operating system

  2. B

    Reconnect the wireless antenna leads to the correct terminals on the replacement card

  3. C

    Change the access point from WPA2 to WEP for compatibility

  4. D

    Disable Bluetooth in Device Manager to free the wireless radio

  5. E

    Assign a static IP address to the wireless adapter

Show answer and explanation

Correct answer: B

Explanation

The key clue is that the problem started immediately after replacing the internal wireless card and that the laptop only works reliably when it is very close to the access point. That symptom strongly indicates an antenna connection problem rather than a software, security, or IP configuration issue. Internal laptop Wi-Fi adapters typically depend on properly attached internal antenna leads routed through the display assembly. If those leads are not connected securely, the card may still function at a minimal level but with severely reduced range and unstable performance. This aligns with standard laptop hardware troubleshooting best practices: verify physical connections first after a field-replaceable component is installed. Vendor service manuals for laptops commonly note proper reconnection of WLAN antenna cables during wireless card replacement, and wireless troubleshooting guidance from manufacturers frequently identifies loose antenna leads as a common cause of weak signal after service.

  • A. Incorrect.

    Incorrect. A damaged or misconfigured TCP/IP stack would more likely affect IP communication after association, not cause very weak signal range that improves only when the laptop is close to the access point. The laptop can already see networks, which points more toward an RF or antenna-related problem than a protocol stack issue.

  • B. Correct.

    Correct. Laptop wireless cards commonly use one or two tiny antenna leads that must be firmly connected to the card's main/aux terminals. If these leads are loose, disconnected, or swapped in a way that affects performance, the system may still detect networks but have very poor range and unstable connectivity. This is a common post-repair issue when replacing internal Wi-Fi cards.

  • C. Incorrect.

    Incorrect. Lowering security from WPA2 to WEP is not an appropriate fix for weak signal or poor range, and WEP is obsolete and insecure. Security mismatch issues typically prevent successful authentication rather than causing the connection to work only when very close to the access point.

  • D. Incorrect.

    Incorrect. Bluetooth and Wi-Fi can coexist on combo cards, and disabling Bluetooth is not the primary fix for dramatically reduced Wi-Fi range after a card replacement. While 2.4 GHz interference can occur in some cases, the timing of the problem immediately after hardware replacement strongly suggests an installation issue instead.

  • E. Incorrect.

    Incorrect. IP addressing affects network communication after a wireless link is established. It does not correct poor reception, low signal strength, or a connection that is only usable at very short distances from the access point.

220-1101 Question 7

Single answerPhysical privacy and security components

A technician is deploying new all-in-one PCs at a hospital registration desk. Staff members work in a public waiting area, and patients often stand beside the desk while paperwork is being completed. Management wants to reduce the chance of patients viewing protected health information on the screen without significantly affecting normal keyboard and mouse use. Which physical security component should the technician install?

  1. A

    Privacy screen filter

  2. B

    Kensington cable lock

  3. C

    Biometric reader

  4. D

    USB port blocker

Show answer and explanation

Correct answer: A

Explanation

The best answer is the privacy screen filter because the scenario is specifically about preventing unauthorized viewing of sensitive data in a public-facing workspace. In A+ Core 1, physical privacy and security components include items such as privacy screens, cable locks, biometrics, and port locks, but each solves a different problem. A privacy screen is the appropriate control when the main risk is visual exposure of data, sometimes called shoulder surfing. This aligns with common healthcare and security best practices for protecting confidential information in public areas, especially where regulated data such as protected health information is displayed.

  • A. Correct.

    Correct. A privacy screen filter narrows the viewing angle of the display so people standing to the side cannot easily read the contents on the screen. This is a standard physical privacy control for workstations in public or semi-public areas such as reception desks, nursing stations, and check-in counters.

  • B. Incorrect.

    Incorrect. A Kensington cable lock helps physically secure the computer to a desk or other fixed object to deter theft. It does not prevent nearby people from viewing sensitive information displayed on the monitor.

  • C. Incorrect.

    Incorrect. A biometric reader helps control logical access by verifying a user's identity, such as through a fingerprint. While it can improve authentication security, it does not address shoulder surfing or visual exposure of on-screen patient information.

  • D. Incorrect.

    Incorrect. A USB port blocker helps prevent unauthorized use of USB ports, such as connecting removable storage or peripherals. This can support device security, but it does not limit who can see the display in a public area.

220-1101 Question 8

Single answerBiometrics

A company deploys fingerprint readers on shared Windows laptops used by warehouse supervisors. Several users report that the readers frequently fail to recognize employees who have worn fingerprints from manual labor, causing delays at the start of each shift. Management wants to keep biometric sign-in in place but reduce login failures without significantly lowering security. Which action should the technician recommend?

  1. A

    Enroll each user with multiple fingers so an alternate fingerprint can be used if one finger is difficult to scan

  2. B

    Disable biometrics and switch all users to shared generic passwords to prevent failed fingerprint scans

  3. C

    Lower the account lockout threshold so users can retry fingerprint authentication more times before being locked out

  4. D

    Replace fingerprint readers with RFID proximity badges because RFID is also a biometric factor

Show answer and explanation

Correct answer: A

Explanation

The best recommendation is to enroll multiple fingers for each user. In real-world biometric deployments, fingerprint quality can vary due to occupation, skin condition, or injury. Warehouse and construction environments commonly create recognition problems because fingerprints may become worn or damaged. Using alternate enrolled fingers improves successful authentication while maintaining biometric controls. This aligns with common vendor and operating system guidance for biometric setup, including best practices seen in Windows Hello and enterprise biometric deployments: capture good-quality templates and enroll backup fingers when available. The other options either weaken security, fail to solve the actual issue, or confuse biometrics with other authentication factors.

  • A. Correct.

    Correct. Enrolling multiple fingers is a practical best practice for fingerprint authentication, especially for users whose primary fingerprint may be hard to read because of wear, cuts, dirt, or dry skin. This keeps biometric authentication in use while improving usability and availability without fundamentally weakening security.

  • B. Incorrect.

    Incorrect. Shared generic passwords would reduce accountability and weaken security. Biometrics are intended to uniquely identify or verify individual users, while shared credentials make auditing and nonrepudiation much harder.

  • C. Incorrect.

    Incorrect. Account lockout settings are related to repeated failed authentication attempts, but they do not address the root problem: poor fingerprint readability. Also, lockout thresholds are typically associated with password policies and do not improve biometric capture quality.

  • D. Incorrect.

    Incorrect. RFID proximity badges are not biometrics. They are a possession factor, not an inherence factor. While badges may be useful in some environments, this option is based on a misunderstanding of authentication factor types.

220-1101 Question 9

Single answerNear-field scanner features

A field technician is helping users in a warehouse pair company smartphones with handheld barcode scanners. The phones include a near-field scanner feature, and management wants the fastest setup method with the lowest chance of pairing to the wrong device in a crowded area. Which action should the technician take?

  1. A

    Hold the phone within a few centimeters of the scanner's NFC tag or pairing area to initiate pairing

  2. B

    Search for the scanner over Bluetooth from 30 feet away and use near-field scanning only after the connection is established

  3. C

    Enable the phone's infrared port and point it directly at the scanner to transfer the pairing information

  4. D

    Connect the phone to the scanner's Wi-Fi network so the near-field scanner can read the device over the LAN

Show answer and explanation

Correct answer: A

Explanation

The best answer is to place the phone very close to the scanner's NFC tag or designated pairing area. On A+ Core 1, candidates should recognize that near-field communication is a very short-range wireless technology designed for secure, convenient exchanges at close proximity. A practical use is tap-to-pair, where NFC exchanges enough information to identify the target device and may trigger Bluetooth pairing or device configuration. This short range is a key feature because it reduces unintended connections in environments with many nearby devices. CompTIA A+ objectives commonly expect familiarity with mobile device wireless features and distinctions among NFC, Bluetooth, infrared, and Wi-Fi. Manufacturer documentation for smartphones, payment terminals, and enterprise peripherals also consistently describes NFC as operating at close range rather than across a room or over a network.

  • A. Correct.

    Correct. Near-field communication works only at very short range, typically a few centimeters. This makes it useful for quick tap-to-pair or tap-to-configure tasks while reducing accidental connections to nearby devices. In a crowded warehouse, requiring close proximity helps ensure the technician pairs with the intended scanner.

  • B. Incorrect.

    Incorrect. Standard Bluetooth discovery can work over much longer distances than NFC and is more likely to show multiple nearby devices in a crowded environment. NFC is commonly used to simplify or initiate Bluetooth pairing, not as a feature that becomes useful only after a long-range Bluetooth connection is already made.

  • C. Incorrect.

    Incorrect. Infrared requires line-of-sight and is a different technology from near-field communication. Modern smartphones used in enterprise environments typically rely on NFC for close-range pairing, not IR ports for this task. Choosing this option reflects confusion between short-range wireless technologies.

  • D. Incorrect.

    Incorrect. NFC does not operate by reading devices over a Wi-Fi LAN. It is a close-range radio technology used for small data exchanges such as identification, authentication, or initiating another connection method. Joining a Wi-Fi network is unrelated to the phone's near-field scanner feature.

220-1101 Question 10

Single answerWi-Fi antenna connector/placement

A technician is replacing a damaged external Wi-Fi antenna on a desktop PC used in a warehouse office. The PC has a wireless adapter with two small threaded antenna ports on the rear bracket. The replacement antenna kit includes cables labeled RP-SMA and SMA. The technician also notices the PC is pushed under a metal desk beside a filing cabinet, and users report weak signal and frequent disconnects. Which action should the technician take FIRST to restore proper Wi-Fi operation while avoiding hardware mismatch?

  1. A

    Verify the adapter uses RP-SMA connectors, attach the correct antenna, and move the antenna/PC away from the metal obstruction if possible

  2. B

    Attach the SMA antenna to either port because Wi-Fi antenna connectors are interchangeable on most consumer adapters

  3. C

    Leave the antenna disconnected and instead increase the access point transmit power to compensate for signal loss

  4. D

    Connect only one antenna, because the second antenna port is used only for Bluetooth on dual-band adapters

Show answer and explanation

Correct answer: A

Explanation

This question tests two practical A+ Core 1 skills: identifying the correct Wi-Fi antenna connector and applying good antenna placement practices. In real deployments, external desktop Wi-Fi antennas commonly use RP-SMA connectors, and technicians must confirm connector type before attaching a replacement antenna. SMA and RP-SMA are visually similar but are keyed differently by the center conductor arrangement. From a placement perspective, RF best practice is to avoid placing antennas behind or under metal surfaces, filing cabinets, and desks because these objects can block, absorb, or reflect signal. Moving the antenna or system to a less obstructed location is often one of the fastest ways to improve signal strength and stability. These actions align with standard wireless troubleshooting guidance from hardware vendors and general WLAN deployment best practices.

  • A. Correct.

    Correct. Many desktop Wi-Fi adapters use RP-SMA connectors for removable antennas, and using the correct connector type is important to avoid incompatibility or damage. After confirming the proper antenna connection, improving antenna placement by moving it away from metal desks, cabinets, and other obstructions is a practical first step because metal can attenuate and reflect RF signals, reducing signal quality and causing disconnects.

  • B. Incorrect.

    Incorrect. SMA and RP-SMA are not interchangeable even though they look similar. Their center pin/socket arrangement differs, so forcing the wrong connector can damage the antenna or adapter and will not provide a proper RF connection. This is a common misconception because the threaded shells appear alike.

  • C. Incorrect.

    Incorrect. A Wi-Fi device should not be operated without the required antenna attached, and changing access point power does not address the immediate issue of a missing or mismatched client antenna. Also, transmit power changes may not solve poor client-side reception caused by bad antenna placement or connector mismatch.

  • D. Incorrect.

    Incorrect. On many Wi-Fi adapters, two external antenna ports are used for Wi-Fi functions such as MIMO/diversity, not because one is dedicated to Bluetooth. While some combo cards support Bluetooth separately, the visible dual antenna ports on a desktop Wi-Fi bracket are typically both for the WLAN radio system. Using only one antenna can reduce performance and reliability.
