Reinforce 220-1101 concepts with active-recall study cards covering all 5 blueprint domains. Each card shows the question on the front and the correct answer with a full explanation on the back.
Flashcards work through active recall — the process of retrieving information from memory rather than passively re-reading it. Research consistently shows that active recall produces stronger, longer-lasting memory than re-reading study guides. For 220-1101 preparation, this means flashcards are one of the highest-return study tools available.
Attempt recall first
Read the 220-1101 question on each card, pause, and attempt to formulate the answer in your own words before revealing. This retrieval attempt — even if wrong — dramatically strengthens memory compared to immediately reading the answer.
Review wrong cards again
When you get a card wrong, note it and add it back to your review pile. Spaced repetition — seeing difficult cards more frequently — is the mechanism that makes flashcard study far more efficient than linear reading.
Study by domain
Group your 220-1101 flashcard sessions by domain for the first 3–4 weeks. Master one domain before moving to the next. In the final week, shuffle all cards together to test cross-domain recall — which is what the real 220-1101 exam requires.
Short sessions beat marathon reviews
20–30 flashcard cards per session, done daily, produces better retention than a single 200-card marathon session. Five short daily sessions per week over 4 weeks gives you over 400 total card reviews — enough to reliably pass 220-1101.
Sample cards from the 220-1101 flashcard bank. Read the question, think of the answer, then read the explanation below.
A user reports that the touchscreen on their smartphone is unresponsive in the bottom-left corner but works everywhere else. Which component is most likely failing?
Digitizer failure
The touchscreen's digitizer is the layer responsible for detecting touch input. When a specific region of the screen becomes unresponsive while the display itself remains functional, it indicates a localized failure of the digitizer's grid or controller, not the LCD panel.
A technician is adding a wireless access point (AP) in an outbuilding connected via Ethernet to the main office network (192.168.1.0/24). After configuring the AP with a static IP of 192.168.1.250, clients can connect to Wi-Fi but cannot access the internet. The main office devices have no issues. What is the most likely cause?
The new AP has its DHCP server enabled
The most likely cause is that the new AP has its DHCP server enabled. When the AP assigns IP addresses to clients via its own DHCP, those clients receive an IP address from a different subnet or scope than the main office network (192.168.1.0/24). This prevents them from reaching the default gateway (e.g., 192.168.1.1) and thus the internet, while the AP itself remains reachable on its static IP. Disabling the AP's DHCP server and allowing clients to obtain addresses from the main network's DHCP server resolves the issue.
A technician is assembling a workstation for video editing. The motherboard has two DIMM slots and supports dual-channel DDR4-3200 memory. The user requests 32 GB of RAM. Which memory configuration will provide the best performance?
Two 16 GB DDR4-3200 modules
Option C is correct because it uses two identical 16 GB DDR4-3200 modules in the motherboard's two DIMM slots, enabling dual-channel memory operation. Dual-channel mode doubles the memory bandwidth compared to single-channel, which is critical for video editing workloads that involve large data transfers. The DDR4-3200 speed matches the motherboard's supported speed, ensuring optimal performance without any speed mismatches.
A company wants to migrate its on-premises email server to the cloud. The IT director insists that the new solution require no management of the underlying operating system, application server, or patching. Which cloud service model should the organization choose?
Software as a Service (SaaS)
Software as a Service (SaaS) provides a fully managed application delivered over the internet. The provider handles all underlying infrastructure, operating system, application server, and patching, meeting the IT director's requirement for zero management of those layers. In this scenario, the email service is consumed as a ready-to-use application, such as Microsoft 365 Exchange Online or Google Workspace.
After a power outage, a desktop computer will not power on. The PSU fan does not spin, and no LEDs are lit. The technician tests the power supply with a PSU tester; all voltages are within spec. A multimeter reading at the motherboard's power button header shows 3.3V when the button is pressed. The power supply is also confirmed to work when tested in another system. What is the most likely cause?
The motherboard has failed
The motherboard has failed because the PSU passes all voltage tests and works in another system, yet the desktop shows no signs of power (no fan spin, no LEDs) when connected to this motherboard. The 3.3V reading at the power button header indicates the motherboard is receiving standby power and the button is functioning, but the motherboard is not completing the power-on sequence (pulling PS_ON# low) to start the PSU. This points to a failed motherboard, likely a short or damaged power regulation circuit.
A technician is assembling a new desktop computer with an AMD Ryzen 5 CPU on a B550 motherboard. After installing the CPU, heatsink, RAM, and graphics card, and connecting all power cables, the technician powers on the system. The case fans spin, the motherboard LEDs light up, but there is no display output and no beep codes. The motherboard has a set of diagnostic LEDs; the LED labeled 'CPU' remains lit. Which of the following should the technician check FIRST?
Verify that the 8-pin CPU power cable is connected to the motherboard
The CPU diagnostic LED remaining lit indicates a problem with the CPU or its power delivery. The most common cause is the 8-pin EPS12V CPU power cable not being connected, which supplies dedicated 12V power to the processor. Without this cable, the CPU cannot initialize, even though case fans and motherboard LEDs receive power from the 24-pin ATX connector.
A technician is building a desktop computer and applies thermal paste to the CPU before installing the heatsink. The technician uses significantly more paste than recommended. Which of the following is the most likely consequence of this action?
The CPU will overheat because excess paste reduces heat transfer efficiency
Excess thermal paste acts as an insulator rather than a conductor, creating a thicker layer that impedes heat transfer from the CPU die to the heatsink base. This reduces thermal conductivity efficiency, causing the CPU to run hotter and potentially throttle or fail under load.
A technician is building a custom workstation for 3D rendering. The components include an AMD Ryzen 7 5800X CPU, a B550 motherboard (box states 'AMD Ryzen 3000 desktop ready'), two 16GB DDR4-3600 modules (on the QVL), and a dedicated GPU. The system powers on, case fans spin, and the CPU fan spins, but the motherboard’s CPU debug LED remains lit and there is no display. The technician has reseated the CPU and found no bent pins. The RAM and GPU have been verified working in another system. The PSU is a known-good 750W unit. Which of the following should the technician do NEXT?
Upgrade the motherboard BIOS using the BIOS flashback feature
The B550 motherboard is labeled 'AMD Ryzen 3000 desktop ready,' meaning its factory BIOS supports Ryzen 3000 CPUs but not Ryzen 5000 (Vermeer) CPUs like the Ryzen 7 5800X. The CPU debug LED staying lit indicates the motherboard cannot initialize the CPU, which is a classic symptom of an incompatible BIOS version. Using the BIOS flashback feature allows the technician to update the BIOS without a compatible CPU installed, enabling support for the Ryzen 5000 series.
A technician installs a new M.2 SATA SSD into a desktop motherboard. The SSD is not detected in the BIOS. The technician has verified that the SSD is compatible with the motherboard and that it is fully seated. Which of the following is the MOST likely cause?
The M.2 slot shares bandwidth with a SATA port that is in use
The most likely cause is that the M.2 SATA SSD shares bandwidth with a specific SATA port on the motherboard. When an M.2 SATA SSD is installed, it often disables one or more SATA ports (commonly SATA port 5 or 6) because the M.2 slot and those SATA ports share the same PCIe/SATA lanes from the chipset. If a hard drive or optical drive is already connected to that shared SATA port, the M.2 SSD will not be detected in the BIOS, even though it is compatible and properly seated.
A small business wants to migrate its internal applications to the cloud to reduce hardware maintenance costs. They wish to retain control over the application code and configuration but do not want to manage the underlying operating system or runtime environment. Which cloud service model BEST meets their needs?
Platform as a Service (PaaS)
Platform as a Service (PaaS) provides a managed platform where the customer controls the application code and configuration, while the cloud provider handles the underlying OS and runtime environment. This aligns with the requirement to reduce hardware maintenance costs without managing the OS or runtime.
A technician replaced the screen assembly on a smartphone. After reassembly, the phone powers on and displays correctly, but the touch screen is unresponsive. Which of the following should the technician check FIRST?
Ensure the digitizer ribbon cable is properly seated
The digitizer ribbon cable connects the touch-sensitive layer of the screen to the motherboard. If it is loose or improperly seated after reassembly, the touch input cannot be registered even though the display (LCD/OLED) works fine. This is the most likely cause given the recent disassembly and should be checked first before any software or replacement steps.
A technician is assembling a desktop computer using an Intel LGA1151 socket motherboard. The CPU has been installed correctly with thermal paste and a heatsink. When the power button is pressed, the system powers on for about three seconds, then shuts off, and then repeatedly attempts to restart. The CPU cooler fan spins normally during that time. Which of the following is the MOST likely cause?
The 4+4 pin EPS12V power connector is not plugged into the motherboard
The 4+4 pin EPS12V connector provides dedicated power to the CPU. Without it, the CPU cannot initialize, causing the motherboard's fail-safe to power off after a few seconds and then repeatedly attempt to restart. The cooler fan spinning normally indicates the system is receiving basic power, but the CPU lacks the necessary voltage to complete POST.
A technician is building a new desktop computer and needs to connect the front-panel power button to the motherboard. Which of the following connectors or headers is designed for this purpose?
F_PANEL header
The F_PANEL header is a dedicated connector block on the motherboard that interfaces with the front-panel controls of the computer case, including the power button, reset button, and status LEDs. It uses a specific pinout to carry the momentary contact signal from the power button to the motherboard's power management circuitry, allowing the system to power on or off.
A small office recently installed 12 new VoIP phones. Each phone is connected via an Ethernet cable to a 24-port managed PoE+ switch. The switch is powered on, and the network cables are properly terminated. However, none of the VoIP phones power on. The switch's power LED is solid, but the port LEDs remain off. Which of the following is the MOST likely cause?
The switch's PoE power budget has been exceeded
The switch's power LED is solid, indicating it has power, but the port LEDs are off, meaning no devices are being powered. Since all 12 VoIP phones are connected to a 24-port PoE+ switch, the most likely cause is that the total power draw of 12 phones exceeds the switch's PoE power budget. PoE+ (802.3at) provides up to 30W per port, but the switch has a limited total power supply (e.g., 250W), and 12 phones at 15-30W each could easily exceed that budget, causing the switch to deny power to all ports.
A technician installed a new high-end graphics card in a desktop PC. The system powers on, fans spin, but the monitor remains black. The monitor works fine when connected to the motherboard's integrated video port. The technician has reseated the graphics card, connected the necessary PCIe power cables, and verified the card is fully inserted in the primary PCIe x16 slot. Which of the following is the MOST likely next step to resolve the issue?
Check the BIOS/UEFI settings to ensure the primary display is set to PCIe
The correct answer is C because when a discrete graphics card is installed, the BIOS/UEFI must be configured to use the PCIe slot as the primary display adapter. If the system defaults to the integrated GPU, the monitor will remain black when connected to the new card, even though the card is powered and seated correctly. Checking and setting the primary display to PCIe in BIOS/UEFI directly addresses this common misconfiguration.
A technician is assembling a new desktop computer. After installing the CPU, heat sink, RAM, and power supply, the system powers on for a few seconds and then shuts down. The CPU fan spins during that time. The technician has verified that the power supply connections are secure. Which of the following should the technician check FIRST?
The thermal paste application between the CPU and heat sink
The system powers on for a few seconds and then shuts down, which is a classic symptom of thermal overload protection (Tjmax) being triggered. Since the CPU fan spins, power delivery is present, but without proper thermal paste, the CPU rapidly exceeds its critical temperature threshold, causing an immediate shutdown to prevent damage.
A technician is building a database server that requires fast random read/write performance for small data blocks. Which of the following storage devices will BEST meet this requirement?
An NVMe M.2 solid-state drive
An NVMe M.2 solid-state drive is the best choice because it connects directly via the PCIe bus, bypassing the SATA controller and its protocol overhead. This provides dramatically lower latency and higher IOPS (input/output operations per second), which is essential for fast random read/write performance on small data blocks in a database server.
A technician is assembling a new desktop PC. The motherboard has integrated graphics and a discrete PCIe graphics card is installed. The monitor is connected to the discrete graphics card. When powered on, the system fans spin and the power LED lights, but there is no video output and no POST beep codes. Which of the following should the technician do FIRST?
Connect the monitor to the integrated graphics port on the motherboard
The correct first step is to connect the monitor to the integrated graphics port on the motherboard. Since the system powers on (fans spin, power LED lights) but shows no video and no POST beep codes, the discrete graphics card may be faulty or improperly seated. By switching to the integrated graphics, the technician can quickly determine if the discrete card is the cause of the no-display issue without replacing components. This isolates the problem efficiently, as the integrated graphics are known to work if the CPU and motherboard are functional.
A technician is building a desktop computer. After installing all components, the computer powers on. All fans spin, and the LED on the motherboard lights up, but there is no display output. The monitor and cable are known to work. The technician has already reseated the RAM and the graphics card. Which of the following should the technician check NEXT?
Verify that the 4/8-pin CPU power connector is securely connected to the motherboard.
The 4/8-pin CPU power connector supplies dedicated 12V power to the processor. If it is loose or disconnected, the CPU will not initialize, causing the system to power on (fans spin, LEDs light) but produce no display output. Since the monitor, cable, RAM, and graphics card have been verified, the next logical step is to check this critical power connection.
A technician is assembling a new desktop PC. The technician needs to connect the power button, reset button, HDD LED, and power LED from the case to the motherboard. Which of the following should the technician consult for the correct pin layout?
Motherboard manual
The motherboard manual contains the front panel header pinout diagram, which specifies the exact layout for connecting the power button, reset button, HDD LED, and power LED from the case. Each motherboard manufacturer uses a unique pin arrangement, so consulting this manual ensures correct polarity and prevents damage to the motherboard or LEDs.
A technician is building a new desktop computer. After installing the CPU, RAM, and a high-end graphics card, the system powers on but shuts down after about 10 seconds. The CPU fan spins erratically during this time. The technician has verified the CPU is supported and properly seated. The heatsink came with pre-applied thermal paste. Which of the following should the technician check NEXT?
Ensure the CPU fan cable is connected to the CPU_FAN header
The CPU fan cable must be connected to the motherboard's CPU_FAN header, not a chassis fan header, because the system monitors the CPU_FAN header for a tachometer signal. If the fan is connected elsewhere, the motherboard detects no fan RPM on the CPU_FAN header and may shut down after a few seconds to prevent CPU overheating, even if the fan is spinning. The erratic fan behavior suggests the fan is receiving power but not being properly controlled or monitored by the CPU_FAN header.
A small office has 18 computers that need to be connected to share files and access the internet. The ISP provides a modem with a single Ethernet port. The office router has four LAN ports. Which device should the technician add to enable all 18 computers to connect to the network?
B. A switch
A switch is the correct device because it provides multiple Ethernet ports (typically 24 or 48) and operates at Layer 2, forwarding frames based on MAC addresses. This allows all 18 computers to connect to the network, share files, and access the internet through the existing router, which only has four LAN ports.
A network technician is installing a new fiber optic link between two switches located in different buildings. The technician uses identical SFP modules on both ends and connects them with a single fiber patch cable. After powering on, the link lights on both switches remain off. The technician verifies the SFP modules are compatible with the switches and that the cable is not damaged. Which of the following should the technician check NEXT?
Swap the transmit and receive connections at one end of the fiber cable
The correct answer is A because fiber optic communication requires two separate strands: one for transmitting (TX) and one for receiving (RX). If a single fiber patch cable is used, it typically contains two fibers, but the connectors must be crossed at one end so that the TX of one switch connects to the RX of the other. Since the link lights are off despite compatible SFPs and an undamaged cable, the most likely issue is a polarity mismatch, where both ends are wired straight through (TX to TX, RX to RX), preventing the optical signal from being received.

Both flashcards and practice questions are evidence-based study tools. The difference is in what they train:
Flashcards — concept retention
Best for memorising definitions, acronyms, protocol behaviours, command syntax, and conceptual distinctions. Use flashcards to build the foundational vocabulary that 220-1101 questions assume you know.
Best in: weeks 1–3
Practice tests — application
Best for applying concepts to realistic scenarios, eliminating distractors, and building exam stamina.220-1101 questions test scenario reasoning — not just recall — so practice tests are essential.
Best in: weeks 3–6
The most effective 220-1101 study plan combines both: use flashcards for the first 2–3 weeks to build conceptual foundations, then shift to practice tests and mock exams in the final 2–3 weeks to apply and benchmark that knowledge. Most candidates who pass on their first attempt use both tools.
