A graphics designer reports that while executing GPU-intensive 3D rendering tasks, their desktop workstation monitor exhibits random colored pixels scattered across the screen (digital artifacts) and screen tearing. During peak rendering loads, the display signal suddenly cuts out completely, putting the monitor into power-saving mode while the host PC remains powered on and operational. Which of the following are the MOST likely root causes for these combined symptoms? (Select TWO.)

Select all that apply

Show answer & explanation

Answer: Overheating GPU VRAM or defective video memory chips failing under high graphics processing loads; Insufficient power supply unit (PSU) wattage or failing +12V PCIe power delivery during peak GPU draw

Answer

The most likely root causes are overheating or failing GPU VRAM modules and an inadequate or failing power supply unit (+12V PCIe rail) under peak processing load.
Visual artifacts such as random colored pixels, checkerboard patterns, or screen tearing during intensive 3D rendering indicate overheating or failing VRAM on the graphics adapter. Meanwhile, a sudden loss of display signal putting the monitor into power-saving mode specifically when GPU rendering load spikes indicates that the power supply unit (PSU) cannot deliver sufficient wattage or stable +12V power to the graphics card, causing the card to trip its safety shutoff.

Step-by-Step Solution

1
Analyze the reported visual artifacts (random colored dots/pixels during heavy 3D rendering).
Identify VRAM overheating or video memory degradation as the physical cause of rendering corruption.
Hardware-level memory errors on the graphics adapter directly distort frame buffer output.
2
Analyze the secondary symptom (sudden complete video signal loss into power-saving mode under peak render loads while PC stays on).
Identify power delivery failure (PSU power draw overload on the +12V graphics rail) forcing GPU thermal/power trip shutdown.
When GPUs experience brownouts or severe voltage drops under load, the card resets/shuts off its display output.

A desktop computer in a office environment is unable to access local network resources or the internet. Running `ipconfig /all` on the workstation displays an IPv4 address of 169.254.45.12169.254.45.12. Upon physical inspection, the technician observes that the link light on the workstation's network interface card (NIC) is completely unlit. Which of the following initial troubleshooting steps should the technician perform to address this issue? (Select TWO.)

Select all that apply

Show answer & explanation

Answer: Test or replace the Ethernet patch cable connected between the workstation and the wall jack.; Verify that the corresponding switch port in the patch panel room is enabled and showing physical link activity.

Answer

The technician should test or replace the Ethernet patch cable and verify that the corresponding switch port is enabled and showing physical link activity.
The presence of an Automatic Private IP Addressing (APIPA) address (169.254.x.x169.254.x.x) combined with an unlit NIC link light points directly to a Layer 1 (Physical layer) failure. Testing or replacing the Ethernet patch cable and verifying that the network switch port is active and enabled directly troubleshoot the physical link layer. Establishing a physical connection is required before the client can reach a DHCP server.

Step-by-Step Solution

1
Analyze the diagnostic output and physical indicators.
The IP address 169.254.45.12169.254.45.12 indicates an APIPA assignment, and the unlit NIC light signifies a physical layer link loss.
Troubleshooting methodology dictates beginning at Layer 1 (Physical layer) when physical link indicators fail.
2
Inspect and test local physical layer cabling.
Testing or replacing the Ethernet patch cable confirms whether cable damage is causing the unlit link light.
Faulty or disconnected patch cables are a primary cause of lost Ethernet link signals.
3
Inspect infrastructure physical layer components.
Verifying that the network switch port is enabled ensures signal transmission from the network infrastructure end.
A disabled port or inactive switch port prevents physical link establishment regardless of client-side configuration.

Question 626Question →

A technician is troubleshooting network connectivity on a Windows workstation that currently has an Automatic Private IP Addressing (APIPA) address assigned. The technician wants to release the existing address, request a new lease from the DHCP server, and inspect the updated configuration parameters. Place the following troubleshooting steps in the correct chronological order from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Open the Command Prompt with administrator privileges, execute ipconfig /release, execute ipconfig /renew, and finally execute ipconfig /all.
Refreshing a DHCP configuration using Windows command-line tools requires an elevated Command Prompt window so that network adapter settings can be modified. Executing 'ipconfig /release' drops the existing APIPA or invalid IP settings. Next, 'ipconfig /renew' prompts the workstation to request a new IP address lease from the DHCP server. Finally, 'ipconfig /all' displays comprehensive network interface details, allowing the technician to confirm that a valid IP address, subnet mask, default gateway, and DNS servers were obtained.

Step-by-Step Solution

1
Launch the Command Prompt as an Administrator.
An elevated CLI window opens with administrative rights.
Network configuration changes require administrative privileges on Windows workstations.
2
Run the command ipconfig /release.
The current IP configuration (APIPA address) is cleared from the adapter.
The existing bound IP parameters must be dropped before asking for a new DHCP lease.
3
Run the command ipconfig /renew.
The network interface issues a DHCP broadcast and receives a new valid IP address lease.
This command forces the operating system to request fresh network parameters from the DHCP server.
4
Run the command ipconfig /all.
Full interface configuration settings (MAC address, IP address, Subnet Mask, Default Gateway, DNS Servers) are displayed.
Viewing the detailed output confirms that valid IP parameters were assigned properly.

A system technician installs a new high-performance M.2 PCIe NVMe solid-state drive (SSD) into an open M.2 slot on a workstation motherboard to expand storage. After powering on the computer, the system boots into the operating system normally, but the new drive is not listed in Disk Management or Device Manager. The technician verifies that the drive is seated correctly and firmly secured with the standoff screw. Which of the following is the MOST likely cause of this issue?

Show answer & explanation

Answer: The motherboard M.2 slot is wired only for SATA-protocol drives and lacks PCIe protocol support.

Answer

The motherboard M.2 slot is wired only for SATA-protocol drives and lacks PCIe protocol support.
Although M.2 drives use a standardized form factor, the underlying connection protocol can be either SATA or PCIe (NVMe). Many motherboard M.2 slots are keyed for specific protocols or share bandwidth with SATA ports. If an NVMe drive is placed into an M.2 slot wired solely for SATA, the system host bus adapter cannot detect the drive.

Step-by-Step Solution

1
Analyze the reported hardware symptom.
The M.2 PCIe NVMe SSD is physically compatible with the slot keying and properly seated, but unrecognized by the OS and system firmware.
M.2 physical connectors share form factors across different bus protocols (SATA vs. PCIe/NVMe).
2
Compare protocol standards supported by M.2 slots.
Some legacy or budget motherboards feature M.2 slots routed exclusively to the SATA controller rather than PCIe lanes.
If an NVMe (PCIe) drive is installed in a SATA-only M.2 slot, the host controller cannot communicate with the drive.
3
Identify the correct troubleshooting conclusion.
Confirming motherboard slot specification for PCIe NVMe support is the primary diagnostic requirement.
Protocol mismatch explains complete non-detection despite proper physical installation.

A help desk technician is troubleshooting a Windows 11 client workstation that is failing to resolve internal domain names after a server IP migration. The DNS server records have already been updated, but the client workstation continues attempting to connect to the old IP address. Which command-line switch should the technician execute with the ipconfig utility to clear the local DNS resolver cache?

Show answer & explanation

Answer: ipconfig /flushdns

Answer

The command ipconfig /flushdns clears and resets the local DNS resolver cache on a Windows client machine.
Running ipconfig /flushdns immediately purges stored DNS name resolution records on a Windows client. This is the standard operational procedure when host-to-IP mappings change and the client machine needs to query the DNS server for current records.

Step-by-Step Solution

1
Identify the underlying issue causing stale IP lookup results
The client workstation relies on local cached DNS records rather than querying the DNS server.
Windows maintains a local DNS resolver cache to optimize name resolution speed, which can retain outdated host-to-IP mappings after server changes.
2
Select the correct command-line switch to purge cached records
Executing ipconfig /flushdns empties the local resolver cache.
Flushing the cache forces the OS to query the configured DNS server directly for updated hostname mappings.

A tier-2 systems technician is configuring a custom line-of-business background process on a workstation running Windows 11 Pro. The process must automatically attempt to restart itself upon the first and second unhandled crashes, execute an automated maintenance script on any subsequent crash, and operate under a dedicated local service account. Additionally, the technician needs to troubleshoot why the process fails to launch by verifying which specific underlying system services must be running before this process can start. Which administrative utility and tab combination should the technician use to complete these configuration and diagnostic steps?

Show answer & explanation

Answer: Services (services.msc) using the Recovery tab to configure failure actions and the Dependencies tab to inspect prerequisite system components.

Answer

The technician should open the Services console (services.msc), use the Recovery tab to set first, second, and subsequent crash actions, and inspect the Dependencies tab to determine required prerequisite services.
The Services console (services.msc) contains dedicated property sheets for background services. The Recovery tab allows administrators to configure automated responses to service failures, including restarting the service after the first and second crashes and executing a custom batch or PowerShell script on subsequent failures. The Dependencies tab explicitly details system dependencies, showing which underlying services must be active before the target service can start.

Step-by-Step Solution

1
Launch the Windows Services management console by executing services.msc in the Run dialog or Search bar.
The Services management console opens, displaying all installed system and third-party background services.
Services.msc is the primary administrative tool for managing background service states, startup types, logon identities, recovery actions, and dependency mappings.
2
Open the Properties window for the target service and navigate to the Recovery tab.
The Recovery settings interface becomes accessible.
The Recovery tab provides specific drop-down configurations for 'First failure', 'Second failure', and 'Subsequent failures', allowing the administrator to select 'Restart the Service' for initial failures and 'Run a Program' (to execute a script) for subsequent failures.
3
Navigate to the Dependencies tab within the same Properties window.
Two hierarchical lists are shown: system components that the service depends on, and services that depend on this service.
Inspecting 'This service depends on the following system components' identifies prerequisite services that must be running for the target service to initialize successfully.

A systems support technician is troubleshooting a departmental laser printer that produces output with faint, repeating ghost images of previously printed text farther down each page. The technician replaces the toner cartridge assembly (which includes a integrated photosensitive drum), but the ghosting issue continues to occur on every print job. Which of the following components is the most likely cause of this print quality defect?

Show answer & explanation

Answer: A damaged or improperly heated fuser roller assembly

Answer

A damaged or improperly heated fuser roller assembly is the most likely cause because ghosting that persists after replacing the photosensitive drum indicates toner is failing to properly fuse or is sticking to the fuser roller.
Ghosting occurs when an image is repeated faintly down the page. There are two main causes: drum ghosting and fuser ghosting. Because replacing the toner cartridge and integrated photosensitive drum did not clear the ghosting, the drum is eliminated as the cause. A failing fuser roller that does not reach proper fusing temperature or has damaged coating will pick up toner particles and transfer them onto the paper with each rotation, causing persistent ghost images.

Step-by-Step Solution

1
Analyze the symptom and previous troubleshooting actions.
The issue is ghosting (repeated image defects). Replacing the toner cartridge and photosensitive drum did not resolve the issue.
Since drum-based ghosting was ruled out by component replacement, the defect must originate downstream in the electrophotographic process.
2
Evaluate remaining electrophotographic components responsible for heat and pressure.
The fuser assembly operates at high temperatures to permanently melt toner particles into paper fibers.
If the fuser heating element fails to maintain proper temperature, or if toner builds up on the fuser roller, un-fused toner transfers back onto the paper surface during subsequent roller rotations.
3
Identify the primary root cause.
Fuser roller assembly failure.
This is the primary electrophotographic component that causes repeating defects when drum replacement does not clear ghosting.

A desktop technician is troubleshooting a developer workstation that unexpectedly powers off during intensive CPU compilation tasks. When attempting to turn the system back on immediately following a shutdown, the cooling fans pulse for less than one second and immediately shut off, accompanied by an audible click from the power supply unit. The system only attempts to power on again after the main AC power cord is unplugged for 30 seconds and reconnected. Which of the following represent the most probable root causes or recommended diagnostic steps for this issue? (Select TWO.)

Select all that apply

Show answer & explanation

Answer: The power supply unit (PSU) internal safety circuit is latching into a protection fault state due to an over-current or over-temperature condition under heavy load.; Inspect the CPU heat sink assembly, verify fan operation, and reapply thermal compound to resolve CPU thermal trip conditions.

Answer

The issues are caused by the power supply unit latching its internal protection circuit due to a thermal or electrical fault, requiring AC power disconnection to reset, and the appropriate corrective action is to inspect the CPU cooling assembly and reapply thermal compound.
When a power supply unit detects an over-current or severe over-temperature event, internal protection logic trips and latches off to prevent catastrophic damage. This latching state prevents restart until AC power is completely disconnected. Because shutdowns occur specifically under heavy CPU compilation tasks, inspecting the CPU cooling assembly, thermal paste application, and fan operation addresses the underlying thermal failure triggering the PSU protection circuit.

Step-by-Step Solution

1
Analyze the symptom of momentary fan movement followed by immediate power-off with a PSU click, requiring AC power disconnection to retry.
Identify that the PSU internal protection circuit (OCP/OTP) has latched off to prevent component damage.
Latching safety circuits in modern PSUs mandate total removal of AC voltage to clear the fault latch.
2
Correlate the failure trigger with heavy CPU compilation workloads.
Recognize that CPU overheating or excess current draw under heavy processing load causes thermal/electrical protection trips.
Thermal interface breakdown or cooling failure leads to rapid thermal buildup during high CPU utilization.
3
Formulate appropriate physical diagnostic and remedial steps.
Inspect CPU heatsink seating, fan operation, and thermal compound integrity.
Restoring effective thermal dissipation prevents the CPU/VRM from exceeding thermal thresholds under load.

The issue occurs only when running demanding graphics applications and resolves after the system cools down. Which of the following is the most likely cause of this display issue?

Show answer & explanation

Answer: Overheating graphics processor or video RAM (VRAM)

Answer

Overheating graphics processor or video RAM (VRAM)
Visual artifacts such as multicolored dots, screen tearing, or distorted geometry that appear specifically under heavy 3D rendering load and disappear once the system cools down are a classic sign of an overheating graphics processor (GPU) or Video RAM (VRAM).

Step-by-Step Solution

1
Analyze the reported display symptoms and environment.
Visual artifacts (multicolored dots, distorted geometry) occur specifically during high graphical processing and clear up after the system cools down.
Connecting symptoms to thermal load points directly to physical hardware temperature issues.
2
Identify the hardware components responsible for rendering graphics under load.
The Graphics Processing Unit (GPU) and Video RAM (VRAM) process frame data and high-demand 3D rendering.
When GPU VRAM overheats under stress, frame data becomes corrupted prior to display output.
3
Select the primary cause matching the thermal symptom profile.
Overheating graphics processor or video RAM (VRAM) is the correct diagnosis.
Thermal stress on video memory creates random visual artifacts that disappear once temperatures lower.

Show answer & explanation

Answer

Incoming Remote Desktop host and Domain Join match Windows Pro Edition; AppLocker and BranchCache match Windows Enterprise Edition; 4 physical CPUs and NVDIMM-N support match Windows Pro for Workstations Edition; single physical CPU without domain support matches Windows Home Edition.
Each feature requirement maps accurately to the Windows edition feature matrix: Windows Pro provides domain join and incoming Remote Desktop hosting; Windows Enterprise adds advanced governance like AppLocker and BranchCache; Windows Pro for Workstations enables high-end hardware features like 4 physical CPUs and NVDIMM-N; and Windows Home handles basic consumer tasks limited to 1 physical CPU.

Step-by-Step Solution

1
Identify core business management features
Domain Join and Remote Desktop hosting require at least Windows Pro Edition.
Windows Home Edition lacks native Remote Desktop hosting and domain membership capabilities.
2
Identify enterprise-exclusive policy tools
AppLocker and BranchCache require Windows Enterprise Edition.
These features are restricted to volume-licensed enterprise editions.
3
Identify high-performance hardware architecture requirements
NVDIMM-N and 4 physical CPU support require Windows Pro for Workstations Edition.
Standard Pro is capped at 2 physical CPUs, whereas Pro for Workstations supports up to 4 CPUs and persistent memory.
4
Identify entry-level consumer edition capabilities
Single physical CPU support with no domain capabilities maps to Windows Home Edition.
Windows Home is intended for standalone consumer use without corporate management infrastructure.
