Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The technician must first power off the printer and let the fuser cool, replace the fuser, transfer roller, and pickup rollers, reconnect power and turn the printer back on, and finally reset the printer maintenance page counter in the management menu.
The correct sequence prioritizes technician safety by disconnecting power and cooling the fuser first. Hardware parts (fuser, transfer roller, pickup rollers) are replaced next. Restoring power allows the printer to complete its self-test, after which the administrative maintenance counter can be reset to clear the prompt and begin a new maintenance tracking cycle.

Adım Adım Çözüm

1
Power off and disconnect the printer, allowing the fuser to cool down.
Electrical safety is ensured and burn risks from the fuser (which operates near 400°F/200°C) are eliminated.
CompTIA safety guidelines dictate removing power sources and mitigating thermal hazards prior to opening internal assemblies.
2
Swap out the old maintenance kit parts (fuser assembly, transfer roller, pickup/feed rollers) for new ones.
Worn mechanical components are replaced with fresh hardware.
Physical component replacement must occur while the device is unpowered and cool.
3
Reconnect power and turn the printer back on.
The printer conducts its initial POST (Power-On Self-Test) and enters a ready state.
The system must be online to access administrative menus and verify mechanical operation.
4
Navigate to the control panel settings menu to reset the maintenance counter.
The warning message clears and the internal cycle counter resets to zero.
The printer cannot automatically detect mechanical part replacement; manual counter reset is required to track the next maintenance cycle accurately.

A desktop technician is upgrading a workstation by installing a dedicated PCIe x16 graphics card with a peak draw of 220 W220\text{ W} and a PCIe x4 multi-port capture card rated at 20 W20\text{ W}. The host CPU requires 105 W105\text{ W}, while remaining peripherals consume 45 W45\text{ W}. Which of the following technical precautions and installation requirements must be met to ensure hardware compatibility and stable power delivery? (Select TWO.)

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Auxiliary power to the graphics card must be supplied using dedicated PCIe power cables rather than EPS12V cables.; The total sustained output on the +12V rail must accommodate peak system draw plus a safety headroom margin.

Cevap

The technician must ensure auxiliary power to the graphics card uses dedicated PCIe power cables (not EPS12V) and verify that the power supply's +12V rail provides adequate capacity including a safety headroom margin.
Dedicated high-draw graphics cards require auxiliary PCIe power cables, as EPS12V connectors carry a different pinout intended for CPU sockets. Additionally, PSUs must be selected with sufficient +12V output capacity and safety headroom above the aggregate peak consumption to guarantee stable operations.

Adım Adım Çözüm

1
Calculate component power demands and continuous headroom requirements
Total peak consumption is 220 W+20 W+105 W+45 W=390 W220\text{ W} + 20\text{ W} + 105\text{ W} + 45\text{ W} = 390\text{ W}. A power supply must provide continuous capacity above this value (typically 20%–30% overhead margin) primarily on the +12V rail.
Calculated total power draws require extra headroom to account for transient power spikes and capacitor degradation.
2
Identify correct PSU cable connectors for auxiliary card power
Use 6-pin or 8-pin (6+2 pin) PCIe power cables for the dedicated GPU.
Connecting EPS12V cables into GPU ports damages hardware due to reversed power and ground pin layout.
3
Verify PCIe slot backward/forward compatibility rules
PCIe x4 cards fit and function normally in PCIe x4, x8, or x16 slots.

A technician is setting up a desktop workstation for video editing. The motherboard features one primary PCIe x16 expansion slot wired electrically at x16 and a secondary full-length PCIe x16 expansion slot wired electrically at x4. The technician installs a dual-slot PCIe x16 graphics card in the primary slot. Which of the following components can be installed into the secondary expansion slot without encountering physical keying or mechanical fit issues?

Cevabı ve açıklamayı göster

Cevap: A PCIe x4 dedicated network interface card

Cevap

A PCIe x4 dedicated network interface card can be physically and operationally installed into the secondary full-length PCIe slot.
PCI Express expansion slots support backward physical compatibility. A card with fewer lanes (such as a PCIe x4 card) can be physically inserted into any larger mechanical slot (such as a x16 slot). Because the secondary slot is wired electrically for x4 speed, the x4 network card will function at its maximum rated bandwidth.

Adım Adım Çözüm

1
Analyze the physical and electrical specifications of the secondary slot.
The slot is mechanically a full-length PCIe x16 slot, but electrically wired for x4 lanes.
PCI Express standards support upward compatibility where smaller pin-count cards (x1, x4, x8) fit physically and function correctly inside larger mechanical slots.
2
Evaluate the candidate expansion cards against the slot dimensions and connector keying.
A PCIe x4 card fits cleanly into a full-length x16 slot and operates at full x4 speed.
Smaller PCIe cards leave unused pin pads in longer PCIe slots without affecting electrical operation.

Cevabı ve açıklamayı göster

Cevap: Overheating of the dedicated graphics card processor core during heavy workload; Failing or corrupted video RAM (VRAM) modules on the expansion card

Cevap

The most likely causes of load-specific visual artifacts are GPU thermal overheating and defective video RAM (VRAM) modules.
Visual artifacts such as random geometric shapes, tearing, and pixel discoloration occurring specifically under heavy graphical processing are classic symptoms of hardware-level GPU component failure. Specifically, GPU core overheating causes processing logic errors under thermal stress, and failing VRAM modules corrupt the frame buffer data stored on the graphics card.

Adım Adım Çözüm

1
Analyze the reported visual symptoms and workload dependency
Identified that visual artifacts (colored specks/tearing) occur exclusively during intensive GPU rendering tasks while static desktop applications display correctly.
Hardware rendering errors under stress indicate issues localized to the graphics processing subsystem rather than monitor backlighting or static screen panels.
2
Evaluate potential hardware failures in the graphics subsystem
Confirmed that excessive GPU core temperatures and faulty VRAM chips directly cause rendering memory corruption.
When GPU VRAM or the core processor overheats, binary frame data becomes corrupted in hardware buffer memory, manifesting as artifacts.

Identified as a private cloud or on-premises environment due to dedicated, self-managed local hardware.
Private deployment models reserve compute resources exclusively for one organization.
3
Synthesize the combined architecture
Combining public cloud resources with on-premises private infrastructure defines a hybrid cloud deployment.
Hybrid cloud explicitly bridges public and private/on-premises environments to leverage benefits from both.

A desktop technician is troubleshooting network performance issues reported by a user accessing a remote server across multiple routed subnets. The technician wants to identify which specific router hop along the path is introducing latency and packet loss by sending packets to each intermediate hop over a sampling period. Which Windows command-line utility should the technician use?

Cevabı ve açıklamayı göster

Cevap: pathping

Cevap

The pathping command should be used to trace the route and measure packet loss per router hop.
The pathping utility is specifically designed to combine the functionality of ping and tracert. It traces the route to the target IP address and then pings each intermediate router over a test period to compute latency and packet loss statistics for every hop along the path.

Adım Adım Çözüm

1
Analyze the requirement for identifying packet loss and latency at intermediate network hops over a sample interval.
Recognize that a hybrid tool combining route tracing with statistics collection is required.
Standard ICMP pinging tests only the end destination, while tracert tests path latency at a single instant without long-term packet loss statistics.
2
Select the appropriate native Windows command-line diagnostic tool.
Identify pathping as the tool designed to ping intermediate routers over a time interval.
pathping sends multiple pings to each hop along the route to generate comprehensive latency and packet loss statistics per router node.
