A field technician is dispatched to a corporate conference room where a newly installed ceiling-mounted projector is experiencing intermittent video degradation. The presenter's laptop is connected to the projector using a 50-foot (15-meter) passive HDMI cable run through the wall. When transmitting a 1080p video signal at 60Hz, the image displays normally. However, whenever the laptop resolution is increased to native 4K at 60Hz to display detailed engineering schematics, the projected image experiences digital noise ('sparkles'), brief black screens, and periodic loss of signal sync. Lowering the resolution back to 1080p immediately stabilizes the display. Which of the following is the most appropriate action for the technician to take to resolve this issue?

Cevabı ve açıklamayı göster

Cevap: Replace the passive cable with an active HDMI cable or an HDMI-over-Ethernet extender system

Cevap

Replace the long passive HDMI cable with an active HDMI cable or an optical/Ethernet extender system designed for long-distance 4K video transmission.
Passive HDMI cables suffer from high-frequency attenuation over long distances (typically over 15 feet). While lower-bandwidth signals like 1080p can pass successfully, higher-bandwidth signals like 4K@60Hz experience bit errors manifesting as digital sparkles, sync drops, and black screens. Resolving this requires active signal regeneration via an active HDMI cable, fiber-optic HDMI, or an HDBaseT extender.

Adım Adım Çözüm

1
Analyze the symptoms across different resolution settings
The video signal operates stably at 1080p (lower bandwidth demand: ~4.95 Gbps) but fails with signal dropped frames and digital noise at 4K@60Hz (higher bandwidth demand: ~18 Gbps).
Determines whether the issue is related to video bandwidth capacity and signal attenuation over distance.
2
Evaluate physical layer transmission constraints
Standard passive HDMI cables experience significant signal degradation (attenuation) over distances exceeding 15 feet (5 meters) when attempting to carry high-frequency 4K signals.
Long passive cable runs cannot maintain digital signal integrity for high-bandwidth HDMI specifications without active boosting.
3
Select the correct corrective hardware action
Installing an active HDMI cable (which includes embedded signal-boosting chipsets) or an HDMI over HDBaseT/Cat6 extender kit restores clean signal transmission at 4K resolution.
Provides the necessary signal amplification to overcome insertion loss across long physical distances.

Cevap: An M.2 solid-state drive featuring an M-key edge connector will physically fit into Slot 1 and operate using the NVMe protocol.; Installing a PCIe NVMe-only M.2 drive into Slot 2 will result in the drive failing to be recognized by the motherboard host controller.

Cevap

An M.2 solid-state drive featuring an M-key edge connector will physically fit into Slot 1 and operate using the NVMe protocol, and installing a PCIe NVMe-only M.2 drive into Slot 2 will result in the drive failing to be recognized by the motherboard host controller.
The M-keyed Slot 1 provides four PCIe lanes required for NVMe solid-state drives. Conversely, Slot 2 is wired directly to the SATA bus; inserting a PCIe-only NVMe drive into a SATA-only slot prevents communication between the drive and host controller, leaving the drive undetected.

Adım Adım Çözüm

1
Evaluate physical keying and bus support for Slot 1.
Slot 1 utilizes M-keying and PCIe 4.0 x4 lanes, which natively supports NVMe storage drives.
M-key M.2 slots supply four PCIe lanes, matching the interface specifications for high-performance NVMe SSDs.
2
Evaluate protocol and bus compatibility for Slot 2.
Slot 2 is B-keyed and routed only to SATA lines, preventing NVMe PCIe drives from being detected.
An M.2 slot wired solely to a SATA host controller cannot negotiate PCIe data signals needed by an NVMe drive.

To ensure system stability during peak load events and prevent PSU safety shutdowns, the organization requires that total peak system power draw does not exceed 80%80\% of the PSU's maximum rated capacity. Which of the following is the minimum PSU wattage rating required for this workstation?

Cevabı ve açıklamayı göster

Cevap: 1000 W1000\text{ W}

Cevap

The minimum power supply rating required is 1000 W1000\text{ W}.
The option specifying 1000 W1000\text{ W} correctly calculates total maximum power consumption by summing all component peak draws (250 W+420 W+25 W+65 W+40 W=800 W250\text{ W} + 420\text{ W} + 25\text{ W} + 65\text{ W} + 40\text{ W} = 800\text{ W}) and dividing by 0.800.80 to enforce the required 20%20\% safety overhead margin (800 W/0.80=1000 W800\text{ W} / 0.80 = 1000\text{ W}).

Adım Adım Çözüm

1
Calculate the total peak system power draw under maximum load
250 W (CPU peak)+420 W (GPU peak)+25 W (PCIe card)+65 W (Motherboard/RAM/SSD)+40 W (Cooling/Fans)=800 W250\text{ W (CPU peak)} + 420\text{ W (GPU peak)} + 25\text{ W (PCIe card)} + 65\text{ W (Motherboard/RAM/SSD)} + 40\text{ W (Cooling/Fans)} = 800\text{ W}
Sizing a power supply for high-performance workstations requires planning for full transient peak power excursions rather than static TDP values.
2
Apply the 80%80\% maximum continuous load limit requirement to find required PSU capacity
Required Capacity=800 W0.80=1000 W\text{Required Capacity} = \frac{800\text{ W}}{0.80} = 1000\text{ W}
To maintain system stability, operate near peak PSU efficiency curve, and prevent over-current protection (OCP) tripping during power surges, the peak system draw must not exceed 80%80\% of the PSU's total capacity.

Cevap

Category 6a (Cat 6a) UTP matches 10 Gbps Ethernet up to 100 meters; Thunderbolt 4 matches 40 Gbps throughput with mandatory dual 4K display support; Single-mode Fiber (SMF) matches narrow 8.3–10 micron core for laser transmission; USB 3.2 Gen 2x1 matches 10 Gbps transfer rate.
Category 6a (Cat 6a) supports 10 Gbps Ethernet up to 100 meters. Thunderbolt 4 provides 40 Gbps throughput and mandates support for two 4K displays. Single-mode Fiber uses a small 8.3–10 micron core with lasers for long distances. USB 3.2 Gen 2x1 supports up to 10 Gbps throughput over a single lane.

Adım Adım Çözüm

1
Analyze twisted-pair copper ethernet standards for bandwidth and distance capabilities.
Identify Category 6a as supporting 10 Gbps up to 100 meters (unlike standard Cat 6, which is limited to 55 meters at 10 Gbps).
Cat 6a extends 10GBASE-T performance across full structured cabling distances.
2
Evaluate high-speed peripheral standards and display capabilities.
Identify Thunderbolt 4 as offering 40 Gbps speed with mandatory dual 4K video display output.
Thunderbolt 4 strict certifications require dual 4K or single 8K DisplayPort Alt Mode capabilities alongside 40 Gbps data.
3
Differentiate optical fiber types by core size and light source.
Identify Single-mode Fiber by its 8.3–10 micron core diameter and laser light propagation.
Multi-mode fiber uses larger cores (50 or 62.5 microns) and LEDs, whereas Single-mode uses small cores and lasers for long distance.
4
Identify USB throughput standards.
Map USB 3.2 Gen 2x1 to its 10 Gbps maximum transfer speed specification.
USB 3.2 Gen 2x1 is a single-lane 10 Gbps bus specification available on both Type-A and Type-C physical connectors.

Cevap: Inspect and replace the wiper blade or drum cleaning assembly on the laser printer.; Clean the heating element of the thermal printhead using isopropyl alcohol and a lint-free swab.

Cevap

The technician should replace the wiper blade/drum cleaning assembly on the laser printer and clean the thermal printhead heating elements using high-purity isopropyl alcohol and a lint-free swab.
Replacing the wiper blade (or drum unit) addresses ghosting because the cleaning phase of electrophotographic printing requires physical removal of excess toner from the photosensitive drum before exposure. Cleaning the thermal printhead with isopropyl alcohol removes burnt wax/resin buildup from heating elements, restoring uniform heat transfer and crisp output.

Adım Adım Çözüm

1
Analyze the laser printer ghosting symptom.
Identified that ghost images stem from incomplete removal of residual toner during the EP cleaning step.
The wiper blade physical wear permits residual charges/toner to cycle back around to the developing and conditioning phases.
2
Determine the appropriate repair for the laser printer.
Replacing the wiper blade or integrated drum unit clears the physical drum surface cleanly.
A worn cleaning blade fails to strip un-transferred toner prior to electrostatic recharging.
3
Analyze the thermal transfer printer symptom.
Recognized that faint/streaked print output is caused by thermal printhead accumulation or residue.
Burnt wax/resin build-up prevents clean heat transfer from the thermal pins to the ribbon.
4
Determine the appropriate maintenance for the thermal printer.
Cleaning the printhead with 99% isopropyl alcohol removes thermal residue without damaging delicate heating elements.
Isopropyl alcohol dissolves wax/resin deposits safely and evaporates cleanly.

A network technician is optimizing a 2.4 GHz wireless deployment in a corporate warehouse where handheld mobile inventory scanners frequently drop network connections. A site survey reveals that neighboring access points are broadcasting on channels 2, 3, and 4, resulting in severe performance degradation. Which of the following channel configurations should the technician implement on the access points to eliminate wireless channel overlap?

Cevabı ve açıklamayı göster

Cevap: Reconfigure the access points to use non-overlapping channels 1, 6, and 11.

Cevap

Reconfigure the access points to use non-overlapping channels 1, 6, and 11.
Configuring 2.4 GHz access points to use channels 1, 6, and 11 prevents adjacent-channel interference. In standard 2.4 GHz Wi-Fi networks, these three channels are the only non-overlapping channel combination available in North America and many standard regulatory domains.

Adım Adım Çözüm

1
Analyze the frequency characteristics of the 2.4 GHz wireless spectrum.
The 2.4 GHz band consists of 11 to 14 channels, each 22 MHz wide, spaced 5 MHz apart.
Because channels overlap with adjacent channels, operating on neighboring channels causes radio frequency interference.
2
Identify the standard non-overlapping channels for 2.4 GHz Wi-Fi deployments.
Channels 1, 6, and 11 have sufficient channel separation to prevent co-channel and adjacent-channel interference.
Using 1, 6, and 11 allows multiple access points to provide seamless coverage without interfering with one another.
