During a network audit, an administrator inspects a server configured with the static IPv4 address $172.20.12.85/22$ (subnet mask $255.255.252.0$ ). The host can successfully communicate with local devices on its subnet but cannot reach any external networks. Command output confirms the default gateway is set to $172.20.16.1$ and the DNS server is set to $172.20.12.2$ .

Which of the following statements correctly explain the root cause of the routing failure and how to resolve it? (Select TWO.)

Geçerli olan tümünü seçin

The configured default gateway resides outside the server's valid local subnet range of

172.20.12.1

through

172.20.15.254

The DNS server address must be updated to

172.20.16.1

because DNS services can only be hosted on the router designated as the default gateway.

The default gateway must be reconfigured to an IP address within the

172.20.12.0/22

network address space.

The server must be reconfigured to automatically request an APIPA address starting with

169.254

to enable routing to remote subnets.

Cevap: The configured default gateway resides outside the server's valid local subnet range of $172.20.12.1$ through $172.20.15.254$ .; The default gateway must be reconfigured to an IP address within the $172.20.12.0/22$ network address space.

Cevap

The default gateway is misconfigured on a different subnet outside the local range of

172.20.12.1

172.20.15.254

, and it must be changed to an IP address within the local

172.20.12.0/22

network space.

With a CIDR notation of /22 (

255.255.252.0

), the network block size in the third octet is 4. The subnet housing host

172.20.12.85

starts at

172.20.12.0

and ends at broadcast address

172.20.15.255

, making the valid host range

172.20.12.1

through

172.20.15.254

. The configured gateway

172.20.16.1

is on a separate subnet. A default gateway must reside on the local subnet to process off-subnet packets.

Adım Adım Çözüm

Calculate the subnet boundary for

172.20.12.85/22

A /22 prefix corresponds to

255.255.252.0

. The block size in the third octet is

256 - 252 = 4

. Subnet ranges increment by 4 starting from 0:

0-3

4-7

8-11

12-15

. Thus, the local subnet is

172.20.12.0/22

, spanning usable host IPs from

172.20.12.1

172.20.15.254

Determining the network boundary reveals which IP addresses are local to the server.

Evaluate the current default gateway address (

172.20.16.1

The gateway

172.20.16.1

belongs to the adjacent network (

172.20.16.0/22

) and is not on the local

172.20.12.0/22

subnet.

A host cannot communicate directly with a default gateway that does not share its local layer 3 subnet.

Identify the required corrective configuration.

The default gateway must be updated to a valid router interface IP located within the local

172.20.12.0/22

network.

This allows the host to direct off-subnet traffic to its local router interface for forwarding.

Cevap: The delicate spring-loaded contact pins are located inside the motherboard socket rather than on the CPU package.; Thermal interface material must be applied between the processor integrated heat spreader (IHS) and the heatsink base to bridge microscopic air gaps.

Cevap

Land Grid Array (LGA) sockets feature pins positioned on the motherboard socket, and thermal compound must be applied between the CPU integrated heat spreader (IHS) and the heatsink base to fill microscopic air voids.

In Land Grid Array (LGA) sockets, the delicate contact pins are located on the motherboard socket itself rather than on the CPU. Additionally, thermal interface material (TIM) is essential to fill microscopic gaps between the processor's integrated heat spreader (IHS) and the heatsink base to facilitate effective conductive heat transfer.

Adım Adım Çözüm

Identify the pin architecture of Land Grid Array (LGA) sockets.

Confirm that LGA socket designs feature pins built into the socket on the motherboard, whereas the CPU has corresponding flat contact pads.

This distinguishes LGA architecture from PGA (Pin Grid Array) architecture, which places pins directly on the processor.

Determine thermal cooling installation requirements.

Recognize that metal surfaces on the CPU IHS and heatsink base are imperfect at a microscopic level, creating thermal insulating air pockets.

Cevap: The USB Type-C cable being used only supports USB 2.0 data and power delivery, lacking support for DisplayPort Alternate Mode.

Cevap

The cable being used only supports power delivery and USB 2.0 data, lacking support for DisplayPort Alternate Mode.

USB Type-C ports use DisplayPort Alternate Mode to output video signals to external displays. This functionality requires a USB-C cable that contains internal high-speed data lanes. Standard power/charging cables frequently include only power conductors and basic USB 2.0 data lines, preventing video signals from reaching the display.

Adım Adım Çözüm

Analyze reported symptoms and hardware behavior

Power is transmitted successfully over the cable, but video signaling fails.

Charging success verifies physical connection and power pin continuity, isolating the issue to data lane capability.

Evaluate USB Type-C feature support requirements

Video transfer over USB Type-C depends on DisplayPort Alternate Mode (Alt Mode), which requires specific internal high-speed data wiring within the cable.

Many standard charging cables omit high-speed video lanes to keep manufacturing costs lower.

Determine corrective resolution

Replacing the current cable with a fully featured USB Type-C cable rated for DisplayPort Alt Mode will allow video output.

A fully featured cable provides the necessary physical pin lanes for Alt Mode negotiation.

Cevap: The dedicated 8-pin EPS12V CPU power cable was not connected to the motherboard.

Cevap

The dedicated 8-pin EPS12V CPU power cable was not connected to the motherboard.

Modern motherboards require both the 24-pin ATX main power connector and an auxiliary 4-pin or 8-pin EPS12V connector. The 24-pin ATX connector provides standby power (+5VSB) and basic logic power, which illuminates onboard LEDs. However, the dedicated 8-pin EPS12V cable supplies the high amperage +12V power needed by the processor. Omitting the EPS12V connection prevents the CPU from powering on and halts the system power cycle.

Adım Adım Çözüm

Analyze system power flow and symptoms

Motherboard standby LED is lit (indicating 5VSB power from 24-pin ATX is active), but system will not turn on or POST when power button is pressed.

Main 24-pin ATX delivers standby voltage and basic motherboard logic power, but modern multi-core processors require auxiliary dedicated +12V power.

Identify missing power delivery component

The 8-pin EPS12V (or 4+4 pin) power cable provides direct power to the CPU voltage regulator.

If the EPS12V connector is omitted, the CPU lacks operational power, causing the system power-on sequence to halt immediately.

To avoid co-channel and adjacent-channel interference, which channel should the technician assign to the new access point?

Channel 11

Channel 3

Channel 5

Channel 8

Cevabı ve açıklamayı göster

Cevap: Channel 11

Cevap

Channel 11 should be assigned to the access point because it is the remaining standard non-overlapping channel in the 2.4 GHz frequency band when channels 1 and 6 are already in use.

In 2.4 GHz Wi-Fi standards, individual 20 MHz channels require 25 MHz of separation to avoid overlapping. Consequently, channels 1, 6, and 11 are designated as the standard non-overlapping channels. Because the surrounding access points are operating on channels 1 and 6, selecting Channel 11 guarantees zero spectral overlap and avoids interference.

Adım Adım Çözüm

Identify the standard non-overlapping channels in the 2.4 GHz Wi-Fi spectrum.

In North American 2.4 GHz 802.11 deployments, channels 1, 6, and 11 are the three non-overlapping 20 MHz channels.

Each 20 MHz channel spans a 22 MHz channel width spaced 5 MHz apart, requiring a 5-channel separation to prevent spectral overlap.

Evaluate the channel usage reported by the site survey.

Neighboring access points are occupying Channel 1 and Channel 6.

Choosing any channel between 1 and 10 will create adjacent-channel interference with at least one active neighboring network.

Select the channel that eliminates interference.

Select Channel 11.

Channel 11 operates centered at 2462 MHz, providing full clearance from Channel 1 (2412 MHz) and Channel 6 (2437 MHz).

Cevabı ve açıklamayı göster

Cevap: eSATA cable with a maximum length of 2 meters

Cevap

An eSATA cable with a maximum standard length of 2 meters provides native SATA storage connectivity for external drive enclosures.

The eSATA (External Serial ATA) standard uses a specially shielded 7-pin connector designed to withstand insertion wear and provide extra protection against electromagnetic interference (EMI). Unlike internal SATA cables (which are restricted to

1\text{ m}

), eSATA supports cable runs up to

2\text{ m}

while maintaining direct 6 Gbps bus transfer speeds without protocol bridging.

Adım Adım Çözüm

Identify the required peripheral protocol and connector type based on specifications.

The requirement specifies native SATA 6 Gbps connectivity to an external 7-pin shielded peripheral port, matching the eSATA specification.

eSATA provides a dedicated external physical interface with extra shielding and insertion retention mechanisms specifically designed for external SATA storage enclosures.

Verify maximum cable length standards for the selected cable type.

The maximum recommended cable length for eSATA is 2 meters (

2\text{ m}

), compared to 1 meter (

1\text{ m}

) for internal SATA data ribbon cables.

eSATA specifications allow slightly higher voltage transmit levels and improved receiver sensitivity to support longer shielded cable runs up to 2 meters.

A field technician is upgrading a desktop workstation by installing a newly purchased M.2 SATA SSD into an available expansion slot on the motherboard. According to the motherboard technical manual, this specific slot is wired exclusively to communicate over PCIe x4 lanes. Upon powering on the workstation and entering the UEFI setup utility, the technician observes that the new M.2 drive is not recognized by the system. Which of the following best explains why the drive is not detected?

The M.2 slot is wired strictly to the PCIe bus and lacks a SATA controller link, preventing communication with an M.2 SATA drive.

The motherboard's primary storage controller mode must be reconfigured from AHCI mode to NVMe mode in UEFI settings to detect SATA drives.

The M.2 SATA solid-state drive requires a dedicated 15-pin SATA power cable attached from the power supply unit to function.

The installed drive cannot be enumerated in UEFI until operating system-level NVMe host controller drivers are loaded.

Cevap: The M.2 slot is wired strictly to the PCIe bus and lacks a SATA controller link, preventing communication with an M.2 SATA drive.

Cevap

The M.2 slot is wired strictly to the PCIe bus and lacks a SATA controller link, preventing communication with an M.2 SATA drive.

Although M.2 defines a standardized physical form factor, motherboard M.2 slots vary in their underlying bus connections. A slot that is wired exclusively to PCIe x4 lanes cannot communicate with a drive that operates on the SATA protocol. Because the slot lacks a physical link to a SATA controller, the UEFI firmware cannot detect or enumerate the M.2 SATA drive.

Adım Adım Çözüm

Analyze the physical and protocol constraints of the storage drive and motherboard slot.

The installed drive uses the SATA transfer protocol, whereas the motherboard M.2 slot is wired exclusively with PCIe x4 lanes.

M.2 is a physical form factor that can route either SATA or PCIe bus signaling depending on motherboard slot wiring.

Determine the compatibility requirement for M.2 SATA drives.

For an M.2 slot to support a SATA SSD, the slot must be routed to a motherboard SATA controller or support dual-mode (SATA/PCIe) operation.

If an M.2 slot is PCIe-only, a SATA drive inserted into it will not establish a data link.

Identify the cause of the detection failure.

The absence of SATA signal routing on the PCIe-only slot prevents the UEFI firmware from recognizing the SATA SSD.

Protocol mismatch between drive type and slot wiring causes total detection failure.

A network administrator is setting up a new network printer to be shared through a central Windows print server. Place the configuration steps in the correct logical sequence from first to last.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct order to deploy a network print share is: 1) Assign a static IP address to the printer, 2) Add a TCP/IP port and install the driver on the print server, 3) Enable printer sharing and permissions on the server, and 4) Map the shared printer on client workstations.

The correct setup sequence begins with assigning a static IP address directly to the printer to ensure consistent communication. Next, the server is configured with a standard TCP/IP port and appropriate printer driver. After the local print queue functions on the server, sharing and access permissions are configured. Finally, client computers are connected to the network print share.

Adım Adım Çözüm

Configure the physical printer with a static IP address.

The printer maintains a constant network location.

Print servers require a fixed IP address to prevent print queue failure due to DHCP address changes.

Create the print queue on the print server using a standard TCP/IP port and the vendor driver.

The print server establishes communication with the printer.

The print server must communicate with the hardware before it can broadcast a share queue to the network.

Turn on network sharing for the print queue and set permission controls.

The print queue is advertised and accessible over the network.

Sharing exposes the queue to authorized clients across the subnet.

Connect client computers to the server's shared print queue.

Users can successfully submit jobs to the network printer.

Clients send print jobs to the print server share only after the share is operational.

Cevap: Replace the existing cable with a certified 40 Gbps Thunderbolt 4 / USB4 cable supporting DisplayPort 1.4 HBR3 Alternate Mode.

Cevap

Replace the existing cable with a certified 40 Gbps Thunderbolt 4 / USB4 cable supporting DisplayPort 1.4 HBR3 Alternate Mode.

DisplayPort Alternate Mode over USB Type-C relies on high-speed differential pairs within the cable. To drive a

4\text{K}

display at

120\text{ Hz}

alongside USB data passthrough, high bit rate 3 (HBR3) bandwidth is required. Replacing the basic 5 Gbps USB 3.2 cable with a certified 40 Gbps Thunderbolt 4 / USB4 cable provides full physical wire populating and shielding required to transmit uncompressed

4\text{K}

video at

120\text{ Hz}

while preserving USB peripheral throughput.

Adım Adım Çözüm

Analyze resolution and bandwidth requirements

A resolution of

3840 \times 2160

(

4\text{K}

) at

120\text{ Hz}

with

10\text{-bit}

HDR color depth requires approximately 25.8 Gbps of uncompressed video bandwidth (HBR3 rating).

Standard USB 3.2 Gen 1 cables are limited to 5 Gbps and lack the high-speed lane wiring required for high-refresh

4\text{K}

video signals alongside data.

Evaluate USB Type-C physical connector vs. protocol capabilities

Physical USB Type-C cables vary significantly in internal pin populating and shielding, affecting supported protocols (DisplayPort Alt Mode vs. basic USB data).

To support both high-bitrate video (HBR3) and high-speed peripheral data over a single port, a cable certified for 40 Gbps (Thunderbolt 4 / USB4) is required.

Select the appropriate replacement cable

The certified 40 Gbps Thunderbolt 4 / USB4 cable supports full DisplayPort 1.4 Alt Mode bandwidth without compromising attached USB hub data transfer rates.

This cable meets all video bandwidth, refresh rate, and multi-stream data requirements.

A systems engineer is assembling a high-performance workstation featuring a high-end CPU ( $125\text{ W}$ TDP), a flagship discrete GPU with a peak power draw of $450\text{ W}$ , multiple NVMe drives ( $30\text{ W}$ combined), and liquid cooling pumps with fans ( $45\text{ W}$ combined). The system is currently equipped with a $650\text{ W}$ power supply unit (PSU). Under full benchmarking load, the workstation instantly shuts off without generating any operating system crash logs or blue screen errors. Which of the following statements correctly explain the root cause of these shutdowns and identify the necessary power infrastructure requirements for stable operation? (Select TWO.)

Geçerli olan tümünü seçin

The existing power supply fails to provide adequate wattage headroom to support the combined continuous component power budget and transient GPU peak power excursions, requiring a replacement rated for at least

850\text{ W}

The graphics card must receive dedicated auxiliary power connections via individual

+12\text{ V}

cable runs from the PSU rather than a single daisy-chained cable split across multiple headers.

The motherboard PCIe x16 expansion slot is defective because it fails to supply the required

450\text{ W}

of auxiliary power directly through the motherboard bus pins.

The system motherboard requires an upgraded EPS12V CPU power connector configured to auto-negotiate wattage draw with the expansion bus during heavy processing workloads.

Cevap: The existing power supply fails to provide adequate wattage headroom to support the combined continuous component power budget and transient GPU peak power excursions, requiring a replacement rated for at least $850\text{ W}$ .; The graphics card must receive dedicated auxiliary power connections via individual $+12\text{ V}$ cable runs from the PSU rather than a single daisy-chained cable split across multiple headers.

Cevap

Stable operation requires replacing the power supply with a unit rated for at least

850\text{ W}

to accommodate baseline draws and GPU transient spikes, alongside powering the graphics card using independent, non-daisy-chained auxiliary

+12\text{ V}

power cables directly from the PSU.

The correct selections recognize both the quantitative wattage deficit and the physical power delivery cabling requirements. The baseline load of

650\text{ W}

leaves zero margin for efficiency loss or transient GPU power spikes on a

650\text{ W}

PSU, requiring an upgrade to an

850\text{ W}

or higher unit. Additionally, high-wattage graphics cards require independent PCIe auxiliary power cables connected directly to dedicated PSU outlets to prevent overcurrent cable failure and trips.

Adım Adım Çözüm

Calculate the continuous power baseline of the workstation components.

Sum of component power draws:

125\text{ W (CPU)} + 450\text{ W (GPU)} + 30\text{ W (Storage)} + 45\text{ W (Cooling)} = 650\text{ W}

Establishing total continuous power consumption establishes the minimum theoretical load.

Apply standard industry sizing headroom (

20\%\text{--}30\%

) for efficiency and transient GPU power excursions.

650\text{ W} \times 1.25 \approx 812.5\text{ W}

, indicating a minimum recommended PSU rating of

850\text{ W}

Modern GPUs exhibit momentary power spikes above their rated TBP, triggering Over-Power Protection (OPP) on un-headroomed power supplies.

Evaluate GPU auxiliary power delivery requirements.

Since PCIe slots only provide up to

75\text{ W}

, the remaining

375\text{ W}+

must come from multiple independent PCIe 8-pin or 12VHPWR/12V-2x6 cables running from distinct PSU terminals.

Using daisy-chained splitters on a single cable trunk exceeds safe current limits per gauge wire, triggering Over-Current Protection (OCP) or overheating.

Cevap: Secure print with PIN or badge authentication

Cevap

Secure print with PIN or badge authentication

Enabling secure print or PIN-based print release ensures that jobs are held in print memory until the initiating user authenticates in person at the multifunction device, preventing sensitive paper outputs from sitting unattended in the tray.

Adım Adım Çözüm

Identify the security requirement described in the scenario.

The requirement mandates preventing confidential documents from remaining unattended on the paper output tray.

Security and compliance rules require physical privacy at the point of document output.

Evaluate printer configuration features for document release controls.

Secure print (also known as hold print or passcode print) stores the print job securely until the user walks to the MFD and authenticates at the control panel.

This guarantees the user is physically present at the device when pages are extruded into the tray.

A computer technician is sizing a replacement power supply for a desktop computer. The graphics card consumes $300\text{ W}$ at peak load, and all other internal components combined consume $200\text{ W}$ . To maintain system stability, the power supply must provide an additional $20\%$ power headroom above the total peak power draw. What is the minimum power supply wattage required?

600\text{ W}

500\text{ W}

360\text{ W}

300\text{ W}

Cevabı ve açıklamayı göster

Cevap: $600\text{ W}$

Cevap

The minimum power supply wattage required for the system is

600\text{ W}

The total base power consumption of the system is

300\text{ W} + 200\text{ W} = 500\text{ W}

. Including the required

20\%

safety margin (

500\text{ W} \times 0.20 = 100\text{ W}

) increases the minimum total requirement to

600\text{ W}

Adım Adım Çözüm

Calculate the total base power consumption of all internal components.

300\text{ W} + 200\text{ W} = 500\text{ W}

All hardware components draw power concurrently during peak load.

Calculate the required

20\%

safety overhead.

500\text{ W} \times 0.20 = 100\text{ W}

Providing power headroom prevents system instability and component degradation.

Sum the total base power draw and the safety headroom margin.

500\text{ W} + 100\text{ W} = 600\text{ W}

This total establishes the minimum rated wattage required for the power supply unit.
