A computer technician is assembling a desktop workstation and connecting cables from the power supply unit (PSU) to the motherboard. After successfully connecting the 24-pin ATX main power connector, the technician needs to provide dedicated auxiliary power to the processor socket. Which of the following power connectors should be plugged into the 8-pin port located adjacent to the CPU socket?

Cevabı ve açıklamayı göster

Cevap: 8-pin EPS12V power connector

Cevap

The 8-pin EPS12V power connector is the correct choice for supplying dedicated auxiliary power directly to the CPU socket on the motherboard.
The 8-pin EPS12V power connector (or 4+4 pin CPU power cable) delivers dedicated +12V power directly to the processor via motherboard voltage regulator modules located adjacent to the CPU socket.

Adım Adım Çözüm

1
Identify the power requirements for the central processing unit (CPU).
Modern CPUs consume significant electrical current beyond what the 24-pin ATX motherboard main connector can deliver.
Dedicated +12V power lines are required near the processor socket to feed the CPU Voltage Regulator Module (VRM).
2
Evaluate the matching motherboard header and cable standard.
The 8-pin port located near the CPU socket matches the EPS12V standard (often split as a 4+4 pin connector on modular PSUs).
Connecting an EPS12V cable ensures correct voltage delivery and prevents system instability or POST failure.

A software development studio hosts its proprietary game engine source code on on-premises hardware that is dedicated exclusively to its own organization and managed internally by IT staff. To accommodate massive, unpredictable compute loads during short-term public beta playtests, the studio dynamically provisions additional virtual servers hosted by a commercial provider over the internet. Which TWO cloud deployment models are directly utilized in this organization's combined infrastructure? (Select TWO.)

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Private cloud; Public cloud

Cevap

The studio utilizes a Private cloud model for its internal, dedicated source code infrastructure and a Public cloud model for its on-demand, internet-accessible public beta servers.
The architecture combines an internal, single-tenant environment dedicated exclusively to the organization (Private cloud) with a third-party, multi-tenant environment accessible over the public internet for on-demand scaling (Public cloud).

Adım Adım Çözüm

1
Analyze the internal source code hosting requirements.
The infrastructure is located on-premises, dedicated strictly to a single organization, and controlled internally, matching the Private cloud deployment model.
Private clouds ensure isolated access and dedicated governance over highly sensitive proprietary data.
2
Analyze the public playtest server hosting requirements.
The compute capacity is provisioned from a commercial third-party provider over the public internet for global scale, matching the Public cloud deployment model.
Public clouds offer high elasticity and multi-tenant commercial availability for temporary workload scaling.
3
Evaluate and eliminate incorrect distractors.
Community cloud requires shared infrastructure across separate organizations. Infrastructure as a Service (IaaS) is a cloud service model category rather than a deployment model.
Differentiating between deployment models (who owns and accesses the environment) and service models (what computing layer is provided) is essential.

A network administrator is troubleshooting an issue on an enterprise Windows 11 workstation. The user reports that entering legitimate internal domain names into any installed web browser (Microsoft Edge, Google Chrome, or Mozilla Firefox) immediately routes them to an unfamiliar external site requesting account credentials. An initial inspection confirms there are no rogue browser extensions installed, system proxy settings are configured to automatically detect settings, and flushing the local DNS cache did not resolve the issue. Which of the following is the NEXT best troubleshooting step to identify the cause of the redirection?

Cevabı ve açıklamayı göster

Cevap: Inspect the Windows hosts file for malicious static IP mapping entries.

Cevap

Inspect the local Windows hosts file for malicious static IP mapping entries.
Inspecting the local Windows hosts file is the best NEXT step because the OS checks this local text file for domain-to-IP mappings prior to sending external DNS requests. Malicious software often inserts lines mapping legitimate website names to malicious IP addresses, causing consistent redirections across all web browsers installed on the machine.

Adım Adım Çözüm

1
Analyze symptoms across multiple web browsers
The issue affects all installed browsers (Edge, Chrome, Firefox) equally, indicating a system-level configuration or network resolution override rather than an isolated browser extension or profile issue.
Rogue extensions typically affect only the specific browser in which they are installed.
2
Evaluate local system resolution files
Check the C:\Windows\System32\drivers\etc\hosts file to see if malicious entries map legitimate corporate domain names to external rogue IP addresses.
The Windows operating system evaluates the local hosts file before sending DNS queries to configured name servers.
3
Differentiate hosts file redirection from proxy or pop-up issues
Because proxy settings are already verified clean and DNS flushing failed, static IP mappings in the hosts file remain the primary vector causing cross-browser domain hijacking.
Modifying the hosts file allows malware to redirect specific domain queries without triggering browser proxy alerts.

A system administrator is upgrading a desktop workstation by installing a dedicated PCI Express graphics card rated at 250 W250\text{ W} TDP. The existing system components (CPU, motherboard, RAM, and storage) draw a combined total of 165 W165\text{ W} under peak load. To maintain hardware longevity and efficiency, the workstation's total continuous power draw must not exceed 80%80\% of the power supply unit's (PSU) total rated capacity. Which of the following represents the minimum standard PSU wattage rating required for this upgraded system?

Cevabı ve açıklamayı göster

Cevap: 550 W550\text{ W}

Cevap

A 550 W550\text{ W} power supply unit is the minimum standard rating required.
Total continuous power draw is calculated by adding the GPU power (250 W250\text{ W}) to the rest of the workstation components (165 W165\text{ W}), resulting in 415 W415\text{ W}. To meet the requirement that 415 W415\text{ W} does not exceed 80%80\% of total rating, calculate 4150.80=518.75 W\frac{415}{0.80} = 518.75\text{ W}. The smallest standard PSU rating that meets or exceeds 518.75 W518.75\text{ W} is 550 W550\text{ W}.

Adım Adım Çözüm

1
Calculate total peak component power draw
250 W+165 W=415 W250\text{ W} + 165\text{ W} = 415\text{ W} continuous load
Summing GPU power consumption with the combined draw of all other system hardware gives total system demand.
2
Apply the 80% maximum workload constraint to find minimum required PSU wattage
415 W0.80=518.75 W\frac{415\text{ W}}{0.80} = 518.75\text{ W}
To ensure peak system load does not exceed 80% of PSU capacity, total draw is divided by 0.80.
3
Select the next highest standard PSU capacity rating
A 550 W550\text{ W} power supply unit
Because power supplies are sold in discrete capacity increments, the minimum standard rating exceeding 518.75 W518.75\text{ W} is 550 W550\text{ W}.

Cevap: DVI-I connectors integrate both analog and digital video signals, allowing a passive DVI-to-VGA adapter to function.; DVI-D connectors support digital signals only, preventing passive pin adapters from delivering an analog VGA signal.

Cevap

DVI-I connectors integrate both analog and digital video signals, allowing a passive DVI-to-VGA adapter to function, and DVI-D connectors support digital signals only, preventing passive pin adapters from delivering an analog VGA signal.
DVI-I (Integrated) includes dedicated pin channels for both digital data and analog RGB signals, which enables passive pass-through adapters to route the analog pins directly to a VGA connector. Conversely, DVI-D (Digital) lacks the physical analog pins around the ground blade, meaning it cannot output an analog signal without an active digital-to-analog converter box.

Adım Adım Çözüm

1
Identify the signal characteristics of DVI-I connectors.
DVI-I (Integrated) features four additional pins around the flat blade that carry analog RGB signals alongside the digital pins.
Because analog signals are natively present on DVI-I, a low-cost passive pin adapter can route those pins directly to a VGA (DB-15) connector.
2
Identify the signal characteristics of DVI-D connectors.
DVI-D (Digital-only) connectors omit the analog pins around the flat blade.
Without physical analog signal pins, DVI-D ports cannot output an analog signal to a VGA monitor via a simple passive adapter; an active signal converter is required.
3
Evaluate the statements regarding DVI-A and USB-C adapter claims.
DVI-A supports analog video only (no digital signal), while DVI-D lacks analog hardware capabilities regardless of external USB-C adapters.

Cevap: The Mini-ITX motherboard mounting holes align directly with four standard ATX chassis standoff locations.; The motherboard can be powered directly using a standard 24-pin ATX main power supply connector.

Cevap

The correct statements are that Mini-ITX motherboard mounting holes align directly with four standard ATX chassis standoff locations, and the motherboard can be powered directly using a standard 24-pin ATX main power supply connector.
Mini-ITX motherboards are engineered to be backward compatible with standard ATX computer cases. They share the same rear I/O shield dimensions and align with four of the standard ATX mounting standoffs. Additionally, Mini-ITX motherboards utilize standard 24-pin ATX power supply connectors.

Adım Adım Çözüm

1
Evaluate chassis mounting compatibility for Mini-ITX in an ATX enclosure.
Identify that Mini-ITX (170 mm×170 mm170 \text{ mm} \times 170 \text{ mm}) shares four standardized standoff hole placements with the full ATX form factor specification.
Backward compatibility ensures smaller form factor boards can be mounted in larger compatible cases without custom brackets.
2
Evaluate power connector specification requirements.
Confirm that standard Mini-ITX system boards use standard 24-pin ATX main power connectors.
Standard desktop ATX power supply units (PSUs) supply standard voltages (+3.3V, +5V, +12V) through standard 24-pin P1 connectors across ATX, Micro-ATX, and Mini-ITX motherboards.
