A system administrator is sizing a replacement power supply unit (PSU) for a CAD workstation. The internal components have the following continuous power specifications:

- CPU: $105\text{ W}$
- PCIe Graphics Card: $280\text{ W}$
- PCIe Sound & Capture Cards: $35\text{ W}$ total
- Motherboard, RAM, and Storage Drives: $40\text{ W}$ total

To account for brief GPU transient power excursions, a $35\%$ power overhead must be applied specifically to the graphics card TDP. Additionally, to ensure hardware longevity and system stability, the final total system peak draw must not exceed $80\%$ of the power supply's rated capacity (requiring a $20\%$ safety headroom margin).

What is the minimum recommended PSU wattage rating required for this workstation?

700\text{ W}

600\text{ W}

500\text{ W}

460\text{ W}

Cevabı ve açıklamayı göster

Cevap: $700\text{ W}$

Cevap

The minimum recommended PSU wattage rating is

700\text{ W}

The correct option (

700\text{ W}

) properly factors in the GPU's

35\%

transient power spike (

280\text{ W} \times 1.35 = 378\text{ W}

), resulting in a combined peak system draw of

558\text{ W}

. Accounting for the mandated

20\%

safety headroom margin (

558 / 0.80 = 697.5\text{ W}

) dictates selecting at least a

700\text{ W}

rated power supply unit.

Adım Adım Çözüm

Calculate the adjusted peak draw for the GPU including the 35% transient allowance.

\text{Adjusted GPU Power} = 280\text{ W} \times 1.35 = 378\text{ W}

Modern graphics cards exhibit short-duration power spikes above their rated TDP during intensive workloads.

Sum all system component power draws to determine the total peak power requirement.

\text{Total Peak Power} = 105\text{ W} \text{ (CPU)} + 378\text{ W} \text{ (GPU)} + 35\text{ W} \text{ (Expansion Cards)} + 40\text{ W} \text{ (System)} = 558\text{ W}

All components draw from the power supply simultaneously during peak operational load.

Apply the 20% safety headroom margin requirement (total load

\le 80\%

of PSU capacity).

\text{Minimum Required PSU Capacity} = \frac{558\text{ W}}{0.80} = 697.5\text{ W}

Operating a PSU below 80% capacity prevents thermal degradation, avoids unexpected shutdowns, and maximizes power conversion efficiency.

Select the next available standard commercial PSU wattage rating.

Select

700\text{ W}

PSU (or

750\text{ W}

700\text{ W}

is unavailable).

Power supplies are manufactured in discrete wattage tiers.

Cevap: SMB protocol settings and target folder network path; Network authentication credentials with write permissions to the shared folder

Cevap

Configuring SMB protocol settings with the target network path and providing valid authentication credentials with write permissions to the shared directory.

To successfully scan documents directly to a shared network folder, an MFD must be configured with SMB (Server Message Block) protocol details including the network path, alongside valid authentication credentials that have write permissions to access and save files into that folder.

Adım Adım Çözüm

Identify the target network service required for scanning to a network folder.

The requirement uses SMB (Server Message Block) protocol for file sharing over a network.

Scan-to-SMB relies on network file sharing protocols rather than email protocols.

Determine the necessary parameters for the MFD to write files to the share.

The MFD requires the destination network path (SMB settings) and user credentials with write privileges.

Without valid pathing and write permissions, the MFD cannot authenticate or deposit scanned files into the share.

Soru 404Soru →

A server administrator is provisioning storage for a compact edge computing system that features two dedicated M.2 slots on the motherboard:
- Slot A is wired exclusively to four PCIe 4.0 lanes ( $\times 4$ ) from the CPU and supports the NVMe protocol.
- Slot B is connected exclusively to the onboard SATA host controller.

The administrator has two M.2 solid-state drives: an M.2 NVMe SSD and an M.2 SATA SSD. Which TWO of the following statements correctly describe drive compatibility and performance characteristics for this hardware configuration? (Select TWO.)

Geçerli olan tümünü seçin

Installing the M.2 NVMe SSD into Slot B will result in the drive not being recognized by the system because Slot B lacks PCIe lane connectivity.

The M.2 SATA SSD installed in Slot B will be limited to a maximum theoretical transfer throughput of

6\text{ Gbps}

Installing the M.2 SATA SSD into Slot A will automatically convert its operating protocol to match NVMe PCIe 4.0 speeds.

Both M.2 SSD types utilize the same underlying host bus protocol regardless of whether they communicate over SATA or PCIe signaling.

Cevabı ve açıklamayı göster

Cevap: Installing the M.2 NVMe SSD into Slot B will result in the drive not being recognized by the system because Slot B lacks PCIe lane connectivity.; The M.2 SATA SSD installed in Slot B will be limited to a maximum theoretical transfer throughput of $6\text{ Gbps}$ .

Cevap

Installing the M.2 NVMe SSD into Slot B results in the drive not being recognized due to the lack of PCIe connectivity, and the M.2 SATA SSD performance is constrained to the SATA III transfer limit of

6\text{ Gbps}

The M.2 form factor is a physical connector standard that can carry either PCIe (NVMe) or SATA protocol signals depending on motherboard trace routing. Because Slot B connects exclusively to a SATA host controller without PCIe lanes, an NVMe SSD installed there cannot communicate and will not be detected. Conversely, an M.2 drive using the SATA protocol is bound by the hardware limitations of the SATA III standard, which caps bandwidth at

6\text{ Gbps}

Adım Adım Çözüm

Analyze the bus wiring and protocol support of Slot B.

Slot B only connects to the SATA host controller and lacks PCIe lanes.

NVMe drives require a PCIe interface to operate; without PCIe signaling, an NVMe SSD will fail to detect.

Evaluate the protocol ceiling of the M.2 SATA drive.

The SATA interface limits transfer speeds to

6\text{ Gbps}

SATA III bus architecture caps theoretical bandwidth at

6\text{ Gbps}

regardless of the physical M.2 slot form factor.

A network technician is deploying a corporate Multifunction Device (MFD) to support secure Scan-to-Email using authenticated SMTP over TLS with a cloud-based email provider. In what logical sequence should the technician perform the following steps to complete the configuration?

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct order of steps is: 1) Verify TCP/IP network settings and specify valid internal DNS server addresses on the MFD; 2) Import the email provider's Root CA certificate into the MFD's trusted certificate store; 3) Configure the remote SMTP server FQDN, set the submission port to 587, and enable STARTTLS encryption; 4) Enter the dedicated service account login credentials for SMTP user authentication; 5) Execute a test scan-to-email transaction from the MFD control panel to verify message delivery.

The configuration follows a standard system dependency hierarchy: basic IP and DNS name resolution must be established first, followed by cryptographically trusting the remote server (Root CA), setting up encrypted protocol endpoints (SMTP port 587 with STARTTLS), applying user authentication credentials, and finally performing functional validation.

Adım Adım Çözüm

Ensure IP addressing and DNS server configuration on the MFD.

The device achieves network layer reachability and can resolve external hostnames.

Without name resolution, the MFD cannot establish communication with domain-based cloud SMTP servers.

Install the public Root CA certificate on the MFD via EWS.

Soru 407Soru →

A system administrator is configuring a newly installed enterprise multifunction device (MFD). Users need to select employee email addresses directly from the corporate Active Directory directory at the device's touch screen interface when using the Scan-to-Email feature, rather than entering addresses manually. The administrator specified the domain controller's IP address on the MFD, but directory searches fail and time out. Network firewalls allow standard traffic between subnets. Which configuration setting on the MFD must the administrator configure to enable dynamic directory lookups?

Cevabı ve açıklamayı göster

Cevap: Enable LDAP settings and specify the bind user account credentials with the target search base DN.

Cevap

Enable LDAP settings and specify the bind user account credentials with the target search base DN.

To enable dynamic directory search on an MFD touch panel, Lightweight Directory Access Protocol (LDAP) must be configured. In addition to specifying the server address, the administrator must configure bind credentials (a domain service account) so the printer can authenticate to Active Directory, along with a search base (Distinguished Name) specifying where in the directory tree to search for users.

Adım Adım Çözüm

Identify the service requirement for address book auto-lookup on an MFD.

The MFD needs to dynamically query an Active Directory/domain directory for user email addresses.

Active Directory stores directory objects accessible via Lightweight Directory Access Protocol (LDAP).

Determine the necessary settings to establish an LDAP connection.

Providing an IP address alone is insufficient; the MFD requires authentication (bind credentials) and a starting point in the directory hierarchy (search base DN).

Active Directory restricts anonymous directory queries by default for security.

Evaluate alternative option roles.

DHCP options 66/67 relate to network boot, SNMP relates to status monitoring, and LLDP relates to link layer discovery.

None of these protocols provide directory search capabilities.

Cevabı ve açıklamayı göster

Cevap: The M-key NVMe drive will physically fail to fit into the B-key slot due to mechanical keying notch incompatibility.

Cevap

The M-key NVMe drive will physically fail to fit into the B-key slot due to mechanical keying notch incompatibility.

M.2 form factor specifications use mechanical keying notches to prevent users from installing incompatible devices. A B-key slot has pins 12–19 missing/notched and supports SATA or PCIe x2 interfaces, whereas an M-key SSD has pins 59–66 notched for PCIe x4 NVMe operation. Therefore, an M-key NVMe SSD physically cannot be inserted into a B-key slot.

Adım Adım Çözüm

Compare the mechanical keying of the target slot against the keying of the replacement drive.

The motherboard slot is B-keyed (notch at pins 12–19), while the replacement drive is M-keyed (notch at pins 59–66).

M.2 mechanical keying prevents inserting incompatible bus standards into designated motherboard slots.

Evaluate physical insertion compatibility.

Because the keying notches do not align, the drive cannot be physically inserted into the connector.

Keying prevents hardware damage caused by applying incorrect bus voltage or interface pins.

A technician is installing a Micro-ATX motherboard into a computer case that previously housed a standard ATX motherboard. After securing the motherboard with mounting screws and connecting all power and front-panel cables, the technician attempts to power on the system. The power supply fans momentarily spin for less than a second before immediately shutting down, and the motherboard status light indicates a power fault protection state. Which of the following is the most likely cause of this issue?

An unused brass standoff left in the chassis from the previous ATX motherboard configuration is shorting against the underside of the Micro-ATX board.

The technician connected a key-keyed 8-pin PCIe power cable into the motherboard's 8-pin EPS12V CPU power connector.

The motherboard requires an M.2 SATA SSD to be populated in slot M.2_1 to complete the main system power circuit prior to POST initialization.

The standard 24-pin ATX main power cable delivers inadequate wattage because it lacks the secondary 4-pin auxiliary power extension required for Micro-ATX form factors.

Cevap: An unused brass standoff left in the chassis from the previous ATX motherboard configuration is shorting against the underside of the Micro-ATX board.

Cevap

An unused brass standoff left in the chassis from the previous ATX motherboard configuration is shorting against the underside of the Micro-ATX board.

Standard ATX motherboards (12 x 9.6 inches) utilize additional standoff locations on the computer case chassis that extend beyond the lower perimeter of a Micro-ATX motherboard (9.6 x 9.6 inches). If a technician fails to remove the leftover standoff from the ATX layout, the metal standoff presses against electrical traces or component solder pins on the underside of the Micro-ATX motherboard. When power is applied, this creates an immediate short circuit to the grounded case chassis, triggering the power supply's short-circuit protection (SCP) mechanism and causing an immediate power-off state.

Adım Adım Çözüm

Analyze the physical dimension and mounting footprint differences between form factors.

Standard ATX motherboards measure 12 x 9.6 inches and use up to 9 or 10 mounting standoffs, whereas Micro-ATX boards measure 9.6 x 9.6 inches and use up to 8 standoffs in slightly different layout grids.

When replacing a larger motherboard form factor with a smaller one, standoff locations that do not align with the new motherboard's reinforced screw holes must be removed from the case tray.

Evaluate the reported symptom of immediate shutdown after power-on.

Fans spinning for under a second followed by system shutdown indicates short-circuit protection (SCP) or over-current protection (OCP) within the power supply unit.

Direct contact between a metal standoff and electrical traces on the back of the motherboard creates a zero-resistance path to ground, forcing the power supply to trip safety shutoffs.

A technician installs a secondary PCIe x4 expansion card into a desktop motherboard's second expansion slot. Immediately after booting the system, diagnostic software indicates that the primary PCIe x16 slot hosting the dedicated graphics card has dropped its operating link width from x16 down to x8 mode. Which of the following motherboard features or design characteristics is responsible for this behavior?

PCIe lane multiplexing between expansion slots sharing CPU-attached lanes

M.2 SATA keying fallback forcing interface protocol renegotiation

Single-channel RAM population triggering systemic bus throttling

Insufficient EPS12V power supply delivery to the motherboard PCIe bus

Cevap: PCIe lane multiplexing between expansion slots sharing CPU-attached lanes

Cevap

PCIe lane multiplexing between expansion slots sharing CPU-attached lanes

Motherboards designed to support multiple high-bandwidth expansion slots often multiplex PCIe lanes connected directly to the CPU. When a secondary card is inserted into a shared slot, the motherboard automatically redistributes the available lanes, reducing the primary slot's width from x16 to x8 to supply x8 or x4 lanes to the newly occupied slot.

Adım Adım Çözüm

Analyze the observed hardware behavior

Populating a secondary PCIe slot causes the primary PCIe slot's link width to change from x16 to x8.

This is a characteristic symptom of motherboard PCIe lane reallocation or bifurcation.

Evaluate motherboard lane distribution design

Processor root complexes have a limited count of PCIe lanes (typically 16-24 direct CPU lanes). Motherboard manufacturers multiplex these lanes across multiple physical PCIe slots.

When the second slot is used, the motherboard splits the 16 primary lanes into two x8 channels so both slots remain active.

A desktop computer equipped with basic hardware requires a power supply upgrade after installing additional expansion components. The total peak power consumption of all internal components is calculated at $300\text{ W}$ . To maintain a recommended $20\%$ power headroom margin for system stability, which minimum wattage power supply unit (PSU) should be installed?

360\text{ W}

300\text{ W}

240\text{ W}

150\text{ W}

Cevabı ve açıklamayı göster

Cevap: $360\text{ W}$

Cevap

The minimum wattage power supply unit that should be installed is

360\text{ W}

The total system power requirement with a

20\%

headroom margin is calculated as

300\text{ W} \times 1.20 = 360\text{ W}

. This ensures stable operation under maximum load while protecting the system against transient power surges.

Adım Adım Çözüm

Identify total peak power draw of internal components

Total peak draw is

300\text{ W}

This establishes the baseline power required by the computer components.

Calculate the necessary overhead margin multiplier

20\%

headroom multiplier is

1 + 0.20 = 1.20

Adding a safety margin prevents power supply overload during power spikes and ensures long-term power supply efficiency.

Multiply total draw by headroom multiplier

300\text{ W} \times 1.20 = 360\text{ W}

This yields the total minimum wattage capacity needed for the replacement PSU.
