An IT technician is connecting a workstation with a newly installed dedicated graphics card to an older projector that only accepts a VGA (DB-15) input. The workstation's graphics card provides only a DVI-D output port. The technician connects the display using a passive DVI-to-VGA adapter, but the projector displays a 'No Signal' message upon powering on. Which of the following best explains why this connection failed?

Cevabı ve açıklamayı göster

Cevap: DVI-D ports output digital signals only and lack the analog pinouts required for a passive VGA adapter to function.

Cevap

DVI-D ports output digital signals only and lack the analog pinouts required for a passive VGA adapter to function.
DVI-D stands for DVI-Digital. It carries only digital signals. A passive adapter does not contain electronic circuitry to convert digital signals to analog signals; it merely redirects pins. Because VGA is strictly analog and DVI-D lacks the four analog pins present in DVI-I or DVI-A, a passive adapter cannot pass video to a VGA display. An active digital-to-analog converter is required.

Adım Adım Çözüm

1
Identify the video output standard on the graphics card and the input standard on the projector.
The graphics card outputs DVI-D (Digital only), while the projector accepts VGA (Analog DB-15).
Determining signal compatibility is the first step in troubleshooting display connectivity.
2
Evaluate the capabilities of a passive adapter between DVI-D and VGA.
A passive adapter only pin-maps signals without performing active signal conversion; DVI-D lacks analog pins (C1-C4 pins found around the flat blade in DVI-I/DVI-A).
Without analog pins present in the source port, no analog signal reaches the VGA connector.
3
Determine the required solution to establish a working display connection.
An active DVI-D to VGA converter powered by an integrated chipset is necessary to translate digital signals to analog.
Active conversion translates digital packets to analog voltage waveforms required by VGA.

Cevap: Local storage hard drive encryption; Secure Print (PIN/badge user authentication)

Cevap

Enabling local storage hard drive encryption and configuring Secure Print (PIN/badge authentication) fulfills the data confidentiality and unattended document retrieval security mandates.
To satisfy security requirements for data at rest and physical document collection, hard drive encryption protects cached documents stored on the MFD's internal drive, while Secure Print ensures documents are only printed when the user physically authenticates at the device control panel.

Adım Adım Çözüm

1
Identify the threat of unauthorized physical disk access and data remanence on the MFD.
Local storage hard drive encryption protects stored job data and swap files on the MFD's internal drive from physical theft or extraction.
MFDs utilize internal storage drives to buffer large print jobs and store scanned documents, making drive encryption essential for confidential data compliance.
2
Identify the threat of sensitive hard-copy documents being left unattended in the paper tray.
Secure Print forces job release only after user authentication at the physical device.
Requiring a PIN, password, or badge tap at the MFD console ensures that the user is physically present to collect sensitive prints as soon as they are generated.
