Zorluk: OrtaNetwork and Peripheral Cables and Connectors

A field technician is deploying a workstation dock connected to a laptop's host port labeled with a Thunderbolt 4 icon. Which of the following capabilities and underlying protocols are natively supported by the Thunderbolt 4 specification over its USB Type-C physical connector? (Select TWO.)

  1. PCI Express (PCIe) data tunneling for external storage drive arrays and expansion chassisCevap
  2. DisplayPort Alternate Mode for driving external high-resolution digital video monitors directlyCevap
  3. C
    Native RS-232 serial bus signaling without using an active serial protocol converter
  4. D
    Direct analog VGA RGB video transmission over passive physical adapter wiring

Cevap

Thunderbolt 4 natively supports PCI Express (PCIe) bus tunneling for high-speed peripherals and DisplayPort Alternate Mode for direct digital video output over a physical USB Type-C connector.
Thunderbolt 4 built upon the USB Type-C connector specification natively encapsulates PCIe data packets (allowing direct host bus performance for external drives and docking stations) and supports DisplayPort Alternate Mode (delivering uncompressed digital video to external monitors). Both features function without needing active protocol translation chipsets.

Adım Adım Çözüm

1
Identify the physical connector and underlying interface protocol standard specified in the scenario.
The scenario specifies a Thunderbolt 4 controller operating through a USB Type-C physical port.
Thunderbolt 4 standardizes specific native data and video protocols that can be multiplexed over the USB Type-C cable assembly.
2
Evaluate the supported native protocols against the provided options.
Thunderbolt 4 mandates PCIe data tunneling (up to 32 Gbps PCIe data throughput) and native DisplayPort Alternate Mode for dual 4K or single 8K displays.
These capabilities allow high-speed external peripheral access and multi-monitor display outputs without external protocol conversion cards.
3
Filter out invalid legacy or analog signaling assumptions.
RS-232 serial and analog VGA are not supported natively and require active translation adapters.
USB-C and Thunderbolt interfaces handle modern digital packets, lacking legacy analog video DAC pinouts or direct serial UART lines.
