Difficulty: MediumLaptop Hardware Components and Upgrades

A field technician is configuring an enterprise laptop to connect to a high-performance docking station requiring dual 4K video outputs and external PCIe bandwidth over a single connection. The laptop has multiple physical USB Type-C ports, but only one designated port operates all connected dock peripherals and displays correctly. Which host controller protocol capability must the technician verify on the laptop port to ensure full functionality with this dock?

  1. Thunderbolt protocol support integrated into the specific USB Type-C port controllerAnswer
  2. B
    Standard USB 3.2 Gen 1 data transfer support across all motherboard Type-C physical interfaces
  3. C
    Installation of a 288-pin desktop DIMM module into the internal expansion slot to allocate video memory
  4. D
    Execution of a complete zero-percent deep discharge cycle on the internal Lithium-ion battery prior to docking

Answer

The technician must verify Thunderbolt protocol support on the specific USB Type-C port host controller.
Thunderbolt technology (such as Thunderbolt 3 or 4) uses the USB Type-C connector shape but adds dedicated high-bandwidth capabilities, including PCIe data tunneling and dual DisplayPort video channels. Verifying Thunderbolt host controller support on the specific laptop port ensures the single cable can drive dual 4K monitors and high-speed dock peripherals simultaneously.

Step-by-Step Solution

1
Identify the physical interface and requirement
The docking station requires high-bandwidth video and PCIe throughput over a physical USB Type-C form factor.
Physical USB Type-C connectors support multiple underlying protocols which vary by port.
2
Differentiate connector shape from protocol capabilities
Confirm that only ports backed by a Thunderbolt host controller support dual 4K video streams and PCIe tunneling.
Standard USB 3.2 protocols lack sufficient bandwidth and alternate mode capabilities for dual 4K docking.
3
Select the correct port and verification standard
Connect the dock specifically to the Thunderbolt-enabled USB Type-C port.
Ensures full compatibility and feature utilization of the external workstation dock.
