Difficulty: MediumNetwork and Peripheral Cables and Connectors

A field technician is setting up a high-performance workstation that requires connecting an external storage enclosure needing up to 40 Gbps data bandwidth alongside an external 4K monitor over a single cable interface. Which TWO of the following statements correctly describe the cable and protocol capabilities required for this setup?

  1. Thunderbolt 4 cables use the physical USB Type-C connector standard and support up to 40 Gbps data throughput.Answer
  2. DisplayPort Alternate Mode allows compatible USB Type-C ports to transmit native video signals directly to external displays.Answer
  3. C
    Any standard USB 3.2 Gen 2 Type-C cable will automatically support PCIe tunneling and 40 Gbps transfer speeds.
  4. D
    Thunderbolt 4 host ports use a proprietary pin layout that prevents backwards compatibility with standard USB 2.0 or 3.0 peripherals.

Answer

The correct statements are that Thunderbolt 4 cables use the physical USB Type-C connector standard while supporting up to 40 Gbps data throughput, and that DisplayPort Alternate Mode allows compatible USB Type-C ports to transmit native video signals directly to external displays.
Thunderbolt 4 utilizes the physical USB Type-C form factor while guaranteeing a maximum throughput of 40 Gbps, full PCIe data tunneling, and backward compatibility. Furthermore, USB Type-C interface specifications include DisplayPort Alternate Mode, allowing compatible host ports and cables to output native video to external high-resolution monitors.

Step-by-Step Solution

1
Identify the bandwidth and signaling requirements stated in the scenario.
The requirement specifies 40 Gbps data transfer for storage, external display connectivity, and a single cable interface.
Matching physical connectors to underlying protocol capabilities is critical in modern peripheral deployments.
2
Evaluate the capabilities of Thunderbolt 4 and USB Type-C physical connectors.
Thunderbolt 4 uses the USB Type-C physical connector, guarantees 40 Gbps bandwidth, and supports PCIe and DisplayPort data tunneling.
Thunderbolt 4 enforces strict bandwidth certification over the USB Type-C form factor.
3
Evaluate video transport features over USB Type-C.
DisplayPort Alt Mode permits native video transmission over physical USB-C pins.
Alt Mode features allow multi-function cables to handle video and high-speed data simultaneously.
