Correct answers: A, B, C
Explanation
To address issues with a Thunderbolt 4 docking station, it is crucial to verify hardware compatibility, ensure the correct cable is used, and check for external power requirements. Thunderbolt technology relies on specific hardware and certified cables, and it cannot function properly without these requirements being met.
- A. Correct.
Not all USB-C ports support Thunderbolt 3 or Thunderbolt 4. Confirming compatibility is essential since Thunderbolt devices require specific hardware support.
- B. Correct.
Thunderbolt 4 requires a certified, high-speed USB-C cable for proper functioning. Using a non-Thunderbolt-certified cable may cause connection issues.
- C. Correct.
Many Thunderbolt 4 docking stations require an external power adapter to function. If the adapter is not connected, the device may not power on or detect peripherals.
- D. Incorrect.
While updating drivers can be helpful in some scenarios, Thunderbolt functionality is based on hardware support and requires no special USB driver installs.
- E. Incorrect.
A USB 2.0 hub is not compatible with Thunderbolt 4 docking stations, and replacing the docking station with such a hub would not resolve the issue.
