FC0-U71 Infrastructure Practice Question
A user wants to connect a new external monitor to a laptop that has only USB-C ports. The monitor supports HDMI and DisplayPort inputs. The user needs to drive the monitor at its native resolution and also charge the laptop through the same connection. Which of the following should the technician recommend?
⚠ Common exam trap
The trap here is assuming any USB-C video adapter also provides charging, when only those with USB Power Delivery support can do both.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A USB-C docking station that supports DisplayPort Alt Mode and USB Power Delivery.
A USB-C docking station supporting DisplayPort Alt Mode and USB Power Delivery allows video output and laptop charging over a single USB-C cable. This satisfies both the monitor connection and charging requirements. It also provides a clean, single-cable solution that many modern laptops are designed to support.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A USB-C to HDMI adapter that supports video output.
Why it's wrong here
A USB-C to HDMI adapter can carry video, but many basic adapters do not support power delivery to charge the laptop. The user specifically needs charging through the same connection. Without USB Power Delivery support, the laptop would still require a separate charger, failing the requirement.
- ✗
A USB-A to HDMI cable connected through a USB hub.
Why it's wrong here
USB-A ports do not natively carry DisplayPort or HDMI video signals. A USB-A to HDMI cable typically requires DisplayLink drivers and may not support native resolution or charging. This option fails to provide both video and power delivery through a single connection as required.
- ✓
A USB-C docking station that supports DisplayPort Alt Mode and USB Power Delivery.
Why this is correct
A USB-C dock with DisplayPort Alt Mode and USB Power Delivery can output video to the monitor and charge the laptop simultaneously over a single cable. This meets both the display and charging requirements. It also typically provides additional ports, making it a versatile solution for laptop connectivity.
- ✗
A Thunderbolt 2 to HDMI adapter with a separate power brick.
Why it's wrong here
Thunderbolt 2 uses a different connector than USB-C and is not compatible without an additional adapter. This adds complexity and may not support charging over the same cable. The laptop has USB-C ports, so a native USB-C solution is more appropriate and reliable.
