A technician is configuring a kiosk that uses a tablet to display digital signage. The tablet must be powered continuously and connected to a wired network for reliability. The tablet has a single USB-C port. How should the technician provide both power and network connectivity?
⚠ Common exam trap
A common pitfall is assuming a single USB-C port can only handle one function at a time, but USB-C with alternate modes and Power Delivery allows simultaneous data, video, and power over the same port.
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
✓
Connect a USB-C hub that provides both Ethernet and Power Delivery charging.
A USB-C hub with Power Delivery (PD) and Ethernet allows the tablet to receive both power and wired network connectivity through a single USB-C port. USB-C PD supports up to 100W (20V/5A) for charging, while the hub's Ethernet controller provides a stable wired network connection, meeting the requirements for continuous power and reliability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a USB-C to Ethernet adapter and charge the tablet wirelessly.
Why it's wrong here
While a USB-C to Ethernet adapter provides the wired network connection, relying on wireless charging for a kiosk is problematic. Wireless charging is significantly less efficient than wired charging, generating more heat and potentially failing to provide continuous power for 24/7 operation. Furthermore, not all tablets support wireless charging, making this an unreliable and potentially incompatible solution for a dedicated kiosk that requires constant uptime.
- ✓
Connect a USB-C hub that provides both Ethernet and Power Delivery charging.
Why this is correct
This is the most appropriate solution because a USB-C hub with Power Delivery (PD) pass-through allows the tablet to receive continuous power while simultaneously utilizing a wired Ethernet connection. USB-C's multi-functionality enables a single port to handle both high-speed data (for Ethernet) and power (via PD), making it ideal for kiosks requiring both reliable network access and constant charging without occupying multiple ports or requiring separate adapters.
- ✗
Use a Wi-Fi connection and a standard USB-C charger.
Why it's wrong here
Although a standard USB-C charger provides necessary power, relying solely on a Wi-Fi connection for a kiosk introduces significant reliability issues. Wireless networks are prone to interference, signal drops, and security vulnerabilities, which are unacceptable for a critical application like a kiosk that demands consistent uptime and stable data transfer. The scenario implicitly requires the superior stability and security of a wired network connection.
- ✗
Connect the tablet to the network via Bluetooth tethering to a phone.
Why it's wrong here
Bluetooth tethering is an entirely unsuitable option for a kiosk due to its inherent limitations in speed and reliability. Bluetooth offers significantly lower bandwidth compared to wired Ethernet or even Wi-Fi, making it inefficient for continuous data transfer required by a kiosk. Moreover, this method does not provide any power to the tablet, which is crucial for a kiosk's extended operation, and it introduces an unnecessary dependency on another device (a phone).
