The answer is a USB-C to Ethernet adapter. This device converts the tablet’s USB-C port into a standard RJ45 Ethernet jack, allowing a direct wired network connection where Wi-Fi is not permitted. The adapter internally handles the signal translation from the USB protocol to the Ethernet standard, so the operating system sees it as a standard network interface. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your ability to match the correct adapter type to a given port and network requirement—a common trap is confusing this with a USB-C to HDMI or a simple USB-C hub that lacks an Ethernet port. Remember that any device needing a wired connection but lacking an RJ45 port will require a dedicated Ethernet adapter for that specific port type. A useful memory tip: “USB-C to RJ45—no Wi-Fi, no fuss, just plug and connect.”
220-1201 Mobile Device Connection Methods Practice Question
This 220-1201 practice question tests your understanding of mobile device connection methods. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is configuring a kiosk tablet that must connect to a wired Ethernet network for security reasons. The tablet only has a USB-C port. The network drop provides an RJ45 connection. Which of the following should the technician use to achieve a wired connection?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
USB-C to Ethernet adapter
USB-C to Ethernet adapters are standard and allow wired network connections on devices without Ethernet ports. This tests knowledge of adapter types and the ability to select the correct one for a given port and network interface.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
USB-C to HDMI adapter
Why it's wrong here
HDMI is for video, not network data; it cannot provide an Ethernet connection.
✗
USB-C to USB-A adapter with a USB Ethernet dongle
Why it's wrong here
While this could work, it introduces unnecessary complexity; a direct USB-C to Ethernet adapter is simpler and more reliable.
✓
USB-C to Ethernet adapter
Why this is correct
This adapter directly converts the USB-C port to an RJ45 Ethernet port, providing a wired network connection.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
