- A
Connect both monitors directly to the laptop using two separate USB-C to HDMI cables.
Why wrong: The scenario specifies daisy-chaining, not direct connections; also HDMI is not used here.
- B
Use a USB-C to DisplayPort cable from the laptop to the first monitor, then a DisplayPort cable from the first monitor to the second.
This daisy-chain configuration works if both monitors support DisplayPort MST, allowing video to pass through the first monitor to the second.
- C
Use a USB-C hub with two HDMI ports.
Why wrong: A hub would allow two separate connections, but the scenario requires daisy-chaining, not a hub.
- D
Use a single USB-C to DisplayPort cable that splits into two DisplayPort connectors.
Why wrong: Such splitters exist but are not standard for daisy-chaining; they may not support MST or 4K resolution on both monitors.
Quick Answer
The correct cable configuration is a USB-C to DisplayPort cable from the laptop to the first monitor, then a standard DisplayPort cable from the first monitor to the second. This works because Thunderbolt 3 supports daisy-chaining through DisplayPort over USB-C, relying on Multi-Stream Transport (MST) to split the single video signal across both 4K displays. Each monitor must have a DisplayPort input and support MST for the chain to function. On the CompTIA A+ Core 1 220-1201 exam, this tests your understanding of Thunderbolt 3’s video capabilities and the distinction between passive adapters and active MST hubs—a common trap is assuming you need a Thunderbolt 3 dock or a splitter. Remember the memory tip: “USB-C to DP first, then DP to DP—MST makes the chain work.”
220-1201 Mobile Device Connection Methods Practice Question
This 220-1201 practice question tests your understanding of mobile device connection methods. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 user's laptop has a USB-C port that supports Thunderbolt 3. They want to connect two 4K monitors daisy-chained. The monitors have DisplayPort inputs. Which cable configuration is required?
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
Use a USB-C to DisplayPort cable from the laptop to the first monitor, then a DisplayPort cable from the first monitor to the second.
Thunderbolt 3 supports daisy-chaining via DisplayPort over USB-C. Each monitor must have a DisplayPort input and support MST (Multi-Stream Transport). The first monitor connects to the laptop via USB-C to DisplayPort cable, and the second connects to the first monitor's DisplayPort out.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
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.
