The correct choice is a USB-C to HDMI adapter or cable. This is because when a laptop’s USB-C port supports DisplayPort Alt Mode, it can transmit a native video signal that a simple passive adapter can convert directly to HDMI, allowing the projector to display 4K content without needing any active conversion or additional drivers. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of USB-C Alternate Modes and the importance of matching cable types to port capabilities—a common trap is assuming any USB-C cable works for video, when in fact the port must explicitly support Alt Mode and the adapter must be designed for that signal path. A helpful memory tip: think “Alt Mode = Alternate Path for Video,” so if the USB-C port supports it, a straight USB-C to HDMI adapter is the direct route to the display.
220-1101 Connectors Practice Question
This 220-1201 practice question tests your understanding of connectors. 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 user wants to connect a laptop to a 4K projector for a presentation. The laptop has a USB-C port that supports DisplayPort Alt Mode, and the projector has an HDMI input. Which cable or adapter is required?
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 HDMI adapter or cable
The correct answer is C because USB-C to HDMI cables or adapters are designed for this exact scenario when the USB-C port supports DisplayPort Alt Mode. This tests understanding of USB-C Alt Mode and the need for compatible cables.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 USB-C cable
Why it's wrong here
The projector has HDMI input, not USB-C, so a USB-C to USB-C cable would not connect to the projector.
✗
HDMI to HDMI cable
Why it's wrong here
The laptop has USB-C, not HDMI, so an HDMI cable cannot connect directly.
✓
USB-C to HDMI adapter or cable
Why this is correct
This cable converts the USB-C signal to HDMI, leveraging DisplayPort Alt Mode for video output.
Related concept
Static NAT maps one inside address to one outside address.
✗
DisplayPort to HDMI cable
Why it's wrong here
The laptop has USB-C, not DisplayPort, so this cable would not connect to the laptop.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
