The answer is 802.11ax, commonly known as Wi-Fi 6, because it is the fastest wireless standard currently available for home networks, delivering theoretical speeds up to 9.6 Gbps and significantly outperforming older standards like Wi-Fi 5 (802.11ac) in real-world conditions. This standard achieves its superior throughput through advanced technologies such as OFDMA, which divides channels into smaller sub-channels to reduce latency, and MU-MIMO, which allows the router to communicate with multiple devices simultaneously rather than one at a time—both critical for lag-free 4K streaming and competitive gaming when many devices are connected. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your ability to match a wireless standard to bandwidth-intensive use cases, often with a trap answer of 802.11ac (Wi-Fi 5), which supports up to 3.5 Gbps but lacks the dense-environment efficiency of Wi-Fi 6. Remember that even though the customer’s cable modem caps at 1 Gbps, Wi-Fi 6 still provides better multi-device handling and lower latency, making it the future-proof choice. A helpful memory tip: “Six is the fix for streaming and gaming mix.”
220-1101 Wireless Networking Technologies Practice Question
This 220-1201 practice question tests your understanding of wireless networking technologies. 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 customer wants to set up a home network that supports the fastest possible speeds for streaming 4K video and gaming, with support for multiple devices. They have a cable modem that supports up to 1 Gbps. Which wireless standard should you recommend for the new router?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
802.11ax (Wi-Fi 6)
Wi-Fi 6 (802.11ax) offers the highest throughput, better efficiency in dense environments, and supports the latest features like OFDMA and MU-MIMO. It is the best choice for high-bandwidth activities like 4K streaming and gaming.
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.
✗
802.11ac (Wi-Fi 5)
Why it's wrong here
While fast, 802.11ac is older and does not match the efficiency and speed of Wi-Fi 6, especially under multiple devices.
✗
802.11n (Wi-Fi 4)
Why it's wrong here
802.11n is outdated and maxes out at lower speeds, insufficient for multiple 4K streams.
✓
802.11ax (Wi-Fi 6)
Why this is correct
Wi-Fi 6 provides the highest real-world speeds, better handling of multiple devices, and is backward compatible.

Read the scenario before looking for a memorised answer.
✗
802.11g (Wi-Fi 3)
Why it's wrong here
802.11g is very old, with speeds below 54 Mbps, and cannot support 4K streaming or gaming.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
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.

Variation 1. A technician is setting up a wireless network for a home office that requires the fastest possible speeds for streaming 4K video. The router supports 802.11ac and has three antennas. Which configuration will yield the highest throughput?
easy
A.Set the router to 802.11n mode only.
B.Enable 40 MHz channel width on the 2.4 GHz band.
✓ C.Use the 5 GHz band with MIMO enabled and a channel width of 80 MHz.
D.Disable SSID broadcast to reduce overhead.
Why C: 802.11ac uses MIMO (Multiple Input Multiple Output) technology, which requires multiple spatial streams to achieve high throughput. Enabling MIMO with all antennas maximizes data rates, especially for streaming.
