FC0-U71 Infrastructure Practice Question
A company wants to deploy a new wireless standard that offers higher throughput and better performance in dense environments. Which Wi-Fi standard should they choose?
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
✓
802.11ax (Wi-Fi 6)
802.11ax (Wi-Fi 6) is the latest standard, offering higher speeds, better efficiency, and improved performance in dense environments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
802.11n (Wi-Fi 4)
Why it's wrong here
802.11n operates only on 2.4 and 5 GHz with limited spatial streams, so it cannot deliver the throughput or dense-environment performance required. It is tempting because Wi-Fi 4 was a major leap over 802.11g, which is correct when upgrading legacy clients that lack Wi-Fi 5 or 6 radios.
- ✓
802.11ax (Wi-Fi 6)
Why this is correct
802.11ax (Wi-Fi 6) introduces OFDMA and MU-MIMO, letting one access point serve multiple clients simultaneously rather than contending for airtime. This directly satisfies the dense-environment constraint, where earlier standards such as 802.11ac degrade under high client counts. It also delivers higher throughput than 802.11ac.
- ✗
Bluetooth 5.0
Why it's wrong here
Bluetooth 5.0 is a short-range personal area networking specification, not a Wi-Fi standard, and provides no WLAN throughput or dense-deployment capacity. It is tempting as a wireless technology, and would be correct for pairing peripherals such as headsets or keyboards over short distances.
- ✗
802.11ac (Wi-Fi 5)
Why it's wrong here
802.11ac operates only on the 5 GHz band, so it cannot serve 2.4 GHz clients and predates Wi-Fi 6's OFDMA and uplink MU-MIMO, which specifically improve dense-environment performance. It is tempting because 802.11ac genuinely delivers high throughput, and would be correct for a straightforward 5 GHz upgrade where density is not the constraint.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A user is setting up a new wireless router at home. During configuration, they see options for Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax). Which standard offers faster speeds and better performance in congested environments?
easy- ✓ A.Wi-Fi 6
- B.Neither affects speed
- C.Both are identical in speed
- D.Wi-Fi 5
Why A: Wi-Fi 6 is the newer standard with higher data rates, improved efficiency, and better handling of multiple devices.
