Question 1 of 54

Which of the following is the first WLAN standard defined by IEEE?
Answer choices
Show answer

Correct answer: A

IEEE 802.11 is the original WLAN standard defined by IEEE, establishing the basic wireless LAN architecture and operation in the 2.4 GHz band. It provides the foundation for later amendments that improve speed, frequency usage, and modulation methods. IEEE 802.11a, 802.11b, and 802.11g are subsequent extensions of the original 802.11 standard.

Question 2 of 54

Which of the following 802.11 standards use orthogonal frequency division multiplexing (OFDM) technology? (Choose all that apply.)
Answer choices
Show answer

Correct answers: A, D, E, F

802.11a, 802.11g, 802.11n, and 802.11ac use OFDM to divide a wireless channel into multiple orthogonal subcarriers, improving resistance to multipath interference and supporting higher data rates. 802.11n extends OFDM with MIMO, while 802.11ac further increases channel widths and modulation efficiency. In contrast, legacy 802.11 and 802.11b use FHSS or DSSS rather than OFDM.

Question 3 of 54

Which of the following are PHY technologies used by 802.11ac? (Choose all that apply.)
Answer choices
Show answer

Correct answers: C, D, E

802.11ac uses OFDM as its fundamental modulation framework and adds 256-QAM to increase the number of bits transmitted per subcarrier, improving peak throughput. It also supports downlink MU-MIMO, allowing an access point to transmit separate spatial streams to multiple clients at the same time. OFDMA is introduced with 802.11ax, while RTS/CTS and A-MPDU are MAC-layer mechanisms rather than 802.11ac PHY technologies.

Question 4 of 54

MIMO beamforming adjusts the phase of radio signals at the transmit end to increase the received signal strength indicator (RSSI).
Answer choices
Show answer

Correct answer: A

MIMO beamforming adjusts the phase, and often the amplitude, of signals transmitted from multiple antennas so they combine constructively at the intended receiver. This concentrates radio energy in the receiver’s direction, improving received signal strength and typically improving link quality. It relies on coordinated antenna transmissions rather than simply increasing transmit power.

Question 5 of 54

A WLAN that deploys Wi-Fi 6 products delivers a higher speed than that with Wi-Fi 5 products deployed.
Answer choices
Show answer

Correct answer: A

Wi-Fi 6 introduces efficiency and throughput improvements such as OFDMA, uplink and downlink MU-MIMO, and higher-order modulation. These capabilities allow more data to be transmitted efficiently, particularly when many users share the WLAN. As a result, a WLAN using Wi-Fi 6 products can deliver higher speeds than one using Wi-Fi 5 products.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.

Morgan Farmer

I don't usually leave reviews, but this one felt worth sharing. The questions were quite close to what actually appeared on the exam, more than I expected. I spent about a week going through the material before my test, and it helped me feel more prepared.
Remi Nuyts
United States
Passed ITIL 4 Foundation with 87%. Material was enough by itself.
Archie Hopkins
United States
I had a smooth experience from start to finish. Access was available right away, no technical issues, which made it easy to get started. The content felt relevant and aligned well with what I was looking for.
Nancy Mcbride
United States
Does what it says it does. Content felt solid, nothing confusing to navigate and I didn't run into any weird issues. I been putting off scheduling the exam for a while and going through this gave me enough confidence to finally book it and pass.
Neil Savage
United States
A very quick response was received via email when a link issue occurred. The study materials provided were high quality and extremely helpful. I was able to complete the test successfully. Many thanks for the excellent support.
