350-401 Question 158
Select 3A network administrator is tasked with designing a wireless network for a multi-story office building. The building experiences high interference from neighboring wireless networks and has areas with high device density. The administrator decides to use Cisco APs with Wi-Fi 6 capabilities. Which features of Wi-Fi 6 should the administrator leverage to address interference and device density challenges?
- A
Orthogonal Frequency Division Multiple Access (OFDMA)
- B
Target Wake Time (TWT)
- C
MU-MIMO (Multi-User, Multiple Input, Multiple Output)
- D
Beamforming
- E
Channel Bonding
Show answer and explanation
Correct answers: A, C, D
Explanation
Wi-Fi 6 includes features like OFDMA, MU-MIMO, and beamforming, which are tailored to improve wireless performance in environments with high device density and interference. OFDMA optimizes channel usage, MU-MIMO enhances simultaneous device communication, and beamforming reduces interference by focusing signal direction. These features make Wi-Fi 6 an ideal solution for the described scenario.
- A. Correct.
OFDMA allows multiple devices to share a single channel by dividing it into smaller resource units, improving efficiency in environments with high device density. This directly addresses the challenge of managing high device density.
- B. Incorrect.
TWT is a power-saving feature that schedules communication times for devices, reducing power consumption rather than addressing interference or density challenges.
- C. Correct.
MU-MIMO allows simultaneous communication with multiple devices, improving network performance in dense environments. This helps mitigate the challenge of device density.
- D. Correct.
Beamforming focuses the wireless signal in the direction of the client devices, enhancing signal quality and reducing interference from neighboring networks. This addresses interference challenges effectively.
- E. Incorrect.
Channel bonding combines multiple channels into a single wide channel to increase throughput, but it can increase interference in environments with neighboring networks, making it less suitable for this scenario.
