A network administrator is designing a dual-band 802.11ax (Wi-Fi 6) wireless deployment for a high-density office building where neighboring tenant networks already occupy portions of the wireless spectrum. The administrator needs to optimize performance, minimize interference, and adhere to wireless standards best practices. Which of the following strategies should the administrator implement? (Select TWO.)
- Restrict the 2.4 GHz band to 20 MHz channel widths assigned exclusively to non-overlapping channels (1, 6, or 11).Cevap
- BConfigure 40 MHz channel bonding on the 2.4 GHz band using channels 3 and 9 to maximize throughput for legacy clients.
- Steer high-bandwidth dual-band devices to the 5 GHz band to take advantage of greater non-overlapping spectrum and wider channel options.Cevap
- DAssign adjacent 2.4 GHz channels such as 2, 5, and 8 to access points to increase overall wireless coverage density.
Cevap
The administrator should restrict the 2.4 GHz band to 20 MHz channel widths on non-overlapping channels (1, 6, or 11) and steer high-bandwidth dual-band devices to the 5 GHz band to leverage its expanded non-overlapping channel capacity.
Restricting 2.4 GHz Wi-Fi to 20 MHz channel widths on non-overlapping channels 1, 6, and 11 eliminates adjacent channel interference. Furthermore, directing high-capacity devices to the 5 GHz band takes advantage of significantly more non-overlapping channels, relieving 2.4 GHz congestion.
