Question

Options

• AWhen the number of users accessing the AP reaches the starting threshold of spectrum
• BThrough the spectrum navigation function, the AP can control the terminal to access 5G first to
• CBefore the number of AP users reaches the starting threshold of spectrum navigation 5G priority,
• DThe two frequency bands of the AP that implement the spectrum navigation function must use the

• A
  22% (13)
• B
  78% (47)

Explanation

Spectrum navigation (also called band steering) is a wireless AP feature that actively guides dual-band clients toward the 5GHz band to optimize network performance.

Why B, C, and D are correct:

• B is correct because spectrum navigation works by the AP actively steering capable terminals to connect on 5GHz first, rather than leaving the band selection to the client - this is the core definition of the function.
• C is correct because the 5GHz priority steering operates proactively, before user count on 5G hits the congestion threshold; once that threshold is reached, the AP may stop enforcing 5G priority to avoid overloading the band.
• D is correct because for spectrum navigation to work, both the 2.4GHz and 5GHz radios on the AP must use the same SSID - this is a prerequisite that allows the AP to transparently redirect clients between bands.

Why A is wrong: A inverts the logic - spectrum navigation does not activate only after the user count reaches the threshold; it applies before the threshold to keep 5GHz preferred, and it is the threshold breach that can suspend 5G prioritization, not trigger it.

Memory tip: Think of spectrum navigation as a "5G bouncer" - it steers clients to the 5G VIP section before it fills up, and stops once it's full. Both doors (bands) must carry the same name (SSID) for the bouncer to redirect guests seamlessly.
