In a WLAN network, the working status of the AP will be affected by the surrounding environment. By dynamically adjusting the AP's channel, power, and frequency band, each AP managed by the same TAC…

Options

• ADynamic frequency band adjustment
• BDynamic Bandwidth Selection
• CDynamic Power Scaling
• DDynamic channel adjustment

• A
  100% (36)

Explanation

All four options are correct because Huawei's Radio Frequency Automatic Tuning (RFAT) - managed per TAC (Traffic Access Controller) - encompasses exactly these four mechanisms working together to optimize AP performance.

• A (Dynamic Frequency Band Adjustment): APs can automatically switch between 2.4 GHz and 5 GHz bands based on interference levels and client load, maximizing spectrum efficiency.
• B (Dynamic Bandwidth Selection): Channel bandwidth (e.g., 20/40/80 MHz) is adjusted dynamically; narrower bandwidth reduces interference, while wider bandwidth boosts throughput when conditions allow.
• C (Dynamic Power Scaling): Transmit power is raised or lowered automatically to fill coverage gaps or reduce co-channel interference between neighboring APs.
• D (Dynamic Channel Adjustment): APs select the least congested channel automatically, avoiding interference from neighboring APs and external sources like microwaves or competing WLANs.

Since this is an all-correct question, there are no wrong distractors - the exam is testing whether you know the complete scope of the feature, not whether you can eliminate incorrect options.

Memory tip: Use the acronym FBPC - Frequency band, Bandwidth, Power, Channel. These are the four radio parameters RFAT can tune dynamically. If you remember "Huawei tunes the full radio stack," you'll recall all four.
