  1. Investigate MAC contention separately from modulation robustness when identifying the bottleneck
  2. Check client MIMO capability before prescribing a larger channel width or a different cipher
  3. Compare client coding capability, bandwidth, resource scheduling and negotiated radio conditions
  4. Evaluate the negotiated MLO links instead of comparing marketing aggregate PHY rates

Explanation

Correct Answer

D:

A negotiated PHY rate depends on modulation, coding, streams and channel conditions and differs from application payload throughput. In the described case, evaluate the negotiated MLO links instead of comparing marketing aggregate PHY rates resolves the identified control gap. Confirm with: A supported client reports the active single link and its measured usable payload throughput.

Incorrect Answers

A:

This is relevant to a separate modulation, coding and phy rates problem: A VoIP fleet uses robust low-rate modulation yet voice packet loss persists because the shared channel is saturated. It does not directly address this incident, which instead calls for: Evaluate the negotiated MLO links instead of comparing marketing aggregate PHY rates.
