A customer is deploying Huawei's cloud management solution on their existing network. All cloud APs are now online, but all APs are working on the same channel, causing serious interference. When…

Question

Options

• ACloud APs belong to different sites
• BThe Leader group is not established.
• CChannel or power configuration is fixed mode
• DThe AP is not tuned.

• A
  81% (17)
• D
  19% (4)

Explanation

RF calibration in Huawei's cloud management platform (e.g., CloudCampus/iMaster NCE) requires APs to share the same site - calibration is scoped per-site, so APs across different sites cannot participate in a unified calibration group (A). The calibration algorithm also depends on a Leader AP/group being established to collect neighbor scan data and coordinate channel/power assignments across nearby APs; without it, no negotiation occurs (B). If channel or power settings are in fixed/manual mode, the calibration engine has no authority to override them, rendering any triggered calibration ineffective (C). Option D ("AP is not tuned") is incorrect because AP tuning status is not a recognized prerequisite for RF calibration in Huawei's cloud platform - APs being online (as stated in the question) is sufficient for participation.

Memory tip: Think of the three letters as "SAF" blockers - Site mismatch, Absent leader (group), Fixed mode - any one of these "SAF" conditions blocks calibration from applying.
