After a customer completed the wireless network deployment on the existing network, all APs worked on the same channel, causing serious interference. Automatic radio frequency adjustment was enabled…

Question

Exhibit

Options

• AThe sensitivity of RF tuning is medium
• B2.4G tuned channel set is 1.6, 11
• CThe current tuning has ended
• DThe configured tuning mode is manual mode

• A
  5% (3)
• B
  2% (1)
• C
  84% (48)
• D
  9% (5)

Explanation

Option C contradicts what the command output actually shows: when you check "current tuning progress," the status displayed indicates the RF tuning is still in progress, not completed. Claiming it has "ended" misrepresents the live status shown in the CLI output - this is the incorrect statement among the four options.

Options A, B, and D are all accurate readings of the command output. The sensitivity setting of "medium" (A) is a standard RF tuning parameter displayed in the output. The 2.4G channel set of 1, 6, and 11 (B) represents the three standard non-overlapping 2.4GHz channels that automatic RF tuning cycles through - this is correct. The configured tuning mode being "manual" (D) is also a legitimate setting shown in the output, where the admin triggers tuning manually rather than on a time schedule.

Memory tip: Anchor on the word "progress" in the question stem - if you're checking tuning progress, the process is clearly still running. Any answer saying tuning is "done" or "ended" during a progress check will always be the trap option.
