The engineer logs in to the wireless controller web interface and checks the AP health details as shown in the figure below. The AP health value is only 30. Which of the following may be the reasons…

Question

Exhibit

Options

• AThe CPU utilization of 7 APs exceeds 20%
• BThe terminal access failure rate of 7 APs exceeds 20%.
• CThe number of users connected to 7 APs exceeds 40.
• D7 APs are in the online failure state

• A
  27% (7)
• B
  73% (19)

Explanation

Options B, C, and D all represent conditions that directly degrade AP health scores in enterprise wireless controllers: a terminal access failure rate above 20% signals that users are being denied service at a high rate; more than 40 users per AP indicates the AP is overloaded beyond its recommended capacity; and APs in an online failure state mean the hardware itself is unavailable - all three are weighted heavily in health calculations.

Option A is the distractor: a CPU utilization of 20% is well within the normal operating range for an AP. Health score penalties for CPU typically kick in at much higher thresholds (often 80%+), so moderate CPU load by itself would not cause a health value as low as 30.

Memory tip: Think of AP health as a "user experience" score - it drops when users can't connect (B), when APs are too crowded (C), or when APs are completely down (D). Normal background resource usage like moderate CPU load doesn't hurt the experience, so it doesn't hurt the score.
