You are investigating a report of poor wireless performance in a network that you manage. The issue is related to an AP interface in the 5 GHz range. You are monitoring the channel utilization over time.
What is the recommended maximum utilization value that an interface should not exceed?
For optimal performance in a wireless network, the recommended maximum channel utilization value for an interface in the 5 GHz range should not exceed 75%. Exceeding this threshold can lead to congestion, reduced performance, and increased latency. Therefore, 75% is generally considered the upper limit for maintaining good wireless performance.
C is correct answer as per study guide page 444
C - Max rec - Utilization is 75%, P444 Study guide
