CCNP 350-401 ENCOR Question 137 DISCUSSION
« Back to Main MenuWireless users report frequent disconnections from the wireless network. While troubleshooting, a network engineer finds that after the user is disconnected, the connection re-establishes automatically without any input required. The engineer also notices these message logs:
AP 'AP2' is down. Reason: Radio channel set. 6:54:04 PM
AP 'AP4' is down. Reason: Radio channel set. 6:44:49 PM
AP 'AP7' is down. Reason: Radio channel set. 6:34:32 PM
Which action reduces the user impact?
A. increase the dynamic channel assignment interval
B. increase BandSelect
C. increase the AP heartbeat timeout
D. enable coverage hole detection

C. increase the AP heartbeat timeout
D. enable coverage hole detection
Correct Answer: A
These message logs inform that the radio channel has been reset (and the AP must be down briefly). With dynamic channel assignment (DCA), the radios can frequently switch from one channel to another but it also makes disruption. The default DCA interval is 10 minutes, which is matched with the time of the message logs. By increasing the DCA interval, we can reduce the number of times our users are disconnected for changing radio channels
