CWDP Wireless Network Troubleshooting

Question 1

What is the most common cause of sticky client behavior in enterprise WLANs?

Accepted Answer

Clients maintaining association with a distant AP instead of roaming to a closer one

Answer

Clients frequently disconnecting and reconnecting

Answer

Excessive DHCP lease times

Answer

Too many SSIDs configured on the network

Question 2

How can excessive co-channel interference (CCI) be identified during troubleshooting?

Accepted Answer

High retry rates and low throughput despite strong signal levels

Answer

Complete loss of wireless connectivity

Answer

Clients unable to authenticate

Answer

DHCP server not responding

Question 3

What tool is best suited for identifying non-Wi-Fi interference sources?

Accepted Answer

Spectrum analyzer

Answer

Protocol analyzer (packet capture)

Answer

Wi-Fi scanner application

Answer

Ping utility

Question 4

What does a high percentage of management frames indicate in a wireless packet capture?

Accepted Answer

Possible network instability with frequent client associations, disassociations, or probe requests

Answer

A well-optimized network

Answer

High data throughput

Answer

Encrypted traffic that cannot be analyzed

Question 5

What is the recommended approach when users report intermittent connectivity issues?

Accepted Answer

Correlate the timing with potential interference sources, check client roaming behavior, and verify AP health

Answer

Immediately replace all access points

Answer

Increase transmit power on all APs to maximum

Answer

Reboot the wireless controller

Question 6

How does transmit power mismatch between APs and clients affect network performance?

Accepted Answer

Clients may hear the AP but cannot transmit back reliably, creating asymmetric communication

Answer

It causes the AP to overheat

Answer

It has no effect on performance

Answer

It only affects battery life on the client device
