You have been getting reports of voice disruption over wireless communications in your network. Your SSID is configured to use WPA1 with TKIP and Cisco Centralized Key Management. You see a lot of TKIP replay messages on the WLC logs.
What is the most probable reason for the voice disruptions?
A. TKIP replay causes access point to reboot as a security measure. This causes voice disruptions for the associated clients until they scan and reconnect to another AP.
B. The TKIP countermeasure timer is putting the AP down for a specified time and causing the voice disruptions.
C. TKIP replay activates MFP. If MFP detects the replays, it will trigger a disassociation to all wireless clients.
D. The use of WPA1 with TKIP is the main reason for the voice disruptions. It is better to use WPA2 with AES to avoid this problem.
