What is the impact of configuring a single SSID to support TKIP and AES encryption simultaneously?
A.
The overhead associated with supporting both encryption methods degrades client throughput significantly.
B.
Some wireless client drivers might not handle complex SSID settings and may be unable to associate to the WLAN.
C.
This configuration is unsupported and the Cisco Wireless Control System generates alarms continuously until the configuration is corrected.
D.
This configuration is common for migrating from WPA to WPA2. No problem is associated with using this configuration.
Explanation:
I do not agree. Having both, means one or another. Not both at the same time. It depends on what is configured on the client. Any case, the best practice dictates that if both are configured in both sides, strogest will be used. Should not be conflict for client.
Correct answer should be the last one
