Which statement about the impact of configuring a single SSID to support TKIP and AES encryption simultaneously is true?

Which statement about the impact of configuring a single SSID to support TKIP and AES encryption simultaneously is true?
A . The overhead associated with supporting both encryption methods significantly degrades client throughput.
B . Some wireless client drivers might not handle complex SSID settings and may be unable to associate to the WLA
D . This configuration is unsupported and the Cisco Wireless Control System generates alarms continuously until the configuration is corrected.
E . This configuration is common for migrating from WPA to WPA2. No problem is associated with using this configuration.

Answer: B

Explanation:

AES encryption uses hardware so there is almost no overhead when using it. TKIP is based on software. So when we support both TKIP and AES the client throughput will not significantly degrade -> A is not correct. When choosing both AES and TKIP, the router will support both encryption algorithms. Because not all wireless NICs support AES, some only support TKIP, so this option is probably the best choice -> B is not correct. As the picture below, Cisco Wireless Control System does support both simultaneously -> C is not correct.
