Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 108

What is the impact of configuring a single SSID to support TKIP and AES encryption simultaneously?

Answer options

• 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.

Correct answer: B

Explanation

Option B is correct because some wireless client drivers may not be compatible with the complexities of a dual encryption setup, resulting in connection issues. Options A, C, and D are incorrect as they either exaggerate the negative effects of the configuration or misrepresent its commonality and support status.
