Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 45

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

Answer options

• 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 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 certain wireless client drivers may not support complex configurations, leading to connection issues. Option A is incorrect as it does not specifically address the client driver compatibility issue. Option C is false because the configuration is not inherently unsupported; it may just lead to potential problems. Option D is misleading since while common, it does not guarantee that all clients will work without issues.
