Q61. Which two statements best describe the LAG configuration between a Cisco WLC and a Cisco Catalyst switch? (Choose two.)
A. The Catalyst switch should be configured for PAgP.
B. The Catalyst switch should be configured only for Layer 2 load balancing.
C. The Catalyst switch should be configured for "on" mode.
D. The Cisco WLC relies on the connected switch to perform the load-balance of traffic.
E. The Cisco WLC aggregates multiple management interfaces into a single virtual interface.
Q62. Which operating mode is valid for controllers in a converged access architecture?
A. switch peer groups
B. mobility controller
D. foreign anchor
Q63. 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.
Q64. Refer to the exhibit.
What does the yellow shield with the exclamation mark indicate?
A. The network uses open authentication and no encryption.
B. The network uses an unsupported channel.
C. The signal is too distorted to connect.
D. The AP that is transmitting this SSID uses the wrong RF domain.
E. This is the ad-hoc network.
Q65. A customer has asked for its wireless equipment to be managed as securely as possible. Which three management protocols will provide encrypted access to the equipment? (Choose three.)
A. Secure Shell
Q66. An 802.11g network is experiencing intermittent signal degradation and Spectrum Analyzer is being used to try and locate the problem. What two interferers would likely be identified? (Choose two.)
A. multiple cell phones
B. microwave oven
C. FM Radio
D. cordless phone
E. document scanner
Q67. A Cisco Aironet 1260 AP is unable to join a Cisco 2500 Series WLC that is connected through a Layer 2 switch.

Q69. What is the difference between the IEEE, the WiFi Alliance, and the FCC, ETSI, and TELEC?
A. The IEEE and FCC are responsible for the standards that apply to wireless networks. The WiFi Alliance, ETSI, and TELEC are the governmental agencies that regulate compliance with local standards.
B. The IEEE is responsible for Layer 1 and Layer 2 protocols. The WiFi Alliance is responsible for interoperability testing. The FCC, ETSI, and TELEC are responsible for radio frequency and transmission power-level regulations and standards in the U.S., Europe, and Japan.
C. The IEEE is responsible for Layer 1 and Layer 2 protocols. The FCC, ETSI, and TELEC are responsible for interoperability testing and compliance. The WiFi Alliance is responsible for radio frequency and transmission power-level regulations and standards on a global basis.
D. The IEEE and FCC are responsible for the Layer 3 protocol support and frequency and power-level regulations in the United States. ETSI and TELEC are responsible for frequency and power-level regulations in Europe and Japan. The WiFi Alliance is responsible to interoperability testing.
