- 8. Multiple Choice
A network administrator is configuring a RADIUS server connection on a Cisco 3500 series WLC. The configuration requires a shared secret password. What is the purpose for the shared secret password?
It allows users to authenticate and access the WLAN.
It is used by the RADIUS server to authenticate WLAN users.
It is used to authenticate and encrypt user data on the WLAN.
It is used to encrypt the messages between the WLC and the RADIUS server.
- 9. Multiple Choice
A network engineer is troubleshooting a newly deployed wireless network that is using the latest 802.11 standards. When users access high bandwidth services such as streaming video, the wireless network performance is poor. To improve performance the network engineer decides to configure a 5 Ghz frequency band SSID and train users to use that SSID for streaming media services. Why might this solution improve the wireless network performance for that type of service?
The 5 GHz band has a greater range and is therefore likely to be interference-free.
Requiring the users to switch to the 5 GHz band for streaming media is inconvenient and will result in fewer users accessing these services.
The 5 GHz band has more channels and is less crowded than the 2.4 GHz band, which makes it more suited to streaming multimedia.
The only users that can switch to the 5 GHz band will be those with the latest wireless NICs, which will reduce usage.
- 10. Multiple Choice
Which step is required before creating a new WLAN on a Cisco 3500 series WLC?
