QUESTION: 1 After an autonomous Cisco Aironet 1200 Access Point has been converted to LWAPP mode, which two statements are true? (Choose two.) A. LWAPP-enabled access points can still communicate with Wireless Domain Services (WDS) devices. B. An LWAPP-enabled access point console port provides read-only access to the unit. C. LWAPP-enabled access points support Layer 2 LWAPP. D. LWAPP-enabled access points must get an IP address and discover the controller using DHCP, DNS, or an IP subnet broadcast. E. An LWAPP-enabled access point console port provides read-write access to the unit. Answer: B, D Explanation: Some of the restrictions that are imposed on a Cisco IOS Software-based AP after conversion to lightweight mode include the following: Reference: cisco/en/US/products/hw/wireless/ps430/products_qanda_item09186a00806a4da3. sht ml QUESTION: 2 Which statement is true about the data traffic between the access point and controller? A. The data traffic between the access point and controller is not encrypted. B. The data traffic is encapsulated with LWAPP. C. The data traffic is switched at the access point before being sent to the WLAN controller where VLAN tagging and QoS are applied. D. The data traffic is encrypted with AES. E. All of the above Answer: B Explanation: The LAP and WLC pair use the lightweight access point protocol (LWAPP) as the tunneling mechanism. LWAPP control messages—Exchanges that are used to configure the LAP and manage its operation. The control messages are authenticated and encrypted so that the LAP is securely controlled by only the WLC. LWAPP data—Packets to and from wireless clients associated with the LAP. The data is encapsulated within LWAPP, but is not encrypted or otherwise secured between the LAP and WLC. Data traffic between Access Point(AP) and Controller is encapsulated with LWAPP. 642-813 2 troytec QUESTION: 3 Which set of statements describes the correct order and process of a wireless client associating with a wireless access point?
