                                          NEW QUESTION # 86
                                          Which command set configures a Cisco Catalyst 9800 Series Wireless Controller so that the client traffic enters the network at the AP switch port?

                                          Answer: C

                                          Explanation:
                                          On the Catalyst 9800, the point at which client traffic enters the wired network is controlled in the policy profile. The command context is wireless profile policy, followed by the profile name. Inside that context, no central switching tells the controller that clients of the WLANs mapped to this policy are switched locally at the AP, so their traffic enters the network at the AP switch port instead of being tunnelled in CAPWAP to the WLC. This normally goes together with no central dhcp and no central association for FlexConnect sites, and the AP must be in FlexConnect mode, which is achieved through the Flex profile and site tag. The command keyword local switching does not exist in the policy profile. Likewise, wireless flexconnect policy is not a valid configuration context on this platform. The Flex profile is created with wireless profile flex, and the switching behaviour is not set there. The only option that uses the correct context and the correct command is the set with wireless profile policy and no central switching.
                                          Reference: Blueprint 1.1 (FlexConnect switching); Cisco Catalyst 9800 Series Software Configuration Guide, FlexConnect and policy profile. Source key listed C; corrected to D (see appendix).


                                          NEW QUESTION # 87
                                          A network engineer created a new wireless network that will be used for guest access. The corporate network must utilize all rates. The guest network must use only lower rates instead of 802.11n data rates. To what must the WMM policy of the WLAN be set to accomplish this task?

                                          Answer: B

                                          Explanation:
                                          Wi-Fi Multimedia is part of the 802.11e QoS mechanism, and the 802.11n and later high-throughput rates require WMM to be active. A WLAN on which WMM is disabled therefore does not allow the high- throughput data rates, and clients on it operate with the legacy rates only. The task asks for a guest network that must stay with lower rates while the corporate network uses all rates, which is exactly what is obtained when the WMM policy of the guest WLAN is set to Disabled. The other values keep high-throughput operation possible. Allowed lets WMM-capable clients use WMM and others connect without it, and Required forces clients to support WMM, so both leave the 802.11n rates available. Mandatory is not a WMM policy value on the controller. The trade-off is that guest traffic loses WMM prioritisation, which suits a deliberately low-priority network. Keep in mind that disabling WMM also removes prioritisation for the clients on that WLAN, which is acceptable for guests but not for voice or video networks.
                                          Reference: Blueprint 2.2 (Implement QoS for wireless clients); Cisco Catalyst 9800 Series Software Configuration Guide, WMM policy on a WLAN.


                                          NEW QUESTION # 88
                                          When deploying BYOD (bring your own device) access, what are the two common methods of guest portal onboarding and authentication?

                                          Answer: B,C


                                          NEW QUESTION # 89
                                          Suppose a customer wants potential users to enter a username and password before being granted access to the wireless network.
                                          Which of the following items could you add to the list of requirements for your wireless design to meet the customer's requirement?

                                          Answer: A,B,D


                                          NEW QUESTION # 90
                                          A wireless administrator must assess the different client types connected to Cisco Catalyst 9800 Series Wireless Controller without using any external servers. Which configuration must be added to the controller to achieve this assessment?

                                          Answer: B

                                          Explanation:
                                          Local profiling on the Catalyst 9800 does not need an external server. The Cisco profiling document explains that device classification is enabled globally on the controller, after which the controller collects information from the clients, DHCP and HTTP data and the OUI of the MAC address, and builds a device profile. The result is visible in the client details, where the device type, name and class can be seen, and it can be used by local policies. The same global setting is also a prerequisite for RADIUS profiling. For a wireless administrator who wants an overview of the client types on the controller, device classification is therefore the configuration that has to be added. The terms native profile, MAC classification and local profile are not the names of the controller configuration items that perform this task, so they cannot be used to obtain the assessment. After the setting is applied, the profiled clients are visible in the monitoring section of the controller, where each client shows its detected device type.
                                          Reference: Blueprint 6.1 (Configure client profiling on WLC and ISE); Cisco, Demonstrate Client Profiling on 9800 Wireless LAN Controller.
