   A university library provides guest Wi-Fi. The library staff have complained that a few users are streaming high-definition video, consuming most of the bandwidth and degrading the experience for other guests. The network administrator needs to limit the bandwidth available to each guest client to 5 Mbps downlink and 2 Mbps uplink, while still allowing normal web browsing. The wireless network uses Cisco Catalyst 9800 controllers. What is the most efficient way to enforce this limit?

   • AConfigure a WLAN QoS profile with a bandwidth limit and assign it to the guest SSID.
   • BEnable WMM admission control on the guest WLAN to restrict video streaming.
   • CUse an access control list on the controller to drop traffic from clients that exceed 5 Mbps.
   • DCreate a per-client QoS policy with a bandwidth contract and apply it to the guest WLAN's policy profile.

   A law firm's wireless network carries both confidential document transfers and video conferencing traffic. The firm's security policy requires that all traffic be encrypted, and the network team wants to ensure that video conferencing is prioritized. The video conferencing application is not DSCP-marked by the client. The network uses Cisco Catalyst 9800 controllers with WMM enabled. Which approach will ensure video conferencing is prioritized without compromising security?

   • ATrust the DSCP markings from the video conferencing clients, assuming they will mark their traffic correctly.
   • BEnable WMM admission control on the WLAN to reserve bandwidth for video conferencing.
   • CConfigure a per-client QoS policy that gives the video conferencing clients a higher bandwidth limit.
   • DConfigure an application-based QoS policy that matches the video conferencing application and marks it with DSCP AF41, then attach the policy to the policy profile.

   A small office uses a single WLC and several APs. The administrator wants to enable QoS for wireless clients but is concerned about compatibility with older 802.11g clients. What should the administrator do?

   • AEnable WMM on the WLAN and ensure that all APs have WMM enabled.
   • BDisable WMM on the WLAN to avoid compatibility issues with older clients.
   • CSet the WLAN to use only 802.11n/ac to ensure all clients support WMM.
   • DEnable WMM only on the APs that serve newer clients.
