A user reports slow connectivity to a network administrator when connecting to AP-Garden and suggests that there might be a problem with the WLAN. The user's device supports 802.11n in the 2.4 GHz band. The network administrator finds the user in the Mobility Master (MM) and reviews the output shown in the exhibit.
What can the network administrator conclude after analyzing the data?
Refer to the exhibit.
Based on the output shown in the exhibit, which channel offers the highest quality?
A network administrator wants to permit explicit SSH, FTP and HHTP(s) access to servers in the 10.100.20.5 to 10.100.20.31 range, all devices in 10.100.21.0/24 network, and a host with IP address 10.100.22.70. The services must work properly at all times.
Which configuration scripts accomplish this task with the fewer number of lines, while avoiding access to other devices not included in these ranges? (Choose two.)
Refer to the exhibit.
A network administrator has recently enabled WMM on the VAP's SSID profile and enabled UCC Skype4B ALG at the Mobility Master level. During testing, some voice and video conference calls were made, and it was concluded that the call quality has dramatically improved. However, end to end information isn't displayed in the call's details. Also, Skype4B app-sharing's performance is poor at times.
What must the administrator do next in order to enable end to end call visibility and QoS correction to app-sharing service?
Refer to the exhibit.
A network administrator completes the initial configuration dialog of the Mobility Controllers (MCs) and they join the Mobility Master (MM) for the first time. After the MM-MC association process, network administrator only creates AP groups, VAPs, and roles. Next, the network administrator proceeds with the configuration of the policies and creates the policy shown in the exhibit.
Which additional steps must be done to make sure this configuration takes effect over the contractor users?
