A network administrator has racked up a 7210 Mobility Controller (MC) that will be terminating 200+ Aps on a medium-size branch office. Next, the technician cabled the appliance with 4SPF+ Direct Attached Cables (DACs) distributed between two-member switching stack and powered it up. What must the administrator do next in the MCs to assure maximum wired bandwidth utilization?

Refer to the exhibits. 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?

A fully functional WLAN is deployed in a campus network using the following script. Which part of the script can a network administrator re-use to assign a different default role to users when they connect to the same SSID in a second building?

An Aruba WiFi solution for a football stadium includes 2500 APs, two Mobility Masters (MM) , and eight Mobility Controllers (MCs) . Key requirements are seamless roaming and even distribution of APs and clients, even during a MC failure. Which MC's deployment option offers seamless roaming, and even AP client distribution among all MCs before and after a MC failure?

A network administrator has updated the ArubaOS code of a standalone Mobility Controller (MC) that is used for User-Based Tunneling (UBT) to a newer early release. Ever since the MC seems to reject PAPI sessions from the switch with the 10.1.10.10 IP address. Also the controller's prompt is now followed by a star mark: "(MC_VA) [mynode] *#" When opening a support ticket, an Aruba TAC engineer asks the administrator to gather the crash logs and if possible replicate UBT connection attempts from the switch while running packet captures of PAPI traffic on the controller and obtain the PCAP files. The administrator has a PC with Wireshark and TFTP server using the 10.0.20.20 IP address. What commands must the administrator issue to accomplish these requests? (Choose two.)

A company with 535 users deploys an Aruba solution with more than 1000 Aruba APs, two 7220 Mobility Controllers, and a single Mobility Master (MM) virtual appliance at the campus server farm. The MCs run a HA Fast failover group in dual mode and operate at 50% AP capacity. If there is an MM or MC failure, the network administrator must ensure that the network is fully manageable and the MC load does not exceed 80%. What can the network administrator do to meet these requirements?

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 exhibits. Exhibit 1 Exhibit 2 Exhibit 3 Exhibit 4 A captive portal-based solution is deployed in a Mobility Master (MM) - Mobility Controller (MC) network. A wireless station connects to the network and attempts the authentication process. The outputs are shown in the exhibits. Which names correlate with the authentication and captive portal servers?

Refer to the exhibits. Exhibit 1 Exhibit 2 Exhibit 3 A network administrator wants to allow contractors to access the corporate WLAN named EmployeesNet with the contractor role in VLAN 40. When users connect, they do not seem to get an IP address. After some verification checks, the network administrator confirms the DHCP server (10.254.1.21) is reachable from the Mobility Controller (MC) and obtains the outputs shown in the exhibits. What should the network administrator do next to troubleshoot this problem?

Users run Skype for Business on wireless clients with no WMM support over an Aruba Mobility Master (MM) - Mobility Controller (MC) based network. When traffic arrives at the wired network, it does not include either L2 or L3 markings. Which configuration steps should the network administrator take to classify and mark voice and video traffic with UCC heuristics mode?
