Based on the output shown in the exhibit, which channel offers the highest quality?

A software development company has 764 employees who work from home. The company also has small offices located in different cities throughout the world. During working hours, they use RAPs to connect to a datacenter to upload software code as well as interact with databases.
In the past two month, cabling issues have occurred connection to the 7240XM Mobility Controller (MC) that runs ArubaOS 8 and terminates the RAPs. These RAPs disconnect, affecting the users connected to the RAPs. This also causes problems with code uploads and database synchronizations. Therefore, the company decides to add a second 7240XM controller for redundancy.
How should the network administrator deploy both controllers in order to provide the redundancy while preventing failover events from disconnecting users?

Refer to the exhibit.

An organization provides WiFi access through a corporate SSID with an Aruba Mobility Master (MM) - Mobility Controller (MC) network that includes PEF functions. The organization wants to have a single firewall policy configured and applied to the employee role.
This policy must allow users to reach Web, FTP, and DNS services, as shown in the exhibit. Other services should be exclusive to other roles. The client NICs should receive IP settings dynamically.
Which policy design meets the organization's requirements while minimizing the number of policy rules?

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 customer wants a WLAN solution that permits Aps to terminate WPA-2 encrypted traffic from different SSIDs to different geographic locations where non-related IT departments will take care of enforcing security policies. A key requirement is to minimize network congestion, overhead, and delay while providing data privacy from the client to the security policy enforcement point. Therefore, the solution must use the shortest path from source to destination.
Which Aruba feature best accommodates this scenario?
