When an administrator manually adds a Mobility Controller (MC) on the Mobility Master (MM) hierarchy, which parameters must be specified? (Select three.)

An administrator migrates Aruba Mobility Controllers (MCs) from ArubaOS.6x to ArubaOS.8. x. In the 6.x.
configuration, the administrator configures GRE tunnels on the local controllers to a controller in the DMZ to keep guest traffic off the corporate network. The problem with the solution is that is creates suboptimal routing paths.
Which feature should the administrator implement to solve this problem?

An administrator manages an Aruba wireless network. Users authenticate to the wireless network using PEAP,where their credentials are validated by the controller's local database. The company purchases Android tablets to use with an inventory tracking system. The administrator notices that many of the users of these devices use their normal username and password to authenticate, which allows the tablet to access all resources that the user can access from their wireless computers. This is a security violation.
Which Aruba Mobility Controller (MC) feature should the administrator configure to restrict tablet access to a web portal for authentication, where an appropriate post-authentication policy can be applied to these tablets?

An administrator wants to change the default roles for the pre- and post-authentication user roles for a WLAN on a Mobility Master (MM). The controllers in the network perform all authentication.
Under the Managed Network hierarchy, where can the administrator assign these roles?

Which Aruba AP mode constantly scans the radioenvironment to gather IDS and RF information?
