Question2: An administrator manages an Aruba wireless solution, deployed in a company with locations across the world. In one country, the local government organization that controls wireless transmissions increases the maximum EIRP allowed for certain channels.
Which component does the administrator need to update on the Mobility Master (MM) to accommodate this change?

Question3: Which VPN component must be configured on the Mobility Master (MM) to allow a RAP to use the built-in certificate to successfully connect to a Mobility Controller (MC)?

Question4: An administrator has a standalone controller that runs ArubaOS 8.x software and wants to upgrade it to a newer release. The upgrade will be performed from the front panel of the physical controller. The administrator places the new software in the root directory of a USB drive. On the controller's LCD panel, no image is found.
What is the cause of this problem?

Question5: Refer to the exhibit.

An administrator supports a RAP at a branch office shown in the exhibit. The company has one Mobility Controller (MC) at the Primary DMZ site and one at the Secondary DMZ site. The RAP is configured to connect to only the MC at the Primary DMZ site. A network outage with the ISP at the Primary DMX site causes the RAP to reboot. Upon reboot, the RAP cannot build a tunnel to the Secondary DMZ site MC because the administrator forgot to add the Second LMS IP address to the AP Group configuration.
