A company has purchased some new Aruba switches and APs and wants to manage these in Aruba Central. Where would the company’s administrator navigate in order to manually assign subscription licenses for these new devices?. Aruba Activate. Aruba Central dashboard. Aruba Central device configuration page. HPE GreenLake dashboard.

A small company wants to dynamically provision ports when devices are connected to them, like VoIP phones, security cameras, and APs. The company is not using Central for management and does not have an AAA server. What profiling configuration must the administrator create to define settings like VLAN, QoS trust mode, and security polices to these ports dynamically?. Device profiles. Aruba user roles. LLDP Group. SNMP Group.

An administrator is using Central to manage APs that were newly added. The APs were at their factory default configuration. The administrator wants to place these APs on floorplans in Central; however, the administrator only sees the AP names as MAC addresses, and thus doesn’t know which AP is which when assigning them to the floorplan location. What command on the AP console can the administrator use to see the AP’s MAC address and serial number from its boot mode?. show version. mfginfo. show system. show serial-info.

What technology is used to implement multi-user MIMO, such that multiple signals can be generated from an antenna simultaneously?. Beamforming. Airmatch. SISO. Azimuth.

From the username and password prompt, press <Cntrl>P and select the admin account. Reboot the switches and change the password from the Service OS console.

An administrator was using Aruba Central to configure AOSCX switches. The administrator made a VLAN configuration mistake for a group of switches, pushing the incorrect native VLAN to these switches. This misconfiguration caused the switches to lose access to Central. The administrator fixed the template configuration in Central with the correct native VLAN, but the AOS-CX switches still cannot connect to Central. The switches’ rollback feature was not implemented. What should the administrator do to fix this issue?. Boot to the Service OS Console and enable the Central recovery option. Enter lockout mode on the switches and manually fix the native VLAN on the trunk port. Enable disaster recovery mode on the switches and manually fix the native VLAN on the trunk port. Execute the show aruba-central command and wait for a connection failure. Then manually fix the native VLAN on the trunk port.
